The town grew up around the strategic Byzantine fortress of Tunbudha which, from its hilltop position, controlled the roads into Tunis and Carthage. Equipped with an Arab garrison soon after the Muslim conquest of Carthage by Hasan ibn al-Nu'man at the end of the 7th century, Tunbudha was the site of a rebellion in the 9th century. The local ruler, Mansur al-Tunbudhi, led the junds in revolt against the Aghlabid dynasty.[1]
