Passage: Bayern is one of three professional football clubs in Munich. Bayern's main local rival is 1860 Munich, who was the more successful club in the 1960s, winning a cup and a championship. In the 1970s and 1980s, 1860 Munich moved between the first and the third division. The Munich derby is still a much-anticipated event, getting a lot of extra attention from supporters of both clubs. 1860 Munich is considered more working-class, and therefore suffers from a diminishing fan base in a city where the manufacturing sector is declining. Bayern is considered the establishment club, which is reflected by many board members being business leaders and including the former Bavarian minister president, Edmund Stoiber. Despite the rivalry, Bayern has repeatedly supported 1860 in times of financial disarray.Since the 1920s, 1. FC Nürnberg has been Bayern's main and traditional rival in Bavaria. Philipp Lahm said that playing Nürnberg is "always special" and is a "heated atmosphere". Both clubs played in the same league in the mid-1920s, but in the 1920s and 1930s, Nürnberg was far more successful, winning five championships in the 1920s, making the club Germany's record champion. Bayern took over the title more than sixty years later, when they won their tenth championship in 1987, thereby surpassing the number of championships won by Nürnberg. The duel between Bayern and Nürnberg is often referred to as the Bavarian Derby.
