The ratio of Muslims to Christians fluctuated throughout the period of Ottoman domination. In 1777–78, 47,000 Muslims constituted a majority over the island's 37,000 Christians. By 1872, the population of the island had risen to 144,000, comprising 44,000 Muslims and 100,000 Christians. The Muslim population included numerous crypto-Christians, including the Linobambaki, a crypto-Catholic community that arose due to religious persecution of the Catholic community by the Ottoman authorities; this community would assimilate into the Turkish Cypriot community during British rule.
