The 6th Dragoon Guards raised in 1685 as the "Queen Dowager's Regiment of Horse" and became the "Queen Dowager's Cuirassiers."

William III gave the regiment its name of King's Carabiniers in 1691 as a title of honour in recognition of its distinguished services. The name is also derived from the fact that the men were armed with long pistols called "Carabines." Many regiments on the Continent at this time were called Carabiniers. Its present name was given it in 1788. It greatly distinguished itself during Marlborough's campaigns, taking part in sieges and minor affairs without number. It was at Meerut on the outbreak of the Indian Mutiny and rendered the most valuable service throughout the campaign. The regiment has a very brilliant record of service.

Nicknames: "Tichborne's Own," since the trial of Arthur Orton, Sir Roger Tichborne having served in the regiment; and "The Carbs."
