Born in 1864 in Dublin, Casement was knighted for his services to the British consulate. He campaigned tirelessly to expose the cruelty inflicted on native workers in the Belgian Congo in 1904, and again in Brazil from 1911-1912, causing an international sensation with his reportage. Casement had become a member of the Gaelic League in 1904, beginning at that time to write nationalist articles under the pseudonym ‘Seán Bhean Bhocht’. He retired from the British consular service in 1913, after which he joined the Irish Volunteers. Casement was despatched to Germany on account of his experience to raise an Irish Brigade from Irish prisoners of war. He was captured in Kerry in 1916 on Good Friday having returned to Ireland in a German U-Boat. Casement was imprisoned in Pentonville Gaol in London, where he was tried on charges of High Treason. He was hanged on 3 August 1916, the only leader of the Rising to be executed outside of Ireland.
