Lebanon

One of the most war-torn nations of a war-torn region, the Lebanese Republic is situated on the eastern shores of the Mediterranean Sea north of Israel, bordered by Syria to the east and north. Much of Lebanon’s violent conflict is internal, the result of a long and terrible civil war. Prior to 1975, it was a prosperous and fairly neutral nation, known for agriculture, commerce, and finance.
A large population of Palestinian refugees fled to Lebanon after being displaced from Israel. The Palestine Liberation Organization, after being ousted from Jordan, likewise relocated to Lebanon. By 1975, violent conflict broke out between sectarian factions, including the PLO and Christian and Muslim militias. Syrian forces were called upon by the Lebanese government to aid in peace-keeping, drawing the military of the Arab League into the conflict.
PLO attacks on Israel from Lebanon led to an Israeli invasion, and a siege of the capitol city of Beruit. International forces attempted to supervise a withdrawal of PLO forces, but were hampered by ongoing conflicts and a series of devastating bombings.
