 Władysław I inherited a small portion of his father's domain, but his dominion grew as some of his brothers died young.He unsuccessfully tried to incorporate the Duchy of Krakow (the Seniorate Province) in 1289, following the death of his half-brother Leszek II the Black and the withdrawal from contention of his ally Bolesław II of Masovia.After a period in exile during the rule of Wenceslaus II, Władysław regained several duchies and then Krakow in 1306 when Wenceslaus III was murdered.
