Constitutional monarchy, also known as limited monarchy, parliamentary monarchy or democratic monarchy, is a form of monarchy in which the monarch exercises their authority in accordance with a constitution and is not alone in making decisions. Constitutional monarchies differ from absolute monarchies in that they are bound to exercise powers and authorities within limits prescribed by an established legal framework.
The republics in the Commonwealth of Nations are the sovereign states in the organisation with a republican form of government. As of June 2022, 36 out of the 56 member states were republics. While Charles III is the titular Head of the Commonwealth, the King is not the head of state of the republican members. The King is however, the reigning monarch in the Commonwealth realms. The Head of the Commonwealth role does not carry with it any power; instead, it is a symbol of the free association of Commonwealth members.
The monarchy of Jamaica is a system of government in which a hereditary monarch is the sovereign and head of state of Jamaica. The current Jamaican monarch and head of state, since 8 September 2022, is King Charles III. As sovereign, he is the personal embodiment of the Jamaican Crown. 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 Jamaica and, in this capacity, he and other members of the royal family undertake public and private functions domestically and abroad as representatives of the Jamaican state. However, the monarch is the only member of the royal family with any constitutional role.

There are six monarchies in Oceania where supreme power resides with an individual hereditary head, who is recognised as the head of state. Each is a constitutional monarchy, wherein the sovereign inherits his or her office, usually keeps it until death or abdication, and is bound by laws and customs in the exercise of their powers. Five of these independent states share King Charles III as their respective head of state, making them part of a global grouping known as the Commonwealth realms; in addition, all monarchies of Oceania are members of the Commonwealth of Nations. The only sovereign monarchy in Oceania that does not share a monarch with another state is Tonga. Australia and New Zealand have dependencies within the region and outside it, although five non-sovereign constituent monarchs are recognized by New Zealand, Papua New Guinea and France.

Queen of Rhodesia was the title asserted for Elizabeth II as Rhodesia's constitutional head of state following the country's Unilateral Declaration of Independence from the United Kingdom. However, the position only existed under the Rhodesian constitution of 1965 and remained unrecognised elsewhere in the world. The British government, along with the United Nations and almost all governments, regarded the declaration of independence as an illegal act and nowhere else was the existence of the British monarch having separate status in Rhodesia accepted. With Rhodesia becoming a republic in 1970, the status or existence of the office ceased to be contestable.
