A coronation is a comprehensive liturgical and constitutional ceremony in which a monarch is physically and symbolically invested with the regalia of state, such as the crown, orb, and sceptre. In the English tradition, this rite is distinguished by its sacral nature, specifically the act of anointing with holy oil by the Archbishop of Canterbury, which historically signified the monarch's dual status as both sovereign and 'persona mixta'—an individual holding both temporal and spiritual jurisdictions. The ceremony serves as the public ratification of the succession, the fulfillment of the Coronation Oath, and the formal recognition of the sovereign by the estates of the realm.
From a heraldic and feudal perspective, the coronation is the paramount display of armorial achievement and feudal tenure. It involves various 'Grand Sergeanty' claims, where members of the nobility perform specific hereditary services—such as carrying the Great Spurs or the Sword of State—in exchange for their lands and titles. The Earl Marshal and the Garter King of Arms preside over the ceremonial protocols, ensuring that the hierarchy of the peerage is strictly observed in the procession. As both a religious consecration and a legal contract between the Crown and the people, it remains the oldest and most complex continuous state ritual in Europe.
