Why did the Palestine Liberation Organization establish its headquarters in Beirut?

The Palestine Liberation Organization (PLO) established its headquarters in Beirut primarily as a result of its forced expulsion from Jordan in 1971. Following the 1967 Six-Day War, the PLO had utilized bases in Jordan to launch guerrilla attacks against Israel, which led to significant instability and eventual conflict with the Jordanian government.12

After being expelled by the Jordanian army, the organization shifted its operations to Lebanon. Beirut subsequently became the movement's headquarters, serving as a prominent center for Palestinian resistance organizations. This relocation placed the PLO at the heart of Lebanon's political landscape, where it became deeply embroiled in the country's sectarian disputes and contributed to the onset of the Lebanese Civil War. The PLO remained based in the capital until it was forced to evacuate following the Israeli invasion of Lebanon and the subsequent siege of Beirut in 1982.13245
