Mary of Teck was Queen of the United Kingdom and the British Dominions from 1910 until 1936 as the wife of King George V. She was concurrently Empress of India.
Born and raised in the United Kingdom, her parents were Francis, Duke of Teck, a German nobleman, and Princess Mary Adelaide of Cambridge, who was a granddaughter of King George III and a minor member of the British royal family. She was informally known as "May", after the month of her birth.
At the age of 24, she was betrothed to her second cousin once removed Prince Albert Victor, Duke of Clarence and Avondale, the eldest son of the Prince of Wales, but six weeks after the announcement of the engagement, he died unexpectedly during an influenza pandemic. The following year, she became engaged to Albert Victor's only surviving brother, George, who subsequently became king. Before her husband's accession, she was successively Duchess of York, Duchess of Cornwall, and Princess of Wales.
As queen consort from 1910, she supported her husband through the First World War, his ill health, and major political changes arising from the aftermath of the war.
