The Princess of Wales was praised for her subtle nod to Princess Diana that you may have missed at first glance.Why do we celebrate Trooping the Colour, anyway?Back in the 17th century, battlefield communication was absolute chaos. Amid the smoke, noise, and confusion of war, a regiment’s custom flag – its "Colour" – was used as a visual rallying point. If a soldier got lost, they looked for the flag. To ensure every single man recognised his unit's Colour, young officers would parade, or "troop," the flag slowly down the ranks before a battle.‌In 1748, King George II decided to combine this military tradition with his official birthday celebration. He was born in November, a month notorious for terrible British weather, so he simply moved his public birthday to June to ensure better conditions for a parade.That quirk stuck, and today, Trooping the Colour serves as the official, public birthday celebration for the reigning British Sovereign, currently King Charles III.Article continues belowToday, the parade is a staggering logistical feat carried out by the Household Division, the monarch's personal troops. The sheer scale of the operation is hard to overstate.It features more than 1,400 parading soldiers, 400 military musicians, and roughly 200 horses. However, the most iconic moment is watching the Red Arrows fly over London in celebration.Millions of people watch the event globally every year. It is a brilliant display of British pomp and pageantry, after all.
