Fürstentum Neisse
Bolko's attempts to gain the Duchy of Nysa failed, nevertheless he occupied Paczków and acquired Chojnów from Duke Henry III of Głogów. After his death in 1301, his sons finally divided their territories in 1312: the lands around Świdnica and Ziębice were again split off into separate duchies, while Jawor was ruled by Duke Henry I. After his death in 1346, the duchy was reunited with Świdnica under the rule of his nephew Bolko II the Small.
