After the Battle of Zama (202 BC), Masinissa became famous and was held in high esteem as a friend of the Roman people. For over fifty years he ruled as King of Numidia (lands west of Carthage) until his death in 148 BC. During his reign farming and trade prospered, and the vital pulse of Berber culture quickened. Government institutions were established, evidently having an independent Berber origin, although informed by Punic civil traditions; indeed, Masinissa encouraged the cultural influence of Carthage. "The state, the life of the cites, art, religion, writing—all underwent a rapid process of Punicization." The language used at court was Punic. "He successfully developed agriculture and commerce, and encouraged the spread of Punic civilization."
