Pope Eugene IV (Latin: Eugenius IV), born Gabriele Condulmer, was Pope from 3 March 1431 to his death in 1447. He is the last pope to take the name "Eugene" upon his election.
Condulmer was quickly elected to succeed Martin V in the papal conclave of 1431. He was crowned as Eugene IV at St. Peter's Basilica on 11 March 1431. By a written agreement made before his election he pledged to distribute to the cardinals one-half of all the revenues of the Church and promised to consult with them on all questions of importance, both spiritual and temporal. He is described as tall, thin, with a winning countenance, although many of his troubles were owing to his own want of tact, which alienated parties from him. Upon assuming the papal chair, Eugene IV took violent measures against the numerous Colonna relatives of his predecessor Martin V, who had rewarded them with castles and lands. This at once involved him in a serious contest with the powerful house of Colonna that nominally supported the local rights of Rome against the interests of the Papacy. A truce was soon arranged.
Eugene died in Rome on 23 February 1447 and was buried at Saint Peter's by the tomb of Pope Eugene III.
