A sabre is a type of backsword with a curved blade associated with the light cavalry of the early modern and Napoleonic periods. Originally associated with Central European cavalry such as the hussars, the sabre became widespread in Western Europe during the Thirty Years' War. Lighter sabres also became popular with infantry of the early 17th century. In the 19th century, models with less curving blades became common and were also used by heavy cavalry.

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.
