BFC Germania 1888
BFC Germania 1888 was founded by 17-year-old Paul Jestram, his three brothers, and a number of their schoolmates from Askanischen Gymnasium at a time when football was not yet common in Germany, the first football games having been played in Berlin and Hamburg in the winter of 1881–82 by expatriate Englishmen. No football pitches had yet been built so "BFC" played on the Tempelhofer field where an airport would later be constructed.
TSC Eintracht Dortmund
Predecessor side "Dortmunder SC 1895" was established on 10 May 1895 as "Dortmunder Fussball Club 1895" and is recognized as the city's oldest football club. The team folded in 1897, but was re-formed on 27 October 1899. It was joined by "Fussball Club Union Dortmund" in 1910 and on 13 July 1913 merged with "Ballspielverein 1904 Dortmund" to become "Sportvereinigung Dortmund 1895" before first adopting the name "Dortmunder Sport Club 1895" in 1919. This combined side made an appearance in the top flight regional playoff round in 1920–21.
