Archaeological evidence of prehistoric human settlement on the island of Sardinia is present in the form of nuraghes and other prehistoric monuments, which dot the land. The recorded history of Sardinia begins with its contacts with the various people who sought to dominate western Mediterranean trade in classical antiquity: Phoenicians, Punics and Romans. Initially under the political and economic alliance with the Phoenician cities, it was partly conquered by Carthage in the late 6th century BC and then entirely by Rome after the First Punic War. The island was included for centuries in the Roman province of Sardinia and Corsica, which would be incorporated into the diocese of Italia suburbicaria in 3rd and 7th centuries.

The nuraghe, or nurhag, is the main type of ancient megalithic edifice found in Sardinia, Italy, developed during the Nuragic Age between 1900 and 730 BC. Today it has come to be the symbol of Sardinia and its distinctive culture known as the Nuragic civilization. More than 7,000 nuraghes have been found, though archeologists believe that originally there were more than 10,000.
