King George V in the context of "Marie of Romania"

The British Merchant Navy is the collective name given to British civilian ships and the Officers and Ratings that man them. In the UK, it is simply referred to as the Merchant Navy or MN. Merchant Navy vessels mostly fly the Red Ensign and the ships and ship's companies' are regulated by the Maritime and Coastguard Agency (MCA), a specialist agency of the UK Department of Transport. British merchant ships are registered under the UK or Red Ensign group ship registries. British Merchant Navy deck officers and ratings are certificated and trained according to STCW Convention and the syllabus of the Merchant Navy Training Board in maritime colleges and other training institutes around the UK.

King George V bestowed the title of "Merchant Navy" on the British merchant shipping fleets following their service in the First World War; a number of other nations have since adopted the title. Previously it had been known as the Mercantile Marine or Merchant Service, although the term "Merchant Navy" was already informally used from the 19th century.

Elizabeth II (Elizabeth Alexandra Mary; 21 April 1926 – 8 September 2022) was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death in 2022. She was queen regnant of 32 sovereign states during her lifetime and was the monarch of 15 realms at her death. Her reign of 70 years and 214 days is the longest of any British monarch, the second-longest of any sovereign state, and the longest of any queen regnant in history.

Elizabeth was born in Mayfair, London, during the reign of her paternal grandfather, King George V. She was the first child of the Duke and Duchess of York (later King George VI and Queen Elizabeth the Queen Mother). Her father acceded to the throne in 1936 upon the abdication of his brother Edward VIII, making the ten-year-old Princess Elizabeth the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In November 1947, she married Philip Mountbatten, a former prince of Greece and Denmark. Their marriage lasted 73 years until his death in 2021. They had four children: Charles, Anne, Andrew, and Edward.

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.

The Cenotaph is a war memorial on Whitehall in London, England. Designed by Sir Edwin Lutyens, it was unveiled in 1920 as the United Kingdom's national memorial to the dead of Britain and the British Empire of the First World War, was rededicated in 1946 to include those of the Second World War, and has since come to represent the Commonwealth casualties from those and subsequent conflicts. The word cenotaph is derived from Greek, meaning 'empty tomb'. Most of the dead were buried close to where they fell; thus, the Cenotaph symbolises their absence and is a focal point for public mourning. The original temporary Cenotaph was erected in 1919 for a parade celebrating the end of the First World War, at which more than 15,000 servicemen, including French and American soldiers, saluted the monument. More than a million people visited the site within a week of the parade.

Calls for the Cenotaph to be rebuilt in permanent form began almost immediately. After some debate, the government agreed and construction work began in May 1920. Lutyens added entasis (curvature) but otherwise made minimal design alterations. The Cenotaph is built from Portland stone. It takes the form of a tomb chest atop a rectangular pylon, which diminishes as it rises. Three flags hang from each of the long sides. The memorial is austere, containing almost no decoration. The permanent Cenotaph was unveiled by King George V on 11 November 1920 in a ceremony combined with the repatriation of the Unknown Warrior, an unidentified British serviceman to be interred in Westminster Abbey. After the unveiling, millions more people visited the Cenotaph and the Unknown Warrior. The memorial met with public acclaim and has largely been praised by academics, though some Christian organisations disapproved of its lack of overt religious symbolism.

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.
