🇮🇪 Ireland

The Celts settled Ireland between roughly 600 and 150 B.C., laying the foundations of Gaelic culture.

His victory at Clontarf in 1014 finally ended the Norse invasions that had begun in the late 8th century.

Anglo-Norman invasions beginning in the 12th century brought castle-building, notably Dublin and Kilkenny Castles, and the planned walled trading town chartered under feudalism, and together with Cistercian church reform opened Ireland to sustained continental and later English and Scottish cultural influence. They also set off more than seven centuries of Anglo-Irish struggle marked by fierce rebellions and harsh repressions.

Gradual conquest and colonisation from the 16th century embedded English and Scottish institutions, landholding and culture across the island. It created the Protestant Ascendancy whose privileges shaped politics into the twentieth century.

From the union of the crowns the arms of Ireland appeared quartered on the royal coat of arms of the United Kingdom. The dynastic union tied Irish governance directly to the British monarchy.

Victory at the Boyne consolidated the Protestant settlement in Ireland. In its aftermath palladian and rococo architecture spread through country houses under continental influence and Ireland's first trained architects such as Edward Lovett Pearce.

From 1 January 1801 the whole island of Ireland was governed as part of the United Kingdom of Great Britain and Ireland. This arrangement lasted until 6 December 1922 and framed all subsequent Irish constitutional politics, from home rule agitation to revolution.

Successive failures of the potato crop from blight devastated the island: about one million people died of starvation and disease and up to 1.5 million emigrated, mostly to the United States, cutting a population of over eight million by a quarter to 30% within a decade. The famine set a pattern of emigration that produced continuous population decline until the 1960s, permanently reshaping Irish society, demography and its diaspora.

Starvation and emigration in the mid-19th century devastated the population, which continued to fall for more than a century before growing again from the 1960s. Ireland's high birthrate over the last 50 years has made it demographically one of the youngest populations in the EU.

From 1874, and particularly under Charles Stewart Parnell from 1880, the party combined agrarian agitation through the Irish Land League with parliamentary pressure for Home Rule. The Land League campaign won tenant protections in the Irish Land Acts, while two Home Rule bills failed to grant Ireland limited autonomy.

Unionism grew from the introduction of the first home rule bill in 1886, fed by fears of discrimination and loss of economic and social privilege should Irish Catholics gain political power. It was strongest in industrialised parts of Ulster, where Protestants held majorities in four counties, and under Edward Carson and James Craig it became militant, forming the Ulster Volunteers.

The Act transferred national and local affairs from landlord-dominated grand juries of the Protestant Ascendancy to elected 'grass-roots' bodies. It remains the founding statute of the present Irish system of local government, later given constitutional recognition by the Twentieth Amendment of 1999.

Removal of the Lords' veto meant a Home Rule bill could no longer be blocked indefinitely by the upper house. This made Irish self-government appear certain and precipitated the Ulster crisis of the following years.

The Bill passed parliament in May 1914 and received Royal Assent, but Asquith introduced an Amending Bill providing for temporary exclusion of Ulster for six years to avoid rebellion. Implementation was suspended until after the First World War, defusing the immediate threat of civil war but leaving the Irish question unresolved.

Redmond and the Irish National Volunteers supported the UK and its Allies in the hope of guaranteeing Home Rule after the war. Some 175,000 men joined the 10th and 16th (Irish) divisions of the New British Army, while unionists joined the 36th (Ulster) division.

The insurrection began on 24 April 1916 with the Proclamation of the Republic and a week of heavy fighting, mainly in Dublin, before the rebels surrendered. Fifteen prisoners, including Patrick Pearse and James Connolly, were court-martialled and executed under the Defence of the Realm Act; the executions, arrests and the 1918 Conscription Crisis turned Irish public opinion decisively against British rule.

Seventy-three of Ireland's 105 MPs elected were Sinn Féin members pledged to abstain from the British House of Commons. The result destroyed the Irish Parliamentary Party's mandate and provided the electoral basis for a separatist assembly.

A delegation under Ceann Comhairle Seán T. O'Kelly sought international recognition of the Irish Republic at the peace conference. It was not admitted, denying the new republic early diplomatic legitimacy.

The First Dáil assembled in Dublin, issued a declaration of independence and proclaimed an Irish Republic, restating the 1916 Proclamation with the added assertion that Ireland was no longer part of the United Kingdom. It created the institutional core of an alternative Irish state.

The guerrilla war between Irish republican forces and British forces was halted by truce in July 1921. The ceasefire opened the way to formal negotiations in London later that year.

Five Irish delegates led by Arthur Griffith, Robert Barton and Michael Collins negotiated with British representatives from 11 October to 6 December 1921, deciding at Hans Place on 5 December to recommend the treaty. The treaty granted dominion status rather than a republic, setting the terms of Irish sovereignty and the terms of the split to come.

The flag, originating with the mid-19th-century Young Ireland movement and popularised during the 1916 Easter Rising, was adopted by the Free State in 1922. It remains the sole flag and ensign of the state, joined by the anthem officially adopted in 1926.

The narrow vote on 7 January 1922 accepted dominion status and the oath to the British king. The margin exposed the fracture in the independence movement that led directly to civil war.

The IRA split into pro- and anti-treaty camps, with anti-treaty forces under Éamon de Valera rejecting the abolition of the 1919 Republic and the oath to the king, while Collins argued the treaty gave the freedom to achieve full freedom. The pro-treaty side built a National Army of tens of thousands, aided by British artillery, aircraft and ammunition, and defeated the Irregulars, who lacked command structure and public support.

Under the Anglo-Irish Treaty signed in December 1921, the entire island became a Dominion, Saorstát Éireann, a constitutional monarchy sharing a monarch with the United Kingdom, with a governor-general, bicameral parliament, an Executive Council and a President of the Executive Council. It gave Ireland its first self-governing state institutions, covering 26 of the 32 counties in practice, while the treaty's terms split the nationalist movement and triggered a civil war that lasted until 1923.

By address to the King, Northern Ireland requested that the powers of the Free State's parliament and government no longer extend to it, and rejoined the United Kingdom. Partition was thereby confirmed and became the central unresolved question of twentieth-century Irish politics.

The song, first published in English in 1912 and translated into Irish in 1923, was made the state anthem in 1926. The Irish-language version is the one commonly sung today.

Removal of the Crown's representative stripped away a principal symbol of dominion subordination. It cleared the ground for the new constitution adopted the following year.

Drafted under Éamon de Valera and approved by plebiscite in July 1937, Bunreacht na hÉireann came into force on 29 December 1937, replacing the 1922 Free State constitution, naming the state Éire, or Ireland, and establishing the office of president. Articles 2 and 3 claimed the whole island while confining jurisdiction to the former Free State area; the president exercised internal head-of-state functions, making the state effectively a republic though diplomats were still accredited to the king.

Neutrality asserted the state's independent sovereignty but cost it goodwill among the Allies and delayed its admission to the United Nations. More than 50,000 people from Ireland nonetheless took part in the war by enlisting in the British armed forces.

The Act came into force on 18 April 1949, terminating dominion status and declaring the description of the state to be the Republic of Ireland, though without renaming it in the Constitution. Declaring a republic then ended Commonwealth membership; the rule changed with the London Declaration of 28 April 1949, but Ireland did not reapply.

The declaration came ten days after Ireland's republican declaration had automatically ended its Commonwealth membership. Ireland chose not to reapply once the rules allowed republics to join, leaving it permanently outside the Commonwealth.

Membership had previously been denied because of Irish neutrality in the Second World War and its refusal to support the Allied cause. Accession involved a commitment to using force to deter aggression where the UN judged it necessary, and opened the way to Ireland's later peacekeeping role.

Contributions started with the Congo Crisis and continued in Cyprus, Lebanon and Bosnia and Herzegovina. By 1996 more than 40,000 Irish service personnel had served in international UN peacekeeping missions, giving a small force outsized international standing.

Application was driven by substantial economic linkages with the United Kingdom, which itself intended to join. Founding EC members were sceptical of Ireland's economic capacity, neutrality and protectionist policy, prompting Irish economists and politicians to accept that economic reform was necessary.

The French president's opposition to Britain's entry ended negotiations with all other candidate countries, including Ireland. Prospects only revived when Georges Pompidou dropped the objection in 1969.

Unresolved issues in the six northern counties that remained part of the UK broke out into years of sectarian violence beginning in the late 1960s.

The crisis was fuelled by the government's budget, abolition of the car tax, excessive borrowing and global instability including the 1979 oil crisis. It left a legacy of public indebtedness that dominated policy until reform began in 1989.

The Fifth Amendment, carried by referendum, removed the enumeration of named religious denominations from the Constitution. It was part of the process that left the state's constitution secular from 1973.

Following the 1972 Treaty of Accession and a referendum in which over 80 per cent of voters backed accession, Ireland became a member of the European Communities on 1 January 1973, alongside Denmark and the United Kingdom. Membership reshaped Irish trade and agricultural policy and reoriented the economy away from dependence on the United Kingdom, underpinning later growth; Ireland has since held the Presidency of the Council on six occasions, most recently in 2013.

The six-month presidency, running to the end of December 2026, gives Ireland responsibility for chairing EU Council meetings and setting the bloc's legislative agenda across member states.

The bill bans imports of goods from Israeli settlements in the occupied Palestinian territories and cleared the Seanad in mid-July 2026, after a late attempt to extend the ban to services was defeated. It was expected to be signed into law within weeks.

July 2026 was also the second-hottest July since 1900 and the third-hottest month of any kind in Irish history, prompting water restrictions at 13 supplies and a nationwide hosepipe ban.

The Defence (Amendment) Bill 2026 removes the requirement for United Nations Security Council approval before deploying more than 12 Defence Forces personnel overseas, leaving government and parliamentary approval as sufficient. Opposition parties said the change would erode military neutrality; the government denied this.

Consumption had already reached 23 per cent of national electricity in 2025, up from 21 per cent the previous year. The United Nations described Ireland's strain on grid capacity as a cautionary tale for other countries pursuing artificial-intelligence infrastructure.

The Residential Tenancies (Miscellaneous Provisions) Bill 2026 set a minimum tenancy of six years and restricted no-fault evictions. It followed Budget 2026 figures showing over 16,350 people recorded as homeless, a record high.

The Section 122 tariff rate on Irish exports fell from 20 per cent to 10 per cent on 24 February 2026. Pharmaceuticals, Ireland's largest export to the US, remained shielded under the separate EU-US framework agreement's tariff ceiling.

The storm struck on 27 January 2026, causing severe flooding in counties Wexford and Kilkenny and prompting emergency rescues of motorists. Local authorities were placed on full alert across Leinster amid the wettest spell in 85 years of records.

Connolly took office after the 2025 presidential election, in which restrictive nomination rules contributed to 12.9% spoilt votes. The result highlighted continuing debate over access to the presidential ballot.

The finance minister's budget, announced on 7 October 2025, prioritised capital investment over tax cuts, with €8.1 billion allocated to infrastructure and housing. It also raised core welfare rates by €10 a week and funded a Christmas bonus for 1.5 million recipients.

The independent TD defeated Fine Gael's Heather Humphreys, who took 29 per cent, in the 24 October 2025 election. Connolly was inaugurated as Ireland's 10th president on 11 November 2025.

The count was 8% higher than in 2016, with non-Irish nationals at 631,785, led by Poland, the UK, India, Romania and the Baltic states. Catholic identification fell from 84.2% in 2011 to 69.1%, marking rapid secularisation alongside the highest birth rate in the EU.

66.4 per cent supported repeal in the referendum held on 25 May 2018, removing the constitutional ban on abortion. Parliament subsequently passed legislation permitting abortion up to 12 weeks of pregnancy.

Ireland became one of the twelve Test-playing members of the International Cricket Council. The step followed rising domestic popularity after the team's performance at the 2007 Cricket World Cup.

Signature aligned Ireland with the disarmament bloc and reinforced its long-standing non-aligned diplomatic identity. It continued a tradition of Irish activism on nuclear non-proliferation.

Restructuring of Apple's Irish subsidiaries and the presence of firms such as Google, Microsoft and Facebook produced a GDP growth rate of 26.3% and GNP growth of 18.7%. The episode, named by Paul Krugman, exposed how far Irish national accounts had become dependent on multinational balance sheets.

62 per cent backed the constitutional amendment on 22 May 2015, making Ireland the first country to legalise same-sex marriage through a popular vote rather than legislation or a court ruling.

The state left its external assistance programme on 15 December 2013, regaining full control of its finances. Recovery followed, with unemployment falling from 8.6% in March 2016 to 4.4% by November 2022.

The field was assessed as holding up to 1.6 billion barrels, with 160 to 600 million recoverable, potentially covering Ireland's entire energy needs for up to 13 years. The Corrib gas field was also due on stream in 2013/14, offering partial relief from import dependence.

Some 3,000 MW of wind farms were built, partly for export, and the SEAI estimated 6.5% of 2011 energy needs came from renewables, with carbon emissions per house down 28% between 2005 and 2013. By 2021 Ireland was the 24th largest wind energy producer in the world and third per capita in 2020.

After the property bubble burst the economy officially left recession in 2010, driven by exports from US multinationals, growing 0.7% in 2011 and 0.9% in 2012. Unemployment nonetheless peaked at 15.1% in February 2012 and net emigration reached 120,100 between 2008 and 2013.

The rescue followed a 2008 state guarantee of the banking system and a property crash that drove the budget deficit above 30 per cent of GDP. Ireland exited the programme in December 2013.

Pharmaceutical and technology multinationals restructured through Ireland, and a 2017 study ranked the country as the fifth largest global Conduit OFC routing funds to tax havens. Foreign multinationals came to employ a quarter of the private sector workforce and pay 80% of corporate taxes, while EU proposals such as the 2018 Digital Sales Tax sought to curb such schemes.

By 2007 Ireland had the highest private sector debt in the OECD, with household debt at 190% of disposable income; when global capital markets withdrew support in the 2008 financial crisis, a deep property correction followed. The resulting banking crisis forced an EU-IMF bailout and left Ireland with among the highest public and private indebtedness in the EU-28 and OECD as late as 2017.

Ireland was the first country in the world to ban smoking in enclosed workplaces and public places. It was followed by a ban on in-store tobacco advertising and display in 2009 and plain cigarette packaging in 2015, though smoking rates remained around 15.4% in 2020.

US military personnel transited Shannon en route to the 2003 invasion of Iraq, as they had for the 2001 invasion of Afghanistan and the First Gulf War. The practice became a recurring test of the meaning of Irish neutrality.

The environmental levy on plastic shopping bags was the first such measure anywhere in the world. It established Ireland as an early mover in regulatory environmental policy, followed by lightbulb and tobacco measures later in the decade.

The amendment gave constitutional status to the local government system founded by the 1898 Act. Later statutes in 2001 and 2014 restructured it into thirty-one local authorities and abolished the second tier of town councils.

Participation aimed to build trust between NATO and other European and former Soviet states while preserving Irish neutrality. It gave a small, well-equipped force of roughly 10,000 regulars a formal channel of co-operation with the alliance.

Ireland adopted the common European currency at its launch in 1999.

The agreement, reached on 10 April 1998 by the British and Irish governments and Northern Ireland's parties and endorsed by referendums in both parts of Ireland weeks later, ended the main phase of the Troubles, created power-sharing government in Northern Ireland and established the North/South Ministerial Council for cross-border policy co-operation. The Republic removed its territorial claim to Northern Ireland from Articles 2 and 3 of the Constitution and thereafter used 'Ireland' as its name in dealings with the UK.

Established in 1997, the authority oversaw regeneration including the Convention Centre Dublin and Grand Canal Theatre. The area's transformation culminated in Capital Dock, completed in 2018 as the tallest building in the Republic at 79 metres.

The referendum ended a prohibition rooted in Catholic social teaching, following the relaxation of contraception controls in 1979. Divorce rates remained very low by EU standards, at 0.7 divorced people per 1,000 population in 2011.

Liberal economic policies enacted after EC accession produced sustained rapid growth between 1995 and 2007. Global capital markets financed a build-up of debt, with Irish banks borrowing well beyond their domestic deposit base, leaving the economy exposed when support was withdrawn.

State support promoted indigenous film-making while attracting international productions such as Braveheart and Saving Private Ryan. The sector became a significant cultural export from the 1990s onwards.

No single-party government has held office since 1989, making coalition formation the customary route to power. The 174-member Dáil is elected by proportional representation using the single transferable vote in multi-seat constituencies.

Reforms included tax cuts, welfare reform, increased competition and a ban on borrowing to fund current spending, and were continued by successive Fianna Fáil/Labour and Fine Gael/Labour/Democratic Left governments. This policy shift underpinned the Celtic Tiger boom of the following decade.

The IFSC marked the start of the transformation of Ireland's tax policy into an instrument of industrial strategy. Its regime was extended nationwide in 2003 when corporation tax was cut from 32% to 12.5%, drawing large-scale US multinational investment.

Contraception had been legally controlled until 1979, reflecting Catholic Church influence over social legislation. Its liberalisation marked an early step in the secularisation of Irish society.
