 The Galician boyars (nobility) subsequently attempted to rule the state themselves.Fearing subjugation by Władysław I, they apparently sought the protection of the Tatars.But soon more conservative elements amongst the boyars gained the upper hand, and the Galician throne was given to the Mazovian Duke Boleslaw Trojdenowicz (who was related to the deceased royal brothers through the marriage of his father Trojden I of Masovia to their sister Maria).
