Elizabeth II (Elizabeth Alexandra Mary; born 21 April 1926) is the Queen of 16 of the 53 member states in the Commonwealth of Nations. She is Head of the Commonwealth and Supreme Governor of the Church of England.

MM

Upon her accession on 6 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.

MM

Her coronation service the following year was the first to be televised. From 1956 to 1992, the number of her realms varied as territories gained independence and some realms became republics. Today, in addition to the first four of the aforementioned countries, Elizabeth is Queen of Jamaica, Barbados, the Bahamas, Grenada, Papua New Guinea, Solomon Islands, Tuvalu, Saint Lucia, Saint Vincent and the Grenadines, Belize, Antigua and Barbuda, and Saint Kitts and Nevis.

MM

From 10 September 2015, she became the

longest reigning British head of state and the

longest reigning female monarch in history,

surpassing Queen Victoria.

MM

Elizabeth was born in London as the elder daughter of the Duke and Duchess of York, later King George VI and Queen Elizabeth, and educated privately at home. Her father acceded to the throne on the abdication of his brother Edward VIII in 1936, from which time she was the heir presumptive.

MM

She began to undertake public duties during

the Second World War, in which she served in

the Auxiliary Territorial Service.

MM

In 1947, she married Philip, Duke of Edinburgh, with whom she has four children: Charles, Anne, Andrew, and Edward.

MM

Elizabeth's many historic visits and meetings include a state visit to the Republic of Ireland, the first state visit of an Irish president to the United Kingdom, and reciprocal visits to and from the Pope.

MM

She has seen major constitutional changes, such as devolution in the United Kingdom, Canadian patriation, and the decolonisation of Africa. She has also reigned through various wars and conflicts involving many of her realms.

MM

Elizabeth has occasionally faced republican sentiments and severe press criticism of the royal family, but support for the monarchy and her personal popularity remain high.

MM

Second World War

During the war, many of London's children were evacuated to avoid the frequent aerial bombing. The suggestion by senior politician Lord Hailsham that the two princesses should be evacuated to Canada was rejected by Elizabeth's mother, who declared:

MM

"The children won't go without me. I won't leave without the King. And the King will never leave."

MM

Princesses Elizabeth and Margaret stayed at Balmoral Castle, Scotland, until Christmas 1939, when they moved to Sandringham House, Norfolk. From February to May 1940, they lived at Royal Lodge, Windsor, until moving to Windsor Castle, where they lived for most of the next five years. In 1940, the 14-year-old Elizabeth made her first radio broadcast during the BBC's Children's Hour, addressing other children who had been evacuated from the cities. She stated:

MM

"We are trying to do all we can to help our gallant sailors, soldiers and airmen, and we are trying, too, to bear our share of the danger and sadness of war. We know, every one of us, that in the end all will be well."

MM

In February 1945, she joined the Women's Auxiliary Territorial Service as an honorary second subaltern with the service number of 230873. She trained as a driver and mechanic and was promoted to honorary junior commander five months later.

MM

At the end of the war in Europe, on Victory in Europe Day, Princesses Elizabeth and Margaret mingled anonymously with the celebratory crowds in the streets of London. Elizabeth later said in a rare interview,

MM

"We asked my parents if we could go out and see for ourselves. I remember we were terrified of being recognised ... I remember lines of unknown people linking arms and walking down Whitehall, all of us just swept along on a tide of happiness and relief."

MM

In early 1952, Elizabeth and Philip set out for a tour of Australia and New Zealand by way of Kenya. They had just returned to their Kenyan home, Sagana Lodge, after a night spent at Treetops Hotel, when word arrived of the death of the King. Philip broke the news to the new Queen. She was proclaimed queen throughout her realms and the royal party hastily returned to the United Kingdom. She and the Duke of Edinburgh moved into Buckingham Palace.

MM

With Elizabeth's accession, it seemed probable that the royal house would bear her husband's name, becoming the House of Mountbatten, in line with the custom of a wife taking her husband's surname on marriage. Winston Churchill and Elizabeth's grandmother, Queen Mary, favoured the retention of the House of Windsor, and so on 9 April 1952 Elizabeth issued a declaration that Windsor would continue to be the name of the royal house.

MM

The Coronation ceremony took place on June 2nd 1953  in Westminster Abbey and was televised for the first time. Elizabeth's coronation gown was commissioned from Norman Hartnell and embroidered on her instructions with the floral emblems of Commonwealth countries: English Tudor rose; Scots thistle; Welsh leek; Irish shamrock; Australian wattle; Canadian maple leaf; New Zealand silver fern; South African protea; lotus flowers for India and Ceylon; and Pakistan's wheat, cotton, and jute.

MM

In 1957, she made a state visit to the United States, where she addressed the United Nations General Assembly on behalf of the Commonwealth. On the same tour, she opened the 23rd Canadian Parliament, becoming the first monarch of Canada to open a parliamentary session.

MM

Two years later, solely in her capacity as Queen of Canada, she revisited the United States and toured Canada. In 1961, she toured Cyprus, India, Pakistan, Nepal, and Iran.

On a visit to Ghana the same year, she dismissed fears for her safety, even though her host, President Kwame Nkrumah, who had replaced her as head of state, was a target for assassins. Harold Macmillan wrote...

MM

"The Queen has been absolutely determined all through ... She is impatient of the attitude towards

her to treat her as ... a film star ... She has indeed

'the heart and stomach of a man' ... She loves her

duty and means to be a Queen."

MM

Before her tour through parts of Quebec in 1964, the press reported that extremists within the Quebec separatist movement were plotting Elizabeth's assassination. No attempt was made, but a riot did break out while she was in Montreal; the Queen's "calmness and courage in the face of the violence" was noted.

MM

The 1960s and 1970s saw an acceleration in the decolonisation of Africa and the Caribbean. Over 20 countries gained independence from Britain as part of a planned transition to self-government.

MM

In 1977, Elizabeth marked the Silver Jubilee of her accession. Parties and events took place throughout the Commonwealth, many coinciding with her associated national and Commonwealth tours. The celebrations re-affirmed the Queen's popularity.

MM

In 1991, in the wake of victory in the Gulf War, Elizabeth became the first British monarch to address a joint meeting of the United States Congress.

MM

In a speech on 24 November 1992, to mark the 40th anniversary of her accession, Elizabeth called 1992 her 'annus horribilis', meaning horrible year.
