Wenceslaus of Krosno (; 1391 â before 4 February 1431) was a Duke of à »agaà Â-Gà Âogów during 1397âÂÂ1412 (as co-ruler with his brother), ruler over Gà Âogów (with his brothers as co-rulers) during 1412âÂÂ17, and ruler over Krosno Odrzaà Âskie, à Âwiebodzin and Bytnica after 1417.
He was the fourth and youngest son of Henry VIII the Sparrow, Duke of Gà Âogów by his wife Katharina, daughter of Duke Wà Âadysà Âaw of Opole.
After his father's early death in 1397, Wenceslaus and his older brothers succeeded him as co-rulers of the lands, but remained under the care of their mother and settled their residence in Koà ¼uchów, which, together with Zielona Góra, was her dower. The official guardianship of the young princes and the regency of the Duchy were held by Duke Rupert I of Legnica until 1401, when Wenceslaus's older brother Jan I attained his majority and assumed the government of the Duchy and the custody of his younger brothers by himself.
In 1412, the formal division of their Duchy occurred: Jan I retained à »agaà Â; Wenceslaus, together with his brother Henry IX the Older and Henry X Rumpold, obtained Gà Âogów as co-rulers. In 1417, another duchy was divided, this time the Duchy of Gà Âogów. Henry IX the Older and Henry X Rumpold retained Gà Âogów and Szprotawa, while Wenceslaus received the towns of Krosno Odrzaà Âskie, à Âwiebodzin and Bytnica.
Wenceslaus was a vassal of the Emperor Sigismund, taking part in his coronation as King of Bohemia in Prague on 28 July 1420, three years later in the congress of Pressburg (now Bratislava), and finally in the war against the Hussites.
Wenceslaus died around 1431, after accidentally shooting himself while handling a gun without precaution. He died unmarried and childless. After his death, all his lands were inherited by his brother, Henry IX.
