On Easter Monday, April 24 1916, 1,200 members of the Irish Volunteers and Irish Citizen Army mustered in Dublin and declared the formation of the Irish Republic. Marxist and Irish Republican, James Conolly, led the Irish Citizen's Army in hopes that the Easter Rising would touch off a revolution in Ireland that would lead to the establishment of a Workers' Republic, the death of the British Empire, and the beginning of a socialist world revolution.
Over a century later, Ireland is still ruled in the north by what remains of the British Empire, The Republic of Ireland is Bankers' Republic, and hopes for the world revolution are a nostalgic memory... for now.
