A Race riot was a riot caused by ethnic tensions.
During the 31st century, Vaskans engaged in a race riot on the Kyrian and Vaskan homeworld. Although tensions had been building for some time, the catalyst were accusations of Revisionist history at the Museum of Kyrian Heritage, and at one point rioters entered the museum and smashed exhibits. The unrest, which also included protests and vandalism, continued even after the museum was cordoned off. At least two people were killed. (VOY: "Living Witness")
