Royal Prussia (Polish: Prusy Królewskie; German: Königlich-Preußen or Preußen Königlichen Anteils, Kashubian: Królewsczé Prësë) or Polish Prussia (Polish: Prusy Polskie; German: Polnisch-Preußen) became a province of the Crown of the Kingdom of Poland, which was annexed following the Second Peace of Thorn (1466) from territory in Pomerelia and western Prussia which had been part of the State of the Teutonic Order. Royal Prussia retained its autonomy, governing itself and maintaining its own laws, customs, rights and German language for the Germans (mainly in urban areas) and Polish language for the Polish (mainly in rural areas). The inhabitants, from various ethnic groups, had a strong local identity and called themselves 'Prussians'. In 1569, Royal Prussia was fully integrated into the Crown of the Kingdom of Poland and its autonomy was largely abolished. As a result, the Royal Prussian parliament was incorporated into the Sejm of the Polish–Lithuanian Commonwealth. In 1772 and 1793, after the first and second partition of Poland, the former territory of Royal Prussia was recovered 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. Source: Wikipedia (en)
