The Phoenicians arrived around 1000 BC, founding Cagliari (Karalis, ca 800 BC) and other emporia; Tharros (near Oristano) and Nora (near Pula, Cagliari province) are a must-see for the archeology-minded tourist.
Sardinia was contended during the First Punic War between Carthage and Rome but went finally to the latter. Rome had often trouble with the rebellious locals, but managed quite a large income out of grain and metal mining.
With the fall of the Roman Empire, heavy raiding of the coastal areas by pirates forced the population to the hinterland; Sassari for instance was founded by refugees from Porto Torres. The four Kingdoms of Calaris (Cagliari), Arborea (Oristano), Torres (Sassari) e Gallura (Olbia-Tempio Pausania) sprang forth during the Middle Ages, but were rapidly colonized (except for the Oristano area) by Pisa and Genoa; in particular the Pisans (the famous Conte Ugolino della Gherardesca of Dante’s Inferno and his family) held between 1200 and 1350 the southernmost part of the island, deriving a large income out of the silver mines near Iglesias, which they themselves founded. Spain then seized the whole of Sardinia by the end of the 14th century, and for nearly 400 years the island would be a Spanish territory.
With the rise of the House of Savoy, to which the island had been ceded by the Spanish Crown in 1720, the constitution of the Sardinia-Piedmont realm was the starting point for the unification of all the Italian peninsula. When this was achieved, Sardinia was once again left to its own devices, except for the exploitation of its large mineral resources. Fascism saw important work (in particular the reduction of marshy areas), and in 1948, given the unique socio-political context of the island, Sardinia received the status of autonomous region which it still retains to the present day. With the end of the exploitation of the mines, but with the fast growth of the tourist industry (especially in the Costa Smeralda [“Emerald Coast”] area), Sardinia is slowly converting itself into a popular tourist destination, while traditional stock-herding (in particular sheep) is still a frequent sight.
