Commonwealth realmA Commonwealth realm is a sovereign state that has Charles III as its monarch and head of state. Charles succeeded his mother, Elizabeth II, as monarch of the Commonwealth realms immediately upon her death on 8 September 2022. All the realms are equal with and independent of the others, though one person, resident in the United Kingdom, acts as monarch of each. there are 15 Commonwealth realms: Antigua and Barbuda, Australia, The Bahamas, Belize, Canada, Grenada, Jamaica, New Zealand, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands, Tuvalu, and the United Kingdom.
British Overseas TerritoriesThe British Overseas Territories (BOTs), also known as the United Kingdom Overseas Territories (UKOTs), are fourteen territories with a constitutional and historical link with the United Kingdom, but do not form part of the United Kingdom itself. The permanently inhabited territories are internally self-governing, with the United Kingdom retaining responsibility for defence and foreign relations. All of the territories are inhabited by civilians, except three which are chiefly or only inhabited by military or scientific personnel.
DominionA Dominion was any of several self-governing nations of the British Empire. With the evolution of the British Empire into the Commonwealth of Nations, the dominions became independent states. "Dominion status" was first accorded to Canada, Australia, New Zealand, Newfoundland, South Africa, and the Irish Free State at the 1926 Imperial Conference through the Balfour Declaration of 1926, recognising Great Britain and the Dominions as "autonomous within the British Empire, equal in status, in no way subordinate one to another in any aspect of their domestic or external affairs, though united by a common allegiance to the Crown and freely associated as members of the British Commonwealth of Nations".
