On 12 July 1470, during the Ottoman–Venetian War of 1463–1479 and after a protracted and bloody siege, the well-fortified city of Negroponte (Chalcis) was wrested from Venice by Mehmed II and the whole island fell into the hands of the Ottoman Empire. The Doge Francesco Morosini besieged the city in 1688, but was forced to withdraw after three months.
