The city's name comes from its distance to Cagliari, and from the passage there of St. Helena, mother of emperor Constantine. The first traces of human presence in Quartu are from the Prenuragic, Nuragic and Phoenician period, as attested by findings in Cepola, Geremeas, Is Mortorius and Separassiu localities. Roman findings were found near Sant’Andrea villa, a graveyard at S. Martino and a few tombs at Simbirizzi. In the 11th centuryAD Sardinia was divided into four Giudicati: Quartu, which included fourteen villas, belonged to the Giudicato of Cagliari. In 1066 Quartu was given to Cagliari's archbishop and then went back to Judge Torchitorio II of Cagliari. During the Aragonese rule, Quartu suffered from famines, plague, malaria and continuous raids from Saracen pirates, following the general path of decay of the whole of Sardinia. In 1793 the soldiers of a French fleet landed on the coast of Quartu, with the intention of conquering the whole island; the people of the city, led by Antonio Pisanu, assailed the French and repelled them after a bloody battle. Feudalism ended in 1836 under the baron Pes di Villamarina. In 1956 Quartu Sant’Elena was upgraded to the status of “city” by the President of ItalyGiovanni Gronchi.
