As in most other parts of the world, the decades following the World War II were relatively free from football violence and the supporter culture did not change much. Swedish football culture started to change in the late 1960s, becoming heavily inspired and influenced by the English supporter culture. This flourished in the 1970s and 1980s, giving birth to some of the most well-known Swedish supporters clubs, AIK's Black Army, Djurgårdens IF's Blue Saints (later Järnkaminerna), and IFK Göteborg's supporters club, Änglarna (the Angels). The first attempt to found an IFK supporters club was made in 1969, but interest diminished when IFK Göteborg were relegated from the highest league the following year. The supporters club was not re-founded until 1973, which is considered the year of foundation of Änglarna.
