The story
Badminton Denmark was established on 15 January 1930 as Denmark's Badminton Union (Danish: Dansk Badminton Union) by representatives from Skovshoved, Copenhagen BK, Neyes BK, Helsingør BK, Stubbekøbing IF and Roskilde BK. In order to avoid confusion with Danish Football Association (Danish: Dansk Boldspil Union) which also uses the initial DBU, the name was later changed to Danish Badminton Federation (Danish: Dansk Badminton Forbund).
