In 1516, the Ottoman Empire invaded the Mamluk Sultanate of Egypt, conquering Syria, and incorporating it into its empire. The Ottoman system was not burdensome to Syrians because the Turks respected Arabic as the language of the Quran, and accepted the mantle of defenders of the faith. Damascus was made the major entrepot for Mecca, and as such it acquired a holy character to Muslims, because of the beneficial results of the countless pilgrims who passed through on the hajj, the pilgrimage to Mecca.
