The Punic Wars were a series of three wars fought between Rome and Carthage from 264 BC to 146 BC. At the time, they were probably the largest wars that had ever taken place. The term Punic comes from the Latin word Punicus (or Poenicus), meaning "Carthaginian", with reference to the Carthaginians' Phoenician ancestry. The main cause of the Punic Wars was the conflicts of interest between the existing Carthaginian Empire and the expanding Roman Republic. The Romans were initially interested in expansion via Sicily (which at that time was a cultural melting pot), part of which lay under Carthaginian control.
THE I PUNIC WAR- the First Punic War (264–241 BC) was fought partly on land in Sicily and Africa, but was largely a naval war. It began as a local conflict in Sicily between Hiero II of Syracuse and the Mamertines of Messina. The Mamertines enlisted the aid of the Carthaginian navy, and then subsequently betrayed them by entreating the Roman Senate for aid against Carthage. The Romans sent a garrison to secure Messina, so the outraged Carthaginians then lent aid to Syracuse. With the two powers now embroiled in the conflict, tensions quickly escalated into a full-scale war between Carthage and Rome for the control of Sicily. After a harsh defeat at the Battle of Agrigentum in 262 BC, the Carthaginian leadership resolved to avoid further direct land-based engagements with the powerful Roman legions, and concentrate on the sea where they believed Carthage's large navy had the advantage. Initially the Carthaginian navy prevailed. In 260 BC they defeated the fledgling Roman navy at the Battle of the Lipari Islands. Rome responded by drastically expanding its navy in a very short time. Within two months the Romans had a fleet of over one hundred warships. Because they knew that they could not defeat the Carthaginians in the traditional tactics of ramming and sinking enemy ships, the Romans added the corvus, an assault bridge,
