The term “swing dancing” is often extended to include other dances that do not have certain characteristics of traditional swing dances: West Coast Swing, Carolina Shag, East Coast Swing, Hand Dancing, Jive, Rock and Roll, Modern Jive, and other dances developed during the 1940s and later. A strong tradition of social and competitive boogie woogie and Rock ‘n’ Roll in Europe add these dances to their local swing dance cultures.
