The Mount Lebanon Mutasarrifate was one of the Ottoman Empire's subdivisions following the 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.

The 1860 civil conflict in Mount Lebanon and Damascus was a civil conflict in Mount Lebanon during Ottoman rule in 1860–1861 fought mainly between the local Druze and Christians. Following decisive Druze victories and massacres against the Christians, the conflict spilled over into other parts of Ottoman Syria, particularly Damascus, where thousands of Christian residents were killed by Muslim and Druze militiamen. The fighting precipitated a French-led international military intervention.
