Sixth Crusade
While he was in Rome on the business of the order, Pope Honorius III created him cardinal, on 8 January 1219, and later charged him as Papal legate with two important missions: one in France (1220–23), to suppress the Albigenses; the other in Germany (1224–26), to promote the crusade which Emperor Frederick II had vowed to undertake (the eventual Sixth Crusade).
