The crown is divided into three categories, as follows:
Crown crown, the crown used to crown the ceremony, only worn when the monarch is crowned, may be worn by the church or worn by the church bishop.
The crown of the emperor, the crown worn by the monarch, represents the supreme power. * Aristocrats sometimes wear similar crowns to represent their identity.
After the crown, the crown worn by the Queen does not have the meaning of power, but only represents its noble status.
In some ancient countries, the crown may be worn on the head of the civilian rather than on the head of the monarch. For example, the generals who returned to Rome in the triumph of the ancients, the winners of the ancient Greek Olympics, etc., and the crowns are mostly made of laurel leaves.
