After a period of Danish occupation, Sweden finally recaptured it in 1643 and was also officially granted possession of it, together with the Archbishopric of Bremen, in the Peace of Westphalia.
Pärast Taani okupatsiooniperioodi vallutas Rootsi selle lõpuks 1643. aastal ja see anti talle Vestfaali rahuga ka ametlikult, koos Bremeni peapiiskopkonnaga.
