Tuvalu / King Charles III

The monarchy of Tuvalu (the Tuvaluan monarchy) is a system of government in which a hereditary monarch (shared with a number of other countries of the Commonwealth) is the sovereign and head of state of Tuvalu. The King's constitutional roles are mostly delegated to the Governor-General of Tuvalu.

Royal succession is governed by the English Act of Settlement of 1701, which is part of constitutional law.

King Charles III acceded to the throne on 9 September 2022 upon the death of his mother, Queen Elizabeth II.

In Tuvalu King Charles III is styled: "His Majesty Charles the Third, by the Grace of God, King of Tuvalu and of His other Realms and Territories, Head of the Commonwealth" (thus omitting the "Defender of the Faith" title used in the United Kingdom and some other realms).

The Tuvaluan monarch, besides reigning in Tuvalu, separately serves as monarch for a number of other Commonwealth countries known as Commonwealth realms. This developed from the former colonial relationship of these countries to Great Britain, but they are now independent of each other and are legally distinct.
