Pope Gregory XII (b. 1326)
Pope Gregory XII (Latin: Gregorius XII; Italian: Gregorio XII; c. 1326 or 1327 – 18 October 1417), born Angelo Corraro, Corario, or Correr, was head of the Catholic Church from 30 November 1406 to 4 July 1415. Reigning during the Western Schism, he was opposed by the Avignon claimant Benedict XIII and the Pisan claimants Alexander V and John XXIII. Gregory XII wanted to unify the Church and voluntarily resigned in 1415 to end the Schism.
