Bolesław IV the Curly
The first major conflict with the high duke took place during 1140–1141, when his younger half-brothers Bolesław IV the Curly and Mieszko III together with their mother but without Władysław's knowledge divided between them the lands of Łęczyca, which were held only as a wittum by Bolesław's widow Salomea for life and should revert to Władysław's Seniorate Province upon her death.
