When did the the Great Revolt start?
First Jewish–Roman War
The years 7–26 were relatively calm, but after 37 the province again began to be a source of trouble for Emperor Caligula. The cause of tensions in the east of the Empire was complicated, involving the spread of Greek culture, Roman Law and the rights of Jews in the empire. Caligula did not trust the prefect of Egypt, Aulus Avilius Flaccus. Flaccus had been loyal to Tiberius, had conspired against Caligula's mother and had connections with Egyptian separatists.[10] In 38, Caligula sent Agrippa to Alexandria unannounced to check on Flaccus.[11] According to Philo, the visit was met with jeers from the Greek population, who saw Agrippa as the king of the Jews.[12] Flaccus tried to placate both the Greek population and Caligula by having statues of the emperor placed in Jewish synagogues.[13][14][15][16]
