Pope Innocent V

Pierre de Tarentaise built his name as a preacher and theologian, holding one of the two Dominican chairs at the University of Paris and shaping the Order's curriculum. By 1269 he led the French Dominican province. Pope Gregory X made him Bishop of Ostia and cardinal in 1273, leaning on him as a close adviser. When Gregory died in 1276, the cardinals elected Pierre in the Church's first true conclave—the new rules designed to speed decisions. He took the name Innocent V, brokered peace between Genoa and Charles I of Sicily, and died that June. Leo XIII beatified him in 1898.
