Camille Chamoun (kämē´yə shämōn´), 1900–1987, Lebanese political leader. Chamoun held a variety of governmental posts before serving as president of Lebanon (1952–58). A Maronite Christian, Chamoun was opposed by Muslim leaders who disliked his pro-Western policies. The Muslim groups openly rebelled against Chamoun's government in 1958, and, in response to Chamoun's request for help, U.S. marines were sent to support the government. After defending the Lebanese against Syria in the 1975 civil war, he held a succession of ministerial appointments.
