On 21 November 1990, German football reunified when the former East German territories joined the DFB as a new regional association.
Founded in 1900, the Deutscher Fußball-Bund was disbanded after World War II, but reformed as Western Germany's governing body in 1950. Meanwhile, Eastern Germany formed their own association, the Deutscher Fußball-Verband der DDR (DFV). The two nations maintained two separate leagues and competed independently at the international level, with West Germany winning the 1954, 1974, and 1990 World Cups and East Germany taking the gold medal at the 1976 Summer Olympics.
The two German states reunited on 3 October 1990. On 20 November, the DFV formally disbanded, with the DFB assuming control of all German football. The DFB held a meeting the following day and agreed to accept the former DFV territories as a new regional association--the Northeast German Football Association. Clubs from the former East Germany joined the Bundesliga system, with two of them--Hansa Rostock and Dynamo Dresden--joining the top flight for the 1991-92 season.
Since the merger, however, only teams from the former West Germany have won the Bundesliga or the German Cup.
