The Oriflamme (from Latin aurea flamma, "golden flame") was the battle standard of the King of France in the Middle Ages. It was originally the sacred banner of the Abbey of St. Denis, a monastery near Paris. When the oriflamme was raised in battle by the French royalty during the Middle Ages, most notably during the Hundred Years War, no prisoners were to be taken until it was lowered. Through this tactic they hoped to strike fear into the hearts of the enemy, especially the nobles, who could usually expect to be taken alive for ransom during such military encounters.
In French, the term "oriflamme" has come to mean any banner with pointed ends; by association with the form of the original.
The Oriflamme was mentioned in the eleventh-century ballad the Chanson de Roland (vv. 3093-5) as a royal banner, first called Romaine and then Montjoie. According to legend, Charlemagne carried it to the Holy Land in response to a prophecy regarding a knight possessing a golden lance, from which flames would burn and drive out the Saracens. This suggests that the lance was originally the important object, with the banner simply a decoration, but this changed over time.
The Oriflamme was first used by Louis VI in 1124 and was last flown in battle at Agincourt in 1415, though a version of it remained in the Abbey of St. Denis until the 18th century.
Louis VI replaced the earlier banner of Saint Martin with the oriflamme of the Abbey of St. Denis, which floated about the tomb of St. Denis and was said to have been given to the abbey by Dagobert. Until the 12th century the standard-bearer was the Comte de Vexin, who, as vowed to St. Denis, was the temporal defender of the abbey. Louis VI, having acquired Vexin, became standard-bearer; as soon as war began, Louis VI received Communion at St. Denis and took the standard from the tomb of the saint to carry it to the combat.
It is recorded as having been carried at the following battles/campaigns:
The Oriflamme was lost at least five times during its medieval history; Mons-en-Pévèle, Crécy Poitiers and Agincourt, and also during the campaigns of the Seventh Crusade under King Louis IX.
