Kingdom of Hanover years of George III's reign and the reigns of kings George IV and William IV from 1816 to 1837, was Adolph Frederick, George III's youngest surviving son. When Queen Victoria succeeded to the British throne in 1837, the 123-year personal union of Great Britain and Hanover ended. Salic law operated in Hanover, excluding accession to the throne by a female while any male of the dynasty survived; thus instead of Victoria, her uncle in the male-line of the House of Hanover, Ernest Augustus, now the eldest surviving son of George III, succeeded to the throne of the new kingdom as
Inauguration of the Dutch monarch and invested in Amsterdam at a public joint session of the two houses of the States General. The monarch may not exercise the royal prerogative until reaching the age of 18. Inauguration is strictly ceremonial as the successor to the throne instantly becomes the new monarch at the moment the former monarch dies or abdicates. The last Dutch monarch to rule until his death was William III in 1890. His successor was his daughter, Wilhelmina; however, she was not inaugurated until her coming of age in 1898. Her mother Emma of Waldeck and Pyrmont was regent from 1890 to 1898.
