Nicholas I of Werle

Nicholas I (c. 1210–1277) was a younger son of the Mecklenburg prince Henry Borwin II and ruled as Lord of Rostock from 1229 to 1234, administering it as regent for his younger brother Henry Borwin III. In the 1234 Mecklenburg partition he received Werle.

Fighting with Duke Barnim I of Pomerania against Brandenburg, he lost Perleberg, Wesenberg and Penzlin but secured Parchim, Plau and Goldberg after his brother Pribislaw died. He founded the towns of Penzlin and Röbel. In 1275 he mediated a quarrel between his sons. After his death they divided Werle between them.
