Jan II of Oświęcim

Jan II of Oświęcim (Polish: Jan II oświęcimski) (c. 1344/51 – 19 February 1376) was a Duke of Oświęcim since 1372 until his death.

He was the only son of Jan I the Scholastic, Duke of Oświęcim, by his unknown first wife.

Jan II took the full government over Oświęcim after his father's death on 29 September 1372. This was subsequently confirmed by the King Wenceslaus IV of Bohemia on 9 October of that year. The new Duke, however, had to accept named Przemysław I Noszak, Duke of Cieszyn his sole heir. In this case, was ignored the fact that Jan II had already a namesake son. Perhaps, just as in the case of Jan I, the future Jan III was originally destined for a Church career.

During almost all his rule, Jan II had considerable financial difficulties, because he was committed to repay the sum illegally obtained by his father from the Scholastic of Krakow.

Little is known about the rest of Jan II's reign. He died in 1376 (the exact date varied according to the sources: 19 February, 8 October and even one year before, on 1 June 1375) and was buried in the Dominican church of Oświęcim.

By 1366, Jan II married with Hedwig (b. ca. 1351 – d. by 30 January 1385), daughter of Ludwik I the Fair, Duke of Brzeg. They had three children:
