The British Yeomanry refers to a historical military force composed of volunteer cavalry units in the United Kingdom. Established in the late 18th century, these units were primarily made up of local gentlemen and farmers who provided their own horses and equipment. The Yeomanry played a significant role in various conflicts, including the Napoleonic Wars and the First World War. Originally formed for local defense and law enforcement, the Yeomanry evolved over time, becoming part of the Territorial Army in the early 20th century. Today, many Yeomanry units have transitioned into modern roles, serving as part of the Army Reserve and contributing to community engagement and military training.
