Leszek I the White
At the age of twelve, Hedwig married Henry I the Bearded, son and heir of the Piast duke Boleslaus the Tall of Silesia. As soon as Henry succeeded his father in 1201, he had to struggle with his Piast relatives, at first with his uncle Duke Mieszko IV Tanglefoot who immediately seized the Upper Silesian Duchy of Opole. In 1206 Henry and his cousin Duke Władysław III Spindleshanks of Greater Poland agreed to swap the Silesian Lubusz Land against the Kalisz region, which met with fierce protest by Władysław's III nephew Władysław Odonic. When Henry went to Gąsawa in 1227 to meet his Piast cousins, he narrowly saved his life, while High Duke Leszek I the White was killed by the men of the Pomerelian Duke Swietopelk II, instigated by Władysław Odonic.
