Regulation of Africa
Without resistance Caesar regulated the affairs of Africa. As Curio had already proposed, the kingdom of Massinissa was broken up. The most eastern portion or region of Sitifis was united with the kingdom of Bocchus king of East Mauretania,(51) and the faithful king Bogud of Tingis was rewarded with considerable gifts.
51. Cf. IV. IV. Reorganization of Numidia
Cirta (Constantine) and the surrounding district, hitherto possessed under the supremacy of Juba by the prince Massinissa and his son Arabion, were conferred on the condottiere Publius Sittius that he might settle his half-Roman bands there;(52) but at the same time this district, as well as by far the largest and most fertile portion of the late Numidian kingdom, were united as "New Africa" with the older province of Africa, and the defence of the country along the coast against the roving tribes of the desert, which the republic had entrusted to a client-king, was imposed by the new ruler on the empire itself.
52. The inscriptions of the region referred to preserve numerous traces of this colonization. The name of the Sittii is there unusually frequent; the African township Milev bears as Roman the name -colonia Sarnensis-(C. I. L. viii. p. 1094) evidently from the Nucerian river-god Sarnus (Sueton. Rhet. 4).
