Government and the government of the United Kingdom in the period between the ratification of the Treaty and the creation of the Irish Free State. Despite the Pact, the election results started the effective division of Sinn Féin into separate parties. The anti-Treaty TDs then boycotted the new Dáil, even though they had requested, negotiated and approved the terms of the Pact. This boycott gave uncontested control to the pro-treaty members of Sinn Féin, and so enabled W. T. Cosgrave to establish the Second Provisional Government. The First Executive Council of the Irish Free State was appointed on 6 December 1922 on the nomination of this Dáil.
