Tom Clarke, Irish rebel (b. 1858)
Thomas James Clarke (Irish: Tomás Séamus Ó Cléirigh; 11 March 1858 – 3 May 1916) was an Irish republican and a leader of the Irish Republican Brotherhood. Clarke was arguably the person most responsible for the 1916 Easter Rising. A proponent of armed struggle against British rule in Ireland for most of his life, Clarke spent 15 years in English prisons prior to his role in the Easter Rising, and was executed by firing squad after it was defeated.
