A coronation ceremony marks the formal investiture of a monarch with regal power using a crown. In addition to the crowning, this ceremony may include the presentation of other items of regalia, and other rituals such as the taking of special vows by the new monarch, the investing and presentation of regalia to them, and acts of homage by the new monarch's subjects. In certain Christian denominations, such as Lutheranism and Anglicanism, coronation is a religious rite. As such, Western-style coronations have often included anointing the monarch with holy oil, or chrism as it is often called; the anointing ritual's religious significance follows examples found in the Bible. The monarch's consort may also be crowned, either simultaneously with the monarch or as a separate event.
Once a vital ritual, coronations have changed over time for a variety of socio-political and religious reasons; most modern monarchies have dispensed with them altogether, preferring simpler ceremonies to mark a monarch's accession. Coronations are still observed in the United Kingdom, Tonga, Thailand, Malaysia (federal and state), and Eswatini. The most recent coronation in the world was that of King Charles III and Queen Camilla in London in 2023. In Europe, most monarchs are required to take a simple oath in the presence of the country's legislature. Besides a coronation, a monarch's accession may be marked in many ways: some nations may retain a religious dimension to their accession rituals, while others have adopted simpler inauguration ceremonies, or even no ceremony at all. Some cultures use bathing or cleansing rites, the drinking of a sacred beverage, or other religious practices to achieve a comparable effect. Such acts symbolise the granting of divine favour to the monarch within the relevant spiritual-religious paradigm of the country.
