Football hooliganism
Football hooliganism in Poland first developed as a recognised phenomenon in the 1970s, and has continued since then with numerous recognised hooligan firms and large-scale fights. Until 1997, the number of related incidents rose, according to Przemysław Piotrowski of Jagiellonian University. The problem of hooliganism related to football has been compared to what he described as the dark days of football hooliganism in Eastern Europe in the 1980s. Hooliganism in Poland is comparable in its scale to what notoriously used to happen in England, but no longer does. Many Polish football clubs have hooligan firms associated with them.
