Calixtus III was Pope from 1455 to 1458. He is remembered for reversing the conviction of Joan of Arc, a French heroine. Imagine being responsible for correcting a major historical injustice. He also promoted a crusade against the Ottoman Turks, who were expanding into Europe. His brief papacy was marked by efforts to strengthen the Church and defend Christendom. His legacy is mixed, but he remains a significant figure in Church history.
