Page "Caligula" Paragraph 43

Mauretania was a client kingdom of Rome ruled by Ptolemy of Mauretania.

Caligula invited Ptolemy to Rome and then had him suddenly executed.

Mauretania was annexed by Caligula and subsequently divided into two provinces, Mauritania Tingitana and Mauretania Caesariensis, separated by the river Malua.

Pliny claims that division was the work of Caligula, but Dio states that in 42 CE an uprising took place, which was subdued by Gaius Suetonius Paulinus and Gnaeus Hosidius Geta, only after which the division took place.

This confusion might mean that Caligula originally made the decision to divide the province, but the implementation was postponed because of the rebellion.

The first known equestrian governor of the two provinces was one Marcus Fadius Celer Flavianus, in office in 44 CE.
