The Balboa, also known as "Bal", is a swing dance that emerged in Southern California during the early 1930s as a response to swing music. The earliest recorded reference to Balboa is 1932. This date coincides with what is generally accepted to be the beginning of swing. The dance enjoyed huge popularity in California during the 1930s and 1940s, and was still being danced by original dancers into the 21st century.
Balboa is a dance that distinctively relies on closed position. The earliest form of the dance emerged in the high schools and dance venues of southern California. Spaces were often limited, the floor was waxed and there was traditionally a line of dance around the room. Balboa is danced into the floor and drifts without a prescribed line of dance. Although it is not clear when, strict codes of conduct could be enforced in some venues with signs stating 'no breaks'. These dance halls were usually addressing wild kicks of other dances, specifically So Cal Swing, or simply unruly dancers. Ballrooms famous as Balboa venues displayed 'no-break' signs, with bouncers monitoring the dancers.
