Life

John IV was the elder son of Duke Nicholas V of Jägerndorf and Ratibor, who was an enemy of the Hussites. Since he and his younger brother Wenceslas when her father 's death in 1452 were not yet of age, they were initially under the tutelage of her uncle Wenceslas Ratibor († 1456 ), and her stepmother Barbara Rockenberg. After coming of age, the brothers inherited ownership to 1464 first ruled jointly. In the subsequent division of John IV Jägerndorf, Freudenthal and Loslau received while were spun for Wenzel Rybnik and Pless with Sohrau.

During the war between Bohemia and Hungary for supremacy in Bohemia supported John IV in 1469 the Bohemian King George of Podiebrad and after his death in 1471 the successor Vladislav II why he was captured in 1474 by the rival King Matthias Corvinus and forced to give him Jägerndorf. Thus it remained nurmehr Loslau, where he died in 1483.

Probably because John's sister Barbara († 1510), who was married since 1475 with Duke John IV of Auschwitz († 1495/97 ), protested to Matthias Corvinus against the shameful treatment of her brothers and the taking of their paternal inheritance, Johanns dubbed IV widow as mistress of Loslau, Rybnik and Sohrau After Matthias Corvin death in 1490 of John and Barbara Wenzel's sister dubbed as the mistress of hunters village.
