“The Sovereign and Spirit of Britain Dies at 96”, The New York Times

The new king said in a statement, “We mourn profoundly the passing of a cherished sovereign and much-loved mother. I know her loss will be deeply felt throughout the country, the realms and Commonwealth, and by countless people around the world.”

Tributes also poured in from around the world. President Biden and his wife, Jill, said in a statement that the queen was “the first British monarch to whom people all around the world could feel a personal and immediate connection.” Emmanuel Macron, the president of France, said she had embodied the “continuity and unity” of the British nation for over 70 years.

As dusk fell on London, large crowds began to gather in front of Buckingham Palace, echoing the mass demonstrations of grief after the news that Princess Diana had been killed in a car accident in Paris in 1997.

Others lingered on street corners, staring at news updates on their phones. In South London, Tiana Krahn alluded to Britain’s mounting problems, saying the queen’s death came at the “worst possible moment in history.”

“We are going to see some crazy falling apart,” she added. “There was something solid about that, about knowing that she was in charge.”

Many of those who crowded pubs on Thursday evening described being at a loss as to how they should feel. “I don’t think people around the world realized just how brilliant she was,” said one customer, Jeff Nightingill. “It’s like losing your grandmother. My wife will be in tears when I get home tonight.”

The queen’s death had none of the awful suddenness of Diana’s. The stark language in the palace’s statement on Thursday was highly unusual and left little doubt of the gravity of the situation.

By midafternoon, the queen’s children and several of her grandchildren had converged on Balmoral, a sprawling 19th-century castle in the Scottish Highlands where the queen and her family have long spent their summers.

Charles and Camilla had been staying in a royal residence not far from Balmoral, and he was reportedly paying regular visits to his mother. Her daughter, Princess Anne, was also in Scotland already.

A Royal Air Force jet carried several other members of the royal family to the nearby city of Aberdeen, where they boarded a motorcade to Balmoral. That included her two other sons, Andrew and Edward, and Prince William, the eldest son of Charles, who is now the heir to the throne.

Prince Harry, who with his American-born wife, Meghan, had a bitter rupture with the royal family, made his way to Scotland on his own, arriving well after the queen’s death was announced. The couple saw the queen at Windsor Castle recently to introduce her to her newest great-granddaughter, Lilibet, who bears the childhood nickname that Elizabeth’s parents gave her.

The cause of the queen’s death was not known; the palace has said in the past that she has problems with mobility. She recovered from a bout with Covid-19 in February, which she later said had left her exhausted.

With no further updates after the midday statement that her doctors were “concerned,” there was a mounting sense of portent as the day unfolded. The BBC suspended its regular programming to carry continuous news coverage, its cameras trained on the iron gates of Balmoral, which swung open periodically as vehicles arrived or left. Heavy rain showers added to the gloom.

The vigil came after a week that offered a powerful reminder of the queen’s role in Britain’s constitutional monarchy. On Tuesday, she met Ms. Truss and her outgoing predecessor, Boris Johnson, both of the Conservative Party. In a photograph, a smiling, if fragile-looking, queen greeted Ms. Truss before a roaring fireplace, a walking stick in her left hand.

Mr. Johnson, who spoke to the queen on an almost weekly basis for his three years in office, issued an emotional statement upon her death.

“As is so natural with human beings, it is only when we face the reality of our loss that we truly understand what has gone,” Mr. Johnson said. “It is only really now that we grasp how much she meant for us, how much she did for us, how much she loved us.”

By tradition, the monarch invites a new prime minister to form a government after the outgoing one submits his or her resignation. This time, the ceremony, known as kissing hands, was moved from Buckingham Palace to Balmoral on the advice of her doctors to spare the queen the need to travel to London.

Beyond such formal rituals, the queen was a symbol of continuity and constancy over eight decades. She served as a living link to the glories of World War II Britain, presided over its fitful adjustment to a post-colonial, post-imperial era, and saw it through its bitter divorce from the European Union.

There is no analogous British figure who will be mourned as deeply — Winston Churchill might come closest — or whose death will provoke a greater reckoning with the identity and future of the country. Her extraordinary longevity lent her a sense of permanence that makes her death, even at an advanced age, somehow shocking.

Her steadfastness also helped the House of Windsor weather its own upheavals. Dignified and dutiful, she managed to rise above the tabloid headlines, whether about her troubled sister, Princess Margaret; Charles and his failed marriage to Diana; her second son, Andrew, who settled a sex abuse case linked to his ties with the disgraced financier Jeffrey Epstein; or the soap opera of Harry and Meghan.

One well-documented misstep came after Diana’s death, when the queen declined for days to leave Balmoral to join in the nation’s grieving. She finally expressed her sorrow in a televised address, speaking, she said, as a “grandmother.”

The queen’s declining health had been a recurring cause of concern for the past few years, forcing her to cancel many public appearances, even much-loved events like her annual commemoration of Britain’s wartime dead.

She had largely retreated to Windsor Castle, her country residence outside London, though this year she kept to her summer habit of decamping for Balmoral, where she enjoyed walking on the estate’s craggy hills and sylvan dales.

During the Platinum Jubilee in June, marking her 70 years on the throne, a smiling monarch appeared on the balcony of Buckingham Palace to watch a parade and a Royal Air Force flyover in her honor. But she skipped most of the rest of the celebrations, including a gala concert held in Queen Victoria Square, in front of the palace. She stopped traveling outside Britain several years ago.

As the queen receded from public view, Charles took on many of her public duties, including the state opening of Parliament and the conferring of knighthoods.

In April 2021, the queen lost her husband of 73 years, Prince Philip, who died a few weeks before his 100th birthday. At Philip’s memorial service, she sat, masked and alone, in a choir stall at St. George’s Chapel in Windsor Castle, a poignant symbol of the pandemic’s social distancing restrictions.

Even near the end, in her declining state, the queen was a constant, revered figure in the public life of her country. During the depths of the pandemic, she addressed a socially isolated nation, assuring Britons, in the words of Vera Lynn’s beloved World War II-era song, that “We will meet again.”
