The cakewalk or cake walk was a dance developed from the "prize walks" (dance contests with a cake awarded as the prize) held in the mid-19th century, generally at get-togethers on black slave plantations before and after emancipation in the Southern United States. Alternative names for the original form of the dance were "chalkline-walk", and the "walk-around". At the conclusion of a performance of the original form of the dance in an exhibit at the 1876 Centennial Exposition in Philadelphia, an enormous cake was awarded to the winning couple. Thereafter it was performed in minstrel shows, exclusively by men until the 1890s. The inclusion of women in the cast "made possible all sorts of improvisations in the Walk, and the original was soon changed into a grotesque dance" which became very popular across the country.
