Pope Eugene IV
Pope Eugene IV was the head of the Roman Catholic Church from 1431 to 1447. Born as Gabriele Condulmer in Venice, he became a cardinal before his papacy. His reign was marked by efforts to reform the Church and address issues like the Western Schism, a period of division within the Church.
Eugene IV is also known for convening the Council of Florence in 1439, which aimed to reunite the Eastern Orthodox and Roman Catholic Churches. Despite facing challenges, including conflicts with various states and factions, he worked to strengthen the Church's authority and promote peace in Europe.
