In page Henry III, Duke of Głogów:
"One year later Henry III participated in the great Battle on the Marchfeld (26 August 1278), where King Ottokar II was defeated and killed. In the same year Henry III was forced to make a division of his lands between his brothers: he retained the main cities of the Duchy —Głogów, Bytom Odrzański and Kożuchów—; Konrad II the Hunchback obtained Ścinawa and Przemko received Żagań and Nowogród Bobrzański; soon after Konrad II went to study in Bologna, and Henry IV Probus took his lands in his name; with this, the ruler of Wroclaw showed his intentions to stretch his sovereignty over all the other Głogów princes and Silesian rulers.
