The Council of Pisa (Latin: Concilium Pisarum; Italian: Concilio di Pisa, also nicknamed the conciliabolo, "secret meeting", by those who considered it illegitimate) was a controversial council held in 1409. It attempted to end the Western Schism by deposing both Benedict XIII (Avignon) and Gregory XII (Rome) for schism and manifest heresy. The College of Cardinals, composed of members from both the Avignon Obedience and the Roman Obedience, who were recognized by each other and by the Council, then elected a third papal claimant, Alexander V, who lived only a few months. He was succeeded by John XXIII.
