The Lebanese Civil War (1975–1990) was a complex conflict in the form of various factions and shifting alliances between and among Lebanese Maronite Catholics, Lebanese Muslims, Palestinian Muslims, Lebanese Druze, and other non-sectarian groups. Governmental power had been allotted among the different religious groups by the National Pact based partially on the results of the 1932 census. Changes in demographics and increased feelings of deprivation by certain ethnic groups, as well as Israeli–Palestinian clashes in the south of the county all contributed to the outbreak of the Lebanese Civil War.
