During the time Queen Elizabeth II was on the throne there were a staggering 14 American Presidents - and Her Majesty met all of them apart from just one. The late Monarch was beloved by the American people, with many praising her for bringing warmth to the 'special relationship' between the UK and the US.
Having a state visit to see the Queen was the pinnacle of many President's time in the Oval Office - and she also made six official trips to America along with a number of private trips in pursuit of her loveof horse racing and thoroughbreds in Kentucky. Her Majesty was even gracious enough to overlook a number of blunders made by Presidents, and sometimes their First Ladies, who struggled to follow royal protocol.
