Thus, the Samaritans rebelled again under the rule of emperor Anastasius I, reoccupying Mount Gerizim, which was subsequently reconquered by the Byzantine governor of Edessa, Procopius. A third Samaritan revolt which took place under the leadership of Julianus ben Sabar in 529 was perhaps the most violent. Neapolis' bishop Ammonas was murdered and the city's priests were hacked into pieces and then burned together with the relics of saints. The forces of Emperor Justinian I were sent in to quell the revolt, which ended with the slaughter of the majority of the Samaritan population in the city.
