The Yeomanry Cavalry was the mounted component of the British Volunteer Corps, a military auxiliary established in the late 18th century amid fears of invasion and insurrection during the French Revolutionary Wars. A yeoman was a person of respectable standing, one social rank below a gentleman, and the yeomanry was initially a rural, county-based force. Members were required to provide their own horses and were recruited mainly from landholders and tenant farmers, though the middle class also featured prominently in the rank and file. Officers were largely recruited from among the nobility and landed gentry. A commission generally involved significant personal expense, and although social status was an important qualification, the primary factor was personal wealth. From the beginning, the newly rich, who found in the yeomanry a means of enhancing their social standing, were welcomed into the officer corps for their ability to support the force financially. Urban recruitment increased towards the end of the 19th century, reflected in the early 20th century by increasingly common use of hired mounts.
