Honorius III was pope from 1216 to 1227, and also spent much of his time trying to launch a Crusade to recapture the Holy Land. His hopes rested on his close relationship with Frederick II, the Holy Roman Emperor. Frederick had promised to go, but never really got around to it, even after marrying the woman who stood to inherit the Kingdom of Jerusalem.

Honorius' other big legacies are his approval of the Dominicans and Franciscans.
