Meghan Markle took a break from maternity leave to make an appearance at the annual Trooping the Colour parade in honor of Queen Elizabeth II’s birthday.

Prince Harry, Prince William and his wife Kate Middleton, Prince Charles and his wife Camilla were also in attendance for the celebration which took place on Saturday.

The Duke and Duchess of Sussex waved to the crowds in their carriage which was shared by the Duchess of Cambridge and Camilla.

The ceremony originated from traditional preparations for battle.

The colors — or flags — were "trooped," or carried down the lines of soldiers, so they could be seen and recognized in battle. The regimental flag being paraded this year is from the 1st Battalion Grenadier Guards.
