Mary of Teck in the context of "Queen Elizabeth The Queen Mother"

Elizabeth Angela Marguerite Bowes-Lyon (4 August 1900 – 30 March 2002) was Queen of the United Kingdom and the Dominions of the British Commonwealth from 11 December 1936 to 6 February 1952 as the wife of King George VI. She was also the last Empress of India from 1936 until the British Raj was dissolved on 15 August 1947. After her husband died, she was officially known as Queen Elizabeth the Queen Mother to avoid confusion with her daughter Queen Elizabeth II.

Born into a family of British nobility, Elizabeth came to prominence in 1923 when she married Prince Albert, Duke of York, the second son of King George V and Queen Mary. The couple and their daughters, Elizabeth and Margaret, embodied traditional ideas of family and public service. As Duchess of York, Elizabeth undertook a variety of public engagements and became known for her consistently cheerful countenance.

Edward VIII (Edward Albert Christian George Andrew Patrick David; 23 June 1894 – 28 May 1972), later known as the Duke of Windsor, was King of the United Kingdom and the British Dominions, and Emperor of India, from 20 January 1936 until his abdication in December of the same year.

Edward was born during the reign of his great-grandmother Queen Victoria as the eldest child of the Duke and Duchess of York, later King George V and Queen Mary. He was created Prince of Wales on his 16th birthday, seven weeks after his father succeeded as king. As a young man, Edward served in the British Army during the First World War and undertook several overseas tours on behalf of his father. The Prince of Wales gained popularity due to his charm and charisma, and his fashion sense became a hallmark of the era. After the war, his conduct began to give cause for concern; he engaged in a series of sexual affairs that worried both his father and the British prime minister, Stanley Baldwin.

Princess Marina of Greece and Denmark (Greek: Μαρίνα; 13 December [O.S. 30 November] 1906 – 27 August 1968), later Duchess of Kent, was a Greek and Danish princess by birth and a British princess by marriage. A granddaughter of King George I of Greece and Queen Olga, she was the daughter of Prince Nicholas of Greece and Denmark and Grand Duchess Elena Vladimirovna of Russia. In 1934, she married Prince George, Duke of Kent, the fourth son of King George V and Queen Mary. They had three children: Prince Edward, Princess Alexandra, and Prince Michael. She was widowed in 1942, when her husband was killed in a plane crash while on active service, and remained active in royal duties throughout her later life, attending public engagements across the Commonwealth, including the independence celebrations for Ghana and Botswana. She died in 1968, aged 61.

The Delhi Durbar (lit. "Court of Delhi") was the imperial mass assembly organized by the British Raj at Coronation Park, Delhi, India, to mark the accession of an Emperor or Empress of India. The ceremonial name was derived from the Persian term, durbar (royal court). Also known as the Imperial Durbar, it was held three times, in 1877, 1903, and 1911, at the height of the British Empire. The 1911 Durbar was the only one that a sovereign, George V, attended; at the earlier Durbars, the monarch was represented by their viceroy. A Durbar was contemplated in 1937 or 1938 for George VI, the last emperor, but was postponed. The impetus for the Durbar expired when India and Pakistan became independent countries after World War II.

Prince Albert Victor, Duke of Clarence and Avondale (Albert Victor Christian Edward; 8 January 1864 – 14 January 1892), was the eldest child of the Prince and Princess of Wales (later King Edward VII and Queen Alexandra). From the time of his birth, he was second in the line of succession to the British throne, but did not become king or Prince of Wales because he died before both his father and paternal grandmother Queen Victoria.

Albert Victor was known to his family, and many later biographers, as "Eddy". When he was young, he travelled the world extensively as a Royal Navy cadet, and as an adult, he joined the British Army, but did not undertake any active military duties. After two unsuccessful courtships, he became engaged to be married to his second cousin once removed Princess Victoria Mary of Teck in late 1891. A few weeks later, he died during a major pandemic. Mary later married his younger brother, the future King George V.

On 6 July 1893, Prince George, Duke of York (later King George V), and Princess Victoria Mary of Teck (later Queen Mary) were married at the Chapel Royal, St. James's Palace, in London, England.
