A look back at King Charles III's visits to US

Prince Charles has been preparing for the crown his entire life. Now, at age 73, that moment has finally arrived. Charles, the oldest person to ever assume the British throne, became King Charles III on Thursday following the death of his mother, Queen Elizabeth II. No date has been set for his coronation.

After an apprenticeship that began as a child, Charles embodies the modernization of the British monarchy. He was the first heir not educated at home, the first to earn a university degree and the first to grow up in the ever-intensifying glare of the media as deference to royalty faded. As the United Kingdom mourns a beloved queen, the nation is already wondering how King Charles III will reign and whether his monarchy will depart from the traditions of his mother.

If his first full day on the throne is any indication, Charles seemed ready to chart at least a slightly different course. When Charles traveled to Buckingham Palace for the first time as the new king Friday, his limousine snaked through a sea of spectators then stopped short of the palace gates before he got out and shook hands with well-wishers. Charles looked more like a U.S. president on the campaign trail than the latest steward of a 1,000-year-old hereditary monarchy.
