A Sikh soldier became the first to wear a turban instead of a bearskin hat during the annual parade that celebrates the Queen's Birthday.
Guardsman Charanpreet Singh Lall, 22, marched among 1,000 soldiers taking part in Trooping the Colour ceremony.
His turban was black to match his comrades' headgear and featured the Coldstream Guards' ceremonial cap star.
His proud parents and sister were among the crowds lining Horse Guards Parade for the ceremony.
Lall, from Leicester, who came to the UK from India as a boy, said: "Being the first turban-wearing Sikh to troop the colour and be part of the escort is a high honour."
"I hope people will look on this as a change in history," Lall, who joined up in 2016, added.
"I hope that more people like me, not just Sikhs, but people from other religions and backgrounds, will be encouraged to join the Army," he was quoted as saying by Express newspaper.
While Queen Elizabeth celebrated her actual birthday on April 21, the Trooping of the Colour takes place on any Saturday of June.
