1911 Encyclopædia Britannica/Innocent/Innocent III (Antipope)
Innocent III. (Lando da Sezza), antipope (1179–1180), sprang from a noble Lombard family. Opponents of Alexander III. tried to make him pope in September 1179. Alexander, however, bribed his partisans to give him up, and imprisoned him in the cloister of La Cava in January 1180.
