Odon of Poznań
By 1181, Miesko III had returned to Poland. Enlisting the aid of the Pomeranians, he wrested control over Greater Poland and Poznań from Odon. In 1182, by mutual consent, father and son agreed to divide Greater Poland between them: Odon would receive a portion of Greater Poland south of the river Obrą. Some historians believed that he remained in the Greater Poland capital until his death.
