In 53, Agrippa was forced to give up the tetrarchy of Chalcis but in exchange Claudius made him ruler with the title of king over the territories previously governed by Philip, namely, Batanea, Trachonitis and Gaulonitis, and the kingdom of Lysanias in Abila. The tetrarchy of Chalcis was subsequently in 57 given to his cousin, Aristobulus (). Herod Agrippa celebrated by marrying off his two sisters Mariamne and Drusilla. Flavius Josephus, the Jewish historian, repeats the gossip that Agrippa lived in an incestuous relationship with his sister, Berenice.
