The ethnographic composition of the town's population underwent radical change during the period of autonomy. In the 1881 census Heraklion had 6 025 Christians and 13 286 Muslims, but by 1900 the picture had altered, and the Muslim majority was overturned for the first time in centuries - there were 9 744 Christians and 9 565 Muslims. Over the ensuing years the increase in the Christian component assumed ever greater proportions, with 11 837 Christians to 8 195 Muslims in 1907 and 15 887 Christians to 9 248 Muslims in 1911. In that year the change found further expression in politics, as Heraklion acquired its first Christian mayor, Stylianos Georgiou, who succeeded Mustafa Deliachmetaki.
