Władysław the Hunchback
Władysław the Hunchback (c. 1303–1352) was a Piast prince, the son of Siemowit of Dobrzyń and Anastasia of Halych–Volhynia. He ruled Dobrzyń from 1312, and in 1327 exchanged it with his uncle Władysław I the Elbow-high for the Duchy of Łęczyca amid Teutonic Order pressure.
The 1343 Treaty of Kalisz returned Dobrzyń to him. Childless, he died in 1351 or 1352, and his lands reverted to the Polish crown.
