George I (George Louis; German: Georg Ludwig) was King of Great Britain and Ireland from 1 August 1714 until his death, and ruler of the Duchy and Electorate of Brunswick-Lüneburg (Hanover) in the Holy Roman Empire from 1698.
The royal style of King George I was "By the Grace of God, King of Great Britain, France and Ireland, Defender of the Faith, Archtreasurer and Prince-Elector of the Holy Roman Empire, Duke of Brunswick-Luneburg".
The title King of Gibraltar continues to be used by Spanish monarchs even though the territory was ceded to the Crown of Great Britain in perpetuity under the terms of the Treaty of Utrecht of 1713. The continued use of the title thus emphasizes a Spanish viewpoint that the British monarch merely has possession of Gibraltar, rather than sovereignty over it. The United Kingdom, by contrast, takes the position that the treaty transferred sovereignty as well as possession. It was customary for titles and arms of conquered territories to be omitted from British regnal claims. The title and arms were thus never claimed by the British monarchy.
