The 14th/20th King’s Hussars was a British Army cavalry regiment of the line.
Originally styled the 14th/20th Hussars, the Regiment came into being in 1922 on the amalgamation of the 14th King’s Hussars with the 20th Hussars as part of the reductions in the Army after the First World War. The honorific King’s was added back into the title in 1936.
The 14th were originally raised as Dormer’s Dragoons in 1715 during the First Jacobite Rising. The regiment became light dragoons in 1776 and were designated as hussars in 1861. The 20th were raised as light dragoons in 1759 and became hussars in 1862.
The 14th/20th were amalgamated in 1992 with the The Royal Hussars (Prince of Wales's Own) to become The King's Royal Hussars.
