"King Charles revives Trooping the Colour tradition after 30 years hiatus"

King Charles will ride on horseback during the annual Trooping the Colour parade, marking the first time a reigning monarch has done so since his mother, Queen Elizabeth II, in 1986. Trooping the Colour is the annual birthday parade for the British sovereign, and over 1,400 soldiers, 400 horses, and 400 musicians take part. The king has attended the event since he was a child, first for his grandfather, King George VI, followed by his mother. The parade has its origins on the battlefield, where a regiment's flag or "colours" was a key rallying point for soldiers during battle.
