Montjoie Saint Denis! was the battle-cry and motto of the Kingdom of France. It allegedly referred to Charlemagne’s legendary banner the Oriflamme, which was also known as the “Montjoie” and was kept at the Abbey of Saint Denis, though alternative explanations exist. The battle-cry was first used during the reign of Louis VI of France, the first royal bearer of the Oriflamme.
Sounds like someone that is proud of their past history to me.
Thanks.
