While the war with Rome was being played out, the Carthaginian general Hanno, who was one of several Carthaginian Hannos known as "the great", was leading a series of campaigns which greatly increased the area of Africa controlled by Carthage. He extended its control to Theveste (modern Tébessa, Algeria) south-west of their capital. Hanno was rigorous in squeezing taxes out of the newly conquered territory to pay for both the war with Rome and his campaigns. Half of all agricultural output was taken as war tax, and the tribute previously due from towns and cities was doubled. These exactions were harshly enforced, causing extreme hardship in many areas.
