Martin V was an Italian pope who served as the head of the Catholic Church from 1417 to 1431. He was elected as pope during the Council of Constance, which was convened to resolve the Western Schism, a period of division within the Catholic Church. Martin V worked to reunify the church and restore its authority, and he also focused on reforming the church's administration and finances. His papacy is remembered for its efforts to heal the divisions within the church and strengthen its position in Europe.
