Break dancing emerged in the 1970s from the Bronx as a street dance that corresponded to the breaks in hip hop music. The moves were inspired by dances like the lindy hop and Charleston as well as martial arts. It became associated with competition and violence between dance crews. Films in the 1980s popularized break dancing worldwide, though it remains a dangerous dance due to moves performed on hard surfaces without protection. Elements of break dancing can still be seen in modern dances and music videos.
