The Mercenary War (240 BC – 238 BC), also called the Libyan War and the Truceless War by Polybius, was an uprising of mercenary armies formerly employed by Carthage, backed by Libyan settlements revolting against Carthaginian control.The war began as a dispute over the payment of money owed the mercenaries between the mercenary armies who fought the First Punic War on Carthage's behalf, and a destitute Carthage, which had lost most of its wealth due to the indemnities imposed by Rome as part of the peace treaty.
