In 1977 and 1978, Illinois neo-Nazis of the National Socialist Party of America (NSPA) attempted to hold a march in Skokie, far from their headquarters on Chicago's south side. Originally, the neo-Nazis had planned a political rally in Marquette Park in Chicago. The park is located in what was then a predominantly all-white neighborhood, similar to the situation in 1966, when a crowd of 4,000 Marquette Park residents gathered to watch Martin Luther King Jr. lead a march, some waving Confederate flags or throwing bottles, bricks and rocks at the protesters; King was knocked to his knees when struck by a rock. However, the Chicago authorities thwarted the NSPA's plans.
