A bicorne, or bicorn, is a type of hat donned by military personnel in the late eighteenth century and early nineteenth century.
The hat, though not popularized by Napoleon I, is now widely identified with the famous French emperor. Almost all paintings of Napoleon at battle display him donning the hat; most characterizations of the historical figure today also associate Napoleon with his famous bicorne.
