After the end of the second World War, football quickly became popular again in the population. Already in 1945, the American allied administration allowed the foundation of the Oberliga Süd. As this league, in contrast to the previous Gauliga Bayern, also included teams from Hesse and Baden-Württemberg, Bayern and 1860 became the only two clubs from Munich which resulted in an increased rivalry. Other Munich-based teams declined in importance. In this period, both teams could hardly point to successes with the exception of Bayern's victory in the 1957 German Cup.
