This article is about the president of the 1919-1922 Irish Republic. For the head of state of the modern Republic of Ireland see: President of Ireland.

President of the Republic The title given to the head of the Irish ministry or Áireacht in August 1921 by an amendment to the Dáil Constitution, which replaced the previous title, Priomh Áire or President of Dáil Éireann. Unlike the previous offices, which were simply head of government or prime minister, the President of the Republic was explicitly declared to be the Irish Republic's head of state.

Presidents of the Republic

• Eamon de Valera - Sinn Féin (August 1921 to January 1922)

• Arthur Griffith - Pro-Treaty Sinn Féin (January to August 1922)

Following de Valera's resignation, Arthur Griffith was elected to his office, but though he preferred to use the earlier title of President of Dáil Éireann he never actually reverted the constitutional amendments of August 1921. Meanwhile Michael Collins became Chairman of the Provisional Government of the provisional state created in the Anglo-Irish Treaty, 1921.

• W.T. Cosgrave - Pro-Treaty Sinn Fein (August to December 1922)

Following Arthur Griffith's death and Michael Collins's assassination in August 1922, Cosgrave simultaneously held both their offices. In reality all distinction between both offices and indeed both states ceased to exist - by September 1922 it was not even clear when TDs assembled whether they were meeting as the Dail or the Provisional Parliament of the treaty state. Both states themselves and their respective heads of government disappeared with the coming into force in December 1922 of the Irish Free State Constitution Act, 1922 which created the Irish Free State.

The position of President of the modern Republic of Ireland is described in the article President of Ireland.
