President of Dáil Éireann in the context of "W. T. Cosgrave"

Arthur Joseph Griffith (Irish: Art Seosamh Ó Gríobhtha or Art Ó Gríofa; 31 March 1871 – 12 August 1922) was an Irish writer, newspaper editor and politician who founded the political party Sinn Féin. He led the Irish delegation at the negotiations that produced the 1921 Anglo-Irish Treaty, and served as the president of Dáil Éireann from January 1922 until his death that August.

After a short spell in South Africa, Griffith founded and edited the Irish nationalist newspaper The United Irishman in 1899. In 1904, he wrote The Resurrection of Hungary: A Parallel for Ireland, which advocated the withdrawal of Irish members from the Parliament of the United Kingdom and the setting up of the institutions of government at home in Ireland, a policy that became known as Sinn Féin (ourselves). On 28 November 1905, he presented "The Sinn Féin Policy" at the first annual convention of his organisation, the National Council; the occasion is marked as the founding date of the Sinn Féin party. Griffith took over as president of Sinn Féin in 1911, but at that time the organisation was still small.

The ministry of Dáil Éireann (Irish: Aireacht Dáil Éireann) was the cabinet of the 1919–1922 Irish Republic during the Irish War of Independence. The ministry was originally established by the Dáil Constitution adopted by the First Dáil on 21 January 1919, after it issued the Declaration of Independence. This constitution provided for a cabinet consisting of a head of government, known as the Príomh Aire or President of Dáil Éireann, and four other ministers. The Irish Republic modelled itself on the parliamentary system of government and so its cabinet was appointed by and answerable to the Dáil. Under the constitution the President was elected by the Dáil, while the remaining ministers were nominated by the President and then ratified by the Dáil. The Dáil could dismiss both the cabinet as a whole and individual ministers by passing a resolution. Ministers could also be dismissed by the President.

A number of changes were made to the cabinet system after its adoption in January 1919. The number of ministers was increased in April 1919. As established in 1919, the Irish Republic had no explicit head of state; in 1921 the head of the ministry was renamed as President of the Republic. For a brief period the members of this president's cabinet became known as "secretaries of state" rather than ministers. When the Fourth ministry assumed office in 1922 after the approval of the Anglo-Irish Treaty, with Arthur Griffith as its head, cabinet members were once again described as ministers and Griffith adopted the title of President of Dáil Éireann.

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 operation until 6 December 1922. As adopted it consisted of five 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 Ministry (Irish: Aireacht), headed by a prime minister called the "Príomh Aire" (in practice also known as the President of Dáil Éireann). The constitution was limited to an outline of the functions of the legislature and the executive; the Dáil later established a system of Dáil Courts, but there was no provision in the constitution on a judiciary. 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 as follows:

• Article 1: Dáil Éireann
• Article 2: Ministry of Dáil Éireann
• Article 3: Chairman of the Dáil
• Article 4: Finance
• Article 5: Amendments
