Bocchus II was a king of Mauretania in the 1st century BC. He was the son of Mastanesosus, who died in 49 BC, upon which Bocchus inherited the throne. Biography He was surely the son of Mastanesosus, king of Mauretania. His father was identified from the Latin legends of the coins that give the exact lineage Rex Bocchus Sosi f or Sos fi and cannot be read other than "King Bocchus son of Sosus". By the De Bello Africo it is known that in 49 BC, the kingdom of Sosus, which had also been that of the earlier Bocchus I, had been divided between Bocchus II and Bogud, who were brothers. Bocchus II ruled over the eastern part of Mauretania and had Iol as capital and his brother Bogud ruled over the western part of Mauretania and had Volubilis as capital. The only known things about his rule were three events: his relations with Sittius, his part in the war against Juba I and the Pompeians, and the annexation of Western Mauretania. He was recognized as king by the Caesarean Senate in 49 BC, but he was previously hostile to Juba and it is unknown when exactly his reign began. It is certain that by this time, him and his brother Bogud, would plead in favor of Caesar against the Pompeians and their ally Juba I, king of Numidia. Conquest of Numidia During the Roman civil war of 49–45 BC, Bocchus and Sittius invaded Numidia, overthrowing Massinissa II, whose kingdom was easily conquered, and seized Cirta within a few days, the capital of the kingdom of Juba I, who was thus obliged to abandon the idea of joining Metellus Scipio against Caesar. Bocchus' actions stopped there, but Sittius continued the fight, beating Saburra, the lieutenant of Juba, capturing Faustus, Sylla, and Afranius, leading his fleet to Hippo Regius, where he caught Metellus Scipio's ship rushing. At the end of the war, Caesar bestowed upon Bocchus part of the territory of Masinissa II, Juba's ally, which was recovered by Massinissa's son Arabio after Caesar's murder. The kingdom of Mauretania thus extended to Ampsaga. The rest of the kingdom of Massinissa II, the region near the sea north of Cirta and the territory of Cirta, which had belonged to Juba, were given to Sittius. Annexation of Western Mauretania and death Dio Cassius says that Bocchus sent his sons to support Sextus Pompeius
