The Queen's Own Royal Glasgow Yeomanry was a yeomanry regiment of the British Army that can trace their formation back to the late 18th century, when King George III was on the throne, William Pitt the Younger was the Prime Minister of the United Kingdom, and across the English Channel, Britain was faced by a French nation that had recently guillotined its king and possessed a revolutionary army numbering half a million men. The prime minister proposed that the English Counties form a force of Volunteer Yeoman Cavalry that could be called on by the king to defend the country against invasion or by the Lord Lieutenant to subdue any civil disorder within the country.
