Elizabeth II was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death in 2022. She was queen regnant of 32 sovereign states during her lifetime and was the monarch of 15 realms at her death. Her reign of 70 years and 214 days is the longest of any British monarch, the second-longest of any sovereign state, and the longest of any queen regnant in history.

Charlotte of Mecklenburg-Strelitz was Queen of Great Britain and Ireland as the wife of King George III from their marriage on 8 September 1761 until her death in 1818. The Acts of Union 1800 unified Great Britain and Ireland into the United Kingdom of Great Britain and Ireland. As George's wife, she was also Electress of Hanover until becoming Queen of Hanover on 12 October 1814. Charlotte was Britain's longest-serving queen consort, serving for 57 years and 70 days.
