Her son Charles, the former Prince of Wales, is now King Charles III, as the world grieves his mother, Britain's longest-reigning monarch.
All Her Majesty's children had rushed to Balmoral yesterday after doctors became 'concerned' for her health.
Hours later she died, surrounded by her family.
At 6.30pm her death was confirmed.
A Buckingham Palace spokesman said:
'The Queen died peacefully at Balmoral this afternoon. The King and The Queen Consort will remain at Balmoral this evening and will return to London tomorrow'.
The Queen's death will see Britain and her Commonwealth realms enter into a ten-day period of mourning as millions of her subjects in the UK and abroad come to terms with her passing. Her coffin will be moved to London on the royal train via Edinburgh before she lies in state in Westminster Hall in the Houses of Parliament for four days. Hundreds of thousands of people will be able to pay their respects.
The state funeral is expected take place at Westminster Abbey in central London on Monday, September 19, which will be attended by her bereft family as well as 2,000 heads of state, prime ministers and presidents, European royals and key figures from public life around the globe.
And as her son accedes to the throne, there will also be a celebration of her historic 70-year reign that saw her reach her Platinum Jubilee this year - a landmark unlikely to be reached again by a British monarch. Charles, who will reign as King Charles III, said today: '
The death of my beloved mother, Her Majesty The Queen, is a moment of the greatest sadness for me and all members of my family.
'We mourn profoundly the passing of a cherished sovereign and a much-loved mother. I know her loss will be deeply felt throughout the country, the Realms and the Commonwealth, and by countless people around the world. 'During this period of mourning and change, my family and I will be comforted and sustained by our knowledge of the respect and deep affection in which the Queen was so widely held.' Tributes are already pouring in for Her Majesty, to many the greatest Briton in history and undoubtedly the most famous woman on earth. To billions around the world she was the very face of Britishness.
Liz Truss hailed the Queen, who appointed her as the 15th Prime Minister of her reign on Tuesday, said: 'Queen Elizabeth II was the rock on which modern Britain was built. Our country has grown and flourished under her reign. Britain is the great country it is today because of her.'
US President Joe Biden and First Lady Jill Biden said the Queen was 'more than a monarch' and that she 'defined an era'.
A White House statement said:
'In a world of constant change, she was a steadying presence and a source of comfort and pride for generations of Britons, including many who have never known their country without her. She, in turn, dedicated her whole life to their service'.
While this was ongoing, a Pennsylvania-based Nigerian professor, Uju Anya, on Thursday, traded words with Amazon founder, Jeff Bezos over Queen Elizabeth II.
Uju made some scathing and unbecoming remarks about the British monarch after news broke of her demise.
In a now deleted tweet, she wrote; ”I heard the chief monarch of a thieving raping genocidal empire is finally dying. May her pain be excruciating.”
Bezos, who came across her tweet and thought it was distasteful, made reference to her being a lecturer that is supposed to make the world a better place.
He quoted her tweet and wrote; ‘This is someone supposedly working to make the world better? I don’t think so. Wow.”
But in response, Uju rained insults on the Forbes billionaire, both in Igbo and English language.
”Otoro gba gbue gi. May everyone you and your merciless greed have harmed in this world remember you as fondly as I remember my colonizers,” she tweeted.
Ex-England Footballer Trevor Sinclair and Nigerian Afro Beat artist and saxophonist, Seun Anikulapo-Kuti also sparked outrage over comments after the Queens death.
“Racism was outlawed in England in the 60's & it's been allowed to thrive so why should black and brown mourn!!”
The former footballer has since deactivated his Twitter account.
Seun Anikulapo-Kuti wrote:
May Queen Elizabeth's soul rest in perfect peace- AMEN.
