Wertislaw

Wertislaw (c. 1130 – May or June 1164) was a son of the Obotrite prince Niklot and brother of Prince Pribislav. After Niklot was killed fighting Henry the Lion in 1160, the brothers waged a guerrilla war from Pomerania against the German vassals installed in the Obotrite lands. Defending Burg Werle in 1163, he was captured by Henry's troops.

When Pribislav renewed the revolt in summer 1164, Henry had Wertislaw hanged near Malchow. His son Nicholas I later became Lord of Mecklenburg.
