VfR Mannheim

After the 1933 re-organization of German football under the Third Reich into sixteen top flight regional leagues, Mannheim began play in the Gauliga Baden. The club performed well in the years leading up to World War II and the throughout the conflict, taking division titles in 1935, 1938, 1939, 1943 and 1944. However they could not translate this success in league play into success in the national playoffs with their best result being an advance to the 1943 quarterfinals where they were put out 2–3 by eventual vice-champions FV Saarbrücken.

Mannheim repeated as division champions in 1944. Wartime conditions made playing football increasingly difficult in the country, so much so that the national playoffs were initially abandoned and VfR declared champions by the sport's governing authority. However, this decision was revoked after protests from other clubs and the playoff competition reinstated. Mannheim advanced only as far as the eighth final before being eliminated by 1. FC Nürnberg.

Historical chart of VfR Mannheim league performance

After the war VfR Mannheim played in the first division Oberliga Süd where they earned unremarkable results until a surprising breakthrough in 1949 that saw the team transform a distant second-place finish in their division into a national championship. After thrashing Hamburger SV 5–0 in the opening round, they upset Kickers Offenbach, who had finished eleven points ahead of them in their Oberliga division that season, by a score of 2–1. VfR then earned a come from behind 3–2 overtime victory over Borussia Dortmund in front of 90,000 fans in the final. Between 1903 and 1944 German national champions were awarded the Viktoria trophy. The 1944 final between Dresdner SC and Luftwaffen-SV Hamburg was the last Viktoria match ever played as the trophy disappeared at war's end. The missing prize was replaced by the Meisterschale in 1949 and was first awarded to Mannheim despite 1. FC Nürnberg being Germany's first postwar champions in 1948. Today the Meisterschale recognizes the country's Bundesliga champions and is inscribed with the names of each national championship team since 1903. The Viktoria has since been recovered and is held by the German Football Association.

The next year they again met Dortmund in the playoffs, this time in the opening round, and once again eliminated them. However, they would themselves be put out in the next round by Preußen Dellbrück and begin a slide into anonymity.

Mannheim played in the second tier Regionalliga Süd formed in 1963 at the same time as Germany's new professional league, the Bundesliga. After ten years near or at the bottom of the league table they fell to tier III football, the Amateurliga Nordbaden. Despite ongoing financial problems they rebuffed offers of a merger from SV Waldhof Mannheim in 1998 and again in 2003. They were denied a license that year and driven to the Verbandsliga Nordbaden (V). However, the side performed well enough to win their division the next season and promotion to Oberliga Baden-Württemberg (IV), where they play today. With a sixteenth place in 2007–08, they narrowly avoided relegation, being on equal points with the seventeenth team.

After suffering relegation in 2009, the club took two seasons to recover before returning to the Oberliga in 2011. In its first season back the club finished second in the league behind SSV Ulm 1846. In the 2014–15 season the club came second-last in the league and was relegated to the Verbandsliga.
