Ministry of Dáil Éireann in the context of "Dáil Constitution"

The Irish Republic (Irish: Poblacht na hÉireann or Saorstát Éireann) was a revolutionary state that declared its independence from the United Kingdom of Great Britain and Ireland in January 1919. The Republic claimed jurisdiction over the whole island of Ireland, but by 1920 its functional control was limited to only 21 of Ireland's 32 counties, and British state forces maintained a presence across much of the north-east, as well as Cork, Dublin and other major towns. The republic was strongest in rural areas, and through its military forces was able to influence the population in urban areas that it did not directly control.

Its origins date back to the Easter Rising of 1916, when Irish republicans seized key locations in Dublin and proclaimed an Irish Republic. The rebellion was crushed, but the survivors united under a reformed Sinn Féin party to campaign for a republic. In the 1918 United Kingdom general election, the party won a clear majority of the constituencies in Ireland; in many seats Sinn Féin candidates did not face meaningful opposition. The Sinn Féin winners did not take their seats in the U.K. parliament, but instead gathered in Dublin on 21 January 1919 to form the first Dáil (legislature) of Ireland. Republicans then established a government, a court system and a police force. At the same time, the Irish Volunteers, who came under the control of the Dáil and became known as the Irish Republican Army, fought against British state forces in the Irish War of Independence.

There were two governments of the 2nd Dáil, which were ministries of Dáil Éireann, the assembly of Dáil Éireann that was the legislature of the Irish Republic, a unilaterally declared state which lasted from 1919 to 1922. The Second Dáil was elected at the 1921 Irish elections on 24 May 1921. The 3rd ministry (26 August 1921 – 9 January 1922) was led by Éamon de Valera as president and lasted 136 days. De Valera resigned as president after the Dáil voted to accept the Anglo-Irish Treaty. The 4th ministry (10 January – 9 September 1922) was led by Arthur Griffith as president. Griffith died in office on 12 August 1922, but a new Dáil ministry was not formed until 9 September 1922. Griffith served 214 days as president, with a further 28 days between his death and the appointment of W. T. Cosgrave as his successor by the Dáil.

The provisional government of Ireland, established under the terms of the Treaty, overlapped with the later period of ministries of Dáil Éireann. The 1st provisional government was led by Michael Collins as Chairman of the Provisional Government from 16 January 1922 until his death on 22 August 1922. On 25 August 1922, W. T. Cosgrave was appointed as his successor, with the other members of the new provisional government appointed on 30 September. The 1st provisional government lasted 218 days from the appointment of Collins until his death, with three days elapsing until the appointment of Cosgrave as his successor.

The president of Dáil Éireann (Irish: Príomh aire [ˌpʲɾʲiːw ˈaɾʲə]), later also president of the Irish Republic, was the leader of the revolutionary Irish Republic of 1919–1922. The office was created in the Dáil Constitution adopted by Dáil Éireann, the parliament of the Republic, at its first meeting in January 1919. This provided that the president was elected by the Dáil as head of a cabinet called the Ministry of Dáil Éireann. During this period, Ireland was deemed by Britain to be part of the United Kingdom of Great Britain and Ireland, but the Irish Republic had made a unilateral Declaration of Independence on 21 January 1919. On 6 December 1922, after the ratification of the Anglo-Irish Treaty, the Irish Free State was recognised by Britain as a sovereign state, and the position of the president of Dáil Éireann was replaced by that of president of the Executive Council of the Irish Free State but, as a Dominion of the British Empire, the British monarch was head of state until the dominion status was rescinded in 1949.
