Deutsche Jugendkraft Sportverband (DJK, English: German Youth Power Sports Association) is a Catholic-sponsored sports association in Germany. Founded as a faith-based organization, today it is open to anyone who supports its goals. The concept of Jugendkraft or "youth power" is common to many countries and cultures, as in the Italian Juventus, and conveys the positive aspects of youthful energy and creativity.
The DJK was established in Würzburg in 1920 under the leadership of Monsignor Carl Mostert and was active nationally until 1933 and the rise to power of the Nazis. Faith-based and worker's organizations were regarded as politically unpalatable by the regime and DFK-affiliated clubs were at that time dissolved or forced into mergers with mainstream clubs. On 1 July 1934, DJK head Adalbert Probst was arrested by the Gestapo before being shot the next day. By early 1935, the DJK and similar organizations were banned outright.
Following World War II, organizations of all types were banned across the country by occupying Allied authorities as part of the process of de-Nazification. New sporting organizations slowly emerged and the DJK was re-formed in 1947 as the "Verband für Sportpflege in katholischer Gemeinschaft" (Catholic Sports Association for Community Care). Former DJK head Prelate Ludwig Wolker played an important role in bringing together the myriad of feuding postwar sports bodies under the national umbrella organization Deutscher Sportbund (German Sports Federation) in 1950. Within the DJK, a fierce factional dispute arose over whether the organization should return to being a separate and purely Catholic organization as it had been before the war, or an ideologically neutral organization that would integrate itself with other national sporting groups. In 1961 the DJK joined the Deutscher Sportbund. The previously separate men's and women's DJK groups were merged in 1970.
Today the organization acts as mediator between the church and sports, and places an emphasis on the role of faith in a sporting context. Based in Düsseldorf, the DJK is a member of the German Olympic Sports Confederation (member with special responsibilities) and the Fédération internationale catholique d'éducation physique et sportive (International Organization of Catholic Sports Associations). The DJK-Sportjugend (DJK-Youth Sport) is an independent youth organization and a member of Deutschen Sport Jugend (German Youth Sport) and the Bund der Deutschen Katholischen Jugend (Federation of German Catholic Youth).
