Greifen
Ernst Bogislaw began studying at the University of Greifswald in 1634. His uncle, Bogislaw XIV, Duke of Pomerania, granted him lordship over Naugard (Nowogard) and Massow (Maszewo). When Bogislaw XIV, the last duke of the House of Pomerania, died in 1637, Ernst Bogislaw inherited the late ruler's personal possessions.
