Michael Collins (Irish: Mícheál Ó Coileáin;[2] 16 October 1890 – 22 August 1922) was an Irish revolutionary, soldier and politician who was a leading figure in the early-20th century struggle for Irish independence. He was Chairman of the Provisional Government of the Irish Free State from January 1922 and commander-in-chief of the National Army from July until his death in an ambush in August 1922, during the Civil War. Collins was born in Woodfield, County Cork, the youngest of eight children. He moved to London in 1906 to become a clerk in the Post Office Savings Bank at Blythe House. He was a member of the London GAA, through which he became associated with the Irish Republican Brotherhood and the Gaelic League. He returned to Ireland in January 1916 and fought in the Easter Rising. He was taken prisoner and held in the Frongoch internment camp as a prisoner of war, but he was released in December 1916. Collins subsequently rose through the ranks of the Irish Volunteers and Sinn Féin. He was elected as a Teachta Dála for South Cork in 1918 and appointed Minister for Finance in the First Dáil. He was present when the Dáil convened on 21 January 1919 and declared the independence of the Irish Republic. In the ensuing War of Independence, he was Director of Organisation and Adjutant General for the Irish Volunteers, and Director of Intelligence of the Irish Republican Army. He gained fame as a guerrilla warfare strategist, planning and directing many successful attacks on British forces, such as the "Bloody Sunday" assassinations of key British intelligence agents in November 1920. After the July 1921 ceasefire, Collins was one of five plenipotentiaries sent by the Dáil cabinet led by Éamon de Valera to negotiate peace terms in London. The resulting Anglo-Irish Treaty, signed in December 1921, established the Irish Free State but depended on an oath of allegiance to the Crown. This was the clause in the treaty de Valera and other republican leaders found hardest to accept. Collins viewed the treaty as offering "the freedom to achieve freedom", and persuaded a majority in the Dáil to ratify the treaty. A provisional government was formed under his chairmanship in early 1922 but was soon disrupted by the Irish Civil War, in which Collins was commander-in-chief of the National Army. He was shot and killed in an ambush by anti-Treaty forces on 22 August 1922.
