Charles' participation in the parade on horseback marked thefirst time since 1986that the British monarch rode in the procession. Queen Elizabeth last rode during Trooping the Colour 37 years ago before opting to take part in the pageantry in a carriage in the years that followed.

Prince William took over the role of Colonel of the Welsh Guards from his father after King Charles became monarch. The position is a fit with William becoming the Prince of Wales, the traditional title for the British heir to the throne.

When the procession reached Horse Guards' Parade, Queen Camilla and Princess Kate hopped out of the carriage and joined the other royal colonels as the Welsh Guards presented their flag, or “colour,” to the King. It marked a royal first for the royal women — in past years, both Camilla and Kate would watch the ceremony from a building overlooking the parade grounds with other royals.

While King Charles' actual birth date is November 14, he will also be fêted each year with public festivities of his birthday in June as British monarch.
According to theHousehold Division, the tradition of the British monarch having both an actual birthday and official birthday dates back to the reign of the current sovereign’s namesake predecessor, King Charles II, who ruled from 1660 to 1685. In 1748, it was decided that this parade would be used to mark the official birthday of the monarch, and Trooping the Colour became an annual event during the reign of King George III.

The reason for the official festivities taking place in June is also quite practical, as the weather in the U.K. is better!
