The fan movement at Zawisza started in the 1970s, one of the first clubs with organised support in the country. Since then club has always attracted a large support considering its relative lack of success. The club enjoys support from around
Cuiavia, with fan-clubs in several other major towns, most notably in
Inowrocław,
Janikowo,
Nakło and
Mogilno, among several others. The fans have good relations with fans of
ŁKS Łódź,
GKS Tychy,
Zagłębie Lubin and
Górnik Wałbrzych. Their arch-rivals are fellow locals
Polonia Bydgoszcz, with whom they contest the
Bydgoszcz Derby, and regional rivals
Elana Toruń, with whom they play the
Cuiavian Derby, with the
Toruń and
Bydgoszcz rivalry between the two cities one which goes even beyond sport.
Protests In the 21st century, the Zawisza fans have encountered numerous challenges from owners, city council, politicians and the media, frequently battling against them for public support. First they opposed the controversial merger with
Chemik Bydgoszcz in 2001, choosing to boycott the
new merged club (which turned out to be hugely unsuccessful) and support the reserve team which still played under the Zawisza name. Following the incident, the fans asked to see the security footage, however, the footage was claimed to be lost due to an alleged "technical fault". The club chairman, Radosław Osuch, and a large portion of the media and public opinion, attributed the incident to
football hooliganism. The players supported the chairman, sparking fury from the fans. Osuch threatened to relocate the club, and has openly declared war against the fans He changed the club crest to the similar crest used by the
relocated Zawisza in 2006, further angering the fans. Since 2014, the boycott has been upheld, meaning that there has been low attendances and support during matches, including the historic
Polish Cup win. In January 2015, a group of fans broke into the stadium and placed 15 coffins on the pitch, depicting 14 players and the chairman, and a banner with the words ''"Osuch's whore spares, you are morally dead"'', as a protest against the chairman and the players. The club issued a criminal investigation into the incident. In May 2015, after Górnik Łęczna keeper
Sergiusz Prusak displayed a T-shirt showing his support to the Zawisza fans, the Zawisza fans decided to break their boycott for one match only to come and thank him in a match against Górnik. In order to prevent the fans from coming to Zawisza, Osuch subsequently raised the match ticket price to a very high 200
zł in order to stop the fans attending. After 5 years, Osuch decided to leave the club, however upon this announcement the players and staff also all resigned. Without investment, the club was disbanded by Osuch as last act, stating that there is a poor atmosphere surrounding Polish football. The fans reformed the club and had to start the new season from the lowest level on the
football pyramid. ==Ground==
