In England, King John differed with Innocent over the election of the archbishop of Canterbury, and Innocent placed England under interdict and excommunicated John. Under attack from his barons, John capitulated to Innocent by becoming his vassal, receiving England back as a fief, and paying him a sizable annual tribute.
In France, Innocent forced King Philip Augustus to comply with the church’s moral code by taking back as his queen the woman he had divorced with the consent of the French bishops.
And within the Holy Roman Empire (Germany), Innocent intervened in a civil war between rival candidates for the throne, supporting first one, then the other. In the end Innocent secured the election of his ward, the young Hohenstaufen heir Frederick II, who promised to respect papal rights and to go on a crusade.
