Reformation and PolandKaliningrad, Kaliningrad Oblas
The teachings of Martin Luther were accepted most readily in the regions with strong German connections: Silesia, Greater Poland, Pomerania and Prussia. In Danzig (Gdańsk) in 1525 a lower-class Lutheran social uprising took place and was bloodily subdued by Sigismund I; after the reckoning he established a representation for the plebeian interests as a segment of the city government. Königsberg and the Duchy of Prussia under Albrecht Hohenzollern became a strong center of Protestant propaganda dissemination affecting all of northern Poland and Lithuania. Sigismund quickly reacted against the "religious novelties", issuing his first related edict in 1520, banning any promotion of the Lutheran ideology, or even foreign trips to the Lutheran centers. Such attempted (poorly enforced) prohibitions continued until 1543.
