Victoria (Alexandrina Victoria) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death. From 1 May 1876, she used the additional title of Empress of India.
The royal styles used by Queen Victoria were:
1837 – 1876 "By the Grace of God, of the United Kingdom of Great Britain and Ireland Queen, Defender of the Faith".
1876 – 1901 "By the Grace of God, of the United Kingdom of Great Britain and Ireland Queen, Defender of the Faith, Empress of India".
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.
