Konrad X the White

Konrad X the White (Polish: Konrad X Biały) or Młodszy, ("Younger") (1420 – 21 September 1492) was a Duke of Oleśnica, Koźle, and half of both Bytom and Ścinawa during 1450–1452 (with his brother as co-rulers), since 1452 sole ruler over half of Ścinawa, during 1471–1472 sole ruler over Koźle and whole Bytom, and since 1478 sole ruler over Oleśnica.

He was the second son of Konrad V Kantner, Duke of Oleśnica by his wife Margareta.

After his father's death in 1439, Konrad X and his older brother Konrad IX the Black were excluded from the government by their uncle Konrad VII the White, who ruled until 1450, when Konrad X and Konrad IX deposed him and took over the Duchy as co-rulers; however, two years later, in 1452, they decided to divide their domains. Konrad X obtained half of Ścinawa.

During the wars between Bohemia and Hungary, he initially supported King George of Poděbrady and paid homage to him with his brother Konrad IX in 1459 in exchange for the confirmation of the possession of their father's Duchy; however, when the Hungarian troops entered in Silesia, Konrad X and Konrad IX repudiated his alliance with Bohemia and paid homage to King Matthias Corvinus.

After the death of his brother in 1471, Konrad X reunited the entire Duchy in his hands, except Oleśnica, who was leave as the Oprawa wdowia of his sister-in-law Margareta of Rawa and his niece Barbara. In view of his deep debts, he sold his Upper Silesian domains to Duke Henry I the Older of Ziębice.
