the north this new state bordered on the County of Hoya near Nienburg and extended from there in a narrow, winding strip southwards up the River Leine through Wunstorf and Hanover where it reached the Principality of Wolfenbüttel. In 1495 it was expanded around Göttingen. In 1584 it went back to the Wolfenbüttel Line. In 1634, as a result of inheritance distributions, it went to the House of Lüneburg, before becoming an independent principality again in 1635, when it was given to George, younger brother of Prince Ernest II of Lüneburg, who chose Hanover as his Residenz. New territory was added in 1665 in the vicinity of Grubenhagen and in 1705 around the Principality of Lüneburg. In 1692 Duke Ernest Augustus from the Calenberg Line acquired the right to be a prince-elector as the Prince-Elector of Brunswick-Lüneburg. Colloquially the Electorate was also known as the Electorate of Hanover or as Kurhannover. In 1814 it was succeeded by the Kingdom of Hanover. Principality of Lüneburg The Principality of Lüneburg emerged alongside the Principality of Brunswick in 1269 when the inheritance of the Duchy was divided. After the death of Duke George William of Brunswick-Lüneburg in 1705, King George I inherited the state of Lüneburg, being both the benefactor of Georges William's 1658 renunciation in favour of his younger brother Ernest Augustus and the husband of the Duke's morganatic daughter, Sophie Dorothea, later known as the "Princess of Ahlden". It was united with the Principality of Calenberg, which had been elevated in 1692 into the Electorate. Principality of Göttingen The southernmost principality in the Duchy of Brunswick-Lüneburg stretched from Münden in the south down the River Weser to Holzminden. In the east it ran through Göttingen along the River Leine via Northeim to Einbeck. It emerged in 1345 as the result of a division of the Principality of Brunswick and was united in 1495 with Calenberg. Principality of Grubenhagen From 1291 to 1596 Grubenhagen was an independent principality, its first ruler being Henry the Admirable, son of Albert of Brunswick-Wolfenbüttel. The state lay ran from the northern part of the Solling hills and the River Leine near Einbeck and north of the Eichsfeld on and in the southwestern Harz. After being split in the course of the years into smaller and smaller principalities it Grubenhagen finally returned in 1596 to Brunswick-Wolfenbüttel.
