Éamon de Valera was born on 14 October 1882 in New York City, the son of Catherine Coll, who was originally from Bruree, County Limerick, and Juan Vivion de Valera, described on the birth certificate as a Spanish artist born in 1853 in the Basque Country, Spain. He was born at the Nursery and Child’s Hospital, Lexington Avenue, a home for destitute orphans and abandoned children. His parents were reportedly married on 18 September 1881 at St Patrick’s Church in Jersey City, New Jersey, but archivists have not located any marriage certificate or any birth, baptismal, or death certificate information for anyone called Juan Vivion de Valera (nor for “de Valeros”, an alternative spelling). On de Valera’s original birth certificate, his name is given as George de Valero and his father is listed as Vivion de Valero. Although he was known as Edward de Valera before 1901, a fresh birth certificate was issued in 1910, in which his first name was officially changed to Edward and his father’s surname given as “de Valera”. As a child, he was known as “Eddie” or “Eddy”.

According to Coll, Juan Vivion died in 1885 leaving Coll and her child in poor circumstances. Éamon was taken to Ireland by his uncle Ned at the age of two. When his mother remarried in the mid-1880s, he was not brought back to live with her, but was reared by his grandmother, Elizabeth Coll, her son Patrick and her daughter Hannie, in Bruree, County Limerick. He was educated locally at Bruree National School, County Limerick and C.B.S. Charleville, County Cork. Aged sixteen, he won a scholarship. He was not successful in enrolling at two colleges in Limerick, but was accepted at Blackrock College, Dublin, at the instigation of his local curate.

At the end of his first year at Blackrock College he was student of the year. He also won further scholarships and exhibitions and in 1903 was appointed teacher of mathematics at Rockwell College, County Tipperary. It was here that de Valera was first given the nickname “Dev” by a teaching colleague, Tom O’Donnell. In 1904, he graduated in mathematics from the Royal University of Ireland. He then studied for a year at Trinity College Dublin but, owing to the necessity of earning a living, did not proceed further and returned to teaching, this time at Belvedere College. In 1906, he secured a post as a teacher of mathematics at Carysfort Teachers’ Training College for women in Blackrock, Dublin. His applications for professorships in colleges of the National University of Ireland were unsuccessful, but he obtained a part-time appointment at Maynooth and also taught mathematics at various Dublin schools, including Castleknock College (1910–1911; under the name Edward de Valera) and Belvedere College.

As a young Gaeilgeoir (Irish speaker), de Valera became an activist for the Irish language. In 1908, he joined the Árdchraobh of Conradh na Gaeilge (the Gaelic League), where he met Sinéad Flanagan, a teacher by profession and four years his senior. They were married on 8 January 1910 at St Paul’s Church, Arran Quay, Dublin.

While he was already involved in the Gaelic Revival, de Valera’s involvement in the political revolution began on 25 November 1913, when he joined the Irish Volunteers. The organisation was formed to oppose the Ulster Volunteers and ensure the enactment of the Irish Parliamentary Party’s Third Home Rule Act won by its leader John Redmond. After the outbreak of World War I in August 1914, de Valera rose through the ranks and it was not long before he was elected captain of the Donnybrook branch. Preparations were pushed ahead for an armed revolt, and he was made commandant of the Third Battalion and adjutant of the Dublin Brigade. He took part in the Howth gun-running. He was sworn by Thomas MacDonagh into the oath-bound Irish Republican Brotherhood, which secretly controlled the central executive of the Volunteers. He opposed secret societies, but this was the only way he could be guaranteed full information on plans for the Rising.

On 24 April 1916, the Easter Rising began. Forces commanded by de Valera occupied Boland’s Mill on Grand Canal Street in Dublin. His chief task was to cover the southeastern approaches to the city. After a week of fighting, the order came from Pádraig Pearse to surrender. De Valera was court-martialled, convicted, and sentenced to death, but the sentence was immediately commuted to penal servitude for life.

De Valera was among the few republican leaders the British did not execute. It has been argued that his life was saved by four facts. First, he was one of the last to surrender and he was held in a different prison from other leaders, thus his execution was delayed by practicalities. Second, the US Consulate in Dublin made representations before his trial (i.e., was he actually a United States citizen and if so, how would the United States react to the execution of one of its citizens?) while the full legal situation was clarified. The UK was trying to bring the US into the war in Europe at the time, and the Irish American vote was important in US politics. Third, when Lt-Gen Sir John Maxwell reviewed his case he said, “Who is he? I haven’t heard of him before. I wonder would he be likely to make trouble in the future?” On being told that de Valera was unimportant, he commuted the court-martial’s death sentence to life imprisonment. De Valera had no Fenian family or personal background and his MI5 file in 1916 was very slim, detailing only his open membership in the Irish Volunteers. Fourth, by the time de Valera was court-martialled on 8 May, political pressure was being brought to bear on Maxwell to halt the executions; Maxwell had already told British Prime Minister H. H. Asquith that only two more were to be executed, Seán Mac Diarmada and James Connolly, although they were court-martialled the day after de Valera. His late trial, representations made by the American Consulate, his lack of Fenian background and political pressure all combined to save his life, though had he been tried a week earlier he would probably have been shot.

After imprisonment in Dartmoor, Maidstone and Lewes prisons, de Valera and his comrades were released under an amnesty in June 1917. On 10 July 1917, he was elected a member of parliament (MP) for East Clare (the constituency which he represented until 1959) in a by-election caused by the death of the previous incumbent Willie Redmond, brother of the Irish Party leader John Redmond who had died fighting in World War I. In the 1918 general election he was elected both for that seat and Mayo East. But because most other Irish rebellion leaders were dead, in 1917 he was elected President of Sinn Féin, the party which had been blamed incorrectly for provoking the Easter Rising. This party became the political vehicle through which the survivors of the Easter Rising channelled their republican ethos and objectives. The previous President of Sinn Féin, Arthur Griffith, had championed an Anglo-Irish dual-monarchy based on the Austro-Hungarian model, with independent legislatures for both Ireland and Britain.

Sinn Féin won a huge majority in the 1918 general election, largely thanks to the British executions of the 1916 leaders, the threat of conscription with the Conscription Crisis of 1918 and the first-past-the-post ballot. They won 73 out of 105 Irish seats, with about 47% of votes cast. 25 seats were uncontested. On 21 January 1919, 27 Sinn Féin MPs (the rest were imprisoned or impaired), calling themselves Teachtaí Dála (TDs), assembled in the Mansion House in Dublin and formed an Irish parliament, known as Dáil Éireann (translatable into English as the Assembly of Ireland). The Ministry of Dáil Éireann was formed, under the leadership of the Príomh Aire (also called President of Dáil Éireann) Cathal Brugha. De Valera had been re-arrested in May 1918 and imprisoned and so could not attend the January session of the Dáil. He escaped from Lincoln Gaol, England in February 1919. As a result, he replaced Brugha as Príomh Aire in the April session of Dáil Éireann.

De Valera managed to raise $5,500,000 from American supporters, an amount that far exceeded the hopes of the Dáil. Of this, $500,000 was devoted to the American presidential campaign in 1920, helping him gain wider public support there. In 1921, it was said that $1,466,000 had already been spent, and it is unclear when the net balance arrived in Ireland. Recognition was not forthcoming in the international sphere. He also had difficulties with various Irish-American leaders, such as John Devoy and Judge Daniel F. Cohalan, who resented the dominant position he established, preferring to retain their control over Irish affairs in the United States.

In January 1921, in his first appearance in the Dáil, after his return to a country gripped by the War of Independence, de Valera introduced a motion calling on the IRA to desist from ambushes and other tactics that were allowing the British to successfully portray it as a terrorist group, and to take on the British forces with conventional military methods. This they strongly opposed, and de Valera relented, issuing a statement expressing support for the IRA, and claimed it was fully under the control of the Dáil. He then, along with Cathal Brugha and Austin Stack, brought pressure to bear on Michael Collins to undertake a journey to the United States himself, on the pretext that only he could take up where de Valera had left off. Collins successfully resisted this move and stayed in Ireland. In the elections of May 1921, all candidates in Southern Ireland were returned unopposed, and Sinn Féin secured some seats in Northern Ireland. Following the Truce of July 1921 that ended the war, de Valera went to see Prime Minister David Lloyd George in London on 14 July. No agreement was reached, and by then the Parliament of Northern Ireland had already met. It became clear that neither a republic, nor independence for all 32 counties, was going to be offered; Lloyd George told de Valera he could “put a soldier in Ireland for every man, woman and child in it” if the IRA did not immediately agree to stop fighting. In August 1921, de Valera secured Dáil Éireann approval to change the 1919 Dáil Constitution to upgrade his office from prime minister or chairman of the cabinet to a full President of the Republic. Declaring himself now the Irish equivalent of King George V, he argued that as Irish head of state, in the absence of the British head of state from the negotiations, he too should not attend the peace conference called the Treaty Negotiations (October–December 1921) at which British and Irish government leaders agreed to the effective independence of twenty-six of Ireland’s thirty-two counties as the Irish Free State, with Northern Ireland choosing to remain under British sovereignty. It is generally agreed by historians that whatever his motives, it was a mistake for de Valera not to have travelled to London.

The Republic’s delegates to the Treaty Negotiations were accredited by President de Valera and his cabinet as plenipotentiaries (that is, negotiators with the legal authority to sign a treaty without reference back to the cabinet), but were given secret cabinet instructions by de Valera that required them to return to Dublin before signing the Treaty. The Treaty proved controversial in Ireland insofar as it replaced the Republic by a dominion of the British Commonwealth with the King represented by a Governor-General of the Irish Free State. The Irish delegates Arthur Griffith, Robert Barton, and Michael Collins supported by Erskine Childers as Secretary-General set up their delegation headquarters at 22 Hans Place in Knightsbridge. It was there, at 11.15 am on 5 December 1921, that the decision was made to recommend the Treaty to Dáil Éireann; the Treaty was finally signed by the delegates after further negotiations which closed at 02:20 on 6 December 1921.

Ireland’s dominant political personality for many decades, de Valera received numerous honours. He was elected Chancellor of the National University of Ireland in 1921, holding the post until his death. Pope John XXIII bestowed on him the Order of Christ. He received honorary degrees from universities in Ireland and abroad. In 1968, he was elected a Fellow of the Royal Society (FRS), a recognition of his lifelong interest in mathematics. He also served as a member of the Parliament of Northern Ireland (for Down from 1921 to 1929 and for South Down from 1933 to 1937), although he held to the republican policy of abstentionism and did not take his seat in Stormont.

De Valera baulked at the agreement. His opponents claimed that he had refused to join the negotiations because he knew what the outcome would be and did not wish to receive the blame. De Valera claimed that he had not gone to the treaty negotiations because he would be better able to control the extremists at home, and that his absence would allow leverage for the plenipotentiaries to refer back to him and not be pressured into any agreements. Because of the secret instructions given to the plenipotentiaries, he reacted to news of the signing of the Treaty not with anger at its contents (which he refused even to read when offered a newspaper report of its contents), but with anger over the fact that they had not consulted him, their president, before signing. His ideal drafts, presented to a secret session of the Dáil during the Treaty Debates and publicised in January 1922, were ingenious compromises but they included dominion status, the Treaty Ports, the fact of partition subject to veto by the parliament in Belfast, and some continuing status for the King as head of the Commonwealth. Ireland’s share of the imperial debt was to be paid.

After the Treaty was narrowly ratified by 64 to 57, de Valera and a large minority of Sinn Féin TDs left Dáil Éireann. He then resigned and Arthur Griffith was elected President of Dáil Éireann in his place, though respectfully still calling him ‘The President’. On a speaking tour of the more republican province of Munster, starting on 17 March 1922, de Valera made controversial speeches at Carrick on Suir, Lismore, Dungarvan and Waterford, saying that: “If the Treaty were accepted, [by the electorate] the fight for freedom would still go on, and the Irish people, instead of fighting foreign soldiers, will have to fight the Irish soldiers of an Irish government set up by Irishmen.” At Thurles, several days later, he repeated this imagery and added that the IRA: “..would have to wade through the blood of the soldiers of the Irish Government, and perhaps through that of some members of the Irish Government to get their freedom.” In a letter to the Irish Independent on 23 March de Valera accepted the accuracy of their report of his comment about “wading” through blood, but deplored that the newspaper had published it.

Relations between the new Irish government, which was backed by most of the Dáil and the electorate, and the anti-Treatyites under the nominal leadership of de Valera, now descended into the Irish Civil War (June 1922 to May 1923), in which the pro-treaty Free State forces defeated the anti-Treaty IRA. Both sides had wanted to avoid civil war, but fighting broke out over the takeover of the Four Courts in Dublin by anti-Treaty members of the IRA. These men were not loyal to de Valera and initially were not even supported by the executive of the anti-Treaty IRA. However, Michael Collins was forced to act against them when Winston Churchill threatened to re-occupy the country with British troops unless action was taken. When fighting broke out in Dublin between the Four Courts garrison and the new Free State Army, republicans backed the IRA men in the Four Courts and civil war broke out. De Valera, though he held no military position, backed the anti-Treaty IRA or “Irregulars” and said that he was re-enlisting in the IRA as an ordinary volunteer. On 8 September 1922, he met in secret with Richard Mulcahy in Dublin to try to halt the fighting. However, according to de Valera, they “could not find a basis” for agreement.

Though nominally head of the anti-Treatyites, de Valera had little influence. He does not seem to have been involved in any fighting and had little or no influence with the military republican leadership – headed by IRA Chief of Staff, Liam Lynch. De Valera and the anti-Treaty TDs formed a “republican government” on 25 October 1922 from anti-Treaty TDs to “be temporarily the Supreme Executive of the Republic and the State, until such time as the elected Parliament of the Republic can freely assemble, or the people being rid of external aggression are at liberty to decide freely how they are to be governed”. However, it had no real authority and was a pale shadow of the republican Dáil government of 1919–21, which had provided an alternative government to the British administration.

In March 1923, de Valera attended the meeting of the IRA Army Executive to decide on the future of the war. He was known to be in favour of a truce but he had no voting rights and it was narrowly decided to continue hostilities. The leader of the Free State, W. T. Cosgrave, insisted that there could be no acceptance of a surrender without disarming.

On 30 May 1923, the IRA’s new Chief of Staff Frank Aiken (Lynch had been killed) called a ceasefire and ordered volunteers to “dump arms”. De Valera, who had wanted an end to the internecine fighting for some time, backed the ceasefire order with a message in which he called the anti-Treaty fighters “the Legion of the Rearguard”, saying that “The Republic can no longer be successfully defended by your arms. Further sacrifice on your part would now be in vain and the continuance of the struggle in arms unwise in the national interest and prejudicial to the future of our cause. Military victory must be allowed to rest for the moment with those who have destroyed the Republic. Other means must be sought to safeguard the nation’s right.”

After the IRA dumped their arms rather than surrender them or continue a now fruitless war, de Valera returned to political methods. In 1924, he was arrested in Newry for “illegally entering Northern Ireland” and held in solitary confinement for a month in Crumlin Road Gaol, Belfast.

However, one of his colleagues, Seán Lemass, convinced de Valera to found a new republican party. In March 1926, with Lemass, Constance Markievicz and others, de Valera formed a new party, Fianna Fáil (The Warriors of Destiny), a party that was to dominate 20th-century Irish politics. While Sinn Féin still held to an abstentionist line, Fianna Fáil was dedicated to republicanising the Free State from within if it gained power.

Having attracted most of Sinn Féin’s branches due to Lemass’ organisational skill, the new party made swift electoral gains in the general election on 9 June 1927. In the process, it took much of Sinn Féin’s previous support, winning 44 seats to Sinn Féin’s five. It refused to take the Oath of Allegiance (portrayed by opponents as an ‘Oath of Allegiance to the Crown’ but actually an Oath of Allegiance to the Irish Free State with a secondary promise of fidelity to the King in his role in the Treaty settlement).

The oath was largely the work of Michael Collins and based on three sources: British oaths in the dominions, the oath of the Irish Republican Brotherhood, and a draft oath prepared by de Valera in his proposed treaty alternative, “Document No. 2”). De Valera began a legal case to challenge the requirement that members of his party take the Oath, but the assassination of the Vice-President of the Executive Council (deputy prime minister) Kevin O’Higgins on 10 July 1927 led the Executive Council under W. T. Cosgrave to introduce a Bill on 20 July requiring all Dáil candidates to promise on oath that if they were elected they would take the Oath of Allegiance. Forced into a corner, and faced with the option of staying outside politics forever or taking the oath and entering, de Valera and his TDs took the Oath of Allegiance on 12 August 1927, though de Valera himself described the Oath as “an empty political formula”.

The Oath of Allegiance was abolished, as were appeals to the Judicial Committee of the Privy Council. The opposition-controlled Senate, when it protested and slowed down these measures, was also abolished. In 1931, the British Parliament passed the Statute of Westminster, which established the legislative equal status of the self-governing Dominions of the then British Commonwealth, including the Irish Free State, to one another and the United Kingdom. Though a few constitutional links between the Dominions and the United Kingdom remained, this is often seen as the moment at which the Dominions became fully sovereign states.

In the 1932 general election Fianna Fáil secured 72 seats and became the largest party in the Dáil, although without a majority. Some Fianna Fáil members arrived at the first sitting of the new Dáil carrying arms, amid fears that Cumann na nGaedheal would not voluntarily surrender power. However, the transition was peaceful. De Valera was elected President of the Executive Council (Prime Minister) by the Dáil by a vote of 81–68, with the support of the Labour Party and Independent politicians, and took office on 9 March.

After De Valera had urged King George V to dismiss McNeill as Governor-General, the King suggested an alternative course of action: that McNeill, instead, carry on a while longer as viceroy and only then resign, which he did on 1 November 1932. Subsequently, a 1916 veteran, Domhnall Ua Buachalla, was appointed Governor-General. To strengthen his position against the opposition in the Dáil and Seanad, de Valera directed the Governor-General to call a snap election in January 1933 and de Valera’s party won 77 seats, giving Fianna Fáil an overall majority. Under de Valera’s leadership, Fianna Fáil won further general elections in 1937, 1938, 1943, and 1944.

De Valera took charge of Ireland’s foreign policy as well by also acting as Minister for External Affairs. In that capacity, he attended meetings of the League of Nations. He was president of the Council of the League on his first appearance at the league in Geneva, Switzerland, in 1932 and, in a speech that made a worldwide impression, appealed for genuine adherence by its members to the principles of the covenant of the league. In 1934, he supported the admission of the Soviet Union into the league. In September 1938, he was elected nineteenth president of the Assembly of the League, a tribute to the international recognition he had won by his independent stance on world questions.

The ACA changed its name to the National Guard under O’Duffy and adopted the uniform of black berets and blue shirts, using the straight-armed salute, and were nicknamed the Blueshirts. They were outwardly fascist and planned a march in August 1933 through Dublin to commemorate Michael Collins, Kevin O’Higgins, and Arthur Griffith. This march struck parallels with Mussolini’s march on Rome (1922), in which he had created the image of having toppled the democratic government in Rome. De Valera revived a military tribunal, which had been set up by the previous administration, to deal with the matter. O’Duffy backed down when the National Guard was declared an illegal organisation and the march was banned. Within a few weeks, O’Duffy’s followers merged with Cumann na nGaedhael and the Centre Party to form United Ireland, or Fine Gael, and O’Duffy became its leader. Smaller local marches were scheduled for the following weeks, under different names. Internal dissension set in when the party’s TDs distanced themselves from O’Duffy’s extreme views, and his movement fell asunder.

De Valera, in his capacity as Prime Minister of His Majesty’s Government in the Irish Free State, wrote in July 1936 to King Edward VIII in London indicating that he planned to introduce a new constitution, the central part of which was to be the creation of an office de Valera provisionally intended to call President of Saorstát Éireann (Irish: Uachtarán Shaorstát Éireann), which would replace the Governor-General. De Valera used the sudden abdication of Edward VIII as King to pass two bills: one amended the constitution to remove all mention of the monarch and Governor-General, while the second brought the monarch back, this time through statute law, for use in representing the Irish Free State at a diplomatic level. With the implementation of the Constitution of Ireland (Irish: Bunreacht na hÉireann), the title ultimately given to the president was President of Ireland (Irish: Uachtarán na hÉireann).

The Constitution was approved in a plebiscite on 1 July 1937 and came into force on 29 December 1937.

With the new constitution in place, de Valera determined that the changed circumstances made swift resolution to Ireland’s ongoing trade war with the UK more desirable for both sides — as did the growing probability of the outbreak of war across Europe. In April 1938, de Valera and British Prime Minister Neville Chamberlain signed the Anglo-Irish Trade Agreement, lifting all duties imposed during the previous five years and ending British use of the Treaty Ports it had retained in accordance with the Anglo-Irish Treaty. The return of the ports was of particular significance, since it ensured Irish neutrality during the coming Second World War.

By September 1939, a general European war was imminent. On 2 September, de Valera advised Dáil Éireann that neutrality was the best policy for the country. This policy had overwhelming political and popular support, though some advocated Irish participation in the War on the Allied side, while others, believing that “England’s difficulty is Ireland’s opportunity”, were pro-German. Strong objections to conscription in the North were voiced by de Valera. In June 1940, to encourage the neutral Irish state to join with the Allies, Winston Churchill indicated to de Valera that the United Kingdom would push for Irish unity, but believing that Churchill could not deliver, de Valera declined the offer. The British did not inform the Government of Northern Ireland that they had made the offer to the Irish government, and De Valera’s rejection was not publicised until 1970. The government secured wide powers for the duration of the Emergency, such as internment, censorship of the press and correspondence, and the government control of the economy. The Emergency Powers Act lapsed on 2 September 1946, though the State of Emergency declared under the constitution was not lifted until the 1970s. This status remained throughout the war, despite pressure from Chamberlain and Churchill. However, de Valera did respond to a request from Northern Ireland for fire tenders to assist in fighting fires following the 1941 Belfast Blitz.

Persistent claims that de Valera sent a personal note of congratulation to Subhas Chandra Bose upon his declaration of the Azad Hind (Free India) government in 1943, have been shown to be inaccurate, and largely a misrepresentation by Japanese consular staff in Dublin of a statement by a small and unofficial Republican group unconnected to the Irish government.

Controversially, de Valera formally offered his condolences to the German Minister in Dublin on the death of Adolf Hitler in 1945, in accordance with diplomatic protocol. This did some damage to Ireland, particularly in the United States – and soon afterwards de Valera had a bitter exchange of words with Winston Churchill in two famous radio addresses after the end of the war in Europe. De Valera denounced reports of Bergen-Belsen concentration camp as “anti-national propaganda”; according to Bew, this was not out of disbelief but rather because the Holocaust undermined the assumptions underlying Irish neutrality: moral equivalence between the Allies and the Axis, and the idea that the Irish were the most persecuted people in Europe.

The de Valera government was reputedly harsh with Irish Army deserters who had enlisted to fight with the Allied Armies against the Axis. The legislation in question was the Emergency Powers (No. 362) order which was passed in August 1945. On 18 October 1945, Thomas F. O’Higgins moved to annul the order. He did not condone desertion, but felt that the order was specifically harsh on those deserters who had served in the Allied forces. General Richard Mulcahy also spoke against the Order, disagreeing with the way in which it applied to enlisted men and not to officers. It was revoked with effect from 1 August 1946, but was in effect continued by section 13 of the Defence Forces (Temporary Provisions) Act, 1946.

After de Valera had spent sixteen years in power without answering the crucial questions of partition and republican status the public demanded a change from Fianna Fáil government. In the 1948 election, de Valera lost the outright majority he had enjoyed since 1933. It initially looked as if the National Labour Party would give Fianna Fáil enough support to stay in office as a minority government, but National Labour insisted on a formal coalition agreement, something de Valera was unwilling to concede. However, while Fianna Fáil was six seats short of a majority, it was still by far the largest party in the Dáil, with 37 more TDs than the next largest party and rival, Fine Gael (the successor to Cumann na nGaedheal). Conventional wisdom held that de Valera would remain Taoiseach with the support of independent deputies.

De Valera, now Leader of the Opposition, left the actual parliamentary practice of opposing the government to his deputy, Seán Lemass, and himself embarked on a world campaign to address the issue of partition. He visited the United States, Australia, New Zealand and India, and in the latter country, was the last guest of the Governor-General, Lord Mountbatten of Burma, before he was succeeded by the first Indian-born Governor-General. In Melbourne, Australia, de Valera was feted by the powerful Catholic Archbishop Daniel Mannix, at the centenary celebrations of the diocese of Melbourne. He attended mass-meetings at Xavier College, and addressed the assembled Melbourne Celtic Club. In October 1950, just thirty years after his dramatic escape from Lincoln Gaol, he returned to Lincoln and received the freedom of the gaol. The Anti-Partition of Ireland League of Great Britain marked the occasion with a dinner in his honour and the toast was ‘Anglo-Irish Friendship’. A key message in de Valera’s campaign was that Ireland could not join the recently established North Atlantic Treaty Organization as long as Northern Ireland was in British hands; although Costello’s government favoured alliance with NATO, de Valera’s approach won more widespread support and prevented the state from signing the treaty.

Returning to Ireland during the Mother and Child Scheme crisis that racked the First Inter-Party Government, de Valera kept silent as Leader of the Opposition, preferring to stay aloof from the controversy. That stance helped return de Valera to power in the 1951 general election, but without an overall majority. His and Fianna Fáil’s popularity was short-lived, however; his government introduced severe, deflationary budgetary and economic policies in 1952, causing a political backlash that cost Fianna Fáil several seats in the Dáil in by-elections of 1953 and early 1954. Faced with a likely loss of confidence in the Dáil, de Valera instead called an election in May 1954, in which Fianna Fáil was defeated and a Second Inter-Party Government was formed with John A. Costello again as Taoiseach.

De Valera’s final term as Taoiseach also saw the passage of numerous reforms in health and welfare. In 1952, unemployment insurance was extended to male agricultural employees, child allowances were extended to the second child, and a maternity allowance for insured women was introduced. A year later, eligibility for maternity and child services and public hospital services was extended to approximately 85% of the population.

On 16 September 1953, de Valera met British Prime Minister Winston Churchill for the first and only time, at 10 Downing Street. (The two men had seen each other at a party in 1949, but without speaking). He surprised the UK Prime Minister by claiming that if he had been in office in 1948 Ireland would not have left the Commonwealth.

It was during this period that de Valera’s eyesight began to deteriorate and he was forced to spend several months in the Netherlands, where he had six operations. In 1955, while in opposition, de Valera spoke against the formation of a European Parliament and European federalism, noting that Ireland “did not strive to get out of that British domination […] to get into a worse [position]”.

Like the first coalition government, the second lasted only three years. At the general election of 1957, de Valera, then in his seventy-fifth year, won an absolute majority of nine seats, the greatest number he had ever secured. This was the beginning of another sixteen-year period in office for Fianna Fáil. A new economic policy emerged with the First Programme for Economic Expansion. In July 1957, in response to the Border Campaign (IRA), Part II of the Offences Against the State Act was re-activated and he ordered the internment without trial of Republican suspects, an action which did much to end the IRA’s campaign.

While Fianna Fáil remained popular among the electorate, 75-year-old de Valera had begun to be seen by the electorate as too old and out of touch to remain as head of government. At the urging of party officials, de Valera decided to retire from government and the Dáil and instead seek the presidency of Ireland. He won the 1959 presidential election on 17 June 1959 and resigned as Taoiseach, Leader of Fianna Fáil and a TD for Clare, six days later, handing over power to Seán Lemass.

De Valera was inaugurated President of Ireland on 25 June 1959. He was re-elected President in 1966, aged 84, until 2013 a world record for the oldest elected head of state. At his retirement in 1973 at the age of 90, he was the oldest head of state in the world.

A notable failure was his attempt to reverse the provision of the 1937 Constitution in relation to the electoral system. On retiring as Taoiseach in 1959, he proposed that the Proportional Representation system enshrined in that constitution should be replaced. De Valera argued that Proportional Representation had been responsible for the instability that had characterised much of the post war period. A constitutional referendum to ratify this was defeated by the people. One aspect of de Valera’s legacy is that since the foundation of the state, a de Valera has nearly always served in Dáil Éireann. Éamon de Valera served until 1959, his son, Vivion de Valera, was also a Teachta Dála (TD). Éamon Ó Cuív, his grandson, is currently a member of the Dáil while his granddaughter, Síle de Valera is a former TD. Both have served in ministries in the Irish Government.

As President of Ireland, de Valera received many state visits, including the 1963 visit of U.S. President John F. Kennedy. Five months later de Valera attended the state funeral for Kennedy in Washington, D.C. and accompanied a group of 24 Defence Forces cadets who performed a silent drill at his grave site. In June 1964, he returned to Washington, D.C. as the second President of Ireland to address the United States Congress.

In 1966, the Dublin Jewish community arranged the planting and dedication of the Éamon de Valera Forest in Israel, near Nazareth, in recognition of his support for Ireland’s Jews.

In January 1969, de Valera became the first President to address both houses of the Oireachtas, to mark the fiftieth anniversary of the foundation of Dáil Éireann.

In 1969, seventy-three countries sent goodwill messages to NASA for the historic first lunar landing. These messages still rest on the lunar surface and de Valera’s message on behalf of Ireland stated, “May God grant that the skill and courage which have enabled man to alight upon the Moon will enable him, also, to secure peace and happiness upon the Earth and avoid the danger of self-destruction.”

The specific recognition of Roman Catholicism was deleted by the Fifth Amendment of the Constitution of Ireland (1973) and the prohibition of divorce was removed by the Fifteenth Amendment of the Constitution of Ireland (1996). Nevertheless, the Irish Supreme Court declared in 1973 that the 1935 contraception legislation was not repugnant to the Constitution and therefore remained valid.

Éamon de Valera died from pneumonia and heart failure in Linden Convalescent Home, Blackrock, Dublin, on 29 August 1975, aged 92. His wife, Sinéad de Valera, four years his senior, had died the previous January, on the eve of their 65th wedding anniversary. His body lay in state at Dublin Castle and was given a full state funeral on 3 September at St Mary’s Pro-Cathedral, which was broadcast on national television. He is buried in Dublin’s Glasnevin Cemetery with his wife and children.

In January 2017, his grave was vandalised, with the man responsible pleading guilty to criminal damage and receiving a suspended prison sentence.
