Hammarby IF Fotbollförening, more commonly known as Hammarby Fotboll or Hammarby ( or, especially locally, ), is a Swedish football club from Stockholm founded in 1915. The club is based at Tele2 Arena in Johanneshov but founded in the neighbouring Södermalm district of Stockholm City Centre, an area the club considers its heartland. Competing in Sweden's first tier, Allsvenskan, Hammarby are placed tenth in the all-time Allsvenskan table, and has won the league once, in 2001. The club has competed in the Svenska Cupen final five times, winning their first title in 2021. The club's colours are green and white, which are reflected in its crest and kit. Between 1918 and 1978, however, the club played in black-and-yellow striped home shirts, which since often form the club's away colors. It is known for its vociferous fans and for having the highest average attendance in the Nordic countries. Drawing inspiration from England, Hammarby fans introduced football chants to the Swedish terraces in 1970. Hammarby is one of largest football clubs in Europe in terms of the number of active players of all ages – with some 3,500 players in its organisation. Hammarby is affiliated with the Stockholms Fotbollförbund (Stockholm Football Association). History In 1889, Hammarby Roddförening ("Hammarby Rowing Association") was established in Södermalm, with engineer Axel Robert Schönthal, the first chairman, being credited as the founder. By 1897, it had diversified into different sports, and was renamed Hammarby Idrottsförening ("Hammarby Sports Club"), or Hammarby IF for short. 1915–1940s: Establishment of football club In 1915, the sporting ground Hammarby IP was built in Södermalm. Due to a lack of football pitches in Stockholm, several other clubs proposed to merge with Hammarby IF to get access to the stadium. An offer from Klara SK was accepted and Hammarby officially established a football department on 13 August 1915. The club played its first competitive game two days later, and won 5–0 against Västerås SK in the "Östsvenska serien", a local league, with Ragnar Gunnarsson scoring the inaugural goal. In 1916, Hammarby competed in Svenska Mästerskapet, a cup by then held to decide the Swedish Champions, for the first time. In 1918, Hammarby also merged with Johanneshofs IF, a club from the neighbouring district Johanneshov. In 1920, Hammarby first competed in the Svenska Serien, by then the highest league in Swedish football, with key players like goalkeeper Victor Olsson, defender Gösta Wihlborg and forward Gustav
