The Chicago Seven (originally Chicago Eight, also Conspiracy Eight/Conspiracy Seven) were seven defendants—Abbie Hoffman, Jerry Rubin, David Dellinger, Tom Hayden, Rennie Davis, John Froines, and Lee Weiner—charged by the federal government with conspiracy, inciting to riot, and other charges related to anti-Vietnam War and countercultural protests that took place in Chicago, Illinois, on the occasion of the 1968 Democratic National Convention. Bobby Seale, the eighth man charged, had his trial severed during the proceedings, lowering the number of defendants from eight to seven.
Seale was eventually sentenced to four years in prison for contempt of court, although this ruling was later reversed.
After a federal trial resulting in both acquittals and convictions, followed by appeals, and reversals, some of the seven defendants were finally convicted, although all of the convictions were reversed.
The 1968 Democratic National Convention was held in Chicago in late August to select the party's candidates for the November 1968 presidential election. Prior to and during the convention—which took place at the International Amphitheatre—rallies, demonstrations, marches, and attempted marches took place on the streets and in the lakefront parks, about five miles away from the convention site. These activities were primarily in protest of President Lyndon B. Johnson's policies for the Vietnam War, policies which were vigorously contested during the presidential primary campaign and inside the convention.
