In 1974, the PLO was named the sole legitimate representative of the Palestinian people and Yasser Arafat received a standing ovation at the General Assembly of the UN. But another Arab country was to be the stage for the next chapter of the Palestinian tragedy. After its expulsion from Jordan, the PLO had moved its headquarters to the Lebanese capital, Beirut. In April 1975, civil war broke out in Lebanon. In 1982, Israel launched an invasion of Lebanon and Palestinian forces quickly collapsed and the PLO was driven out of Beirut. After more than 10 years in Lebanon, it was the end of an era.
