The popular burlesque show of the 1870s through the 1920s referred to a raucous, somewhat bawdy style of variety theater. It was inspired by Lydia Thompson and her troupe, the British Blondes, who first appeared in the United States in the 1860s, and ... by early "leg" shows such as The Black Crook (1866). Its form, humor, and aesthetic traditions were largely derived from the minstrel show. One of the first burlesque troupes was the Rentz-Santley Novelty and Burlesque Company, created in 1870 by M.B. Leavitt, who had earlier feminized the minstrel show with her group Madame Rentz's Female Minstrels.
