The Atholl Highlanders is a private army formed in 1839 by the Duke of Atholl in Scotland. It is unique as it is the only private army in the United Kingdom, consisting of around 100 volunteer soldiers. The regiment primarily serves ceremonial purposes, participating in events such as parades and Highland games. The Atholl Highlanders wear traditional Scottish uniforms, including kilts and sporrans, reflecting their heritage. They are based at Blair Castle, the ancestral home of the Duke, where they also conduct training and community events. The regiment plays a significant role in preserving Scottish culture and traditions.
