 James Louis Sobieski died of a stroke on 19 December 1737 in Żółkiew, Poland and is buried there.His oldest surviving daughter Maria Karolina, inherited his vast land holdings which included 11 cities and 140 villages.The connection to the Polish state which Sobieski's rule brought to Oława set this part of Lower Silesia on a different trajectory, and thanks to it the Polish language was preserved here long after James' death in 1737.
