Celestine III

Celestine III leads the Catholic Church as supreme pontiff from Rome during the Third Crusade era. He commands spiritual authority over Christian monarchs, including King Richard the Lionheart and Princess Joanna, dictating moral boundaries on issues like interfaith marriage. His decrees enforce religious orthodoxy, placing divine law above royal prerogative and blocking unions with Muslims to safeguard doctrinal purity. Unyielding in faith matters, he anchors the era's crusading tensions between temporal ambition and ecclesiastical control.
