Tripoli was probably founded after 700 BC, as there is no mention of it until Persian times when it was the capital of the Phoenician federation of Tyre, Sidon, and Aradus and was divided into three sections. The city flourished under the Seleucid and Roman empires. In AD 638 it was captured by the Arabs. After a long siege it was taken (1109) by the Crusaders; during the siege its great library was destroyed. Tripoli was sacked by the sultan of Egypt in 1289 and was later rebuilt. The British conquered it from the Turks in 1918, and it became part of Lebanon in 1920.
Tripoli was the scene of heavy fighting during the 1975?76 civil war. It became the headquarters for the Palestine Liberation Organization (PLO) after the Israeli invasion of Lebanon in 1982. In the wake of rebellion against the PLO in 1983, large numbers of Palestinian rebels fled the city. Syrian military forces began to move into the city in the mid-1980s; like Beirut, it became a Lebanese city marked by battles for hegemony. After Syria's withdrawal from Lebanon in 2005, the city became the scene of clashes between Sunnis and Alawites, a situation that was aggravated beginning in 2011 by the Syrian civil war.
