Roger Casement was an Irish diplomat and humanitarian known for his work in exposing human rights abuses in the Congo Free State and Peru. Born in 1864, he initially served in the British Consular Service, where he documented the exploitation and mistreatment of indigenous people by European colonizers. His reports brought international attention to these issues. Later, Casement became involved in Irish nationalism and sought to gain support for Ireland's independence from British rule. He was executed in 1916 for his role in the Easter Rising, a pivotal event in the struggle for Irish independence.
