Summary
Ernest Augustus (German: Ernst August; 5 June 1771 – 18 November 1851) was king of Hanover from 20 June 1837 until his death. As the fifth son of King George III of the United Kingdom and Hanover, initially he seemed unlikely to become a monarch, but none of his elder brothers had a legitimate son. Ernest succeeded in Hanover under Salic law, which debarred women from the succession, ending the personal union between Britain and Hanover that had begun in 1714.
