defeat, Candia (modern Iraklion) fell to the Ottomans in 1669 (though some offshore islands remained Venetian until 1715). Crete remained part of the Ottoman Empire until 1897. The fall of Crete was not accompanied by an influx of Muslims. At the same time, many Cretans converted to Islam – more than in any other part of the Greek world. Various explanations have been given for this, including the disruption of war, the possibility of receiving a timar (for those who went over to the Ottomans during the war), Latin-Orthodox dissension, avoidance of the head-tax (cizye) on non-Muslims, the increased social mobility of Muslims, and the opportunity that Muslims had of joining the paid militia (which the Cretans also aspired to under Venetian rule). It is difficult to estimate the proportion which became Muslim, as Ottoman cizye tax records count only Christians: estimates range from 30–40% By the late 18th century, as many as 30% of the islanders may have been Muslim. The Muslim population declined through the 19th century, and by the last Ottoman census, in 1881, Muslims were only 26% of the population, concentrated in the three large towns on the north coast, and in Monofatsi. People who claim descent from Cretan Muslims are still found in several Muslim countries today, and principally in Turkey. Between 1821 and 1828, during the Greek War of Independence, the island was the scene of repeated hostilities. Most Muslims were driven into the large fortified towns on the north coast and both the Muslim and Christian populations of the island suffered severe losses, due to conflicts, plague or famine. In the 1830s, Crete was an impoverished and backward island. Since the Ottoman sultan, Mahmud II, had no army of his own available, he was forced to seek the aid of his rebellious vassal and rival, Kavalalı Mehmed Ali Pasha of Egypt, who sent troops to the island. Starting in 1832, the island was administered for two decades by Mustafa Naili Pasha, whose rule attempted to create a synthesis between the Muslim landowners and the emergent Christian commercial classes. His rule was generally cautious, pro-British, and he tried harder to win the support of the Christians (having married the daughter of a priest and allowed her to remain Christian) than the Muslims. In 1834, however, a Cretan committee had already been founded in Athens to work for the union of the island with Greece.
