BJJ Academies in Masovia.

Masovia (Mazowieckie) — the Polish voivodeship containing Warsaw — anchors the country's capital BJJ scene. Warsaw is one of Poland's two main BJJ centers (alongside Poznań, where Adam Wardziński's Checkmat academy operates).

Warsaw's BJJ surface includes Dragon's Den Fight Club Warsaw, which runs BJJ alongside MMA, submission fighting, freestyle wrestling, Muay Thai, and self-defense, and a deepening cluster of city academies running gi and no-gi. The Polish BJJ scene runs nationally on the strength of 300+ black belts — Adam Wardziński, the first Polish IBJJF World Champion and first European IBJJF Grand Slam winner, leads that pack.
