Peter of Castile

Peter became King of Castile and León in 1350, at fifteen, and ruled for nineteen years. His reign split opinion so sharply that history handed him opposing labels: some called him the Cruel, others the Just. His treatment of the clergy grew severe enough that Pope Urban V excommunicated him. He was the last king of the main branch of the House of Ivrea. On 23 March 1369, his rule ended — he died at thirty-four.
