Mambo is a Latin dance of Cuba which was developed in the 1940s when the music genre of the same name became popular throughout Latin America. The original ballroom dance which emerged in Cuba and Mexico was related to the danzón, albeit faster and less rigid. In the United States, it replaced rhumba as the most fashionable Latin dance. Later on, with the advent of salsa and its more sophisticated dance, a new type of mambo dance including breaking steps was popularized in New York. This form received the name of "salsa on 2", "mambo on 2" or "modern mambo".
