Irish War of Independence
(1919 - 1921)

The Irish War of Independence was a guerrilla campaign mounted against the British government in Ireland by the Irish Republican Army under the proclaimed legitimacy of the First Dáil, the extra-legal Irish parliament created in 1918 by a majority of Irish MPs. It lasted from January 1919 until the truce in July 1921. The war is often referred to as the "Anglo-Irish War" in Britain, the "Tan War" by anti-Treaty republicans and was known contemporarily as "the Troubles", not to be confused with the later conflict in Northern Ireland, which is also referred to as the "the Troubles".
