24 April 1916

On 24 April 1916, Patrick Pearse stood outside the General Post Office in Dublin and read a proclamation announcing the establishment of an Irish republic under a provisional government. Among the seven signatories of the proclamation was James Connolly, head of the para-military Irish Citizen Army, who had earlier led a successful occupation of the building. Elsewhere in Dublin, armed men had taken over key points such as the Four Courts, the College of Surgeons overlooking St Stephen's Green, and Boland's Mills. It was Easter Monday, and there were few people in the centre of Dublin to witness the rising. Many army officers had gone to the Fairyhouse races.

Almost all the revolutionary leaders were members of the secret Irish Republican Brotherhood. The outbreak of war had persuaded them that in England's difficulties lay Ireland's opportunity. As earlier rebels had looked to France for help, they now turned to Germany, which promised to send arms. In addition to the small Irish Citizen Army, formed in 1913 to defend workers against police harassment, there were thousands of Irish Volunteers, a body formed in response to the Ulster Volunteer Force. Like the UVF, the Volunteers carried out a successful gun-running exploit, landing arms at Howth, near Dublin, a few days before war was declared.
