The members of the 2nd Dáil first met on 16 August 1921. The outgoing Ministry of Dáil Éireann did not resign immediately. On 26 August 1921, Éamon de Valera resigned as President. De Valera was then proposed by Seán Mac Eoin and seconded by Richard Mulcahy to the position of President of the Irish Republic and approved unanimously. This was a change of title, suggesting that de Valera was now considered as the head of state of the Irish Republic, rather than only its head of government. De Valera then proposed the members of the 3rd Ministry of the Irish Republic, which were approved by the Dáil.

4th Ministry
On 7 January 1922, the Anglo-Irish Treaty was approved by Dáil Éireann in a vote of 64 to 57. Among those voting against were President de Valera. On 10 January, he resigned as President. He was then proposed by Kathleen Clarke and seconded by Liam Mellowes for the position of president. This motion was defeated with 58 votes in favour to 60 against. On 10 January, Arthur Griffith was proposed as President of Dáil Éireann by Michael Collins and seconded by Eoin O'Duffy. While the vote was to take place, de Valera and his supporters rose and left the Dáil chamber. Griffith was then approved unanimously by those members remaining in the Dáil. The members of the 4th Ministry were then proposed by Griffith and approved by the Dáil. Under the terms of the Treaty another cabinet, the Provisional Government, was also established on 16 January, with Michael Collins as Chairman of the Provisional Government of the Irish Free State. The 4th Ministry therefore held office in parallel with the 1st Provisional Government. In August, Griffith died of natural causes and Collins was killed in action. The remaining members of the Ministry remained in office until the Third Dáil elected a new Ministry on 9 September under W. T. Cosgrave. Cosgrave had also been named as Chairman of the Provisional Government on the death of Collins in August, and from 9 September the personnel of the two cabinets were identical. Both cabinets were replaced by the Executive Council of the Irish Free State on 6 December 1922.

1st Provisional Government
The 1st Provisional Government was the Provisional Government that held office from 16 January – 30 August 1922. The Provisional Government was established under the terms of the Anglo-Irish Treaty as an interim administration that would govern Ireland until the establishment of the Irish Free State in December. Its members were nominated at a meeting of "the members elected to sit in the House of Commons of Southern Ireland", on 14 January, and they took up office two days later. The British government formally transferred power to the cabinet on 1 April. Headed by Michael Collins as Chairman, its membership consisted solely of members of the pro-Treaty wing of Sinn Féin. At the time the Provisional Government was established there was a pre-existing executive administration in the form of the 4th Ministry of the Irish Republic, but that cabinet was not recognised by the British government. The 4th Ministry had come to office on 10 January, just six days before the Provisional Government, and continued in office after the latter's establishment. There were thus two parallel administrations, with an overlapping membership. After the Civil War began on 29 June four members of the cabinet were seconded for military service and substitutes were appointed to temporarily take their places as acting ministers. Two new members, Michael Hayes and Ernest Blythe, began serving as acting ministers on 17 July and were added to the cabinet as permanent members on 27 July. Collins was killed in action on 22 August and so the cabinet met and elected Cosgrave as chairman on 25 August. Five days later the entire cabinet was reconstituted as the 2nd Provisional Government. The Third Dáil met on 9 September and appointed the 5th Ministry, with its membership identical to that of the newly constituted Provisional Government. This cabinet, with its dual identities, continued as the sole Government, and was superseded on 6 December 1922 by the formation of the 1st Executive Council of the Irish Free State.
