The Ottoman Empire at least nominally ruled Lebanon from its conquest in 1516 until the end of World War I in 1918.
The Ottoman sultan, Salim I (1516–20), invaded Syria and Lebanon in 1516. Salim I, moved by the eloquence of the Lebanese ruler Amir Fakhr ad Din I (1516–44), decided to grant the Lebanese amirs a semiautonomous status. The Ottomans, through the Maans, a great Druze feudal family, and the Shihabs, a Sunni Muslim family that had converted to Christianity, ruled Lebanon until the middle of the nineteenth century. It was during Ottoman rule that the term Greater Syria was coined to designate the approximate area included in present-day Lebanon, Syria, Jordan, and Israel.
Ottoman administration, however, was only effective in urban areas, while most of the country was ruled by tribal chieftains, based largely on their ability to collect taxes for the sultan. The system of administration in Lebanon during this period is best described by the Arabic word iqta', which refers to a political system, similar to other feudal societies, composed of autonomous feudal families that were subservient to the emir, who himself was nominally loyal to the sultan; therefore, allegiance depended heavily upon personal loyalty.
It was precisely this power structure, made up of fiefdoms, that allowed Bashir II, an emir from the Shihab dynasty in the Druze and Maronite districts of Mount Lebanon, to become the most powerful figure in Greater Syria during the first part of the 19th century. It was during this period that Lebanon saw increasing class and religious antagonisms that would define Lebanese social and political life for decades to come.
