Reigned from November 30, 1406 to July 4, 1415. Born c.1327in Venice, Italy as Angelo Corrario or Angelo Correr; died on October 18, 1417 at Recanati, Italy. He was elected after swearing to resign, in order to end the Great Schism, if Benedict XIII, the Avignon pope, would do likewise. When the latter hesitated, Gregory refused to resign, and the cardinals at the Council of Pisa elected Alexander V to replace both. Gregory, who was the legal pope, pronounced both schismatics. At the 14th session of the Council of Constance which had been called by anti-pope Baldassare Cossa, Gregory submitted his resignation by proxy. It was accepted on July 4, 1415, and he was made cardinal-bishop of Porto.
