Communist Youth of Denmark
Danmarks Kommunistiske Ungdom, was the youth wing of Danmarks Kommunistiske Parti. DKU had its origins in Socialdemokratisk Ungdomsforbund founded in 1906. The organization took the name DKU in 1919.
DKU was dissolved in 1990, but in 2009, a spiritual successor was founded as an independent organization shared informally between the Communist Party of Denmark, the Communist Party in Denmark, and the Communist Party (Denmark), which still participates in the World Federation of Democratic Youth.
