National Socialist Party of America

The party's headquarters was in Chicago's Marquette Park, and its main activity in the early 1970s was organizing loud demonstrations against black people moving into previously all-white neighborhoods.

The marches and community reaction led the city of Chicago in 1977 to ban all demonstrations in Marquette Park unless they paid an insurance fee of $250,000 (equivalent to $1.26 million in 2023).

[1][2] While challenging the city's actions in the courts, the party decided to redirect its attention to Chicago's suburbs, which had no such restrictions.

[4] In 1977 Collin announced the party's intention to march through the largely Jewish community of Skokie, Illinois, where one in six residents was a Holocaust survivor.

Represented by a Jewish ACLU lawyer in court, they won the right to march on First Amendment grounds in National Socialist Party v. Village of Skokie, a lawsuit carried all the way to the U.S. Supreme Court, though it failed to carry through its intention (at the last minute, Chicago relented and they marched there instead).
