シロンスク公国
Freiwaldau/Frývaldov/Frywałdów in the Duchy of Silesia in fragmented Piast-ruled Poland, probably founded in the course of the German "Ostsiedlung", was first mentioned in 1267, when it already held the status of a town belonging to the territory of the Bishops of Wrocław. With the surrounding villages it became part of the bishops' ecclesiastical Duchy of Nysa in 1290, which later on passed under Bohemian (Czech) suzerainty.
