Kingdom of Hanover
The Kingdom of Hanover () was a kingdom in northwest Germany. It was created in October 1814 by the Congress of Vienna. It came after the Electorate of Hanover (officially the Electorate of Brunswick-Lüneburg). It joined 38 other countries in the German Confederation in June 1815. The kingdom was ruled by the House of Hanover. This was a branch of the House of Welf. It was in personal union with Great Britain since 1714. Usually a viceroy controlled Hanover. This was because its monarch lived in London. The viceroys were usually younger members of the British royal family.
