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. At the start of the first Punic War, Carthage was the dominant power of the Western Mediterranean, with an extensive maritime empire. Rome was a rapidly ascending power in Italy, but it lacked the naval power of Carthage. By the end of the third war, after more than a hundred years and the loss of many hundreds of thousands of soldiers from both sides, Rome had conquered Carthage's empire, completely destroyed the city, and become the most powerful state of the Western Mediterranean.
The Sicilian Wars, or Greco-Punic Wars, were a series of conflicts fought between the Carthaginians and the Greek city-states, led by Syracusans, over control of Sicily and the western Mediterranean between 600 BC and 265 BC.
Carthage's economic success, and its dependence on shipping to conduct most of its trade (for the empire's southern border was surrounded by desert), led to the creation of a powerful navy to discourage both pirates and rival nations. They had inherited their naval strength and experience from their forebearers, the Phoenicians, but had increased it because, unlike the Phoenicians, the Punics did not want to rely on a foreign nation's aid. This, coupled with its success and growing hegemony, brought Carthage into increasing conflict with the Greeks, the other major power contending for control of the central Mediterranean.
The Greeks, like the Phoenicians, were expert sailors who had established thriving colonies throughout the Mediterranean. These two rivals fought their wars on the island of Sicily, which lay close to Carthage. From their earliest days, both the Greeks and Phoenicians had been attracted to the large island, establishing a large number of colonies and trading posts along its coasts. Small battles had been fought between these settlements for centuries.
