The Carabiniers (6th Dragoon Guards) was a cavalry regiment of the British Army. The regiment was descended from the Ninth Horse regiment, raised in response to the Duke of Monmouth's rebellion in 1685, the first year of the reign of King James II. Colonelcy of the Ninth Horse was given to Richard, 2nd Viscount Lumley of Waterford. In accordance with tradition of the time, the regiment became known as Lord Lumley's Horse. Shortly thereafter, Lumley petitioned the Queen Dowager to permit labeling the regiment The Queen Dowager's Horse, which request was granted. In 1691, during King William's Irish Campaign, the regiment distinguished itself, as a result of which it was posted to London and renamed The King's Carabiniers.
