Montjoie is a historical term that refers to a battle cry used during the Middle Ages, particularly by the French. It is often associated with the Crusades and was shouted by soldiers to invoke divine support and rally their comrades. The term is derived from the Latin phrase "Montis Jovis," meaning "Mount of Jupiter," symbolizing a call to arms and courage. In addition to its use as a battle cry, Montjoie is also linked to the legendary figure of Roland, a knight in the service of Charlemagne. The term appears in various medieval texts, including the famous epic poem, The Song of Roland, where it signifies loyalty and bravery in the face of adversity.
