(21 April 1926 - 8 September 2022 )
Elizabeth was born at 02:40 (GMT) on 21 April 1926, during the reign of her paternal grandfather, King George V. Her father, the Duke of York (later King George VI), was the second son of the King. Her mother, the Duchess of York (later Queen Elizabeth The Queen Mother), was the youngest daughter of Scottish aristocrat Claude Bowes-Lyon, 14th Earl of Strathmore and Kinghorne, at whose London home (17 Bruton Street, Mayfair) she was delivered by Caesarean section. She was baptised by the Anglican Archbishop of York, Cosmo Gordon Lang, in the private chapel of Buckingham Palace on 29 May, and named Elizabeth after her mother; Alexandra after her paternal great-grandmother, who had died six months earlier; and Mary after her paternal grandmother. Called "Lilibet" by her close family, based on what she called herself at first, she was cherished by her grandfather, George V, whom she affectionately called "Grandpa England"
Elizabeth met her future husband, Prince Philip of Greece and Denmark, in 1934 and again in 1937. They were second cousins once removed through King Christian IX of Denmark and third cousins through Queen Victoria. After meeting for the third time at the Royal Naval College in Dartmouth in July 1939, Elizabeth—though only 13 years old—said she fell in love with Philip, and they began to exchange letters. She was 21 when their engagement was officially announced on 9 July 1947.
George VI's health declined during 1951, and Elizabeth frequently stood in for him at public events. When she toured Canada and visited President Harry S. Truman in Washington, D.C., in October 1951, her private secretary, Martin Charteris, carried a draft accession declaration in case of the King's death while she was on tour. In early 1952, Elizabeth and Philip set out for a tour of Australia and New Zealand by way of Kenya. On 6 February 1952, they had just returned to their Kenyan home, Sagana Lodge, after a night spent at Treetops Hotel, when word arrived of the death of George VI and Elizabeth's consequent accession to the throne with immediate effect. Philip broke the news to the new queen. She chose to retain Elizabeth as her regnal name; thus she was called Elizabeth II
On 8 September 2022, Buckingham Palace announced that the Queen was under medical supervision at Balmoral Castle after doctors expressed concern. The statement read, "Following further evaluation this morning, the Queen's doctors are concerned for Her Majesty's health and have recommended she remain under medical supervision. The Queen remains comfortable and at Balmoral." The Queen's four children, along with her daughters-in-law and grandsons Prince William and Prince Harry, travelled to Balmoral. Her death was confirmed that evening, setting in motion Operation London Bridge and, because she died in Scotland, Operation Unicorn.
