Nicholas II of Opava was a member of the Opava branch of the Bohemian noble
Přemyslovci family. His parents were Duke
Nicholas I of Opava, who had held Opava since 1269, and Adelheid of
Habsburg, a niece of King
Rudolf I. He was a supporter of King
John of Luxembourg of Bohemia, who gave him Opava as a
fief in 1318 and at the same time raised it to an independent duchy. He moved the ducal residence from
Hradec nad Moravicí () to
Opava (). Also in 1318, he married with Anna, the only sister of Duke
Leszek of Ratibór. Since Leszek left no offspring, the Duchy of Ratibór reverted to the
Bohemian Crown after Leszek death in 1336. King John gave it to his loyal
vassal Nicholas II in 1337. With his dual power base in Opava and Ratibór, Nicholas became one of the most powerful princes in the upper
Oder area. With the acquisition by Nicholas, Ratibór came under a foreign ruler and due to the personal union, Opava became more oriented towards
Silesia. In 1337, the princes of
Opole also claimed Ratibór; King John sold them the Moravian town of
Prudnik () instead. In a document dated 1350, Nicholas II is mentioned as Burgrave of
Kłodzko. In 1355 he had to give up
Koźle and
Gliwice, which had been transferred to Duke Leszek. == Marriage and issue ==
