Their son Ptolemy was assassinated by Caligula during a trip to Rome in AD40. Rome proclaimed the annexation of Mauretania, which was resisted by Ptolemy's former slave Aedemon and by Berber leaders such as Sabalus. Caligula himself was murdered before Rome's response could be made, but his successor Claudius sent legions under Gn. Hosidius Geta and G. Suetonius Paulinus to complete the conquest. By 44, most resistance had been ended and the former kingdom was divided into two Roman provinces, one governed from Tingis (present-day Tangiers) and another governed from Caesarea. Mauretania Caesariensis extended along what is now the Algerian coast and included most of the hinterland as far as the Atlas Mountains.
