On September 4, 1949, a concert by Paul Robeson in Peekskill, New York, was disrupted by a violent mob, preventing the performance from taking place. Robeson, a renowned African American singer, actor, and political activist, had been a prominent figure in advocating for civil rights and against racial injustice.

This particular concert was part of a series of events organized by those supporting his activism, but it became infamous when a crowd of protesters, including many from local right-wing groups, began throwing rocks and chanting insults as Robeson attempted to perform. The riot led to several people being injured, and the concert had to be canceled for safety reasons.

The incident is significant not only for the violence that occurred but also as an example of the growing political tensions in post-World War II America. Robeson, known for his strong left-wing views and support of the Soviet Union during the Cold War, had become a target for anti-communist groups, leading to a backlash against his performances and activism. This event was one of many that illustrated the divisiveness of the era and the personal and professional costs that Robeson faced because of his outspoken political beliefs.
