The document discusses several popular dances that emerged and gained widespread popularity during the 1920s as a form of entertainment and self-expression following World War 1. Some of the most prominent dances included the Charleston, Lindy Hop, and Fox-Trot. The Charleston was an energetic dance originating from South Carolina that involved kicking legs outwards. The Lindy Hop combined acrobatic improvisation with swing music. The Fox-Trot started in 1914 and evolved into a smoother dance in the 1920s that was both popular and controversial.
