Royal Prussia
Royal Prussia (Polish: Prusy Królewskie; German: Königlich-Preußen or Preußen Königlichen Anteils, Kashubian: Królewsczé Prësë) or Polish Prussia[1] (Polish: Prusy Polskie;[2] German: Polnisch-Preußen)[3] was a province of the Crown of the Kingdom of Poland, which was established after the Second Peace of Thorn (1466) from territory in western Prussia which had previously been part of the State of the Teutonic Order.[4][5][6] Royal Prussia retained its autonomy, governing itself and maintaining its own laws, customs, rights and German language.[7][8]

In 1569, Royal Prussia was fully integrated into the Crown of the Kingdom of Poland and its autonomy was largely abandoned.[9] As a result, the Royal Prussian parliament was incorporated into the Sejm of the Polish–Lithuanian Commonwealth.[10] In 1772, the former territory of Royal Prussia was annexed by the Kingdom of Prussia and subsequently re-organized into the province of West Prussia. This occurred at the time of the First Partition of Poland, with other parts of the Polish–Lithuanian Commonwealth being annexed by the Russian Empire and Habsburg Austria.
