Ireland

Ireland (Q27), officially the Republic of Ireland, is a sovereign state occupying most of the island of Ireland in the North Atlantic, with its capital in Dublin. A member of the European Union since 1973, Ireland experienced dramatic economic transformation during the Celtic Tiger boom of the 1990s and 2000s, growing from one of Europe's poorer nations into a high-income economy. The country recognizes both Irish and English as official languages, with English dominant in daily life and Irish preserved in designated Gaeltacht regions. Ireland's literary heritage is extraordinary, having produced Nobel laureates W. B. Yeats and Samuel Beckett alongside modernist giant James Joyce, whose works reshaped the novel form. The landscape ranges from the dramatic Cliffs of Moher on the Atlantic coast to the ancient round towers that dot the countryside as enduring symbols of early medieval monastic culture.

Ireland (Éire), officially the Republic of Ireland, is a sovereign state occupying most of the island of Ireland in the North Atlantic, with Dublin as its capital and largest city. Ireland joined the European Economic Community (now EU) in 1973 and was a founding member of the eurozone in 1999. The country transformed from one of Europe's poorest nations into the "Celtic Tiger" economy during the 1990s, driven by foreign direct investment, a highly educated English-speaking workforce, and favorable corporate tax policies that attracted major technology and pharmaceutical multinationals. The island's cultural legacy is extraordinarily rich, producing literary giants such as W.B. Yeats, James Joyce, Samuel Beckett, and Oscar Wilde, alongside globally celebrated traditions in music, dance, and Gaelic sports. With a population of approximately 5.1 million, Ireland is a parliamentary republic whose constitution (Bunreacht na hÉireann) established the office of President (Uachtarán) and a bicameral legislature (Oireachtas), and the country continues to navigate its complex relationship with Northern Ireland following the 1998 Good Friday Agreement.

Ireland (Q27), officially the Republic of Ireland, is a sovereign state occupying most of the island of Ireland in northwestern Europe, with Dublin as its capital and largest city. Home to approximately 5.1 million people, Ireland is a member of the European Union and experienced rapid economic growth known as the Celtic Tiger during the late 1990s and 2000s. The country recognizes both Irish and English as official languages and is governed as a parliamentary republic from Leinster House in Dublin. Ireland holds a distinguished literary tradition, producing Nobel laureates such as W. B. Yeats and Samuel Beckett, alongside modernist giant James Joyce, and its cultural symbols — the harp, the shamrock, and Guinness — are recognized worldwide.

Ireland — the sovereign state that occupies five-sixths of the island and goes by Éire in Irish, Ireland in English, with Republic of Ireland serving as the legal description rather than the name [1][7] — has just done two things it had never done before. In April 2022 its population crossed five million for the first time since 1851, the Famine year, reaching 5,149,139 [11]. And on 11 November 2025 it inaugurated Catherine Connolly, a left-wing independent from Galway, as President after she beat the Fine Gael candidate by more than thirty points on 914,143 first-preference votes [19][20].

How did a colony become a republic?

The modern Irish state begins with a six-day military failure. On Easter Monday, 24 April 1916, around 1,200 members of the Irish Volunteers and the Irish Citizen Army seized the General Post Office and other Dublin buildings and proclaimed an Irish Republic [2]. The Rising was crushed by 29 April. What turned a defeat into a founding myth was the British response: 16 leaders were executed, 15 by firing squad in Ireland in May 1916 and Roger Casement hanged in London that August [2]. Public opinion, which had been hostile during the Rising itself, swung hard.

By the December 1918 general election Sinn Féin had swept the country. Its winning MPs refused to sit at Westminster and instead convened the First Dáil in Dublin on 21 January 1919, declaring independence the same day. The Irish War of Independence began that morning [3]. The guerrilla war between the Irish Republican Army and Crown forces ran until July 1921, when a truce led to negotiations in London and the Anglo-Irish Treaty signed on 6 December 1921 [4].

The Treaty created the Irish Free State as a self-governing dominion of the British Empire and partitioned the six northeastern counties as Northern Ireland [4]. It split the independence movement: the pro-Treaty side, led by Michael Collins, accepted dominion status as a stepping stone, while the anti-Treaty side, led by Éamon de Valera, rejected the oath of allegiance to the Crown. The Irish Civil War followed from June 1922 to May 1923 — pro-Treaty forces won, but the political fault line of that war became the country's two main parties: Fianna Fáil (anti-Treaty descendants) and Fine Gael (pro-Treaty descendants), a rivalry that still organises Irish politics a century later [5].

Fianna Fáil and Fine Gael are both centre-right, both broadly pro-EU, both broadly pro-business. On policy you can barely tell them apart. The reason they exist as separate parties — and why they refused to share government with each other from 1932 until 2020 — is that their grandparents shot at each other in 1922-23 over whether the Anglo-Irish Treaty's compromise was acceptable. The 2020 grand coalition, renewed after the November 2024 election, ended that taboo nearly a century after the Civil War ended [5][18].

The Free State drafted a new constitution, Bunreacht na hÉireann, ratified by referendum in 1937. It renamed the state Éire / Ireland, declared Irish the first official language, and recognised the special position of the Catholic Church (a clause not removed until 1972) [6]. The final break came with the Republic of Ireland Act 1948, which took effect on 18 April 1949 — leaving the Commonwealth and declaring the state a republic [7]. The 1948 Act is the source of the Costello distinction: "Ireland" is the name; "Republic of Ireland" is the description [7].

How did the poorest country in Western Europe become one of the richest?

For the first forty years of independence Ireland was poor and emigrating. The 1961 census recorded 2.82 million people — fewer than at any point in modern history. Then on 1 January 1973 Ireland joined the European Economic Community alongside the United Kingdom and Denmark, and the slow transformation began [1][14].

The Celtic Tiger arrived in the mid-1990s. From roughly 1995 to 2000 GDP grew at an average of 9.4% a year, driven by US foreign direct investment chasing a young English-speaking workforce inside the EU single market and a corporate tax rate of 12.5% — far below the EU average [13][15]. By 2007 Ireland was richer per head than Britain, France or Germany. Then it crashed.

The 2008 collapse of an over-leveraged property bubble and the banking system that funded it nearly bankrupted the state. On 28 November 2010 Ireland agreed an €85 billion programme of financial assistance from the EU, the IMF and bilateral lenders, signed on 16 December 2010. On 15 December 2013 Ireland exited the programme — the first euro-area country to do so [14].

The 12.5% headline rate survives, but since 1 January 2024 in-scope multinational groups (those with annual revenue above €750 million) face a 15% effective minimum under the OECD Pillar Two rules — applied through an Income Inclusion Rule and a Qualified Domestic Top-up Tax, with the Undertaxed Profits Rule joining from 1 January 2025 [16]. Most companies operating in Ireland still pay 12.5%; the very largest now pay 15% [15][16].

Why did Ireland change its mind about so many things at once?

The 1937 Constitution can only be changed by referendum [6]. That makes the social transformation of the last thirty years legible as a sequence of dated votes. Divorce was legalised by the 15th Amendment on 24 November 1995 — by 50.28% Yes, a margin of about 9,100 votes out of 1.6 million cast [8]. Marriage equality passed by the 34th Amendment on 22 May 2015 with 62.07% Yes, making Ireland the first state in the world to legalise same-sex marriage by popular vote [9]. The 36th Amendment of 25 May 2018 repealed the constitutional ban on abortion (the 8th Amendment) by 66.40% Yes, allowing the Oireachtas to legislate [10].

Underlying these votes is a religious shift. Catholic affiliation in the census fell from 78.3% in 2016 to 69.1% in 2022; those declaring no religion rose to 14.1% — the second-largest group [11]. The country that voted on these questions in the 2010s was no longer the country the 1937 Constitution had described.

What does Irish politics actually look like now?

The Oireachtas in Dublin has two chambers — Dáil Éireann (lower house) and Seanad Éireann (upper house) — and a directly elected non-executive President (Uachtarán na hÉireann) as head of state. Real power sits with the Taoiseach (prime minister) [1][6].

The 2024 general election on 29 November 2024 returned Fianna Fáil as the largest party. After eight weeks of negotiation, Micheál Martin (FF) was elected Taoiseach on 23 January 2025, with Simon Harris (FG) as Tánaiste. The coalition consists of Fianna Fáil, Fine Gael, and a Regional Independent Group of nine independent TDs [18].

Then came the upset. In the 2025 presidential election on 24 October 2025, with Michael D. Higgins's two terms ending, Galway-based independent TD and former Labour parliamentarian Catherine Connolly — running on an explicitly left-wing, anti-militarisation platform — defeated Fine Gael's Heather Humphreys with 63.4% of first-preference votes (914,143 to roughly 421,000) [19][20][21]. She was inaugurated on 11 November 2025 as the tenth President of Ireland [20]. The result is unprecedented: a left independent in the Áras while a centre-right coalition runs the government.

Irish (Gaeilge) is the constitutional first official language [6]. Census 2022 recorded about 1.87 million people with some ability in Irish, but only around 72,000 daily speakers outside the education system [17]. The state has nonetheless invested heavily in international status: after a derogation period that began with EU accession, Irish became a full working language of the European Union on 1 January 2022, meaning all EU legislation is now translated into Irish [17].

A hundred years on, Ireland is still legibly the country that the 1922 Treaty and the 1937 Constitution made — two civil-war parties in coalition, governed by a constitution that can only be amended by the people — but the population it governs has changed almost everything else.

Ireland's measured GDP per capita is roughly $104,000 — among the highest figures on Earth, ahead of the United States, Germany, and almost every other developed economy [1]. Yet the country's own statistics agency publishes an alternative number, GNI*, that lops about 40% off the top and lands closer to €56,000 per head [2]. The gap is not an accounting curiosity; it is a window onto how Ireland actually works.

Why does Ireland have two GDPs?

The short answer is that Ireland's headline GDP measures activity that happens on Irish books rather than activity that benefits Irish residents. A handful of US multinationals — Apple, Google, Meta, Microsoft, Pfizer, and the global aircraft-leasing industry that nests in Dublin for tax reasons — book vast quantities of intellectual property, profits, and aircraft assets through Irish subsidiaries [2]. When a US tech firm "onshores" a multibillion-euro patent portfolio to Dublin, Irish GDP jumps by tens of billions overnight, even though no Irish worker has lifted a finger.

The most famous spike came in 2015, when revised national accounts showed GDP growing by 26.3% in a single year — a figure economist Paul Krugman dubbed "leprechaun economics" [2]. The Central Statistics Office responded by building Modified Gross National Income, written GNI* and pronounced "GNI star," specifically to strip out the distortions [2]. GNI* removes the depreciation of foreign-owned intellectual-property assets, the depreciation of aircraft owned by Irish-resident leasing companies, and the retained earnings of redomiciled corporate headquarters [2]. What is left is closer to the income that actually accrues to people living in Ireland.

GNI* is not a fudge; it is the metric the Irish government uses to plan its budget, calibrate its debt-to-income ratio, and argue with rating agencies [2]. The fact that an OECD country needs a homemade alternative to GDP tells you almost everything about its economic model.

How did 12.5% become Ireland's most important number?

For most of the twentieth century Ireland was poor — emigration outpaced immigration in every decade until the 1990s, and successive governments failed to industrialise [3]. Then, beginning in the late 1980s, the state did three things at once: it opened up to foreign investment, it joined the European single market, and it set its corporate trading-profits tax at a flat 12.5% [4]. The combination, paired with a young, English-speaking, EU-resident workforce, lit the Celtic Tiger — a period of explosive growth from roughly 1995 to 2007 in which Irish living standards converged on, and briefly overtook, the European average [3].

The model bent the country into an unusual shape. American tech and pharmaceutical firms used Ireland as their European base, and aggressive structures like the so-called "Double Irish" let multinationals route global profits through Dublin at single-digit effective rates until the loophole was closed between 2014 and 2020 [4]. By the late 2000s, corporation tax was producing a disproportionate share of state revenue from a handful of payers — a concentration risk the Department of Finance still warns about every budget cycle [4].

It also broke. The 2008 financial crash exposed an Irish banking system inflated by a property bubble, and in November 2010 Ireland accepted an €85 billion bailout from the EU, the IMF, and bilateral lenders [5]. The country exited the programme on 15 December 2013 — the first euro-area state to do so cleanly — but austerity bit hard for the rest of the decade [5].

The corporate-tax story has now been overwritten by the OECD Pillar Two agreement. From 1 January 2024, multinational groups with consolidated revenue of €750 million or more pay a minimum effective rate of 15% in Ireland through an Income Inclusion Rule and a Qualified Domestic Top-up Tax; an Undertaxed Profits Rule was added from 1 January 2025 [6]. The 12.5% headline rate technically survives for everyone below the threshold, but the symbolism is gone: Ireland's most famous number is now 15%, set in Paris [6].

And then came the windfall. In 2016 the European Commission ruled that two Irish tax opinions issued to Apple in 1991 and 2007 amounted to illegal state aid worth €13 billion in unpaid back taxes, and ordered Ireland to recover the money — a decision Ireland and Apple both appealed, on the awkward grounds that the Irish state did not want the cash [7]. The General Court of the EU annulled the order in 2020. Then, on 10 September 2024, the Court of Justice of the European Union reversed the General Court and reinstated the original ruling [7]. The roughly €14 billion sitting in escrow — back taxes plus interest — became Ireland's to keep, an unplanned bonus equivalent to several percent of annual government revenue [7].

GNI* starts from standard Gross National Income and subtracts three items the CSO judges to be artefacts of multinational tax planning: (1) depreciation on foreign-owned domestic intellectual-property assets, (2) depreciation on aircraft owned by Irish-resident leasing companies, and (3) the undistributed profits of corporations that have shifted their tax residency to Ireland without shifting real activity [2]. The result is typically 35-40% lower than GDP. The Fiscal Advisory Council uses GNI* as the denominator for Ireland's debt ratio, where it produces a figure roughly two-thirds higher than the GDP-based version — closer to the country's actual fiscal capacity [2].

What does the constitution that built it say?

The state Apple pays its tax to is younger than most of its neighbours. The Anglo-Irish Treaty of December 1921 ended the War of Independence and created the Irish Free State as a dominion of the British Commonwealth — an outcome that split the independence movement and triggered a civil war in 1922-23 between pro- and anti-Treaty factions [8][9]. The two civil-war sides became Cumann na nGaedheal (later Fine Gael) and Fianna Fáil, and they have organised Irish politics ever since [10].

In 1937, Éamon de Valera's government replaced the Free State constitution with Bunreacht na hÉireann, a new constitution that named the state Éire, or in English Ireland, removed the British monarch from internal affairs, and declared the territory of the state to be the whole island [11]. The document was approved by referendum, and to this day it can only be amended by referendum — the Oireachtas cannot change a comma of it on its own authority [11].

The last loose thread was cut in 1948, when an inter-party government led by Taoiseach John A. Costello passed the Republic of Ireland Act, which came into force on 18 April 1949 and declared the state a republic outside the Commonwealth [12]. The Act drew a careful distinction that Irish lawyers still cite: the name of the state remains Éire / Ireland, while "Republic of Ireland" is its legal description [12].

Where does Ireland sit in Europe — and why is its neutrality argument so heated right now?

Ireland joined the European Economic Community on 1 January 1973, the same day as the United Kingdom and Denmark [3]. Membership reshaped Irish agriculture, opened the British market and then the wider single market, and — when the UK left the EU in 2020 — left Ireland as the only English-speaking common-law jurisdiction inside the bloc, an accident of history that has further sharpened its appeal to American multinationals [3].

Membership of the EU has not translated into membership of NATO. Ireland is militarily neutral, a posture that dates from the Second World War (Irish governments call the period "the Emergency") and that successive governments have framed in terms of independent foreign policy and UN peacekeeping rather than pacifism [13]. The institutional expression of neutrality is the Triple Lock: any deployment of more than twelve Irish Defence Forces personnel overseas requires three separate authorisations — a UN Security Council mandate, a Government decision, and a vote of Dáil Éireann [14].

The Triple Lock is now the most contested item in Irish foreign policy. In 2024 and 2025 the government argued that Russia's veto on the Security Council had effectively given Moscow a veto over Irish peacekeeping, and proposed legislation to remove the UN component while keeping Government and Dáil approval [14]. Opponents — most of the opposition and a sizeable share of the public — argue that severing the UN tie ends meaningful neutrality and pulls Ireland closer to NATO by stealth. The debate has run alongside, and partly poisoned, the rest of the parliamentary session [14].

That session is being run by a coalition of Fianna Fáil, Fine Gael, and the Regional Independent Group, formed after the November 2024 general election; Micheál Martin of Fianna Fáil returned as Taoiseach on 23 January 2025 under a rotation deal with Fine Gael [15]. At the head of the state — a largely ceremonial role, but one with reserve powers over legislation — sits Catherine Connolly, who took office on 11 November 2025 [16]. The country she leads has, against expectations, slightly more people in it than at any point since the Famine, a budget surplus underwritten by the Apple windfall and corporate tax, and an argument with itself about what neutrality means in a Europe at war [13].

The Constitution names Irish as the first official language of the state and English as a second official language [17]. In daily use the balance is reversed: English dominates almost everywhere, while Irish is a community language only in the Gaeltacht regions on the western seaboard, in pockets of Donegal, Galway, Mayo, and Kerry, and to a lesser extent Cork, Waterford, and Meath [17]. All schoolchildren study Irish, road signs are bilingual, and Irish has been an official EU working language since 2022 — a status that translates into a steady demand for Irish-speaking translators in Brussels [17].
