description: "Seamus Costello was an Irish republican socialist, paramilitary leader, and elected politician. Born in Bray, County Wicklow, he rose to prominence in the republican movement during the Irish Republican Army's Border Campaign of the late 1950s and subsequently became one of the most significant, if divisive, figures in Irish republican politics. He is best remembered as the founder of the Irish Republican Socialist Party (IRSP) and its paramilitary wing, the Irish National Liberation Army (INLA). He remains the only leader of an Irish political party to have been assassinated."
