Emperor Frederick II Is Excommunicated

Holy Roman Emperor Frederick II was temporarily excommunicated by Pope Gregory IX on September 29, 1227, due to the emperor's failure to conduct a crusade against the Muslims, one of the conditions of his coronation.

Born in Lesi, Italy, on December 26, 1194, Frederick succeeded to his throne via a rather troubled path. He had been born into a protracted family feud over who would rule the sprawling Holy Roman Empire, which had historically been centered in Germany and central Europe but also had extensive territorial possessions and ambitions throughout Italy. The medieval papacy, which was strong in spiritual authority but often weak in temporal authority outside the religious center of Rome, was understandably nervous about the Holy Roman Empire's power in Italy. During Frederick's youth he faced a lengthy struggle for the throne with the deposed former emperor, Otto IV. This conflict attracted the attention of the papacy for various reasons, including Frederick's control over the kingdom of Sicily to Rome's south. The papacy supported Frederick, who eventually defeated Otto, and Frederick was crowned Holy Roman Emperor by Pope Honorius III on November 22, 1220. Upon this occasion, Frederick promised to launch a crusade in the Middle East in order to free the Holy Land from the “infidel” Muslims.

Frederick was delayed from carrying out his promise due to the continuing strife in various parts of his empire, including Sicily. He finally launched his crusade in September 1227 but had to turn back only three days later due to an outbreak of illness among his men. Honorius had died, but the new pope Gregory IX was irritated by this breach of a commitment, especially since it followed several previous delays by Frederick in launching the crusade. Therefore, Gregory excommunicated Frederick, a severe punishment in that day when church sanction was an important part of any monarch's authority in the Western world. Frederick began his crusade once again in June 1228. He successfully negotiated with the sultan of Egypt for control of the holy city of Jerusalem and nearby lands and was crowned king of Jerusalem on March 18, 1229. After this success, Frederick's excommunication was lifted in 1230.
