A crown is a traditional headwear worn by a monarch(King/Queen) or by a deity, for whom the crown traditionally represents power, legitimacy, victory, triumph, honor, and glory, as well as immortality, righteousness, and resurrection. In art, the crown may be shown being offered to those on Earth by angels. Apart from the traditional form, crowns also may be in the form of a wreath and be made of flowers, oak leaves, or thorns and be worn by others, representing what the coronation part aims to symbolize with the specific crown. In religious art, a crown of stars is used similarly to a halo. Crowns worn by rulers often contain jewels.
Three distinct categories of crowns exist in those monarchies that use crowns or state regalia.
A crown is often an emblem of the monarchy, a monarch's government, or items endorsed by it. The word itself is used, particularly in Commonwealth countries, as an abstract name for the monarchy itself, as distinct from the individual who inhabits it (see The Crown). A specific type of crown (or coronet for lower ranks of peerage) is employed in heraldry under strict rules. Indeed, some monarchies never had a physical crown, just a heraldic representation, as in the constitutional kingdom of Belgium, where no coronation ever took place; the royal installation is done by a solemn oath in parliament, wearing a military uniform: the King is not acknowledged as by divine right, but assumes the only hereditary public office in the service of the law; so he in turn will swear in all members of "his" federal government.
