Jan I the Scholastic

Jan I the Scholastic (1308/10–1372) was duke of Oświęcim from 1324, only son of Duke Władysław and Euphrosyne of Masovia. Destined for the Church, he had held the scholastership of Kraków from 1321 but left his clerical career to succeed his father.

In February 1327 he did homage to John of Bohemia at Opava with the other Silesian Piasts, and in 1336 was forced to accept the annexation of Racibórz to Troppau. On his death in 1372 the duchy passed to his son Jan II.
