The Mount Lebanon Mutasarrifate was one of the Ottoman Empire's subdivisions following the 19th-century Tanzimat reform. After 1861, there existed an autonomous Mount Lebanon with a Christian Mutasarrif (governor), which had been created as a homeland for the Maronites under European diplomatic pressure following the 1860 Druze–Maronite conflict. The Maronite Catholics and the Druze founded modern Lebanon in the early eighteenth century, through the ruling and social system known as the "Maronite-Druze dualism" in Mount Lebanon.
