Julianus ben Sabar (also known as Julian or Julianus ben Sahir and Latinized as Iulianus Sabarides) was a messianic leader of the Samaritans, who led a failed revolt against Byzantium during the early 6th century. In 529 Julianus led a revolt against the Byzantine Empire ruled by Justinian I, because of legislation outlawing the Samaritan religion according to Procopius, though Cyril of Scythopolis claimed it was because of tension with Christians. Julianus' revolt has been compared to the Bar Kokhba Revolt 400 years prior.
