Principality of Calenberg

The Principality of Calenberg was a dynastic division of the Welf duchy of Brunswick-Lüneburg established in 1432. Calenberg was ruled by the House of Hanover from 1635 onwards; the princes received the ninth electoral dignity of the Holy Roman Empire in 1692. Their territory became the nucleus of the Electorate of Hanover, ruled in personal union with the Kingdom of Great Britain from 1714 onwards. The principality received its name from Calenberg Castle, a residence of the Brunswick dukes.
