Lebanese Civil War
By 1975, demographic trends and a large influx of Palestinian refugees led Muslims to become the majority population in Lebanon, undermining the authority of the mandatorily majority-Christian government. On April 13 of that year, fighting broke out between government-aligned Phalangists and the leftist-aligned Palestinian Liberation Organization, triggering civil war. The following year, Syria invaded Lebanon in support of the government, and though unable to effect any major advantage, continued occupying much of the country.
