Elizabeth II
Queen of the United Kingdom from 1952 until her death in 2022 — seventy years on the throne, longer than any British monarch before her. Under her the empire dissolved and the Commonwealth took shape, and fifteen prime ministers came and went, from Churchill to Truss.
Born in London on 21 April 1926 at 02:40 British Summer Time, which that year began on 18 April. The hour was announced in the court bulletin on the day of her birth — a case where the time is known from an official record made at once.
