Frederick II Excommunicated: The Emperor vs the Pope
Frederick II kept promising to go on Crusade. He promised in 1215, again in 1220, again in 1227 — and kept not going. When he finally sailed in 1227 and turned back sick, Pope Gregory IX had had enough and excommunicated him. Then Frederick did something no one expected: he went on Crusade anyway, while still excommunicated. And he succeeded — negotiating a treaty that returned Jerusalem to Christian control without a single battle. The Pope was furious. Frederick had just won the Crusade the Church said he was too sinful to lead.
