Crowns

Special headgear to designate rulers dates back to pre-history, and is found in many separate civilizations around the globe. Commonly, rare and precious materials are incorporated into the crown, but that is only essential for the notion of crown jewels. Gold and precious jewels are common in western and oriental crowns. In the Native American civilizations of the Pre-Columbian New World, rare feathers, such as that of the quetzal, often decorated crowns; so too in Polynesia (e.g. Hawaii).
• Coronation is often combined with other rituals, such as enthronement (the throne is as much a symbol of monarchy as the crown) and anointing (again religious sanction, the only defining act in the Biblical tradition of Israel).
In other cultures no crown is used in the equivalent of coronation, but the head may still be otherwise symbolically adorned, as a royal tikka in the Hindu tradition of India.
