Second Punic War, 218–201 BC

In 219 BC a Carthaginian army under Hannibal besieged, captured and sacked Saguntum and in spring 218 BC Rome declared war on Carthage. There were three main military theatres in the war: Italy, where Hannibal defeated the Roman legions repeatedly, with occasional subsidiary campaigns in Sicily, Sardinia and Greece; Iberia, where Hasdrubal, a younger brother of Hannibal, defended the Carthaginian colonial cities with mixed success until moving into Italy; and Africa, where the war was decided.
