Geographically, Biskra Province is arid, but oases and rivers can be found, such as the Djedi River which flows through the province. The mountainous Aurès region also extends into the province.
The Biskra area has been inhabited since at least the 3rd millennium BC, when the Gaetuli, an ancient Berber tribe, arrived in North Africa. They settled in the Aurès region, where they posed problems to Roman infiltration in the 3rd century BC as they were stellar horsemen and became dreaded in combat. Eventually, Roman politician Gaius Marius negotiated exploration of the South against concessions of agricultural land around Cirta and Setifis (at the time under Roman rule), and dispersed them and diminished their strength.
Roman occupation
The Biskra area experienced many violent wars during Roman colonization, including the resistance war led by the Berber leader Tacfarinas, followed by his successor, the militant Jugurtha "Youghorta". With the help of the inhabitants of the city of Biskra, who provided human and material support, Jugurtha destroyed the Roman army at the end of the so-called Numidia region.
The Romans also established the city of Tolga and during their rule in the second century A.D, Syrian archers guarding the town of El Kantara were thought to have planted the first date palm grove in the region.
