 In October 1277, lands destined for his younger brother Casimir II were invaded by Lithuanians, who, after the abduction of prisoners and seizure of loot, freely returned home.This was a result of being the proteges of Bolesław V the Chaste, who at this time was in the opposite political camp (proczeskim) from Konrad II, Duke of Mazovia, through whose land the Lithuanian invasion passed.Two years later, in 1279, Władysław I Łokietek was considered to be one of the contenders to succeed in Lesser Poland after the death of Bolesław V the Chaste, according to the Hypatian Codex.
