Irish Free State

Republic of Ireland

The Irish Free State (1922–1937) was the state comprising the twenty-six of  Ireland's thirty-two counties that were separated from the United Kingdom of Great Britain and Ireland under the Anglo-Irish Treaty signed by British and Irish Republic representatives in London on December 6, 1921. The Irish Free State came into being on December 6, 1922, replacing two nominally co-existing but parallel states: the de jure Southern Ireland, which had been created by the Government of Ireland Act 1920 and which from January 1922 had been governed by a Provisional Government under Michael Collins; and the de facto Irish Republic under the President of Dáil Éireann, Arthur Griffith, which had been created by Dáil Éireann in 1919. (In August 1922, both states in effect merged with the deaths of their leaders; both posts came to be held simultaneously by W. T. Cosgrave.)
