Rhumba came to the United States from Cuba in the 1920s and became a popular cabaret dance during prohibition. Rhumba is a ballroom adaptation of son cubano and bolero (the Cuban genre) and, despite its name, it rarely included elements of Cuban rumba. It includes Cuban motions through knee-strengthening, figure-eight hip rotation, and swiveling foot action. An important characteristic of rhumba is the powerful and direct lead achieved through the ball of the foot. Rhumba is performed for both International Latin and American Rhythm.
