Queen Elizabeth II

Elizabeth II was Queen of the United Kingdom and the other Commonwealth realms.

Elizabeth was born in London, the first child of the Duke and Duchess of York, later King George VI and Queen Elizabeth, and she was educated privately at home. Her father ascended the throne on the abdication of his brother King Edward VIII in 1936, from which time she was the heir presumptive. She began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In 1947, she married Philip, Duke of Edinburgh, a former prince of Greece and Denmark, with whom she had four children: Charles, Prince of Wales; Anne, Princess Royal; Prince Andrew, Duke of York; and Prince Edward, Earl of Wessex.

When her father died in February 1952, Elizabeth became head of the Commonwealth and queen regnant of seven independent Commonwealth countries: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon. She reigned as a constitutional monarch through major political changes, such as devolution in the United Kingdom, Canadian patriation, and the decolonization of Africa. Between 1956 and 1992, the number of her realms varied as territories gained independence, and as realms, including South Africa, Pakistan, and Ceylon (renamed Sri Lanka), became republics. Her many historic visits and meetings included a state visit to the Republic of Ireland and visits to or from five popes. Significant events included her coronation in 1953 and the celebrations of her Silver, Golden, and Diamond Jubilees in 1977, 2002, and 2012, respectively. In 2017, she became the first British monarch to reach a Sapphire Jubilee. She was the longest-lived and longest-reigning British monarch. She was the longest-serving female head of state in world history, and the world's oldest living monarch, longest-reigning monarch, and oldest and longest-serving head of state.
