Aristobulus did not directly succeed his father as ruler of the Chalcis. Rather, upon his father's death in 48 AD, the emperor Claudius gave the realm to Aristobulus' first cousin, Herod Agrippa II. When in 52 AD Agrippa was given the territories previously governed by Philip the Tetrarch (also known as Herod Philip II) and Lysanias, Aristobulus was subsequently given Chalcis.[2] He reigned Chalcis until his death in 92 AD[citation needed], when the territory became part of the Roman province Syria.
