There was a similar situation in Greater Poland: after hearing the news of the defeat of Henry II in Legnica, Duke Przemysł I and his brother Bolesław the Pious retook the estates of Kalisz which once had been ruled by their father, the late Duke Władysław Odonic. The local nobility supported them as the true heirs to those lands. Bolesław decided to avoid a fight and renounced all his Greater Poland lands. He tried to retain some districts, such as Santok and Międzyrzecz, but in 1247 the Dukes of Greater Poland ultimately forced Bolesław to resign all his rights to lands in Greater Poland. When in 1242, Bolesław next oldest brother Mieszko died suddenly without leaving an heir, his Lubusz estates reverted to Bolesław and his younger brothers became co-rulers of the Lower Silesian lands. When his brother Henry III the White came of age in 1247, however, he and his younger brothers revolted against Bolesław and even were able to imprison him shortly thereafter. To regain freedom, Bolesław signed an agreement with Henry III, dividing the Lower Silesian lands of Legnica and Wrocław. To avoid further fragmentation, the two pledged to offer hospitality to their minor brothers, Bolesław to Konrad II, and Henry to Władysław. Bolesław, as the eldest, got first choice of the districts, and he chose the Legnica estates, possibly because of the gold discovery in the Kaczawa and Wierzbiak Rivers. Bolesław soon regretted his choice and tried to recover Wrocław. Henry III refused to surrender his new duchy, and war was inevitable. Both began preparing for battle, but didn't have adequate funds. Bolesław sought allies among the Ascanian relatives of his wife Hedwig, daughter of Count Henry I of Anhalt. Archbishop Wilbrand of Magdeburg contributed funds after Bolesław sold half of Lubusz Land to him. The German aid only gave Bolesław a temporary advantage in the war against his brother. In 1249 his younger brother and co-ruler Konrad II unexpectedly returned to the country (after concluding his studies in Paris). Bolesław proposed him as Bishop of Passau, however, Konrad refused and began to press his own claims in Silesia.
