The First Punic War (264-241 BCE) between Rome and Carthage was the longest continuous war in the ancient world, which took place both on land, islands and the sea.
The Romans, who earlier had not had much to do with sea battles, made great efforts and created a fleet that finally allowed them to win the war – despite their defeats.
One of the effects of peace was the handing over to Siciliy, which became the first Roman province ( provincia). Soon, Sardinia and Corsica would have a similar fate.
