A bicorn is a type of hat characterized by its two peaks or points. It was popular in the late 18th and early 19th centuries, especially among military officers and members of the aristocracy. The design often features a wide brim and is typically made from materials like felt or silk. The bicorn is most famously associated with the Napoleonic Wars, as it was worn by Napoleon Bonaparte and his generals. This distinctive hat symbolizes the military fashion of the era and is often depicted in paintings and historical reenactments, representing a significant aspect of European history.
