Idrottsföreningen Kamraterna Göteborg, commonly known as IFK Göteborg or simply Göteborg, is a Swedish professional football club based in Gothenburg. Founded on 4 October 1904, it is the only club in the Nordic countries that has won a pan-European competition, as the club won the UEFA Cup in 1982 and 1987. IFK is affiliated with Göteborgs Fotbollförbund and play all their home games at Gamla Ullevi since the start of the 2009 season. The club colours are blue and white, colours shared both with the sports society — Idrottsföreningen Kamraterna — which the club originated from, and with the home town of Gothenburg.
Besides the two UEFA Cup titles, they have won 18 Swedish championship titles, second most in Swedish football after Malmö FF, and have the third most national cup titles with seven. The team has qualified for four group stages of the UEFA Champions League, and reached the semi-finals of the 1985–86 European Cup. IFK Göteborg is the only Swedish club team in any sport to have won the Radiosportens Jerringpris — an award for best sports performance of the year voted by the Swedish people — for the 1982 UEFA Cup victory. IFK is the most popular football club in Sweden, with diverse country-wide support.
They currently play in the highest Swedish league, Allsvenskan, where they have played for the majority of their history. They have played top-flight football in Sweden continuously since 1977, which currently is the longest top-flight tenure of any club in Sweden. The club won it's first Swedish championship in 1908, four years after the founding, and has won at least one championship title in all decades since, except the 1920s, 1970s and 2010s. IFK Göteborg's most successful period was from 1982 to 1996, when the team prospered in European football and won 10 out of 15 Swedish championships.
