Konfrontacja Sztuk Walki (English: Martial Arts Confrontation), better known by its initials KSW, is widely considered to be the premier mixed martial arts organization in Poland[1] and one of the leading in Europe.

Martin Lewandowski had been the manager of the Hotel Marriott in Warsaw when he met Maciej Kawulski in 2002.

Kawulski was organizing one of the biggest sports expos in Poland at that time, and as both businessmen come from martial arts backgrounds, they quickly found a common subject.

[5] In 2017, KSW 39: Colosseum beat the record for the largest live attendance to a MMA event in Europe, and second-largest in history with 57,776 fans, only after the Pride Shockwave in 2002 and ahead of UFC 193.

KSW has its own fight team, the KSW Team, which consists of some of the promotion's elite fighters, such as Mamed Khalidov, Jan Błachowicz, Krzysztof Kulak, Łukasz Jurkowski or Antoni Chmielewski.

KSW co-operates with many other promotions in Europe by exchanging fighters, for example WFC and The Cage.

Since KSW XI, the promotion runs its shows live on nationally available at private free-to-air television network Polsat.

On November 22, 2021, KSW announced a long-term partnership with streaming platform Viaplay.

Contract includes increasing number of KSW events to 12 per year and exclusive rights to Viaplay to broadcast KSW events on its platform for the Polish, Nordic, Scandinavian, Dutch and English markets.

The agreement is concluded for the entire year 2023 and will be valid for ten out of twelve planned galas, of which six of these events will be called XTB KSW.

In other cases, XTB will be a strategic sponsor, just like in 2022 - at galas in Łódź, Toruń, Radom and Warsaw.

[9] On May 10, 2023, the KSW federation announced the introduction of the Hall of Fame, intended to recognize players every year, as well as other people who have made a unique contribution to the history of the organization.

The official ceremony of Jurkowski's introduction to the Hall of Fame took place during the XTB KSW 83: Colosseum 2 gala.

[11] On February 24, 2024, a special XTB KSW Epic gala took place, focusing on organizing fights in formulas other than just MMA.

[12] During the fight of the evening of this event, Mamed Chalidow and Tomasz Adamek crossed gloves in the boxing formula.

[13] The KSW ring announcer is Waldemar Kasta, a former rapper born in Wrocław.
