Kingdom of Galicia–Volhynia
In 1264, the Duke of Krakow, Boleslaw V the Chaste organized an expedition against Yotvingia, who were allied with Shvarn, the Duke of the Kingdom of Galicia–Volhynia. The immediate cause of the expedition was the Yotvingian raid into Polish territories in 1264 during which they ravished and plundered the country.
