カレンベルク侯領
The city of Hanover was largely independent of Welf territorial lordship, even though it was not formally a free imperial city. Not until George of Calenberg, who had been a successful general in the Thirty Years War, chose the city as his "Residenz" in 1636 could Hanover also be viewed as part of the Principality of Calenberg. Calenberg Castle was demolished and slighted between 1692 and 1694.
