Eugene IV

Pope Eugene IV (Latin: Eugenius IV; 1383 – 23 February 1447), born Gabriele Condulmer, was Pope from 1431 to his death. He was noted for his strong piety and condemnation of slavery.

In 2012, the Assassin Shaun Hastings kept a portrait of Eugene at his work station while researching the Renaissance Papacy.
