Chemnitzer

The club was initially formed by students from Mittweida as Chemnitzer SC Britannia on 2 December 1899.

On 28 January 1900, Chemnitzer SC Britannia was a founding member of the German Football Association (DFB) in Leipzig.^[] During April the same year, the club changed its name to Chemnitzer BC 1899.

On 8 August 1903, the club became a founding member of the Verband Chemnitzer Fußball-Vereine (VCFV).^[] This local federation was included into the Verband Mitteldeutscher Fußball-Vereine (VMBV), the great regional federation of Central Germany, two years later.

Until 1933, Chemnitzer BC were a strong side of the VMBV leagues.^[] They took part in the WMBV's final round fifteen times, reaching the final once in 1927.^[] Despite a 0–4 defeat against VfB Leipzig, Chemnitz qualified for the 1927 German football championship as vice-champions, where they lost in the first round against eventual champions 1. FC Nürnberg, 1–5.

In 1933, Chemnitzer BC 1899 came into financial difficulties.^[] Despite a merger with local rivals SC Sachsen 1909 Chemnitz, bankruptcy and liquidation could not be avoided.^[] The side was then immediately re-formed under the name Chemnitzer BC 1933, which assumed the history of the old club.^[] CBC 1933 were part of the Gauliga Saxony until the end of World War II.

FC Karl-Marx-Stadt

In the aftermath of the conflict, most organizations in Germany, including sports and football clubs, were dissolved by the Allied occupation authorities. The side was re-established in 1945 as SG Chemnitz Nord before, as it was common in East German football at the time, undergoing a number of name changes, from BSG Fewa Chemnitz in 1948 to BSG Chemie Chemnitz in 1951.^[] Upon the renaming of the city of Chemnitz to Karl-Marx-Stadt in 1953, the club followed suit and assumed the new city name as well. In 1956, the football club was attached to the larger centralized sports club SC Motor Karl-Marx-Stadt, which was in turn renamed SC Karl-Marx-Stadt in 1963.^[] The football department was then once again separated from the sports club as FC Karl-Marx-Stadt in 1966, under a government plan to establish a number of football clubs as centres throughout the country intended to identify and develop talent in support of a strong national side. When the city re-claimed its original name in 1991, the team followed suit to become Chemnitzer FC.

After joining the DDR-Oberliga for the 1962–63 season, the club generally^[] earned uninspiring^[] results, most often finishing in the lower half of the league table.^[] They managed a surprising^[] East German championship win at the end of the 1966–67 season, and were runners-up in the East German Cup (FDGB Cup) in 1969, 1983 and 1989.^[] The club enjoyed^[] its best international turn in 1989, advancing through two preliminary rounds to the Round of 16 of the 1989–90 UEFA Cup before being knocked out against Juventus.^[] In the same season the team finished as runners-up in the East German championship, second to Dynamo Dresden on goal differential.

After German reunification in 1990, Chemnitzer FC qualified for the 2. Bundesliga at the end of the 1990–91 NOFV-Oberliga. Beginning with the 1991–92 season, Chemnitz spent five years in the second tier of German football until being relegated to the then third-tier Regionalliga in 1996, and also advanced to the semi-final of the 1992–93 DFB-Pokal during this time. Since then, the importance of the club has faded.^[] The following four years were evenly split between the Regionalliga and the 2. Bundesliga, before eventually being relegated back to the Regionalliga (III) in 2001, and subsequently to the NOFV-Oberliga Süd (IV) in 2006. The last couple of years,^[][] however, saw the club slowly rising through the German league system once again with promotions to the now fourth-tier Regionalliga in 2008 and the 3. Liga in 2011. In 2018, the club was relegated to the fourth league.

The club was at the centre of a controversy after the club, some of its players and fans paid tribute to Thomas Haller, a prominent far-right activist before kick-off against VSG Altglienicke at home on 9 March 2019. Haller, who provided security for the club and co-founded HooNaRa (Hooligans-Nazis-Racists) in the 1990s received a minute's silence, while a picture of Haller was displayed on a large screen at the stadium. Chemnitzer FC forward Daniel Frahn held up a shirt honouring Haller and other "local hooligans". The club's chief executive Thomas Uhlig resigned as a result of the controversy, and Sparkasse Chemnitz said it would no longer sponsor the club after the end of that season.

In August 2019, the club sacked its captain, Daniel Frahn, after he was accused of "openly displaying" his sympathy for neo-Nazi groups among the club's supporters.^[]
