Pope Pius IV (Italian: Pio IV; 31 March 1499 – 9 December 1565), born Giovanni Angelo Medici, was head of the Catholic Church and ruler of the Papal States from 25 December 1559 to his death in 1565. Born in Milan, his family considered itself a branch of the House of Medici and used the same coat of arms.
