Throughout the 18th century and into the 19th century more and more Maronites settled in the Druze regions of the Mount. The Druze viewed these Maronite settlements as a threat to their power in Mount Lebanon and in a series of clashes in the 1840s and 1860s, a miniature civil war erupted in the area resulting in the massacre of thousands of Christians. The Druze won militarily, but not politically, because European powers (mainly France and Britain) intervened on behalf of the Maronites and divided Mount Lebanon into two areas; Druze and Maronite. Seeing their authority decline in Mount Lebanon, a few Lebanese Druze began migrating to the new Jabal ad-Duruz in southern Syria. In 1861, the Mount Lebanon autonomous district was established within the Ottoman system, under an international guarantee.
