The "French crown" refers to the royal headgear traditionally worn by the monarchs of France. It symbolizes the authority and sovereignty of the king or queen. The most famous crown is the Crown of Charlemagne, which was used during the coronation of French kings. Crowns in France often featured intricate designs, precious stones, and gold. They were not only ceremonial objects but also represented the divine right of kings, a belief that monarchs were chosen by God to rule. The use of crowns diminished after the French Revolution in the late 18th century, which led to the establishment of a republic.
