“ Honorius III. (Cencio Savelli) , pope from the 18th of July 1216 to the 18th of March 1227, a highly-educated and pious Roman, successively canon of Sta Maria Maggiore, cardinal-deacon of Sta Lucia in Silice, vice-chancellor, chamberlain and cardinal-priest of Sti Giovanni e Paolo, was the successor of Innocent III. He made peace with Frederick II., in accordance with which the emperor was crowned with his wife Constance in St Peter’s on the 22nd of November 1220, and swore to accord full liberty to the church and to undertake a crusade. ”

“ Honorius was eager to carry out the decrees of the Lateran Council of 1215 against the Albigenses and to further the crusade proclaimed by his predecessor. He crowned Peter of Courtenay emperor of Byzantium in April 1217; espoused the cause of the young Henry III. of England against the barons; accepted the Isle of Man as a perpetual fief ”

“ He was the first pope to employ the great banking houses in northern Italy for the collection of papal dues. He died at Rome and was succeeded by Nicholas IV.
