Long before King Charles III was set to take the throne, he was known asPrince Charles.

Even as a child, sometimes that meant meeting other world leaders, including U.S. presidents.

Of the 14 presidents in office since Charles was born in 1948, he has met 10 of them.

The current monarch’s good favor among American leaders has spanned many decades.

Also in attendance were Prince Philip and Princess Anne.

By the time Eisenhower first took office in 1953, he and the queen were already well acquainted.

Eisenhower left office two years later in 1961 and died 10 years later in 1969.

The year was 1970, and 21-year-old Charles famously made the acquaintance of Tricia Nixon.

The 39th U.S. president had traveled to England to attend a NATO conference and was staying at Buckingham Palace.

At the event, President Reagan and King Charles both made toasts at the beginning of the evening.

As President Reagan wrote himself: “The dinner for the Prince and Diana was a great success.

It’s a small world, indeed.

After the former president died in 2018, Charles attended his funeral in place of his mother.

The queen was 92 years old at the time of Bush’s death.

The visit occurred amid the Afghanistan War, and Bush was met by protestors upon his arrival in London.

The pair sat across from one another in the Oval Office and spoke about many relevant issues.

Charles was amused by the joke but politely disagreed in response.

This trip marked Charles' 19th visit to the United States.

It is said that Trump did not get permission from Charles to publish the private letter.

A passionate environmentalist, Charles agreed to meet with Trump for tea on June 3, 2019.

However, it’s unclear how much Biden and Charles communicated with one another during this visit.

The next time Charles and Biden met was in Glasgow, Scotland in 2021.
