Hannibal of Carthage, who lived around 200 BCE, is considered one of the three top military leaders in history. He was the scourge of the peoples who lived in the area, especially the Romans, with his most famous achievement being marching an army, including war elephants, from Iberia (Spain) over the Alps into northern Italy. Hannibal endured his only defeat at the battle of Zama, on his very own land. After this loss, Carthage signed a denigrating peace agreement which took away most of the local people's holdings. The Romans allowed Hannibal to return to Carthage and did not imprison him. Seven years later, when the Romans suspected he was planning another rebellion, did he agree to go into exile to prevent another war. He became the military adviser of Antiochus III, the Romans' great foe, but both his and Antiochus navies were badly beaten by the Roman navy. As a condition for peace, the Romans demanded that Hannibal again go into exile. He succeeded in escaping, but the Romans chased him down, and he decided to commit suicide rather than be captured. He drank the poison he kept in his ring, and, according to legend, even laughed while he was killing himself.
