It was created as part of the reduction in the cavalry in the aftermath of World War I. It was formed by the amalgamation of the 15th The King`s Hussars and the 19th Royal Hussars (Queen Alexandra`s Own) on 11 April 1922, becoming the 15th/19th Hussars. It briefly dropped the 19th numeral from its title in 1932, becoming the 15th The King`s Royal Hussars, before regaining it the following year.
