Later, under the strict rules of the peace treaty, Hannibal tried to rebuild Carthage: he enacted measures to help their poorest citizens, he revived their agriculture, and he developed a thriving international trade. Most of Hannibal's measures diminished the power or decreased the wealth of Carthage's most powerful citizens. In 195 B.C., the anti-Carthaginian faction in Rome combined with the oligarchs of Carthage to demand Hannibal's surrender to Rome. Hannibal spent the rest of his life fleeing from Roman envoys, and in 183 B.C., he took his own life rather than surrender to the Roman delegates sent to extradite him.
