Брауншвейг-Вольфенбюттель
In 1432 the estates gained by the "Principality of Brunswick-Wolfenbüttel" between the Deister and Leine split away as the "Principality of Calenberg". In 1495 it was expanded around Göttingen and in 1584 went back to the Wolfenbüttel Line. In 1634, as a result of inheritance distributions, it went to the House of Luneburg residing at Celle Castle. In 1635 it was given to George, younger brother of Prince Ernest II of Lüneburg, who chose Hanover as his residence.
