[1] The club dominated competition in the city in the period leading up to World War I. DSV joined the top-flight regional Südostdeutscher Fußballverband (SOFV) when the league grew to include Posen in 1909.

They were the dominant side in the city and advanced to the SOFV playoffs in four of five seasons prior to the outbreak of World War I in 1914.

Football competitions in many parts of Germany were disrupted between 1914 and 1918 by the war and the country was left in disorder following its defeat in the conflict.

An uprising succeeded in restoring an independent Republic of Poland, now called Second, built around Poznań, which was the historic center of the country.

DSV Posen was refounded in 1940 and was again part of German football competition, however the club did not make its way back to top level play and disappeared at the end of the World War II in 1945.
