The group's name is derived from the Black September conflict begun on 16 September 1970, when King Hussein of Jordan declared military rule in response to a fedayeen coup d’état to seize his kingdom  — resulting in the deaths or expulsion of thousands of Palestinians from Jordan. The BSO began as a small cell of Fatah men determined to take revenge upon King Hussein and the Jordanian army. Recruits from the PFLP, as-Sa'iqa, and other groups also joined.
