Irish Free State replaces Irish Republic
Background
The Easter Rising of 1916 and its aftermath caused a profound shift in public opinion towards the republican cause in Ireland. In the December 1918 General Election, the republican Sinn Féin party won a large majority of the Irish seats in the British parliament: 73 of the 105 constituencies returned Sinn Féin members (25 uncontested). The elected Sinn Féin MPs, rather than take their seats at Westminster, set up their own assembly, known as Dáil Éireann (Assembly of Ireland). It affirmed the formation of an Irish Republic and passed a Declaration of Independence. The subsequent War of Independence, fought between the Irish Republican Army (IRA) and British security forces, continued until July 1921 when a truce came into force. By this time the Parliament of Northern Ireland had opened, established under the Government of Ireland Act 1920, presenting the republican movement with a fait accompli and guaranteeing the British presence in Ireland. In October negotiations opened in London between members of the British government and members of the Dáil, culminating in the signing of the Anglo-Irish Treaty on 6 December 1921.The Treaty allowed for the creation of a separate state to be known as the Irish Free State, with dominion status, within the then British Empire—a status equivalent to Canada. The Parliament of Northern Ireland could, by presenting an address to the king, opt not to be included in the Free State, in which case a Boundary Commission would be established to determine where the boundary between them should lie. Members of the parliament of the Free State would be required to take an oath of allegiance to the king, albeit a modification of the oath taken in other dominions.The Dáil ratified the Treaty on 7 January 1922, causing a split in the republican movement. A Provisional Government was formed, with Michael Collins as chairman.
