The Prussian estates (German: Preußischer Landtag, Polish: Stany pruskie) were representative bodies of Prussia, first created by the Monastic state of Teutonic Prussia in the 14th century (around the 1370s) but later becoming a devolved legislature for Royal Prussia within the Kingdom of Poland. They were at first composed of officials of six big cities of the region; Braunsberg (Braniewo), Culm (Chełmno), Elbing (Elbląg), Danzig (Gdańsk), Königsberg (Królewiec) and Thorn (Toruń). Later, representatives of other towns as well as nobility were also included. The estates met on average four times per year, and discussed issues such as commerce and foreign relations.
Originally, the Teutonic Order created the Estate to appease the local citizens, but over time the relations between the Order and the Estates grew strained, as the Order of knights treated the local population with contempt.
Different Prussian holders of the privilege of coinage (among them the Order and some cities), actually committed to issue a Prussian currency of standardised quality, had debased the coins and expanded their circulation in order to finance the wars between Poland and Teutonic Prussia. However, this expansion disturbed the equilibrium of coins circulated to the volume of contractual obligations, only coming down to a harsh depreciation of all existing nominally fixed contractual obligations by inflating all other non-fixed prices measured by these coins, ending only once the purchasing power of every extra issued coin equalled its material and production costs.
