Question: Who was the man who won Irish Presidency and also led the introduction of the Constitution of Ireland?
Context: Éamon de Valera ( ; ] ; first registered as George de Valero; changed some time before 1901 to Edward de Valera; 14 October 1882 – 29 August 1975) was a prominent politician and statesman in 20th-century Ireland.  His political career spanned over half a century, from 1917 to 1973; he served several terms as head of government and head of state.  He also led the introduction of the Constitution of Ireland. The economic history of the Republic of Ireland effectively began in 1922, when the then Irish Free State won independence from the United Kingdom.  The state was plagued by poverty and emigration until the 1960s when an upturn led to the reversal of long term population decline.  However, global and domestic factors combined in the 70s and 80s to return the country to poor economic performance and emigration.  The 1990s, however saw the beginning of unprecedented economic success, in a phenomenon known as the "Celtic Tiger", which continued until the 2008 global financial crisis, specifically the post-2008 Irish economic downturn.  It also led to the Republic of Ireland becoming the most indebted state in the European Union.  As of 2015, the Republic has returned to growth, expected to be the fastest growing country in Europe once again for that year, though unemployment and underemployment remain high. The Irish presidential election of 1959 was held on 17 June 1959.  Fianna Fáil's founder and longtime leader, Taoiseach Éamon de Valera (under pressure from members of his party) decided to leave active party politics and seek the presidency.  The main opposition party, Fine Gael, decided to run its defeated candidate in 1945, Seán Mac Eoin, against him.  As expected, Éamon de Valera won the presidency. The Constitution of Ireland plebiscite, also known as the Plebiscite on the Draft Constitution, was a plebiscite held in the Irish Free State to approve the adoption of a new constitution for the country.  The vote was held on 1 July 1937, the same day as the general election.  It was passed by a plurality, with 56% of voters in favour, comprising 38.6% of the whole electorate.  As a result, the current Constitution of Ireland came into effect on 29 December 1937, ending the Irish Free State.  It was the only plebiscite to take place in the Irish Free State.  It was also the only referendum that was officially called a plebiscite in the history of the country; all subsequent votes of this nature have taken place under the provisions of the current Irish constitution and are referred to as referendums. Crotty v.  An Taoiseach was a landmark decision of the Irish Supreme Court which found that Ireland could not ratify the Single European Act unless the Irish Constitution was first changed to permit its ratification.  The case taken by Raymond Crotty directly led to the Tenth Amendment of the Constitution of Ireland (which authorised the ratification of the Single Act) and established that significant changes to European Union treaties required an amendment to the Irish constitution before they could be ratified by Ireland.  As a consequence, the Republic of Ireland, uniquely in the EU, requires a plebiscite for every new, or substantive change to a, European Union Treaty. The Constitution of the Irish Free State (Irish: "Bunreacht Shaorstáit Eireann" ) was the second constitution of the independent Irish state.  It was adopted by Act of Dáil Éireann sitting as a constituent assembly on 25 October 1922.  In accordance with Article 83 of the Constitution, the Irish Free State Constitution Act 1922 of the British Parliament, which came into effect upon receiving the royal assent on 5 December 1922, provided that the Constitution would come into effect upon the issue of a Royal Proclamation, which was done on 6 December 1922.  In 1937 the Constitution of the Irish Free State was replaced by the modern Constitution of Ireland following a referendum. The Constitution of Dáil Éireann (Irish: "Bunreacht Dála Éireann" ), more commonly known as the Dáil Constitution, was the constitution of the 1919–22 Irish Republic.  It was adopted by the First Dáil at its first meeting on 21 January 1919 and remained in force for four years.  As adopted it consisted of only five short articles.  Article 1 declared that the Dáil had "full powers to legislate" and would consist of representatives elected in elections conducted by the British government.  For the exercise of executive power it created a cabinet, answerable to the Dáil, called the Aireacht (or Ministry), headed by a prime minister called the "Príomh Aire" (in practice also known as the President of Dáil Éireann).  The constitution made no reference to a judiciary but this did not prevent the Dáil from establishing a system of Dáil Courts.  The final article of the constitution declared that it was intended to be a provisional document, in the sense that it was subject to amendment.  As adopted the constitution came to only around 370 words.  In comparison, the modern Constitution of Ireland has approximately 16,000 words.  Overall, the structure of the document was roughly as follows: The Ireland 1990 50 ECU coin was issued in 1990.  It is a gold commemorative coin with milled edge and medallic alignment.  It was minted at the Currency Centre, Dublin, Ireland.  This medal-coin was issued to commemorate the Irish Presidency of the European Economic Community, hence the denomination in ECU.  It was the first Irish gold coin to have been issued since 1646. The National Monument to the U.S. Constitution (also known as the Constitution Bicentennial Monument) is a monument commissioned of Australian artist Brett-Livingstone Strong by Warren E. Burger, Chairman of the Commission on the Bicentennial of the United States Constitution, to commemorate the 200th anniversary of the signing of the United States Constitution.  One of a pair created by Strong to commemorate historic anniversaries, along with The United States Presidency Monument, it was dedicated by President Ronald Reagan at Independence Hall in Philadelphia on September 17, 1987.  Both monuments are the property of the Global EventMakers,Inc., a Florida-based company with principal offices in Richmond, Virginia.  The monument has been transported for display at several public events around the country and was scheduled to begin a twenty-city traveling exhibit as part of the Spirit of Freedom Tour beginning in September 2009.  Due to poor economic conditions, The Tour never commenced; however the Monuments accompanying original replicas of the United States Constitution and Bill of Rights are being produced for placement in America's schools.  All rights to the Constitution Monument and the Original Replicas of the Constitution were transferred to The American Constitution Spirit Foundation, a Virginia non-profit, in March 2010.  The Foundation plans to find a permanent home for the monument during 2013. The Constitution of 1925 was the constitution in force in Chile between 1925 and 1973 when the Government Junta suspended it.  In the 1920s Chile had a severe social and economic crisis that led to the loss of prestige for old ruling class, labeled oligarchy in Chilean historiography, and the rise of a more sensibilized populist government led by Arturo Alessandri.  In 1924 Alessandri was outed in a coup, but was called back in 1925 to complete his mandate.  Alessandri then used his presidency to draft a new constitution to replace the Constitution of 1833.  The constitution was approved by plebiscite by 134,421 voters on August 30 of 1925.  Prominent features of the constitution were:
