In 1516, the Ottoman Empire conquered Western Asia. The Ottomans reorganized Syria into one large province or eyalet. The eyalet was subdivided into several districts or sanjaks. In 1549, Syria was reorganized into two eyalets; the Eyalet of Damascus and the new Eyalet of Aleppo. The majority of historical Palestine became part of the Eyalet of Damascus until 1660, and later became part of the Eyalet of Sidon.
