Quick Reference


Pope from 1455. Originally a supporter of Benedict XIII, he induced his successor Clement VIII (antipope, 1423–9) to submit to Martin V. The main efforts of his Papacy were directed to the organization of a crusade against the Turks, a project to which he had been devoted since the fall of Constantinople in 1453, but his plans had little success. He annulled the sentence against Joan of Arc.
