A medieval romance is a dramatic verse or prose narrative that usually involves adventurous heroes, idealized love, exotic places, and supernatural events. This genre first appeared in France during the 12th century and soon spread to England. Many of the best-known romances celebrate the legendary King Arthur and his knights, who often risk their lives for the love of a noble lady or to uphold the code of behaviour known as chivalry. Sir Gawain and the Green Knight is considered one of the finest Arthurian romances.
