The Paladins, also called the Twelve Peers, are twelve legendary knights, the foremost members of Charlemagne's court in the 8th century. They first appear in the medieval chanson de geste cycle of the Matter of France, where they play a similar role to the Knights of the Round Table in Arthurian romance. In these romantic portrayals, the chivalric paladins represent Christianity against a Saracen (Muslim) invasion of Europe. The names of the paladins vary between sources, but there are always twelve of them led by Roland. The paladins' most influential appearance is in The Song of Roland, written between 1050 and 1115, which narrates the heroic death of Roland at the Battle of Roncevaux Pass.
