The Prussian Confederation was an organization formed on 21 February 1440 at Kwidzyn by a group of 53 nobles and clergy and 19 cities in Prussia, to oppose the arbitrariness of the Teutonic Knights. It was based on an earlier similar organization, the Lizard Union established in 1397 by the nobles of Chełmno Land.
