Tebessa is a city with deep historical roots, known in antiquity as Theveste. The first mentions of it date back to ancient times when these lands were inhabited by nomadic tribes; however, it formed as a fully-fledged urban centre in the 1st century AD. A decisive moment in its founding history was the establishment of the headquarters of the Legio III Augusta here, transforming a military camp into a thriving settlement.
Key factors in the city's formation included:
- Geography and Strategy: The city is located at a strategically important point at the foot of the Aures Mountains. This allowed for control over the passes between the Mediterranean coast and the Sahara Desert.
- Transport Hub: Vital roads connecting Carthage with the inland territories, which today constitute Algeria, passed through Theveste. This secured the city's role as a major trade crossroads.
- Political Power: Its status as a military base provided the region with security and stable funding, contributing to rapid infrastructure growth.
The early economy of the region was based on rich natural resources. Fertile lands fostered the development of agriculture, particularly grain cultivation and large-scale production of olive oil, which was exported to other parts of the empire. The cultural life of the city quickly became Romanised: majestic temples, forums, and arches were erected here. Many monuments of that era, such as the Temple of Minerva, have survived to this day, testifying to the high status and wealth of the ancient city.
