Queen Elizabeth marks 70 years on throne with Platinum Jubilee: Memorable moments from her reign
The 96-year-old queen is the first British monarch to reach a Platinum Jubilee -- 70 years on the throne.
LONDON -- Queen Elizabeth is being celebrated with what is being described as a once-in-a-lifetime celebration to mark her Platinum Jubilee.
The royal family and the public are taking part in festivities ranging from the traditional Trooping the Colour birthday parade to a star-studded concert to celebrate the 96-year-old queen, the first British monarch to reach a Platinum Jubilee -- 70 years on the throne.
Queen Elizabeth ascended to the throne following the death of her father, King George VI, on Feb. 6, 1952.

With celebrations underway, here is a look back at seven of the queen's most memorable moments from 70 years on the throne.
1. A history-making coronation
Queen Elizabeth's coronation on June 2, 1953, was the first to be televised.
The nearly three-hour service in Westminster Abbey was watched on TV by 27 million people in the United Kingdom alone, according to the royal family.
Queen Elizabeth and Prince Philip's oldest child, Prince Charles, attended the coronation, becoming the first child to witness his mother's coronation.
Following the service, the queen and Prince Philip joined a 16,000-person strong procession from Westminster Abbey to Buckingham Palace.
Among the thousands of journalists covering the queen's coronation was Jacqueline Bouvier, who at the time worked for the Washington Times-Herald and would go on to become first lady of the United States alongside her husband, President John F. Kennedy, according to the royal family.
2. The first royal 'walkabout' to greet fans
While royal watchers are used to seeing royals including Prince William and Duchess Kate greet fans at each stop they make, a practice called the "walkabout," that was not the case before Queen Elizabeth.
The queen upended royal tradition while on a tour of Australia and New Zealand with Prince Philip in 1970. Instead of waving to crowds from a protected distance, Queen Elizabeth walked out and greeted people in-person, the first royal "walkabout."
3. Meeting 13 sitting U.S. presidents
Queen Elizabeth has met with every U.S. president during her 70 years on the throne, except for Lyndon B. Johnson.
She met with President Joe Biden last June at Windsor Castle, marking her 13th meeting with a sitting U.S. president.
Queen Elizabeth has hosted just three presidents for an official state visit -- Presidents George W. Bush, Barack Obama and Donald Trump.
4. Celebrating jubilees in a history-making reign as queen
In 1977, Queen Elizabeth celebrated her Silver Jubilee, 25 years on the throne, with a service at St. Paul's Cathedral, where she repeated her pledge to a life of service.
More than two decades later, in 2002, -- the same year both her mother and sister passed away -- Queen Elizabeth celebrated 50 years on the throne, her Golden Jubilee.
The queen was escorted through the streets of London in a four-ton golden coach, previously used only when she was crowned and at her Silver Jubilee. In a ceremony that dates back almost 800 years, she touched a sword handed to her by the Lord Mayor of London, symbolizing the supreme power of the monarch.
In June 2012, Queen Elizabeth celebrated 60 years on the throne, her Diamond Jubilee, with a parade down the Thames and a concert outside Buckingham Palace.
Three years later, in 2015, Queen Elizabeth made history, becoming Britain's longest-reigning monarch, at 63 years.
5. 'Parachuting' into the London Olympics with James Bond
The same year as her Diamond Jubilee, in 2012, Queen Elizabeth memorably starred alongside actor Daniel Craig in a clip that aired during the opening ceremony for the 2012 Summer Olympics in London.
The queen portrayed herself in the clip, which featured Craig, as James Bond, picking her up at Buckingham Palace. Stunt actors then portrayed the two helicoptering across London and parachuting into the Olympics venue, while Queen Elizabeth herself arrived at her seat, accompanied by Prince Philip.
6. Serving as matriarch of a growing royal family
Queen Elizabeth has been an omnipresent force not just on the world stage, but also within her own family.
The queen, a mother of four, is the matriarch of an ever-growing family, which now includes eight grandchildren and 12 great-grandchildren.
She has been present for weddings, as well as divorces that made headlines.
She has also guided her family through scandal and discord, most recently amid a lawsuit against her son Prince Andrew, as well as the exit of her grandson Prince Harry and his wife, Duchess Meghan, from their senior royal roles.
7. Saying goodbye to her husband of 73 years
Queen Elizabeth faced a deeply personal and sad moment in her reign last April when she said goodbye to her husband, Prince Philip, following his death at age 99.
Due to restrictions amid the coronavirus pandemic, the queen sat alone during the April 17, 2021, funeral service for Philip, her husband of 73 years.
Known as one of the hardest-working members of the royal family, Philip, the Duke of Edinburgh, was also a stalwart supporter of his wife.
"He is someone who doesn't take easily to compliments, but he has, quite simply, been my strength and stay all these years," Queen Elizabeth said in 1997, paying tribute to her husband on their golden wedding anniversary. "And I, and his whole family, and this and many other countries, owe him a debt greater than he would ever claim, or we shall ever know."
