BFC Dynamo played only a minor role in football in Berlin until the relocation of FC Vorwärts Berlin to Frankfurt an der Oder in 1971. The club initially had modest support. But with its growing successes in the 1970s, the club began to attract young fans, primarily from the central areas around the Friedrich-Ludwig-Jahn-Sportpark, such as Prenzlauer Berg and Mitte. Many came from working class families in Prenzlauer Berg. One of the first big supporter groups of BFC Dynamo was Black Eagles. The fan club was founded in 1972 and was one of the earliest fan clubs in East German football. Fans of BFC Dynamo were the first to sew their embroidered fan club badges on their jackets. This was a novelty among football supporters in East Germany in the 1970s.
