A hussar was a member of a class of light cavalry, originating in Central Europe (Hungary) during the 15th and 16th centuries. The title and distinctive dress of these horsemen were subsequently widely adopted by light cavalry regiments in European armies during the late 17th and 18th centuries. By the 19th century, hussars were wearing jackets decorated with braid plus shako or busby fur hats and had developed a romanticized image of being dashing and adventurous.

A shako is a tall, cylindrical military cap, usually with a visor, and sometimes tapered at the top. It is usually adorned with an ornamental plate or badge on the front, metallic or otherwise; and often has a feather, hackle, or pompom attached at the top.
