Lebanese diaspora refers to Lebanese migrants and their descendants who emigrated from Lebanon and now reside in other countries. There are more people of Lebanese origin (15,4 million) living outside Lebanon than within the country (6 million citizens). The Lebanese diaspora consists of Christians, Muslims, Druze, and Jews. The Christians trace their origin to several waves of emigration, starting with the exodus that followed the 1860 Lebanon conflict during the Ottoman Empire.
Under the current Lebanese nationality law, the Lebanese diaspora do not have an automatic right to return to Lebanon. Varying degrees of assimilation and a high degree of inter-ethnic marriages in the Lebanese diaspora communities, regardless of religious affiliation, have caused many of the Lebanese diaspora not to have passed fluency in Arabic to their children, although most still maintain a Lebanese national identity. Several factors have caused Lebanese emigration, including civil wars, attacks on Lebanese sovereignty and land by Israel and Syria, and political and economic crises.
