BFC Germania 1888
BFC Germania 1888 was part of the country's first football league, the BDF (Bund Deutscher Fußballspieler or Federation of German Football Players) which was formed in November 1890 and was active until February 1892. The league was made up of the Berlin-based clubs BFC Vorwärts 1890, BFC Askania 1890, BFC Borussia 1890, BFC Concordia 1890, BFC Hellas 1890, BFC Tasmania 1890 and BFC Teutonia 1891. Germania emerged the winner in a tournament staged by the league, and as the DBF was the only football league in the country at the time, can lay claim to being Germany's first champion. Club records indicate that "BFC" then defended their title, but no supporting evidence has been found.
