Kingdom of Capsus Excavations at prehistoric sites in the Gafsa area have yielded artefacts and skeletal remains associated with the Capsian culture. This Mesolithic civilisation has been radiocarbon dated to between 10,000 and 6,000 BCE. The associated ancient population, known as the Snail eaters, are known for their extensive middens of snail shells. They are believed to be the ancestors of the modern Berbers. The city of Capsa belonged to King Jugurtha, who deposited his treasures there. It was captured by Gaius Marius in 106 BC and destroyed, later becoming reestablished under the Punic-style magistracy of sufetes before being granted the status of a Roman colonia. Capsa was an important city of Roman Africa near the Fossatum Africae. Roman cisterns are still evident in the city ruins. The Vandals conquered the Roman city and ruled it until the death of Genseric (477). The Berbers then occupied it, making it the capital of a Romano-Berber kingdom until subjected to Byzantium under Justinian I (527–565). He made Capsa the capital of the province of Byzacena. The Duke of Byzacena resided there. In 540, the Byzantine governor general Solomon built a new city wall, naming the city Justiniana Capsa. The Arab army of Uqba ibn Nafi conquered Gafsa in 688, in spite of resistance from the Berbers. After the Arab conquest, Capsa started to lose importance, replaced by Muslim-founded Kairouan.
