Martin V was a pope who served from 1417 to 1431. He was born as Oddone Colonna in 1368 and became the first pope elected after the Western Schism, a period of division in the Catholic Church where multiple claimants to the papacy existed. His election helped to restore unity within the Church. During his papacy, Martin V focused on rebuilding the Church's authority and addressing various issues, including the need for reform. He convened the Council of Constance, which aimed to resolve the schism and improve Church governance. His leadership marked a significant turning point in the history of the papacy.
