The Byzantine rulers had little influence and through the Treaty of Nymphaeum, authority was ceded to the Republic of Genoa (1261). At this time the island was frequently attacked by pirates, and by 1302–1303 was a target for the renewed Turkish fleets. To prevent Turkish expansion, the island was reconquered and kept as a renewable concession, at the behest of the Byzantine emperor Andronicus II Palaeologus, by the Genovese Benedetto I Zaccaria (1304), then admiral to Philip of France. Zaccaria installed himself as ruler of the island, founding the short-lived Lordship of Chios. His rule was benign and effective control remained in the hands of the local Greek landowners. Benedetto Zacharia was followed by his son Paleologo and then his grandsons or nephews Benedetto II and Martino. They attempted to turn the island towards the Latin and Papal powers, and away from the predominant Byzantine influence. The locals, still loyal to the Byzantine Empire, responded to a letter from the emperor and, despite a standing army of a thousand infantrymen, a hundred cavalrymen and two galleys, expelled the Zacharia family from the island (1329) and dissolved the fiefdom.
