AIK

[2] The club's achievements include Swedish championship titles in a slew of sports: football, ice hockey, floorball, bandy, handball, bowling, badminton, athletics, and many other sports, as well as the Wimbledon Championships and French Open in tennis (through Sven Davidson, Lennart Bergelin, and Ulf Schmidt).

The idea to start an athletic association began when the brothers Isidor and Paul Behrens were taking a walk through Hantverkargatan, in central Stockholm.

[citation needed] So the brothers gathered their friends, who had strong athletic interest, and held a meeting at Behrens' on 15 February 1891, on Biblioteksgatan 8, in central Stockholm.

[3] Fans of the club are referred to as AIK:are or gnagare (meaning rodent); both words are the same in singular and plural.

Black Army, Smokinglirarna, Ultras Nord, and Sol Invictus together with AIK-Tifo form the so-called AIK-Alliansen (the AIK Alliance).

[citation needed] In 1907, the Crown Prince of Sweden Gustaf Adolf became patron and first honorary member of the club.

This has since been in line with family tradition, and today the King of Sweden Carl XVI Gustaf is patron of the club.

[5] Notable fans of AIK include songwriter and producer Max Martin; DJ Sebastian Ingrosso; swimmer Sarah Sjöström; former leader of the Swedish Social Democratic Party Mona Sahlin; and Spotify founder Daniel Ek.

The club's biggest rival outside the Stockholm urban area is IFK Göteborg, Leksands IF, and Malmö FF.
