The derby of the textile-workers city Lodz excites entire Poland since the beginning of the eighties. In short time it has become one of the greatest derbies in the country (fans of both sides claim the greatest). LKS is the oldest club of Lodz and before second World War it was much more popular than Widzew, which was only a small club of workers from one of city districts. In the eighties and nineties Widzew became one of the best teams in Poland and it gained popularity not only in Lodz but also in other parts of the country. Because of that LKS fans calls their rivals "peasants". However, nowadays both clubs have comparable amount of support in all social classes in Lodz.
