Konfrontacja Sztuk Walki (KSW) Konfrontacja Sztuk Walki (KSW) is a Polish mixed martial arts (MMA) promotion founded in 2004 by Martin Lewandowski and Maciej Kawulski, based in Warsaw. It’s widely regarded as Poland’s premier MMA organization and one of the leading promotions in Europe, known for high-production events, a strong European roster, and large live audiences — including a record-setting show with over 57,000 spectators at Warsaw’s National Stadium. KSW events are broadcast domestically and internationally through TV and streaming partners, helping grow its fanbase outside Poland.
Distinct from some other global promotions, KSW built its reputation on spectacle-style fight cards and has steadily expanded its international presence with events in countries like France, the UK, and Ireland. With multiple weight-class titles and a mix of European and international fighters, KSW remains a key player on the European MMA scene and a major showcase for rising talent.
