 The Blues (also known as The Royal Horse Guards) was one of two regiments which formed The Household Cavalry. The other regiment in The Household Cavalry was The Life Guards. Alongside regular army duties, they formed a personal bodyguard to the monarch.

In 1969, The Blues joined The Royal Dragoons to form The Blues and Royals, which still serves in conjunction with The Life Guards in The Household Cavalry.
