Abbot Howard "Abbie" Hoffman (1936-1989) was a political and social activist, especially in the 1960s. The FBI investigated Hoffman under anti-riot laws and as a domestic security threat. The files in this release range from 1968 to 1973 and cover Hoffman’s role as a leader in the Yippie Party (Youth International Party), his role in anti-war protests at the 1968 Democrat National Convention in Chicago, and his subsequent trials as one of the “Chicago Eight” conspiracists.
