What was the cause of black September?

Answer 1

The Black September Organization (BSO) was a Palestinian terrorist group most active in the early 1970s. The BSO named itself after the particularly bloody month in 1970 when King Hussein of Jordan declared military rule, expelling and killing thousands of Palestinian fedayeen (self-sacrificers). These fedayeen threatened to undermine Hussein's power in working with a "state within a state," the Palestine Liberation Organization (PLO), established to mobilize the Palestinian population against Israel. Black September most likely began as the Revenging Palestinians, a group dedicated to avenging the death of Abu Ali Iyad, the last charismatic leader of the fedayeen, whose torture and murder was intended as a symbol of defeat for the Palestinian guerrillas. After regrouping in Lebanon, where they were given control of fifteen refugee camps by the government, the Revolutionary Council of al-Fatah (the PLO's military force) met in Damascus, Syria, and debated whether it should continue using the tactics of Iyad's followers. The council, it is suspected, agreed to remain affiliated with the group, which later renamed itself Black September, and agreed to operate as a clandestine arm of al-Fatah.
