Glen Echo Park used to be an amusement park up until the 1960s. For a large part of its time as an amusement park, it was racially discriminatory and only allowed whites to enter. Even so, on June 30th of 1960 a group of college students protested this racially seclusive park by staging a sit in at the carousel. Five African American students were arrested and the case was ultimately appealed to the supreme court where the convictions were reversed on the grounds that the state had used its police to aid a private business in racial segregation. In the 1961 season the park was open to people of all races.
