Innocent II spent most of his thirteen years as pope fighting for supremacy against Antipope Anacletus II, who by any legal standard had the appropriate authority to claim the papacy. Anacletus was elected by the usual means, while Innocent was elected by a group of eight men selected by Honorius II, his predecessor. The dispute was only resolved by Anacletus' death in 1138; the rest of Innocent's life was spent mostly clearing up this dispute.
