Royal Horse Guards

The Royal Horse Guards was a Household Cavalry regiment of the British Army. Originally founded in 1650 by Oliver Cromwell as the Regiment of Cuirassiers, the regiment later became the Earl of Oxford's Regiment during the reign of King Charles II. As the regiment's uniform was blue in colour at the time, it was nicknamed "the Oxford Blues"; hence the Royal Horse Guards was also nicknamed the "Blues." The RHG was amalgamated with the Royal Dragoons (1st Dragoons) to form the Blues and Royals (Royal Horse Guards and 1st Dragoons) in 1969.

There was also a titular regiment, the Horse Guards, which actually consisted of several independent troops: see Horse Guards Regiment. The Governor General's Horse Guards are the Household Cavalry in Canada, and part of the Commonwealth of Nations Household Division.
