The monarchy of Antigua and Barbuda is a system of government in which a hereditary monarch is the sovereign and head of state of Antigua and Barbuda. The current Antiguan and Barbudan monarch and head of state since 8 September 2022, is King Charles III. As sovereign, he is the personal embodiment of the Crown of Antigua and Barbuda. Although the person of the sovereign is equally shared with 14 other independent countries within the Commonwealth of Nations, each country's monarchy is separate and legally distinct. As a result, the current monarch is officially titled King of Antigua and Barbuda and, in this capacity, he and other members of the Royal Family undertake public and private functions domestically and abroad as representatives of Antigua and Barbuda. However, the King is the only member of the Royal Family with any constitutional role. All executive authority is vested in the monarch, and royal assent is required for the Parliament of Antigua and Barbuda to enact laws and for letters patent and Orders in Council to have legal effect. Most of the powers are exercised by the elected members of parliament, the ministers of the Crown generally drawn from amongst them, and the judges and justices of the peace. Other powers vested in the monarch, such as the appointment of a prime minister, are significant but are treated only as reserve powers and as an important security part of the role of the monarchy. The Crown today primarily functions as a guarantor of continuous and stable governance and a nonpartisan safeguard against the abuse of power. While some powers are exercisable only by the sovereign, most of the monarch's operational and ceremonial duties are exercised by his representative, the governor-general of Antigua and Barbuda. Origin The island of Antigua was explored by Christopher Columbus in 1493, and became a colony of Britain in 1632; Barbuda island was first colonised in 1678. Having been part of the Federal Colony of the Leeward Islands from 1871, Antigua and Barbuda joined the West Indies Federation in 1958. With the breakup of the federation, it became one of the West Indies Associated States in 1967. Following self-governance in its internal affairs, independence was granted from the United Kingdom on 1 November 1981. Antigua and Barbuda became a sovereign state and an independent constitutional monarchy within the Commonwealth. Princess Margaret represented her sister, Queen Elizabeth II, at the
