Легницкое княжество
On 12 January 1409, after the death of his last surviving brother Rupert I without male issue, Wenceslaus II became the sole heir of the Duchy of Legnica; two months later, on 19 March, he designated as his heirs the brothers Henry IX and Louis II of Brieg, grandsons of Louis I the Fair. In 1413, Wenceslaus managed to unite the Diocese of Breslau and the Duchy of Liegnitz in one state, trying in that way to save the title of Bishop to his successors.
