A hanged man was never more popular. One hundred years ago, the British government executed Roger Casement for his participation in a rebellion in Ireland, the Easter Rising of 1916. This year, schoolchildren and tourists by the thousands have visited Casement’s gravesite in Dublin. It is part of a centennial pilgrimage in honour of the Rising, the pivotal event in modern Irish history, marked by headstones, prisons, and rebel redoubts now hard to imagine in jostling traffic. As the First World War raged across Europe, Irish men and women joined the Rising in an attempt to break from a United Kingdom that had bound Ireland for 115 years. In fighting to establish an Irish republic, they battled not just the British government; they also faced the prospect of a civil war against Irish Protestant unionists in the northern province of Ulster who had already spent three years arming themselves against the prospect of political domination by Ireland’s Catholic majority. In the aftermath of the Rising, the British government executed 16 rebel leaders, including Casement. He was hanged and buried on August 3 in the yard of Pentonville Prison in London, England, a land and sea away from his current resting place.
