The more-or-less forced benevolence of the ship-owners made up for the deficiencies of the state, which was then obliged to hand over public revenues to them to meet its obligations. The Genoan family of Giustiniani, with their Maona, governed Chios, appointing a commissioner and commanding 52 military Genuates (tribes from around Genoa) in the island: during these years (1346-1566), the trade revived and the island enjoyed huge prosperity. The Mahona of Chios ended its activities in 1566 when the Turks invaded and occupied the island. Admiral Piyale Pasha annexed it to the Ottoman Empire. His sultan had a good pretext for putting an end to the government of the Giustiniani, for the island served as a place of refuge for fugitive slaves and the refreshment of Christian corsairs.
