King Charles participated today, Saturday, in his first military parade officially celebrating his birthday as monarch, where he rode a horse and inspected the soldiers during the annual event held since 1760. The military parade, known as "Trooping the Colour," comes weeks after Charles was crowned king of Britain on May 6. Soldiers in crimson coats and fur hats participated in the procession as military bands played music. Charles, 74, revived a tradition that his late mother, Queen Elizabeth, abandoned in 1986 when she was 60 years old. In the annual tribute to the king by the British army, soldiers saluted King Charles as he inspected them in front of a crowd of eight thousand people. His eldest son, Prince William, Princess Anne, and his brother, the Duke of Edinburgh, also rode horses, with the Queen and the Princess of Wales in a carriage behind them.
