Proclamation of the Irish Republic

The Proclamation of the Republic (Irish: Forógra na Poblachta), also known as the 1916 Proclamation or the Easter Proclamation, was a document issued by the Irish Volunteers and the Irish Citizen Army during the Easter Rising in Ireland, which began on 24 April 1916. In it, the Military Council of the Irish Republican Brotherhood, writing as the "Provisional Government of the Irish Republic," proclaimed Ireland's independence from the United Kingdom.
