The Black Liberation Army (BLA) was an underground, black nationalist-Marxist militant organization that operated in the United States from 1970 to 1981. Composed largely of former Black Panthers (BPP), the organization's program was one of "armed struggle" and its stated goal was to "take up arms for the liberation and self-determination of black people in the United States."[1] The BLA carried out a series of bombings, robberies (what participants termed "expropriations"), and prison breaks.
