Principality of Calenberg
In 1705 the Lunenburg-Celle line was extinct and the principality inherited by Duke George Louis of Brunswick and Lunenburg (Calenberg), ruling the Principality of Calenberg, which managed to be upgraded as Electorate of Brunswick and Lunenburg, colloquially named after its capital Electorate of Hanover, in 1708. In 1714 Prince-Elector George Louis ascended the British throne as George I, ruling Hanover and Britain in personal union.
