Nakon, the Slavic lord of the castle, was described in the 10th century as a powerful Slavic ruler and compared with Miesko I. from Poland and Boleslav from Bohemia. In ancient writings the Obotrite rulers often appear in the rank of kings.
In 1167, Henry the Lion enfeoffed Pribislav (son of the Slavic ruler Niklot who fell in 1160 and a converted Christian) with his father’s land.
