The Queen has played a pivotal role in the UK’s relationship with America over the decades.
Elizabeth II has met every US president of her reign so far – except for one.
Donald Trump’s state visit, which begins on Monday, is the third by an American president to the UK, following George W Bush’s in 2003 and Barack Obama’s in 2011.
Here’s a look at the Queen’s encounters with US leaders over the years:
Harry S Truman
In 1951, a young Princess Elizabeth – unknowingly three months away from becoming Queen – went to Washington and saw President Harry S Truman, who was still in the Oval Office when she acceded to the throne.
During her first state visit to America in 1957, now Queen, she met Dwight D Eisenhower.
They met again in Canada in 1959 and travelled on the Royal Yacht Britannia together.
John F Kennedy
The glamorous JFK and his wife Jackie dined with the Queen and the Duke of Edinburgh at Buckingham Palace in June 1961.
Lyndon B Johnson
Mr Johnson, then vice president, took over after Mr Kennedy’s assassination in 1963.
He was president until 1969 – but the Queen never met him, and he died in 1973.
Richard Nixon
Richard Nixon dined with the Queen at Buckingham Palace in February 1969.
In 1976, during the US bicentennial, the Queen met Gerald Ford in the US, and they danced together at the state dinner in the White House.
In 1977, the monarch was pictured in a billowing, wide-sleeved yellow gown alongside Jimmy Carter, in a black tie and tuxedo, when he came to London.
Ronald and Nancy Reagan stayed at the Queen’s favourite home, Windsor Castle, in 1982.
The monarch and the former film star shared a bond through their love of horses and rode side by side in Windsor Great Park.
George Bush Snr
George Bush Snr had lunch with the Queen at Buckingham Palace in 1989.
Bill Clinton
Bill Clinton and his wife Hillary met the Queen several times, including in December 2000 when, along with daughter Chelsea, they visited Buckingham Palace.
George W Bush visited the head of state at the palace in July 2001.
Two years later, in November 2003, Mr Bush paid an official state visit – the first by a US leader – and the Queen gave him a wide smile as they shook hands at her London residence.
He was honoured with a state banquet in the palace ballroom.
Parry claimed he was given the chance to get close enough to the Queen to have poisoned her, and he took pictures of the monarch’s plastic breakfast containers, and the bed in which US President Bush and his wife Laura were to sleep.
The visit was also met with large protests over the Iraq War.
When the Queen encountered Mr Bush again, in Washington DC in 2007, the president winked at her after making a gaffe.
Turning to the Queen and winking, he joked to his audience: “She gave me a look that only a mother could give a child.”
Mr Bush – in 2008 – was also received by the Queen at Windsor Castle.
Barack Obama
The Queen’s relationship with Barack Obama was a warm and friendly one.
The Queen and First Lady Michelle Obama acted like old friends when they put their arms around each other at the end of the event.
We were just “two tired ladies oppressed by our shoes”, she added.
A successful state visit to the UK followed in 2011 and the Obamas forged a strong bond with the Queen and her wider family – particularly Prince Harry, now the Duke of Sussex, and the Duke and Duchess of Cambridge.
The Duke of Edinburgh, then 94, drove the couple the short distance to Windsor Castle after their Marine One presidential helicopter touched down on the manicured lawns of the royal residence.
Donald Trump
Mr Trump was accorded a guard of honour and had tea with the Queen at Windsor Castle in July 2018.
As the Queen and the president walked across the lawn of the quadrangle to view the troops, the monarch appeared to gesture and point several times for him to move closer to the front line of soldiers.
He later said of the sovereign in an interview: “That is a beautiful woman.”
The billionaire-turned-politician’s controversial state visit from June 3 to June 5 includes a ceremonial welcome at Buckingham Palace, lunch with the Queen and the Duke of Sussex, tea with the Prince of Wales and the Duchess of Cornwall at Clarence House, and a grand state banquet in the palace ballroom.
