The full name of the club is 1. Fußball- und Sportverein Mainz 05. The nicknames are Die Nullfünfer or Karnevalsverein, because the city of Mainz, where the club is based, is known as one of Germany's carnival cities. During home matches, the "Narrhallamarsch", a well-known German carnival tune, is also played after every goal scored.
The club colours are red and white. As for the home stadium, the team plays in the Opel Arena with a capacity of 34,000 spectators for league matches. The club's rivals are Eintracht Frankfurt and 1. FC Kaiserslautern. Both are local clubs, so it is a local rivalry.
The club, based in the city of Mainz in the state of Rhineland-Palatinate, was founded in 1905 under the former name of 1. Mainzer Fußballclub Hassia 05. The club has merged with several other clubs over the years, three times. For this reason, its name has also changed many times. It has had its current name since 1945.
It played in the Bundesliga for the first time in the 2004/05 season, but did not stay there for long. Success in the second highest competition came in the 2008/09 season, when they won promotion back to the Bundesliga under new Norwegian coach Jørn Andersen. He has been playing in the Bundesliga ever since the upcoming season. In 2009, they reached the semi-finals of the DFB-Pokal League Cup for the first time, knocking out clubs like SV Babelsberg 03, 1. FC Köln, SC Freiburg and Schalke 04 along the way.
Although he had success, Andersen didn't stick with the team too long as the team fell to VfB Lübeck in the opening round of the domestic cup. This had an impact on the coach's tenure, who subsequently left the team. The club has yet to achieve further success or reach the top of the top flight. After Andersen's departure, the Bundesliga is more in the second half of the table.
