The expedition failed and this caused a political revolution in Carthage, from which Mago emerged. He launched another expedition against the island, in 509 BCE, after the Sardinians attacked the Phoenicians' coastal cities. According to Piero Bartoloni, it was Carthage that attacked the Phoenician cities in the coasts, rather than the natives who lived in those cities with the Phoenicians, for the Phoenician cities destroyed, such as Sulcis or Monte Sirai, he postulated as being inhabited mostly by native Sardinians. The Carthaginians, after a number of military campaigns in which Mago died and was replaced by his brother Hamilcar, overcame the Sardinians and conquered coastal Sardinia, the Iglesiente with its mines and the southern plains. The Nuragic culture may have survived in the mountainous interior of the island. In 238 BCE the Carthaginians, as a result of their defeat by the Romans in the first Punic War, surrendered Sardinia to Rome. Sardinia together with Corsica became a Roman province ("Corsica et Sardinia"), however the Greek geographer Strabo confirms the survival, in the interior of the island, of Nuragic culture even in Imperial times. Religion had a strong role in Nuragic society, which has led scholars to the hypothesis that the Nuragic civilization was a theocracy. Some Nuraghe bronzes clearly portray the figures of chief-kings, recognizable by their wearing a cloak and carrying a staff with bosses. Also depicted are other classes, including miners, artisans, musicians, wrestlers (the latter similar to those of the Minoan civilizations) and many fighting men, which has led scholars to think of a warlike society, with precise military divisions (archers, infantrymen). Different uniforms could belong to different cantons or clans, or to different military units. The priestly role may have been fulfilled by women. Some small bronzes also give clues about Nuragic personal care and fashion. Women generally had long hair; men sported two long braids on each side of the face, while their head hair was cut very short or else covered by a leather cap. The Nuragic civilization was probably based on clans, each led by a chief, who resided in the complex nuraghe, with common people living in the nearby villages of stone roundhouses with straw roofs, similar to the modern "pinnettas" of the Barbagia shepherds.
