Berber Africa In Roman times, the indigenes of the
Maghreb all belonged to peoples whom the Romans called, loosely east to west, the
Libyae, the
Afri (in what is now
Tunisia and
Algeria, from which the name Africa is probably derived), the
Numidians (eastern
Algeria), and
Mauri (western
Algeria and
Morocco), from which the term "
Moors" was derived. North of the
Atlas Mountains, the land was fertile and well-watered (there is evidence that rainfall was heavier than today and that the desert had not encroached as far north). The Berbers living inside the fertile zone were largely sedentary. In contrast, on the southern fringes existed tribes that led a semi-nomadic existence. They practised
transhumance, living off herds of cattle, sheep, and goats. They spent the summers on the central plateau of Tunisia and the
Aurès of northeast Algeria, where there was good
grazing for the animals. In winter, they lived around the
chotts (pronounced "shots") around
Lake Tritonis, a string of large salt lakes on the desert southern fringes of the Roman province. In winter, this region contained plentiful freshwater in the form of seasonal torrents from the Aurès mountains to the North. The province was populous (c. 1.5 million inhabitants, roughly the same as contemporary
Britain) and was, by 50 BC, the most important source of the City of Rome's grain supply. It was said that
Africa fed the Roman populace for eight months of the year, while
Egypt provided the remaining four months' supply. The province was a land of vast estates (
latifundia) owned by absentee landlords.
Pliny the Elder states that in the time of the emperor
Nero (ruled 54–68), half of all arable land in the province was owned by just six
Roman senators. In 45 BC, Roman
dictator perpetuus Julius Caesar defeated and killed king
Juba I, and annexed his kingdom of
Numidia to the Roman province, calling it Africa Nova ("New Africa"). This, however, dispossessed the ancient pro-Roman dynasty of Numidian kings founded by
Massinissa, whose decision during the
Second Punic War to switch allegiance from
Carthage had been critical to the decisive Roman victory at the
Battle of Zama 158 years earlier. The Numidian king's young son,
Juba II, was brought up and educated at Rome, where he became a close friend of Caesar's grand-nephew
Octavian, who assumed the title of
Augustus after he became sole ruler of the Roman empire in 30 BC. Caesar's settlement was modified in 25 BC by
Augustus. He placed
Juba II on the vacant throne of
Mauretania, and added to it the southern and eastern parts of Africa Nova. Juba thus nominally ruled a vast realm stretching from the
Strait of Gibraltar in the west to
Cyrenaica in the east. Augustus' strategic conception was that Juba's native warriors would provide the Roman province's first line of defence against incursions by the nomadic desert tribes. But Juba proved unequal to the task, not least because the fiercely independent desert tribes refused to recognise his overlordship, despising him as a tool of Roman imperialism.
Conflict with nomadic tribes The most fertile part of
Numidia was retained in the Roman province. This part included
Eastern Algeria and the central Tunisian plateau, land ideal for the cultivation of wheat, for which the Romans had an ever-increasing demand. The region, some 27,000 km2 in area, offered the prospect of doubling the province's grain production. At some point in the first half of Augustus' rule, it appears that the single
legion deployed in the province (the
III Augusta) was stationed at
Theveste (modern Tébessa, Algeria), strategically placed on the western edge of the plateau so as to protect it from incursions from the Aurès mountains. (Later, during Tacfarinas' insurgency, the 3rd legion's base was moved to
Ammaedara – modern Haïdra, Tunisia – right in the centre of the plateau). The road northeast to the provincial capital at
Carthage bisected the plateau. In AD 14, Legio III is recorded as having built a new road southeast to
Tacapae (Gabès) on the coast. Hand-in-hand with the Roman infrastructural expansion came the fencing off of land that was converted from pasture to wheat cultivation. The Romans also pursued a policy of deliberately restricting the transhumance movements of the nomads into the province. Still, the desert tribes' relationships with the Romans were not exclusively hostile. Many tribal nomads are known to have volunteered to serve in the
Roman army, in both the regular
auxilia and irregular native
foederati (allied) units (although conscription was still common at this time, and was another cause of discontent). The army provided the prospect of a well-paid career that gave scope for the tribesmen's martial nature, which was highly regarded by the Romans.
Numidian cavalry (
equites Numidarum or
Maurorum), which had played a prominent role in Roman armies since the
Second Punic War (218–201 BC), were regarded as the best light cavalry in the Roman world. A Numidian cavalryman rode his small but agile and resilient desert mount without bridle, saddle, or stirrups, restraining it by a loose rope round its neck and directing it by leg movements and voice commands. Unarmoured, he was protected by just a small round leather shield. His weaponry consisted of several javelins. Exceptionally fast and manoeuvrable, Numidian cavalry would harass the enemy by hit-and-run attacks, riding up and loosing volleys of javelins, then scattering and retreating faster than any opposing cavalry could pursue. They were superbly suited to scouting, harassment, ambush, and pursuit. Numidian foot soldiers were also predominantly light infantry, relying on speed and manoeuvrability. However, both Numidian foot and mounted warriors were vulnerable in close-order combat with Roman troops, who mainly wore metal armour. ==Early life==
