On 6 February 2017, the Sapphire Jubilee of Queen Elizabeth II, marking sixty-five years of her reign, occurred.
 The longest-reigning monarch in British history, Queen Elizabeth II was the first British monarch to have a sapphire jubilee.
 This Jubilee featured blue stamps from the Royal Mail, commemorative coins from the Royal Mint, and a reissue of an official 2014 portrait of Queen Elizabeth II by David Bailey.
 In this official portrait the Queen wears sapphire jewellery which she received as a wedding present from her father.
 The Jubilee also involved a gun salute at the Tower of London, a gun salute in Green Park, gun salutes in several other places around the United Kingdom, and the ringing of the bells in Westminster Abbey.
 Theresa May, the Prime Minister of the United Kingdom, congratulated Queen Elizabeth II in regard to the occasion, saying in part, "I know the nation will join with me today in celebrating and giving thanks for the lifetime of service Her Majesty the Queen has given to our country and to the Commonwealth."
The Queen Elizabeth II Golden Jubilee Medal (French: "Médaille du jubilé de la Reine Elizabeth II" ) or the Queen's Golden Jubilee Medal was a commemorative medal created in 2002 to mark the fiftieth anniversary of Elizabeth II's accession.
 The Queen Elizabeth II Golden Jubilee Medal was awarded in Canada to nominees who contributed to public life.
 The Queen's Golden Jubilee Medal was awarded to active personnel in the British Armed Forces and Emergency Personnel who had completed 5 years of qualifying service.
The coronation of Queen Elizabeth II as monarch of the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan and Ceylon took place on 2 June 1953 at Westminster Abbey.
 Elizabeth ascended the throne at the age of 25, upon the death of her father, King George VI, on 6 February 1952, and was proclaimed queen by her various privy and executive councils shortly afterwards.
 The coronation took place more than a year later because of the tradition that holding such a festival is inappropriate during the period of mourning that follows the death of a monarch and also on account of the need to make preparations for the ceremony.
 During the service, she took and subscribed an oath to, among other things, govern the peoples according to their respective laws and customs, was anointed with holy oil, presented and invested with regalia, and crowned.
The George VI and Queen Elizabeth Memorial, situated between The Mall and Carlton Gardens in central London, is a memorial to King George VI and his consort, Queen Elizabeth The Queen Mother.
 Completed in its present form in 2009, the memorial incorporates an earlier, Grade II-listed statue of George VI by William McMillan, unveiled by his daughter Queen Elizabeth II in 1955.
 The reconfigured memorial, which includes a statue of the Queen Mother by Philip Jackson, relief sculpture by Paul Day and an architectural setting by Donald Buttress and Donald Insall, was unveiled by Elizabeth II in 2009.
The Queen Elizabeth II Silver Jubilee Medal (French: "Médaille du jubilé de la reine Élisabeth II" ) was a commemorative medal created in 1977 to mark the twenty-fifth anniversary of Elizabeth II's accession in the United Kingdom, Canada, Australia, and New Zealand.
 The medal was physically identical in all realms where it was awarded, save for Canada, where it contained unique elements.
 As an internationally distributed award, the Queen Elizabeth II Silver Jubilee Medal holds a different place in each country's order of precedence for honours.
George VI (Albert Frederick Arthur George; 14 December 1895 – 6 February 1952) was King of the United Kingdom and the Dominions of the British Commonwealth from 11 December 1936 until his death.
 He was the last Emperor of India and the first Head of the Commonwealth.
The Golden Jubilee of Queen Elizabeth II was the international celebration held in 2002 marking the 50th anniversary of the accession of Elizabeth II to the thrones of seven countries, upon the death of her father, King George VI, on 6 February 1952, and was intended by the Queen to be both a commemoration of her 50 years as monarch and an opportunity for her to officially and personally thank her people for their loyalty.
 Despite the deaths of her sister, Princess Margaret, and mother, Queen Elizabeth The Queen Mother, in February and March 2002 respectively, and predictions in the media that the anniversary would be a non-event, the jubilee was marked with large-scale and popular events throughout London in June of the same year, bookended by events throughout the Commonwealth realms. Elizabeth attended all of the official celebrations as scheduled, along with her husband, the Duke of Edinburgh; over twelve months, the royal couple journeyed more than 40000 mi to the Caribbean, Australia, New Zealand, then around the United Kingdom, and wrapped up the jubilee year in Canada.
 Numerous landmarks, parks, buildings, and the like, were also named in honour of the golden jubilee and commemorative medals, stamps, and other symbols were issued.
The Diamond Jubilee of Queen Elizabeth II was a multinational celebration throughout 2012, that marked the 60th anniversary of the accession of Queen Elizabeth II on 6 February 1952.
 Queen Elizabeth is queen regnant of 16 sovereign states, known as Commonwealth realms, including the United Kingdom.
 The only other time in British history that a monarch celebrated a Diamond Jubilee was in 1897, when Queen Victoria celebrated hers.
