From Herod to rebellion
Once the Parthians were victorious, Herod went to Rome to meet Mark Antony, who had obtained the eastern provinces from Octavian in the division of the Roman empire. Through Mark Antony's influence Herod was established as King of Judaea; by this means the Romans hoped to depose Antigonus, the nominee of the Parthians. Advancing against Judaea, Herod conquered the country with the aid of a Roman army. After a siege lasting five months Jerusalem succumbed in 37 BC. Herod then unified the country (by incorporating Samaria), replaced the Council of Elders by an advisory body, and executed forty-five members of the Great Sanhedrin, including many Sadducees who supported the Hasmonean dynasty.
