The Easter Rising of 1916 was a revolt against the British, led by Padraig Pearse and Tom Clarke, backed by the Irish Volunteers and members of the Irish Citizen Army. They took control of the General Post Office in Dublin, along with other key positions. Fighting continued for five days until the British put down the rebels.
Fifteen of the leaders were subsequently tried and executed. Although the rebellion had not been popular with the majority of Irish people, the executions caused widespread antagonism towards the British. It marked the beginning of the end of British rule in Ireland.
