Ireland (local pronunciation: [ˈaɪrlənd] ( listen); Irish: Éire [ˈeːɾʲə] ( listen); Ulster-Scots: Airlann or Airlan) is an island to the north-west of continental Europe. It is the third-largest island in Europe and the twentieth-largest island on Earth. To its east is the larger island of Great Britain, from which it is separated by the Irish Sea.
Politically, Ireland is divided between the Republic of Ireland, which covers just under five-sixths of the island, and Northern Ireland, a part of the United Kingdom, which covers the remainder and is located in the north-east of the island. The population of Ireland is approximately 6.4 million. Just under 4.6 million live in the Republic of Ireland and just under 1.8 million live in Northern Ireland.
Relatively low-lying mountains surrounding a central plain epitomise Ireland's geography with several navigable rivers extending inland. The island has lush vegetation, a product of its mild but changeable oceanic climate, which avoids extremes in temperature. Thick woodlands covered the island until the 17th century. Today, it is one of the most deforested areas in Europe. There are twenty-six extant mammal species native to Ireland.
A Norman invasion in the Middle Ages gave way to a Gaelic resurgence in the 13th century. Over sixty years of intermittent warfare in the 1500s led to English dominance after 1603. In the 1690s, a system of Protestant English rule was designed to materially disadvantage the Catholic majority and Protestant dissenters, and was extended during the 18th century. In 1801, Ireland became a part of the United Kingdom. A war of independence in the early 20th century led to the partition of the island, creating the Irish Free State, which became increasingly sovereign over the following decades. Northern Ireland remained a part of the United Kingdom and saw much civil unrest from the late 1960s until the 1990s. This subsided following a political agreement in 1998. In 1973, both parts of Ireland joined the European Economic Community.
Irish culture has had a significant influence on other cultures, particularly in the fields of literature and, to a lesser degree, science and education. A strong indigenous culture exists, as expressed for example through Gaelic games, Irish music and the Irish language, alongside mainstream Western culture, such as contemporary music and drama, and a culture with much in common with Great Britain, as expressed through sports such as soccer, rugby, horse racing, and golf, as well as the English language.
Most of Ireland was covered with ice until the end of the last ice age over 9,000 years ago. Sea levels were lower and Ireland, like Great Britain, was part of continental Europe. Mesolithic stone age inhabitants arrived some time after 8,000 BC and agriculture followed with the Neolithic Age around 4,500 to 4,000 BC when sheep, goats, cattle and cereals were imported from the Iberian peninsula.
At the Céide Fields, preserved beneath a blanket of peat in present-day County Mayo, is an extensive field system, arguably the oldest in the world, dating from not long after this period. Consisting of small divisions separated by dry-stone walls, the fields were farmed for several centuries between 3,500 and 3,000 BC. Wheat and barley were the principal crops.
The Bronze Age – defined by the use of metal – began around 2,500 BC, with technology changing people's everyday lives during this period through innovations such as the wheel, harnessing oxen, weaving textiles, brewing alcohol, and skillful metalworking, which produced new weapons and tools, along with fine gold decoration and jewellery, such as brooches and torcs. According to John T. Koch and others, Ireland in the Late Bronze Age was part of a maritime trading-networked culture called the Atlantic Bronze Age that also included Britain, France, Spain and Portugal where Celtic languages developed.
The Iron Age in Ireland is traditionally associated with people known as the Celts. The Celts were commonly thought to have colonised Ireland in a series of invasions between the 8th and 1st centuries BC. The Gaels, the last wave of Celts, were said to have divided the island into five or more kingdoms after conquering it. However, some academics favour a theory that emphasises the diffusion of culture from overseas as opposed to a military colonisation. Finds such as Clonycavan Man are given as evidence for this theory.
Late antiquity and early medieval times
The earliest written records of Ireland come from classical Greco-Roman geographers. Ptolemy in his Almagest refers to Ireland as Mikra Brettania (Lesser Britain), in contrast to the larger island, which he called Megale Brettania (Great Britain). In his later work, Geography, Ptolemy refers to Ireland as Iouernia and to Great Britain as Albion. These "new" names were likely to have been the Celtic names for the islands at the time. The earlier names, in contrast, were likely to have been coined before direct contact with local peoples was made.
The Romans would later refer to Ireland by this name too in its Latinised form, Hibernia, or Scotia. Ptolemy records sixteen tribes inhabiting every part of Ireland in 100 AD. The relationship between the Roman Empire and the tribes of ancient Ireland is unclear. However, a number of finds of Roman coins have been found, for example at New Grange.
Ireland continued as a patchwork of rival tribes but, beginning in the 7th century AD, a concept of national kingship gradually became articulated through the concept of a High King of Ireland. Medieval Irish literature portrays an almost unbroken sequence of High Kings stretching back thousands of years but modern historians believe the scheme was constructed in the 8th century to justify the status of powerful political groupings by projecting the origins of their rule into the remote past.
The High King was said to preside over the patchwork of provincial kingdoms that together formed Ireland. All of these kingdoms had their own kings but were at least nominally subject to the High King. The High King was drawn from the ranks of the provincial kings and ruled also the royal kingdom of Meath, with a ceremonial capital at the Hill of Tara. The concept only became a political reality in the Viking Age and even then was not a consistent one. However, Ireland did have a unifying rule of law: the early written judicial system, the Brehon Laws, administered by a professional class of jurists known as the brehons.
The Chronicle of Ireland records that in 431 AD Bishop Palladius arrived in Ireland on a mission from Pope Celestine I to minister to the Irish "already believing in Christ." The same chronicle records that Saint Patrick, Ireland's best known patron saint, arrived the following year. There is continued debate over the missions of Palladius and Patrick but the consensus is that they both took place and that the older druid tradition collapsed in the face of the new religion. Irish Christian scholars excelled in the study of Latin and Greek learning and Christian theology. In the monastic culture that followed the Christianisation of Ireland, Latin and Greek learning was preserved in Ireland during the Early Middle Ages in contrast to elsewhere in Europe, where the Dark Ages followed the decline of the Roman Empire.
The arts of manuscript illumination, metalworking and sculpture flourished and produced treasures such as the Book of Kells, ornate jewellery and the many carved stone crosses that still dot the island today. A mission founded in 563 on Iona by the Irish monk Saint Columba began a tradition of Irish missionary work that spread Christianity and learning to Scotland, England and the Frankish Empire on Continental Europe after the fall of Rome. These missions continued until the late Middle Ages, establishing monasteries and centres of learning, producing scholars such as Sedulius Scottus and Johannes Eriugena and exerting much influence in Europe.
From the 9th century, waves of Viking raiders plundered Irish monasteries and towns. These raids added to a pattern of raiding and endemic warfare that was already deep-seated in Ireland. The Vikings also were involved in establishing most of the major coastal settlements in Ireland: Dublin, Limerick, Cork, Wexford, Waterford, and also Carlingford, Strangford, Annagassan, Arklow, Youghal, Lough Foyle and Lough Ree.
Norman and English invasions
On May 1, 1169, an expedition of Cambro-Norman knights with an army of about six hundred landed at Bannow Strand in present-day County Wexford. It was led by Richard de Clare, called Strongbow due to his prowess as an archer. The invasion, which coincided with a period of renewed Norman expansion, was at the invitation of Dermot Mac Murrough, the king of Leinster.
In 1166, Mac Murrough had fled to Anjou, France following a war involving Tighearnán Ua Ruairc, of Breifne, and sought the assistance of the Angevin king, Henry II, in recapturing his kingdom. In 1171, Henry arrived in Ireland in order to review the general progress of the expedition. He wanted to re-exert royal authority over the invasion which was expanding beyond his control. Henry successfully re-imposed his authority over Strongbow and the Cambro-Norman warlords and persuaded many of the Irish kings to accept him as their overlord, an arrangement confirmed in the 1175 Treaty of Windsor.
The invasion was legitimised by the provisions of the Papal Bull Laudabiliter, issued by Adrian IV in 1155. The bull encouraged Henry to take control in Ireland in order to oversee the financial and administrative reorganisation of the Irish Church and its integration into the Roman Church system. Some restructuring had already begun at the ecclesiastical level following the Synod of Kells in 1152. There has been significant controversy regarding authenticity of Laudabiliter, and there is no general agreement as to whether the bull was genuine or a forgery.
In 1172, the new pope, Alexander III, further encouraged Henry to advance the integration of the Irish Church with Rome. Henry was authorised to impose a tithe of one penny per hearth as an annual contribution. This church levy, called Peter's Pence, is still extant in Ireland as a voluntary donation. In turn, Henry accepted the title of Lord of Ireland which Henry conferred on his younger son, John Lackland, in 1185. This defined the Irish state as the Lordship of Ireland. When Henry's successor died unexpectedly in 1199, John inherited the crown of England and retained the Lordship of Ireland.
Over the century that followed, Norman feudal law gradually replaced the Gaelic Brehon Law so that by the late 13th century the Norman-Irish had established a feudal system throughout much of Ireland. Norman settlements were characterised by the establishment of baronies, manors, towns and the seeds of the modern county system. A version of the Magna Carta (the Great Charter of Ireland), substituting Dublin for London and Irish Church for Church of England, was published in 1216 and the Parliament of Ireland was founded in 1297.
However, from the mid-14th century, after the Black Death, Norman settlements in Ireland went into a period of decline. The Norman rulers and the Gaelic Irish elites intermarried and the areas under Norman rule became Gaelicised. In some parts, a hybrid Hiberno-Norman culture emerged. In response, the Irish parliament passed the Statutes of Kilkenny in 1367. These were a set of laws designed to prevent the assimilation of the Normans into Irish society by requiring English subjects in Ireland to speak English, follow English customs and abide by English law. However, by the end of the 15th century central English authority in Ireland had all but disappeared and a renewed Irish culture and language, albeit with Norman influences, was dominant again. English Crown control remained relatively unshaken in an amorphous foothold around Dublin known as The Pale and under the provisions of Poynings' Law of 1494, the Irish Parliamentary legislation was subject to the approval of the English Parliament.
Kingdom of Ireland
The title of King of Ireland was re-created in 1542 by Henry VIII, then King of England, of the Tudor dynasty. English rule of law was reinforced and expanded in Ireland during the latter part of the 16th century leading to the Tudor conquest of Ireland. A near complete conquest was achieved by the turn of the 17th century, following the Nine Years' War and the Flight of the Earls. This control was further consolidated during the wars and conflicts of the 17th century, which witnessed English and Scottish colonisation in the Plantations of Ireland, the Wars of the Three Kingdoms and the Williamite War. Irish losses during the Wars of the three Kingdoms (which, in Ireland, included the Irish Confederacy and the Cromwellian conquest of Ireland) are estimated to include 20,000 battlefield casualties. 200,000 civilians are estimated to have died as a result of a combination of war-related famine, displacement, guerilla activity and pestilence over the duration of the war. A further 50,000 were sent to slavery in the West Indies. Some historians estimate that as much as half of the pre-war population of Ireland may have died as a result of the conflict.
The religious struggles of the 17th century left a deep sectarian division in Ireland. Religious allegiance now determined the perception in law of loyalty to the Irish King and Parliament. After the passing of the Test Act 1672, and with the victory of the forces of the dual monarchy of William and Mary over the Jacobites, Roman Catholics and nonconforming Protestant Dissenters were barred from sitting as members in the Irish Parliament. Under the emerging penal laws Irish Roman Catholics and Dissenters were increasingly deprived of various and sundry civil rights even to the ownership of hereditary property. Additional regressive punitive legislation followed 1703, 1709 and 1728. This completed a comprehensive systemic effort to materially disadvantage Roman Catholics and Protestant Dissenters, while enriching a new ruling class of Anglican conformists. The new Anglo-Irish ruling class became known as the Protestant Ascendancy.
An extraordinary climatic shock known as the "Great Frost" struck Ireland and the rest of Europe between December 1739 and September 1741, after a decade of relatively mild winters. The winters destroyed stored crops of potatoes and other staples and the poor summers severely damaged harvests. This resulted in the famine of 1740. An estimated 250,000 people (about one in eight of the population) died from the ensuing pestilence and disease. The Irish government halted export of corn and kept the army in quarters but did little more. Local gentry and charitable organisations provided relief but could do little to prevent the ensuing mortality.
In the aftermath of the famine, an increase in industrial production and a surge in trade brought a succession of construction booms. The population soared in the latter part of this century and the architectural legacy of Georgian Ireland was built. In 1782, Poynings' Law was repealed, giving Ireland legislative independence from Great Britain for the first time since 1495. The British government, however, still retained the right to nominate the government of Ireland without the consent of the Irish parliament.
In 1798, members of the Protestant Dissenter tradition (mainly Presbyterian) made common cause with Roman Catholics in a republican rebellion inspired and led by the Society of United Irishmen, with the aim of creating an independent Ireland. Despite assistance from France the rebellion was put down by British and Irish government and yeomanry forces. In 1800, the British and Irish parliaments both passed Acts of Union that, with effect from 1 January 1801, merged the Kingdom of Ireland and the Kingdom of Great Britain to create a United Kingdom of Great Britain and Ireland.
Union with Great Britain
The passage of the Act in the Irish Parliament was ultimately achieved with substantial majorities, having failed on the first attempt in 1799. According to contemporary documents and historical analysis, this was achieved through a considerable degree of bribery, with funding provided by the British Secret Service Office, and the awarding of peerages, places and honours to secure votes. Thus, Ireland became part of an extended United Kingdom, ruled directly by a united parliament at Westminster in London.
Aside from the development of the linen industry, Ireland was largely passed over by the industrial revolution, partly because it lacked coal and iron resources and partly because of the impact of the sudden union with the structurally superior economy of England, which saw Ireland as a source of agricultural produce and capital.
The Great Famine of the 1840s caused the deaths of one million Irish people and over a million more emigrated to escape it. By the end of the decade, half of all immigration to the United States was from Ireland. Mass emigration became deeply entrenched and the population continued to decline until the mid-20th century. Immediately prior to the famine the population was recorded as 8.2 million by the 1841 census. The population has never returned to this level since. The population continued to fall until 1961 and it was not until the 2006 census that the last county of Ireland (County Leitrim) to record a rise in population since 1841 did so.
The 19th and early 20th centuries saw the rise of modern Irish nationalism, primarily among the Roman Catholic population. The pre-eminent Irish political figure after the Union was Daniel O'Connell. He was elected as Member of Parliament for Ennis in a surprise result and despite being unable to take his seat as a Roman Catholic. O'Connell spearheaded a vigorous campaign that was taken up by the Prime Minister, the Irish-born soldier and statesman, the Duke of Wellington. Steering the Catholic Relief Bill through Parliament, aided by future prime minister Robert Peel, Wellington prevailed upon a reluctant George IV to sign the Bill and proclaim it into law. George's father had opposed the plan of the earlier Prime Minister, Pitt the Younger, to introduce such a bill following the Union of 1801, fearing Catholic Emancipation to be in conflict with the Act of Settlement 1701.
A subsequent campaign, led by O'Connell, for the repeal of the Act of Union failed. Later in the century, Charles Stewart Parnell and others campaigned for autonomy within the Union, or "Home Rule". Unionists, especially those located in Ulster, were strongly opposed to Home Rule, which they thought would be dominated by Catholic interests. After several attempts to pass a Home Rule bill through parliament, it looked certain that one would finally pass in 1914. To prevent this from happening, the Ulster Volunteers were formed in 1913 under the leadership of Edward Carson.
Their formation was followed in 1914 by the establishment of the Irish Volunteers, whose aim was to ensure that the Home Rule Bill was passed. The Act was passed but with the "temporary" exclusion of the six counties of Ulster that would become Northern Ireland. Before it could be implemented, however, the Act was suspended for the duration of the First World War. The Irish Volunteers split into two groups. The majority, approximately 175,000 in number, under John Redmond, took the name National Volunteers and supported Irish involvement in the war. A minority, approximately 13,000, retained the Irish Volunteers name, and opposed Ireland's involvement in the war.
The failed Easter Rising of 1916 was carried out by the latter group in alliance with a smaller socialist militia, the Irish Citizen Army. The British response, executing fifteen leaders of the Rising over a period of ten days and imprisoning or interning more than a thousand people, turned the mood of the country in favour of the rebels. The pro-independence republican party, Sinn Féin, received overwhelming endorsement in the general election of 1918, and in 1919 proclaimed an Irish Republic, setting up its own parliament (Dáil Éireann) and government. Simultaneously the Volunteers, which became known as the Irish Republican Army (IRA), launched a three-year guerilla war, which ended in a truce in July 1921 (although violence continued until June 1922, mostly in Northern Ireland).
In December 1921, the Anglo-Irish Treaty was concluded between the British Government and representatives of the Second Dáil. It gave Ireland complete independence in its home affairs and practical independence for foreign policy, but an opt-out clause allowed Northern Ireland to remain within the United Kingdom, which it immediately exercised as expected. Additionally, an oath of allegiance to the King was to be taken. Disagreements over these provisions led to a split in the nationalist movement and a subsequent civil war between the new government of the Irish Free State and those opposed to the treaty, led by Éamon de Valera. The civil war officially ended in May 1923 when de Valera issued a cease-fire order.
During its first decade the newly formed Irish Free State was governed by the victors of the civil war. When de Valera achieved power, he took advantage of the Statute of Westminster and political circumstances to build upon inroads to greater sovereignty made by the previous government. The oath was abolished and in 1937 a new constitution was adopted. This completed a process of gradual separation from the British Empire that governments had pursued since independence. However, it was not until 1949 that the state was declared, officially, to be the Republic of Ireland.
The state was neutral during World War II, but offered clandestine assistance to the Allies, particularly in the potential defence of Northern Ireland. Despite being neutral, approximately 50,000 volunteers from independent Ireland joined the British forces during the war, four being awarded Victoria Crosses.
German Intelligence was also active in Ireland, with both the Abwehr ([ˈapveːɐ̯], German for Defence; the German military intelligence service) and the SD (the Sicherheitsdienst, English: Security Service, the intelligence service of the SS) sending agents there. German intelligence operations effectively ended in September 1941 when police made arrests on the basis of surveillance carried out on the key diplomatic legations in Ireland, including that of the United States. To the authorities counterintelligence was a fundamental line of defence. With a regular army of only slightly over seven thousand men at the start of the war, and with limited supplies of modern weapons, the state would have had great difficulty in defending itself from invasion from either side of the conflict.
Large-scale emigration marked the 1950s and 1980s, but beginning in 1987 the economy improved, and the 1990s saw the beginning of substantial economic growth. This period of growth became known as the Celtic Tiger. The Republic's real GDP grew by an average of 9.6% per annum between 1995 and 1999, in which year the Republic joined the euro. In 2000 Ireland was the sixth-richest country in the world in terms of GDP per capita. Social changes followed quickly on the heels of economic prosperity, ranging from the 'modernisation' of the annual parade in Dublin to mark the principal national holiday of Saint Patrick's Day (17 March), to the decline in authority of the Catholic Church. The financial crisis of 2008–2010 dramatically ended this period of boom. GDP fell by 3% in 2008 and by 7.1% in 2009, the worst year since records began (although earnings by foreign-owned businesses continued to grow). The state has since experienced deep recession, with unemployment, which doubled during 2009, remaining above 14% in 2012.
Northern Ireland was created as a division of the United Kingdom by the Government of Ireland Act 1920 and until 1972 it was a self-governing jurisdiction within the United Kingdom with its own parliament and prime minister. Northern Ireland, as part of the United Kingdom, was not neutral during the Second World War and Belfast suffered four bombing raids in 1941. Conscription was not extended to Northern Ireland and roughly an equal number volunteered from Northern Ireland as volunteered from the south. One, James Joseph Magennis, received the Victoria Cross for valour.
Although Northern Ireland was largely spared the strife of the civil war, in decades that followed partition there were sporadic episodes of inter-communal violence. Nationalists, mainly Roman Catholic, wanted to unite Ireland as an independent republic, whereas unionists, mainly Protestant, wanted Northern Ireland to remain in the United Kingdom. The Protestant and Catholic communities in Northern Ireland voted largely along sectarian lines, meaning that the Government of Northern Ireland (elected by "first-past-the-post" from 1929) was controlled by the Ulster Unionist Party. Over time, the minority Catholic community felt increasingly alienated with further disaffection fueled by practices such as gerrymandering and discrimination in housing and employment.
In the late 1960s, nationalist grievances were aired publicly in mass civil rights protests, which were often confronted by loyalist counter-protests. The government's reaction to confrontations was seen to be one-sided and heavy-handed in favour of unionists. Law and order broke down as unrest and inter-communal violence increased. The Northern Ireland government requested the British Army to aid the police, who were exhausted after several nights of serious rioting. In 1969, the paramilitary Provisional IRA, which favoured the creation of a united Ireland, emerged from a split in the Irish Republican Army and began a campaign against what it called the "British occupation of the six counties".
Other groups, on both the unionist side and the nationalist side, participated in violence and a period known as the Troubles began. Over 3,600 deaths resulted over the subsequent three decades of conflict. Owing to the civil unrest during the Troubles, the British government suspended home rule in 1972 and imposed direct rule. There were several unsuccessful attempts to end the Troubles politically, such as the Sunningdale Agreement of 1973. In 1998, following a ceasefire by the Provisional IRA and multi-party talks, the Good Friday Agreement was concluded as a treaty between the British and Irish governments, annexing the text agreed in the multi-party talks. The substance of the Agreement (formally referred to as the Belfast Agreement) was later endorsed by referendums in both parts of Ireland. The Agreement restored self-government to Northern Ireland on the basis of power-sharing in a regional Executive drawn from the major parties in a new Northern Ireland Assembly, with entrenched protections for the two main communities. The Executive is jointly headed by a First Minister and deputy First Minister drawn from the unionist and nationalist parties. Violence had decreased greatly after the Provisional IRA and loyalist ceasefires in 1994 and in 2005 the Provisional IRA announced the end of its armed campaign and an independent commission supervised its disarmament and that of other nationalist and unionist paramilitary organisations. The Assembly and power-sharing Executive were suspended several times but were restored again in 2007. In that year the British government officially ended its military support of the police in Northern Ireland (Operation Banner) and began withdrawing troops. On Wednesday, 27 June 2012, Northern Ireland's deputy first minister and former IRA commander, Martin McGuinness, shook hands with Queen Elizabeth II in Belfast, a handshake symbolizing reconciliation between the two nations.
Since 1922, Ireland has been partitioned between two political entities:
- The Republic of Ireland, formed as the Irish Free State on 6 December 1922, a sovereign state that covers five-sixths of the island. Its capital is Dublin.
- Northern Ireland, established on 3 May 1921, a part of the United Kingdom that covers the remaining portion of the island. Its capital is Belfast, with the capital of the United Kingdom being at London, England.
The North/South Ministerial Council, established under the 1998 Good Friday Agreement, is an institution through which ministers from the Government of Ireland and the Northern Ireland Executive agree all-island policies. At least six of these policy areas must have an associated all-island "implementation bodies" and at least six others must be implemented separately in each jurisdiction. For example, food safety is managed on an all-island basis by the Food Safety Promotion Board and Waterways Ireland is responsible for the maintenance and development of certain inland waterways on the island of Ireland. On the other hand, the two jurisdictions have common health and transport policies but these are implemented separately by already-existing bodies in each jurisdiction.
The current six areas for co-operations, implemented separately, are:
- Tourism, including Tourism Ireland
The current six all-island implementation bodies are:
- Waterways Ireland
- Food Safety Promotion Board
- Special European Union Programmes Body
- The North/South Language Body
- Foyle, Carlingford and Irish Lights Commission
Further development of the role and function of the Council are possible "with the specific endorsement of the Northern Ireland Assembly and Oireachtas, subject to the extent of the competences and responsibility of the two Administrations."
The North/South Ministerial Council and the Northern Ireland Assembly are defined in the Good Friday Agreement as being "mutually inter-dependent, and that one cannot successfully function without the other." Participation in the Council is a requisite for the operation of the Northern Ireland Assembly and participation in the Northern Ireland Executive. When devolution in Northern Ireland is suspended, the powers of the Northern Ireland Executive revert to the British–Irish Intergovernmental Conference.
The British–Irish Intergovernmental Conference provides for co-operation between the Government of Ireland and the Government of the United Kingdom on all matter of mutual interest, especially Northern Ireland. In light of Ireland's particular interest in the governance of Northern Ireland, "regular and frequent" meetings co-chaired by the Irish Minister for Foreign Affairs and the UK Secretary of State for Northern Ireland, dealing with non-devolved matters to do with Northern Ireland and non-devolved all-Ireland issues, are required to take place under the establishing treaty.
There is no joint parliamentary forum for the island of Ireland, like there is between the UK and Ireland as a whole. However, under the Good Friday Agreement, the Oireachtas and Northern Ireland Assembly are asked to consider developing one. The Agreement also contains a suggestion for the creation of a consultative forum composed of members of civil society from Northern Ireland and the Republic of Ireland. Under the 2007, St. Andrew's Agreement, the Northern Ireland Executive agreed to support the establishment of a North/South Consultative Forum and to encourage parties in the Northern Ireland Assembly to support the creation of a North/South parliamentary forum.
Three major political parties, Sinn Féin, the Irish Green Party and, most recently, Fianna Fáil, and several smaller parties are organised on an all-island basis. However, only Sinn Féin and the Greens have contested elections and have held legislative seats in both jurisdictions. The two jurisdictions share transport, telecommunications, energy and water systems. With a few notable exceptions, the island is the main organisational unit for major religious, cultural and sporting organisations.
Single energy market
Despite the two jurisdictions using two distinct currencies (the Euro and Pound Sterling), a growing amount of commercial activity is carried out on an all-island basis. This has been facilitated by the two jurisdictions' shared membership of the European Union, and there have been calls from members of the business community and policymakers for the creation of an "all-island economy" to take advantage of economies of scale and boost competitiveness. One area in which the island already operates as a single market is electricity and there are plans for the creation of an all-island gas market.
For much of their existence electricity networks in the Republic of Ireland and Northern Ireland were entirely separate. Both networks were designed and constructed independently post partition. However, as a result of changes over recent years they are now connected with three interlinks and also connected through Great Britain to mainland Europe. The situation in Northern Ireland is complicated by the issue of private companies not supplying Northern Ireland Electricity (NIE) with enough power. In the Republic of Ireland, the ESB has failed to modernise its power stations and the availability of power plants has recently averaged only 66%, one of the worst such rates in Western Europe. EirGrid is building a HVDC transmission line between Ireland and Great Britain with a capacity of 500 MW, about 10% of Ireland's peak demand.
As with electricity, the natural gas distribution network is also now all-island, with a pipeline linking Gormanston, County Meath, and Ballyclare, County Antrim. Most of Ireland's gas comes through interconnectors between Twynholm in Scotland and Ballylumford, County Antrim and Loughshinny, County Dublin. A decreasing supply is coming from the Kinsale gas field off the County Cork coast and the Corrib Gas Field off the coast of County Mayo has yet to come on-line. The County Mayo field is facing some localised opposition over a controversial decision to refine the gas onshore.
There have been recent efforts in Ireland to use renewable energy such as wind power. Large wind farms are being constructed in coastal counties such as Cork, Donegal, Mayo and Antrim. The construction of wind farms has in some cases been delayed by opposition from local communities, some of whom consider the wind turbines to be unsightly. The Republic of Ireland is also hindered by an ageing network that was not designed to handle the varying availability of power that comes from wind farms. The ESB's Turlough Hill facility is the only power-storage facility in the state.
The island of Ireland is located in the north-west of Europe, between latitudes 51° and 56° N, and longitudes 11° and 5° W. It is separated from the neighbouring island of Great Britain by the Irish Sea and the North Channel, which has a width of 23 kilometres (14 mi) at its narrowest point. To the west is the northern Atlantic Ocean and to the south is the Celtic Sea, which lies between Ireland and Brittany, in France. Ireland and Great Britain, together with nearby islands, are known collectively as the British Isles. As the term British Isles is controversial in relation to Ireland, the alternate term Britain and Ireland is often used as a neutral term for the islands.
A ring of coastal mountains surround low plains at the centre of the island. The highest of these is Carrauntoohil (Irish: Corrán Tuathail) in County Kerry, which rises to 1,038 m (3,406 ft) above sea level. The most arable land lies in the province of Leinster. Western areas can be mountainous and rocky with green panoramic vistas. The River Shannon, the island's longest river at 386 km (240 mi) long, rises in County Cavan in the north west and flows 113 kilometres (70 mi) to Limerick city in the mid west.
The island's lush vegetation, a product of its mild climate and frequent rainfall, earns it the sobriquet the Emerald Isle. Overall, Ireland has a mild but changeable oceanic climate with few extremes. The climate is typically insular and is temperate avoiding the extremes in temperature of many other areas in the world at similar latitudes. This is a result of the moderating moist winds which ordinarily prevail from the South-Western Atlantic.
Precipitation falls throughout the year but is light overall, particularly in the east. The west tends to be wetter on average and prone to Atlantic storms, especially in the late autumn and winter months. These occasionally bring destructive winds and higher total rainfall to these areas, as well as sometimes snow and hail. The regions of north County Galway and east County Mayo have the highest incidents of recorded lightning annually for the island, with lightening occurring approximately five to ten days per year in these areas.Munster, in the south, records the least snow whereas Ulster, in the north, records the most.
Inland areas are warmer in summer and colder in winter. Usually around 40 days of the year are below freezing 0 °C (32 °F) at inland weather stations, compared to 10 days at coastal stations. Ireland is sometimes affected by heat waves, most recently in 1995, 2003 and 2006. In common with the rest of Europe, Ireland experienced unusually cold weather during the winter of 2009/10. Temperatures fell as low as −17.2 °C (1 °F) in County Mayo on December 20 and up to a metre (3 ft) of snow in mountainous areas.
The island consists of varied geological provinces. In the far west, around County Galway and County Donegal, is a medium to high grade metamorphic and igneous complex of Caledonide affinity, similar to the Scottish Highlands. Across southeast Ulster and extending southwest to Longford and south to Navan is a province of Ordovician and Silurian rocks, with similarities to the Southern Uplands province of Scotland. Further south, along the County Wexford coastline, is an area of granite intrusives into more Ordovician and Silurian rocks, like that found in Wales. In the southwest, around Bantry Bay and the mountains of Macgillicuddy's Reeks, is an area of substantially deformed, but only lightly metamorphosed, Devonian-aged rocks. This partial ring of "hard rock" geology is covered by a blanket of Carboniferous limestone over the centre of the country, giving rise to a comparatively fertile and lush landscape. The west-coast district of the Burren around Lisdoonvarna has well-developed karst features. Significant stratiform lead-zinc mineralisation is found in the limestones around Silvermines and Tynagh.
Hydrocarbon exploration is ongoing following the first major find at the Kinsale Head gas field off Cork in the mid-1970s. More recently, in 1999, economically significant finds of natural gas were made in the Corrib Gas Field off the County Mayo coast. This has increased activity off the west coast in parallel with the "West of Shetland" step-out development from the North Sea hydrocarbon province. The Helvick oil field, estimated to contain over 28 million barrels (4,500,000 m3) of oil, is another recent discovery.
Places of interest
There are three World Heritage Sites on the island: the Brú na Boinne, Skellig Michael and the Giant's Causeway. A number of other places are on the tentative list, for example the Burren, the Ceide Fields and Mount Stewart.
Some of the most visited sites in Ireland include Bunratty Castle, the Rock of Cashel, the Cliffs of Moher, Holy Cross Abbey and Blarney Castle. Historically important monastic sites include Glendalough and Clonmacnoise, which are maintained as national monuments in the Republic of Ireland.
Dublin is the most heavily touristed region and home to several of the most popular attractions such as the Guinness Storehouse and Book of Kells. The west and south west, which includes the Lakes of Killarney and the Dingle peninsula in County Kerry and Connemara and the Aran Islands in County Galway, are also popular tourist destinations.Achill Island lies off the coast of County Mayo and is Ireland's largest island. It is a popular tourist destination for surfing and contains 5 Blue Flag beaches and Croaghaun one of the worlds highest sea cliffs. Stately homes, built during the 17th, 18th and 19th centuries in Palladian, Neoclassical and neo-Gothic styles, such as, Castle Ward, Castletown House, Bantry House, are also of interest to tourists. Some have been converted into hotels, such as Ashford Castle, Castle Leslie and Dromoland Castle.
Flora and fauna
As Ireland was isolated from mainland Europe by rising sea levels after the ice age, it has less diverse animal and plant species than either Great Britain or mainland Europe. There are 55 mammal species in Ireland and of them only 26 land mammal species are considered native to Ireland. Some species, such as, the red fox, hedgehog and badger, are very common, whereas others, like the Irish hare, red deer and pine marten are less so. Aquatic wildlife, such as species of sea turtle, shark, seal, whale, and dolphin, are common off the coast. About 400 species of birds have been recorded in Ireland. Many of these are migratory, including the Barn Swallow. Most of Ireland's bird species come from Iceland, Greenland and Africa.
Several different habitat types are found in Ireland, including farmland, open woodland, temperate broadleaf and mixed forests, conifer plantations, peat bogs and a variety of coastal habitats. However, agriculture drives current land use patterns in Ireland, limiting natural habitat preserves, particularly for larger wild mammals with greater territorial needs. With no top predator in Ireland, populations of animals, such as semi-wild deer, that cannot be controlled by smaller predators, such as the fox, are controlled by annual culling.
There are no snakes in Ireland and only one reptile (the common lizard) is native to the island. Extinct species include the Irish elk, the great auk and the wolf. Some previously extinct birds, such as, the Golden Eagle, have recently been reintroduced after decades of extirpation.
Until medieval times Ireland was heavily forested with oak, pine and birch. Forests today cover about 12.6% of Ireland, of which 4,450 km² or one million acres is owned by Coillte, the Republic's forestry service. The Republic lies in 42nd place (out of 55) in a list of the most forested countries in Europe. Much of the land is now covered with pasture and there are many species of wild-flower. Gorse (Ulex europaeus), a wild furze, is commonly found growing in the uplands and ferns are plentiful in the more moist regions, especially in the western parts. It is home to hundreds of plant species, some of them unique to the island, and has been "invaded" by some grasses, such as Spartina anglica.
The algal and seaweed flora is that of the cold-temperate variety. The total number of species is 574 and is distributed as follows:
- 264 Rhodophyta (red algae)
- 152 Phaeophyceae (brown algae including kelps)
- 114 Chloropyta (green algae)
- 31 Cyanophyta (Blue-green algae)
Rarer species include:
- Itonoa marginifera (J.Agardh) Masuda & Guiry
- Schmitzia hiscockiana Maggs & Guiry
- Gelidiella calcicola Maggs & Guiry
- Gelidium maggsiae Rico & Guiry
- Halymenia latifolia P.L.Crouan & H.M.Crouan ex Kützing.
The island has been invaded by some algae, some of which are now well established. For example:
- Asparagopsis armara Harvey, which originated in Australia and was first recorded by M. De Valera in 1939
- Colpomenia peregrina Sauvageau, which is now locally abundant and first recorded in the 1930s
- Sargassum muticum (Yendo) Fensholt, now well established in a number of localities on the south, west, and north-east coasts
- Codium fragile ssp. fragile (formerly reported as ssp. tomentosum), now well established.
Codium fragile ssp. atlanticum has recently been established to be native, although for many years it was regarded as an alien species.
Because of its mild climate, many species, including sub-tropical species such as palm trees, are grown in Ireland. Phytogeographically, Ireland belongs to the Atlantic European province of the Circumboreal Region within the Boreal Kingdom. The island itself can be subdivided into two ecoregions: the Celtic broadleaf forests and North Atlantic moist mixed forests.
Impact of agriculture
The long history of agricultural production, coupled with modern intensive agricultural methods such as pesticide and fertiliser use and runoff from contaminants into streams, rivers and lakes, impact the natural fresh-water ecosystems and have placed pressure on biodiversity in Ireland.
A land of green fields for crop cultivation and cattle rearing limits the space available for the establishment of native wild species. Hedgerows, however, traditionally used for maintaining and demarcating land boundaries, act as a refuge for native wild flora. This ecosystem stretches across the countryside and acts as a network of connections to preserve remnants of the ecosystem that once covered the island. Subsidies under the Common Agricultural Policy, which supported agricultural practices that preserved hedgerow environments, are undergoing reforms. The Common Agricultural Policy had in the past subsidised potentially destructive agricultural practices, for example by emphasising production without placing limits on indiscriminate use of fertilisers and pesticides; but recent reforms have gradually decoupled subsidies from production levels and introduced environmental and other requirements.
Forest covers about 12.6% of the country, most of it designated for commercial production. Forested areas typically consist of monoculture plantations of non-native species, which may result in habitats that are not suitable for supporting native species of invertebrates. Remnants of native forest can be found scattered around the island, in particular in the Killarney National Park. Natural areas require fencing to prevent over-grazing by deer and sheep that roam over uncultivated areas. Grazing in this manner is one of the main factors preventing the natural regeneration of forests across many regions of the country.
People have lived in Ireland for over 9,000 years, although only a limited amount is known about the palaeolithic, neolithic and Bronze Age inhabitants of the island. Early historical and genealogical records note the existence of dozens of different peoples that may or may not be mythological, for example the Cruithne, Attacotti, Conmaicne, Eóganachta, Érainn, and Soghain, to name but a few. Over the past 1000 years or so, Vikings, Normans, Scots and English have all added to the Gaelic population and have had significant influences on Irish Culture.
Ireland's largest religious group is Christianity. The largest denomination is Roman Catholicism representing over 73% for the island (and about 87% of the Republic of Ireland). Most of the rest of the population adhere to one of the various Protestant denominations (about 53% of Northern Ireland). The largest is the Anglican Church of Ireland. The Muslim community is growing in Ireland, mostly through increased immigration. The island has a small Jewish community. About 4% of the Republic's population and about 14% of the Northern Ireland population describe themselves as of no religion. In a 2010 survey conducted on behalf of the Irish Times, 32% of respondents said they went to a religious service more than once a week.
The population of Ireland rose rapidly from the 16th century until the mid-19th century, but a devastating famine in the 1840s caused one million deaths and forced over one million more to emigrate in its immediate wake. Over the following century the population was reduced by over half, at a time when the general trend in European countries was for populations to rise by an average of three-fold.
Divisions and settlements
Traditionally, Ireland is subdivided into four provinces: Connacht (west), Leinster (east), Munster (south), and Ulster (north). In a system that developed between the 13th and 17th centuries, Ireland has 32 traditional counties. Twenty-six of these counties are in the Republic of Ireland and six are in Northern Ireland. The six counties that constitute Northern Ireland are all in the province of Ulster (which has nine counties in total). As such, Ulster is often used as a synonym for Northern Ireland, although the two are not coterminous.
In the Republic of Ireland, counties form the basis of the system of local government. Counties Dublin, Cork, Limerick, Galway, Waterford and Tipperary have been broken up into smaller administrative areas. However, they are still treated as counties for cultural and some official purposes, for example postal addresses and by the Ordnance Survey Ireland. Counties in Northern Ireland are no longer used for local governmental purposes, but, as in the Republic, their traditional boundaries are still used for informal purposes such as sports leagues and in cultural or tourism contexts.
City status in Ireland is decided by legislative or royal charter. Dublin, with over 1 million residents in the Greater Dublin Area, is the largest city on the island. Belfast, with 579,726 residents, is the largest city in Northern Ireland. City status does not directly equate with population size. For example, Armagh, with 14,590 is the seat of the Church of Ireland and the Roman Catholic Primate of All Ireland and was re-granted city status by Queen Elizabeth II in 1994 (having lost that status in local government reforms of 1840). In the Republic of Ireland, Kilkenny, seat of the Butler dynasty, while no longer a city for administrative purposes (since the 2001 Local Government Act), is entitled by law to continue to use the description.
The population of Ireland collapsed dramatically during the second half of the 19th century. A population of over 8 million in 1841 was reduced to slightly more than 4 million by 1921. In part, the fall in population was due to death from the Great Famine of 1845 to 1852, which took about 1 million lives. However, by far the greater cause of population decline was the dire economic state of the country which led to an entrenched culture of emigration lasting until the 21st century.
Emigration from Ireland in the 19th century contributed to the populations of England, the United States, Canada and Australia where today a large Irish diaspora lives. Today 4.3 million Canadians, or 14% of her population, are of Irish descent. A total of 36 million Americans claim Irish ancestry – more than 12% of the total population and 20% of the white population.Massachusetts is the most Irish of US states with 23.8% of the population claiming Irish ancestry. The pattern of immigration over this period particularly devastated the western and southern seaboards. Prior to the Great Famine, the provinces of Connacht, Munster and Leinster were more or less evenly populated whereas Ulster was far less densely populated than the other three. Today, Ulster and Leinster, and in particular Dublin, have a far greater population density than Munster and Connacht.
With growing prosperity since the last decade of the 20th century, Ireland became a destination for immigrants. Since the European Union expanded to include Poland in 2004, Polish people have made up the largest number of immigrants (over 150,000) from Central Europe. There has also been significant immigration from Lithuania, the Czech Republic and Latvia.
The Republic of Ireland in particular has seen large-scale immigration. The 2006 census recorded that 420,000 foreign nationals, or about 10% of the population, lived in the Republic of Ireland.Chinese and Nigerians, along with people from other African countries, have accounted for a large proportion of the non–European Union migrants to Ireland. Up to 50,000 eastern European migrant workers may have left Ireland since the end of 2008.
Two main languages are spoken in Ireland: Irish and English. Both languages have widely contributed to literature. Irish, now a minority but official language of the Republic of Ireland, was the vernacular of the Irish people for over two thousand years and was probably introduced by some sort of proto-Gaelic migration during the Iron age, possibly earlier. It began to be written down after Christianisation in the 5th century and spread to Scotland and the Isle of Man where it evolved into the Scottish Gaelic and Manx languages respectively. It has a vast treasure of written texts from many centuries, and is divided by linguists into Old Irish from the 6th to 10th century, Middle Irish from the 10th to 13th century, Early Modern Irish until the 17th century, and the Modern Irish spoken today. It remained the dominant language of Ireland for most of those periods, having influences from Latin, Old Norse, French and English. It declined under British rule but remained the majority tongue until the early 19th century, and since then has been a minority language, although revival efforts are continuing in both the Republic of Ireland and Northern Ireland. However, Gaeltacht or Irish-speaking areas are still seeing a decline in the language. Irish language is a compulsory subject in the state education system in the Republic, and the Gaelscoil movement has seen many Irish medium schools established in both jurisdictions.
English was first introduced to Ireland in the Norman invasion. It was spoken by a few peasants and merchants brought over from England, and was largely replaced by Irish before the Tudor Conquest of Ireland. It was introduced as the official language with the Tudor and Cromwellian conquests. The Ulster plantations gave it a permanent foothold in Ulster, and it remained the official and upper-class language elsewhere, the Irish-speaking chieftains and nobility having been deposed. Language shift during the 19th century replaced Irish with English as the first language for a vast majority of the population. Less than 10% of the population of the Republic of Ireland today speak Irish regularly outside of the education system and 38% of those over 15 years are classified as "Irish speakers." In Northern Ireland, English is the de facto official language, but official recognition is afforded to Irish, including specific protective measures under Part III of the European Charter for Regional or Minority Languages. A lesser status (including recognition under Part II of the Charter) is given to Ulster Scots dialects, which are also spoken by some in the Republic of Ireland. In recent decades, with the increase in immigration, many more languages have been introduced, particularly deriving from Asia and Eastern Europe.
Ireland's culture comprises elements of the culture of ancient immigration and influences (such as Gaelic culture) and more recent Anglicisation and Americanisation as well as participation in a broader European culture. In broad terms, Ireland is regarded as one of the Celtic nations of Europe, which also includes Scotland, Wales, Cornwall, Isle of Mann and Brittany. This combination of cultural influences is visible in the intricate designs termed Irish interlace or Celtic knotwork. These can be seen in the ornamentation of medieval religious and secular works. The style is still popular today in jewellery and graphic art, as is the distinctive style of traditional Irish music and dance, and has become indicative of modern "Celtic" culture in general.
Religion has played a significant role in the cultural life of the island since ancient times (and since the 17th century plantations, has been the focus of political identity and divisions on the island). Ireland's pre-Christian heritage fused with the Celtic Church following the missions of Saint Patrick in the 5th century. The Hiberno-Scottish missions, begun by the Irish monk Saint Columba, spread the Irish vision of Christianity to pagan England and the Frankish Empire. These missions brought written language to an illiterate population of Europe during the Dark Ages that followed the fall of Rome, earning Ireland the sobriquet, "the island of saints and scholars". In more recent years, the Irish pubs have become outposts of Irish culture worldwide.
The Republic of Ireland's national theatre is the Abbey Theatre founded in 1904 and the national Irish-language theatre is An Taibhdhearc, established in 1928 in Galway. Playwrights such as Seán O'Casey, Brian Friel, Sebastian Barry, Conor McPherson and Billy Roche are internationally renowned.
There are a number of languages used in Ireland. Irish is the only language to have originated from within the island. Since the late 19th century, English has become the predominant first language having been a spoken language in Ireland since the Middle Ages. A large minority claim some ability to speak Irish today, although it is the first language only of a small percentage of the population. Under Constitution of Ireland, both languages have official status with Irish being the national and first official language. In Northern Ireland English is the dominant state language, whilst Irish and Ulster Scots are recognised minority languages.
Ireland has made a large contribution to world literature in all its branches, particularly in the English language. Poetry in Irish is the oldest vernacular poetry in Europe, with the earliest examples dating from the 6th century. In English, Jonathan Swift, still often called the foremost satirist in the English language, was wildly popular in his day for works such as Gulliver's Travels and A Modest Proposal and Oscar Wilde is known most for his often quoted witticisms.
In the 20th century, Ireland produced four winners of the Nobel Prize for Literature: George Bernard Shaw, William Butler Yeats, Samuel Beckett and Seamus Heaney. Although not a Nobel Prize winner, James Joyce is widely considered to be one of the most significant writers of the 20th century. Joyce's 1922 novel Ulysses is considered one of the most important works of Modernist literature and his life is celebrated annually on 16 June in Dublin as "Bloomsday". Modern Irish literature is often connected with its rural heritage through writers such as John McGahern and poets such as Seamus Heaney.
The Irish traditional music and dance has seen a recent surge in popularity, not least through the phenomenon of Riverdance, a theatrical performance of Irish traditional dancing. In the middle years of the 20th century, as Irish society was modernising, traditional music fell out of favour, especially in urban areas. During the 1960s, inspired by the American folk music movement, there was a revival of interest in Irish traditional music led by groups such as The Dubliners, The Chieftains, Emmet Spiceland, The Wolfe Tones, the Clancy Brothers, Sweeney's Men and individuals like Seán Ó Riada and Christy Moore.
Groups and musicians including Horslips, Van Morrison and Thin Lizzy incorporated elements of Irish traditional music into contemporary rock music and, during the 1970s and 1980s, the distinction between traditional and rock musicians became blurred, with many individuals regularly crossing over between these styles of playing. This trend can be seen more recently in the work of artists like Enya, The Saw Doctors, The Corrs, Sinéad O'Connor, Clannad, The Cranberries, Black 47 and The Pogues among others.
During the 1990s a sub-genre of folk metal emerged in Ireland that fused heavy metal music with Irish and Celtic music. The pioneers of this sub-genre were Cruachan, Primordial, and Waylander. Some contemporary music groups stick closer to a "traditional" sound, including Altan, Téada, Danú, Dervish, Lúnasa, and Solas. Others incorporate multiple cultures in a fusion of styles, such as Afro Celt Sound System and Kíla.
The earliest known Irish graphic art and sculpture are Neolithic carvings found at sites such as Newgrange and is traced through Bronze age artefacts and the religious carvings and illuminated manuscripts of the medieval period. During the course of the 19th and 20th centuries, a strong tradition of painting emerged, including such figures as John Butler Yeats, William Orpen, Jack Yeats and Louis le Brocquy. Contemporary Irish visual artists of note include Sean Scully, Kevin Abosch, and Alice Maher.
The Irish philosopher and theologian Johannes Scotus Eriugena was considered one of the leading intellectuals of his early Middle Ages. Sir Ernest Henry Shackleton, an Anglo-Irish explorer, was one of the principal figures of Antarctic exploration. He, along with his expedition, made the first ascent of Mount Erebus and the discovery of the approximate location of the South Magnetic Pole. Robert Boyle was a 17th-century natural philosopher, chemist, physicist, inventor and early gentleman scientist. He is largely regarded one of the founders of modern chemistry and is best known for the formulation of Boyle's law. 19th century physicist, John Tyndall, discovered the Tyndall effect, which explains why the sky is blue. Father Nicholas Joseph Callan, Professor of Natural Philosophy in Maynooth College, is best known for his invention of the induction coil, transformer and he discovered an early method of galvanisation in the 19th century.
Other notable Irish physicists include Ernest Walton, winner of the 1951 Nobel Prize in Physics. With Sir John Douglas Cockcroft, he was the first to split the nucleus of the atom by artificial means and made contributions to the development of a new theory of wave equation. William Thomson, or Lord Kelvin, is the person whom the absolute temperature unit, the Kelvin, is named after. Sir Joseph Larmor, a physicist and mathematician, made innovations in the understanding of electricity, dynamics, thermodynamics and the electron theory of matter. His most influential work was Aether and Matter, a book on theoretical physics published in 1900.
George Johnstone Stoney introduced the term electron in 1891. John Stewart Bell was the originator of Bell's Theorem and a paper concerning the discovery of the Bell-Jackiw-Adler anomaly and was nominated for a Nobel prize. Notable mathematicians include Sir William Rowan Hamilton, famous for work in classical mechanics and the invention of quaternions. Francis Ysidro Edgeworth's contribution of the Edgeworth Box remains influential in neo-classical microeconomic theory to this day; while Richard Cantillon inspired Adam Smith, among others. John B. Cosgrave was a specialist in number theory and discovered a 2000-digit prime number in 1999 and a record composite Fermat number in 2003. John Lighton Synge made progress in different fields of science, including mechanics and geometrical methods in general relativity. He had mathematician John Nash as one of his students.
Ireland has nine universities, seven in the Republic of Ireland and two in Northern Ireland, including Trinity College, Dublin and the University College Dublin, as well as numerous third-level colleges and institutes and a branch of the Open University, the Open University in Ireland.
