lançer

n. soldier on horseback armed with a lance

A lancer (uhlan) was a cavalry soldier who fought with a lance. Although cavalry had used lances for thousands of years, lancers in the modern European sense originated in Poland in the 18th century. Polish lancers serving with the French Army proved highly effective during the Napoleonic Wars, and by the end of the war all major European states had established lancer regiments of their own.
