High Quality Content by WIKIPEDIA articles! In the 1790s, the threat of invasion of the Kingdom of Great Britain was high, after the French Revolution and the rise of Napoleon Bonaparte. In order to improve the country's defences, volunteer regiments were raised in many counties from yeomen. The word "yeoman" refers to small farmers who owned the land they cultivated as opposed to peasants, but the officers were drawn from the nobility and many of the men were their tenants. These regiments became known collectively as the Yeomanry. Members of the yeomanry were not obliged to serve overseas without their individual consent.
