Pope Clement III - Definition and Overview

Clement III, né Paulino Scolari (d. March 27, 1191), pope (1187-1191), was elected pope on December 19, 1187, and died in March 1191. He succeeded shortly after his accession in allaying the discords which had prevailed for half a century between the Popes and the citizens of Rome, in virtue of an agreement by which the latter were allowed to elect their magistrates, while the nomination of the governor of the city remained in the hands of the Pope. He incited Henry II of England and Philip Augustus to undertake the Third Crusade, and introduced several minor reforms in ecclesiastical matters.
