List of historic titles of British monarchs
This list of titles and honours of the British monarch details the current and former titles of the sovereign of the United Kingdom of Great Britain and Northern Ireland, and its predecessor states. The present United Kingdom was formed in 1922 when the United Kingdom of Great Britain and Ireland, which had been formed in 1801 from the Kingdom of Great Britain and the Kingdom of Ireland, was partitioned to create the Irish Free State. The Kingdom of Great Britain was itself formed in 1707 from the Kingdom of England and the Kingdom  of Scotland. England and Scotland had been in a personal union since 1603, while Ireland had been in a personal union with the Kingdom of England since the elevation of the Lordship of Ireland to the status of a kingdom in 1542. Wales was gradually conquered by England in the Middle Ages, beginning with the Norman invasion of Wales and concluding with the conquests of Edward I in 1277–83. Wales was legally incorporated into England between 1535 and 1542 by King Henry VIII. The medieval monarchs of England also controlled large parts of France, particularly under the Angevin kings. Several  of the listed titles are therefore French, many held as fiefs of the French Crown rather than independently. Also represented is the English claim to the France, maintained for over 400 years before being dropped after the French Revolution. While the English claim to France was not seriously pursued after the Middle Ages, later monarchs did hold foreign titles. When William III became King alongside his wife Mary II, he maintained his Dutch titles. The Georgian kings ruled as Electors and Kings of Hanover, as well as holding the office of Arch-Treasurer of the Holy Roman Empire. These titles  lapsed when Queen Victoria succeeded to the throne. While the British Empire only gave the monarch one significant new title, that of Emperor of India, its transformation into the Commonwealth of Nations and decolonisation created many new independent states, each with a separate monarchy. Of the thirty-two realms Elizabeth II became queen of on her accession in 1952, only sixteen retain her as their monarch. All current and former Commonwealth realms are listed below. Titles held by the monarch of the United Kingdom. Commonwealth realms.
