The month of June is the month of the Sacred Heart of Jesus and, as we have discussed before, this devotion has long been a very prominent one for Catholic monarchists. Here is a look at some of them:
French counterrevolutionaries wore the Sacred Heart as a badge, an item which was the closest thing they had to a uniform. As such, the Sacred Heart became very associated with the French royalists as a whole.
The Sacred Heart, portrayed in simple form, was featured on many flags and banners of the royalist forces as well as the badges they wore over their breasts. Because the symbol became so associated with French monarchism it is still featured today on many royalist flags and insignia.
In Spain, the devout Catholics of the Carlist faction made the Sacred Heart a prominent symbol in their own movement. Some wore the Sacred Heart as a badge on their uniforms (as seen above) while others scratched the symbol on to their weapons or in more modern times even painted the symbol on their vehicles. Carlist banners also often featured the Sacred Heart incorporated in the Spanish royal arms.
In Mexico the Catholic rebels known as the Cristeros often featured the Sacred Heart on their flags. They were what we might call "spiritual monarchists" (their battlecry was 'Long live Christ the King') and had they been more successful, who knows, they might have become more political monarchists. Their top general did see himself as another Miguel Miramon, one of the generals shot alongside Emperor Maximilian.
