 In 1166, "prior Arbanensis" Andrea and "episcopis Arbanensis" Lazarus participated in a ceremony held in Kotor (then under the Serbian Grand Principality).A year later in 1167, Pope Alexander III, in a letter directed to Lazarus, congratulates him for returning his bishopric to Catholic faith and invites him to acknowledge the archbishop of Ragusa as his superior.After some resistance from local officials, the bishopric of Arbanon was put under the direct dependence of the Pope, as documented in a Papal letter dated in 1188.
