The East Riding of Yorkshire Yeomanry Cavalry was formed in 1902 although predecessor units form the East Riding were raised in the 18th century to meet the threat from Jacobite rebels and French revolutionary forces. It became part of the Territorial Force in 1908 and was expanded during World War One (1914-1918). The unit was converted from cavalry to armour in 1920.
