History of roller derby The term derby, meaning a race or multi-race event, appeared in the press as early as 1922, when the Chicago Tribune announced and reported on the results of two "roller derby" events held that year. These were multi-day events during which various roller skating races were held on a flat track at Chicago's Broadway Armory.[17][18][19]
