Commonwealth realm

Source From Wikipedia English.

A Commonwealth realm is a sovereign state within the Commonwealth that has Charles III as its monarch and ceremonial head of state. All the realms are equal with and independent of the others, though one person, resident in the United Kingdom, acts as monarch of each. The phrase Commonwealth realm is an informal description not used in any law.

  Former realms and dominions that are now republics

As of 2024, 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. While the Commonwealth of Nations has 56 independent member states, only these 15 have Charles III as head of state. He is also Head of the Commonwealth, a non-constitutional role.

The notion of these states sharing the same person as their monarch traces back to 1867 when Canada became the first dominion, a self-governing nation of the British Empire; others, such as Australia (1901) and New Zealand (1907), followed suit. With the growing independence of the dominions in the 1920s, the Balfour Declaration of 1926 established the Commonwealth of Nations and that the nations were considered "equal in status ... though united by a common allegiance to the Crown". The Statute of Westminster 1931 further set the relationship between the realms and the Crown, including a convention that any alteration to the line of succession in any one country must be voluntarily approved by all the others. The modern Commonwealth of Nations was then formally constituted by the London Declaration in 1949, when India wanted to become a republic without leaving the Commonwealth; this left seven independent nations sharing the Crown: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon (now Sri Lanka). Since then, new realms have been created through the independence of former colonies and dependencies; Saint Kitts and Nevis is the youngest extant realm, becoming one in 1983. Some realms became republics; Barbados changed from being a realm to a republic in 2021.

Current realms

There are currently 15 Commonwealth realms scattered across three continents (nine in North America, five in Oceania, and one in Europe), with a combined area of 18.7 million km2 (7.2 million sq mi) (excluding the Antarctic claims which would raise the figure to 26.8 million km2 (10.3 million sq mi)) and a population of more than 150 million.

Relationship between the realms

Charles III, the reigning sovereign of each of the Commonwealth realms since 2022

The Commonwealth realms are sovereign states. They are united only in their voluntary connection with the institution of the monarchy, the succession, and the King himself; the person of the sovereign and the Crown were said in 1936 to be "the most important and vital link" between the dominions. Political scientist Peter Boyce called this grouping of countries associated in this manner "an achievement without parallel in the history of international relations or constitutional law." Terms such as personal union, a form of personal union, and shared monarchy, among others, have all been advanced as definitions since the beginning of the Commonwealth itself, though there has been no agreement on which term is most accurate.

Under the Balfour Declaration of 1926, dominions were proclaimed to be "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 the monarch is the leader "equally, officially, and explicitly of separate, autonomous realms". Andrew Michie wrote in 1952 that "Elizabeth II embodies in her own person many monarchies: she is Queen of Great Britain, but she is equally Queen of Canada, Australia, New Zealand, Pakistan, South Africa, and Ceylon ... It is now possible for Elizabeth II to be, in practice as well as theory, equally Queen in all her realms." Still, Boyce holds the contrary opinion that the crowns of all the non-British realms are "derivative, if not subordinate" to the crown of the United Kingdom.

Since each realm has the same person as its monarch, the diplomatic practice of exchanging ambassadors with letters of credence and recall from one head of state to another does not apply. Diplomatic relations between the Commonwealth realms are thus at a cabinet level only, and high commissioners are exchanged between realms (though all other countries in the Commonwealth of Nations also follow this same practice, for traditional reasons). A high commissioner's full title will thus be High Commissioner Extraordinary and Plenipotentiary for His Majesty's Government in [Country].[citation needed] For certain ceremonies, the order of precedence for the realms' high commissioners or national flags is set according to the chronological order of, first, when the country became a dominion and then the date on which the country gained independence.[failed verification]

Conflicts of interest have arisen from this relationship amongst independent states. Some have been minor diplomatic matters, such as the monarch expressing on the advice of one of his/her cabinets views that counter those of another of his/her cabinets. More serious issues have arisen with respect to armed conflict, where the monarch, as head of state of two different realms, may be simultaneously at war and at peace with a third country, or even at war with themself as head of two hostile nations.

The Crown in the Commonwealth realms

The evolution of dominions into realms has resulted in the Crown having both a shared and a separate character, with the one individual being equally monarch of each state and acting as such in right of a particular realm as a distinct legal person guided only by the advice of the cabinet of that jurisdiction. This means that in different contexts, the term Crown may refer to the extra-national institution associating all 15 countries, or to the Crown in each realm considered separately. In Australia, it has been suggested that the Crown is further divided, with it possible that the monarchy in each of the states is a separate institution, equal in status to each other. The monarchy is therefore no longer an exclusively British institution.

From a cultural standpoint, the sovereign's name, image and other royal symbols unique to each nation are visible in the emblems and insignia of governmental institutions and militia. Elizabeth II's effigy, for example, appears on coins and banknotes in some countries, and an oath of allegiance to the King is usually required from politicians, judges, military members and new citizens. By 1959, it was being asserted by Buckingham Palace officials that the Queen was "equally at home in all her realms".

Robert Hazell and Bob Morris argued in 2017 that there are five aspects to the monarchy of the Commonwealth realms: the constitutional monarchy, including the royal prerogative and the use thereof on the advice of local ministers or according to convention or statute law; the national monarchy, comprising the functions of the head of state beyond the purely constitutional; the international monarchy, where the monarch is head of state in the 15 realms and holds the position of head of the Commonwealth; the religious monarchy, meaning the sovereign as head of the Church of England and his relationship with the Presbyterian Church of Scotland; and the welfare/service monarchy, wherein the sovereign and other members of the royal family give their patronage to charities and other elements of civil society.

Royal succession and regency

To guarantee the continuity of multiple states sharing the same person as monarch, the preamble of the Statute of Westminster 1931 laid out a convention that any alteration to the line of succession in any one country must be voluntarily approved by the parliaments of all the realms. This convention was first applied in 1936 when the British government conferred with the dominion governments during the Edward VIII abdication crisis. Prime Minister of Canada William Lyon Mackenzie King pointed out that the Statute of Westminster required Canada's request and consent to any legislation passed by the British parliament before it could become part of Canada's laws and affect the line of succession in Canada. Sir Maurice Gwyer, first parliamentary counsel in the UK, reflected this position, stating that the Act of Settlement was a part of the law in each dominion. Though today the Statute of Westminster is law only in Canada, Australia and the United Kingdom, the convention of approval from the other realms was reasserted by the Perth Agreement of 2011, in which all 16 realms at the time agreed in principle to change the succession rule to absolute primogeniture, to remove the restriction on the monarch being married to a Catholic, and to reduce the number of members of the Royal Family who need the monarch's permission to marry. These changes came into effect on 26 March 2015. Alternatively, a Commonwealth realm may choose to cease being such by making its throne the inheritance of a different royal house or by becoming a republic, actions to which, though they alter the country's royal succession, the convention does not apply.

Agreement among the realms does not, however, mean the succession laws cannot diverge. During the abdication crisis in 1936, the United Kingdom passed His Majesty's Declaration of Abdication Act with the approval of the parliament of Australia and the governments of the remaining dominions. (Canada, New Zealand and South Africa gave parliamentary assent later.) The act effected Edward's abdication in the United Kingdom on 11 December; as the Canadian government had requested and consented to the act becoming part of Canadian law, and Australia and New Zealand had then not yet adopted the Statute of Westminster, the abdication took place in those countries on the same day. The parliament of South Africa, however, passed its own legislation—His Majesty King Edward the Eighth's Abdication Act, 1937—which backdated the abdication there to 10 December. The Irish Free State recognised the king's abdication with the Executive Authority (External Relations) Act 1936 on 12 December. According to Anne Twomey, this demonstrated "the divisibility of the Crown in the personal, as well as the political, sense". For E. H. Coghill, writing as early as 1937, it proved that the convention of a common line of succession "is not of imperative force" and Kenneth John Scott asserted in 1962 that it ended the "convention that statutory uniformity on these subjects would be maintained in the parts of the Commonwealth that continued to owe allegiance to the Crown".

Today, some realms govern succession by their own domestic laws, while others, either by written clauses in their constitution or by convention, stipulate that whoever is monarch of the United Kingdom is automatically also monarch of that realm. It is generally agreed that any unilateral alteration of succession by the UK would not have effect in all the realms.

Following the accession of George VI to the throne, the United Kingdom created legislation that provided for a regency if the monarch was not of age or incapacitated. During debate that law, Sir John Simon opined that each Dominion would have to decide if it needed to legislate with respect to a regency; though, such legislation would not be required until the occasion arose. This was because the governors-general could still perform viceregal functions during a regency in Britain, including giving royal assent to any Dominion law giving effect to a regency in that Dominion. In the United Kingdom, on the other hand, legislation was needed in advance because, otherwise, there would be no one to give assent to a regency law if the sovereign were incapacitated. Though input was sought from the Dominions on the matter, all declined to make themselves bound by the British legislation, agreeing with Simon. Tuvalu later incorporated this principle into its constitution. New Zealand included in its Constitution Act 1986 a clause specifying that, should a regent be installed in the United Kingdom, that individual would carry out the functions of the monarch of New Zealand.

Monarch's role in the realms

King George VI, with Queen Elizabeth, grants royal assent to bills in the Senate of Canada, May 1939

The sovereign resides in the oldest realm, the United Kingdom. The king appoints viceroys to perform most of the constitutional and ceremonial duties on his behalf in the other realms: in each, a governor-general as his personal national representative, as well as a lieutenant governor as his representative in each of the Canadian provinces and governor as his representative in each of the Australian states. These appointments are made on the advice of the prime minister of the country or the premier of the province or state concerned, though this process may have additional requirements. The extent to which specific additional powers are reserved exclusively for the monarch varies from realm to realm. On occasions of national importance, the King may be advised to perform in person his constitutional duties, such as granting royal assent or issuing a royal proclamation. Otherwise, all royal powers, including the royal prerogative, are carried out on behalf of the sovereign by the relevant viceroy. In the United Kingdom, the king appoints Counsellors of State to perform his constitutional duties in his absence.

Similarly, the monarch will perform ceremonial duties in the Commonwealth realms to mark historically significant events. Citizens in Commonwealth realms may request birthday or wedding anniversary messages to be sent from the sovereign. This is available for 100th, 105th and beyond for birthdays; and 60th ("Diamond"), 65th, 70th ("Platinum") and beyond for wedding anniversaries.

Religious role of the monarch

It is solely in England that the King plays a role in organised religion where he acts as the Supreme Governor of the Church of England and nominally appoints its bishops and archbishops. In Scotland, he swears an oath to uphold and protect the Church of Scotland and sends a Lord High Commissioner as his representative to meetings of the church's General Assembly, when he is not personally in attendance.


Delegates at the Colonial Conference of 1902

Until the early part of the 20th century, the monarch's title throughout the British Empire was determined exclusively by the Parliament of the United Kingdom. As the dominions gained importance, the British government began to consult their governments on how the monarch should be titled. Ahead of the coronation of King Edward VII in 1902, the British Secretary of State for the Colonies, Joseph Chamberlain, suggested the King have the title King of Great Britain and Ireland and of Greater Britain Beyond the Seas. Canadian officials, however, preferred explicitly mention of the dominions: King of Great Britain and Ireland, Emperor of India, King of Canada, Australasia, South Africa and all the British Dominions Beyond the Seas, or, more simply, King of all the British Dominions Beyond the Seas. The King favoured the latter suggestion, which was adopted as [Edward VII] of the United Kingdom of Great Britain and Ireland and of the British Dominions beyond the Seas King.

By 1926, following the issuance of the Balfour Declaration, it was determined that the changes in the nature of the Empire needed to be reflected in King George V's title (something the King felt to be a "bore"). This led to the Royal and Parliamentary Titles Act 1927; though, again, this applied one title to the King across the whole Empire. The preamble to the Statute of Westminster 1931 established the convention requiring the consent of all the dominions' parliaments, as well as that of the United Kingdom, to any alterations to the monarch's style and title. This first came into play when the Royal and Parliamentary Titles Act was amended in 1948, by domestic law in Britain and each of the dominions, to remove George VI's title Emperor of India. Within the year, however, discussions about rewording the monarch's title began again when Ireland repealed legislation conferring functions on the king. The governments of Pakistan and Canada this time wanted more substantial changes, leading South Africa and Ceylon to also, along with Pakistan, request the elimination of the terms grace of God and defender of the faith; by the will of the people was suggested as a replacement. All that was agreed at the Commonwealth Prime Ministers' Conference in 1949 was that each of George VI's countries should have a different title, but with common elements, and it would be sufficient for each realm's parliament to pass a local law.

Queen Elizabeth II with the Commonwealth prime ministers during their conference in December 1952

The matter went unresolved until Elizabeth II became queen in 1952, upon which the realms issued their respective accession proclamations using different titles for their monarch. Debate ensued thereafter. The Australian government preferred that the monarch's title name all of the realms, but said it would accept Elizabeth II (by the Grace of God) of the United Kingdom of Great Britain and Northern Ireland, [name of realm], and all of her other Realms and Territories Queen, Head of the Commonwealth (Defender of the Faith). The South African government objected, stating that did not express the equality of status among the realms. Canadian officials wanted the word queen to precede the name of the realm so as to form the term Queen of Canada, which they felt expressed Elizabeth's distinct role as Canada's sovereign. There was even discussion about the placement of a comma following the Queen's name and regnal number, with the Secretary of State for Commonwealth Relations advising the use of punctuation was appropriate, as the term by the grace of God had been used in conjunction with the title king or queen since the reign of William II in the 11th century, whereas it had no such association with the position of head of the Commonwealth; so, Elizabeth II was queen by the grace of God, but her position as head of the Commonwealth was a secular arrangement.

In the end, it was decided the common wording in the titles was to be Queen of her other Realms and Territories, Head of the Commonwealth. Regardless, Ceylon and South Africa used Queen of [Ceylon/South Africa] and her other Realms and Territories, omitting by the grace of God and defender of the faith, while Australia, Canada, and New Zealand opted for of the United Kingdom, [Australia/Canada/New Zealand] and her other Realms and Territories Queen, keeping by the grace of God and defender of the faith. Pakistan's Royal Style and Titles Act simply titled the Queen as Queen of the United Kingdom and of Her other Realms and Territories, Head of the Commonwealth.

After Ghana gained independence and became a Commonwealth realm in 1957, its parliament passed the Royal Style and Titles Act 1957, which followed the example of Ceylon and South Africa by giving Elizabeth the title Elizabeth the Second, Queen of Ghana and of Her other Realms and Territories, Head of the Commonwealth. Each new realm thereafter did the same. In 1973 Australia removed reference to the United Kingdom, followed by New Zealand the next year. By the time of Elizabeth's death in 2022, aside from the United Kingdom itself, only Canada retained mention of the United Kingdom in the monarch's title and only Canada and New Zealand retained a reference to the monarch as Defender of the Faith. The Canadian parliament, in 2023, passed legislation that removed those references, The bill received royal assent on 22 June 2023; a proclamation of the new title was issued on January 8, 2024.

Some members of the royal family have different heraldic standards for use in the appropriate realm.

Queen Elizabeth II employed various royal standards to mark her presence, the particular one used depending on which realm she was in or acting on behalf of at the time. All are heraldic banners incorporating the arms for that state and, save for those of the UK, were defaced in the centre with the device from the Queen's Personal Flag. The Queen would use that personal flag in realms where she did not have a royal standard. Many other members of the royal family have their own personal standards; however, only the Prince of Wales, Princess Royal, Duke of York and Duke of Edinburgh also have one each for Canada. Those without their own standard use a specific ermine-bordered banner of either the British, Scottish, or, when in or acting on behalf of Canada, Canadian royal arms.

The governors-general throughout the Commonwealth realms also each use a personal flag, which, like that of the sovereign, passes to each successive occupant of the office. Most feature a lion passant atop a St. Edward's royal crown with the name of the country across a scroll underneath, all on a blue background. The two exceptions are those of, since 1981, Canada (bearing on a blue background the crest of the Royal Coat of Arms of Canada) and, since 2008, New Zealand (a St. Edward's Crown above the shield of the Coat of arms of New Zealand). The lieutenant governors of the Canadian provinces each have their own personal standards, as do the governors of the Australian states.

Historical development

Dominions emerge

The possibility that a colony within the British Empire might become a new kingdom was first mooted in the 1860s, when it was proposed that the British North American territories of Nova Scotia, New Brunswick and the Province of Canada unite as a confederation that might be known as the Kingdom of Canada.

Although the dominions were capable of governing themselves internally, they remained formally—and substantively in regard to foreign policy and defence—subject to British authority, wherein the governor-general of each dominion represented the British monarch-in-Council reigning over these territories as a single imperial domain. It was held in some circles that the Crown was a monolithic element throughout all the monarch's territories; A.H. Lefroy wrote in 1918 that "the Crown is to be considered as one and indivisible throughout the Empire; and cannot be severed into as many kingships as there are dominions, and self-governing colonies".

This unitary model began to erode, however, when the dominions gained more international prominence as a result of their participation and sacrifice in the First World War. In 1919, Canadian prime minister Sir Robert Borden and South African minister of defence Jan Smuts demanded that, at the Versailles Conference, the dominions be given full recognition as "autonomous nations of an Imperial Commonwealth". As a result, although the King signed as High Contracting Party for the Empire as a whole, the dominions were also separate signatories to the Treaty of Versailles. They also became, together with India, founding members of the League of Nations. In 1921 the Prime Minister of the United Kingdom, David Lloyd George, stated that the "British dominions have now been accepted fully into the community of nations".

Interwar period

Balfour Declaration

The pace of independence increased in the 1920s, led by Canada, which exchanged envoys with the United States in 1920 and concluded the Halibut Treaty in its own right in 1923. In the Chanak crisis of 1922, the Canadian government insisted that its course of action would be determined by the Canadian parliament, not the British government, and, by 1925, the dominions felt confident enough to refuse to be bound by Britain's adherence to the Treaty of Locarno. The Viscount Haldane said in 1919 that in Australia the Crown "acts in self-governing States on the initiative and advice of its own ministers in these States".

King George V at the Imperial Conference of 1926

Another catalyst for change came in 1926, when Field Marshal the Lord Byng of Vimy, then Governor General of Canada, refused the advice of his prime minister (William Lyon Mackenzie King) in what came to be known colloquially as the King–Byng Affair. Mackenzie King, after resigning and then being reappointed as prime minister some months later, pushed at the Imperial Conference of 1926 for a reorganisation of the way the dominions related to the British government, resulting in the Balfour Declaration, which declared formally that the dominions were fully autonomous and equal in status to the United Kingdom. What this meant in practice was not at the time worked out; conflicting views existed, some in the United Kingdom not wishing to see a fracturing of the sacred unity of the Crown throughout the empire, and some in the dominions not wishing to see their jurisdiction have to take on the full brunt of diplomatic and military responsibilities.

An unofficial British Empire flag from the 1930s including the arms of the dominions

What did follow was that the dominion governments gained an equal status with the United Kingdom, a separate and direct relationship with the monarch, without the British Cabinet acting as an intermediary, and the governors-general now acted solely as a personal representative of the sovereign in right of that dominion. Though no formal mechanism for tendering advice to the monarch had yet been established—former Prime Minister of Australia Billy Hughes theorised that the dominion cabinets would provide informal direction and the British Cabinet would offer formal advice—the concepts were first put into legal practice with the passage in 1927 of the Royal and Parliamentary Titles Act, which implicitly recognised the Irish Free State as separate from the UK, and the King as king of each dominion uniquely, rather than as the British king in each dominion. At the same time, terminology in foreign relations was altered to demonstrate the independent status of the dominions, such as the dropping of the term "Britannic" from the King's style outside of the United Kingdom. Then, in 1930 George V's Australian ministers employed a practice adopted by resolution at that year's Imperial Conference, directly advising the King to appoint Sir Isaac Isaacs as the Australian governor-general. Calls were also made for the empire to adopt new symbols less centred on the United Kingdom specifically, such as a new British Empire flag that would recognize the elevated status of the dominions. Many unofficial designs were often displayed for patriotic celebrations such as coronations and Empire Day.

Statute of Westminster

These new developments were explicitly codified in 1931 with the passage of the Statute of Westminster, through which Canada, the Union of South Africa, and the Irish Free State all immediately obtained formal legislative independence from the UK, while in the other dominions adoption of the statute was subject to ratification by the dominion's parliament. Australia and New Zealand did so in 1942 and 1947, respectively, with the former's ratification back-dated to 1939, while Newfoundland never ratified the bill and reverted to direct British rule in 1934. As a result, the parliament at Westminster was unable to legislate for any dominion unless requested to do so, although the Judicial Committee of the Privy Council was left available as the last court of appeal for some dominions. Specific attention was given in the statute's preamble to royal succession, outlining that no changes to that line could be made by the parliament of the United Kingdom or that of any dominion without the assent of all the other parliaments of the UK and dominions, an arrangement a justice of the Ontario Superior Court in 2003 likened to "a treaty among the Commonwealth countries to share the monarchy under the existing rules and not to change the rules without the agreement of all signatories".

Edward VIII and Wallis Simpson in 1936. His proposal to marry her led to his abdication, an act that required the consent of the dominions.

This was all met with only minor trepidation, either before or at the time, and the government of the Irish Free State was confident that the relationship of these independent countries under the Crown would function as a personal union, akin to that which had earlier existed between the United Kingdom and Hanover (1801 to 1837), or between England and Scotland (1603 to 1707). Its first test came, though, with the abdication of King Edward VIII in 1936, for which it was necessary to gain the consent of the governments of all the dominions and the request and consent of the Canadian government, as well as separate legislation in South Africa and the Irish Free State, before the resignation could take place across the Commonwealth. At the height of the crisis, press in South Africa fretted about the Crown being the only thing holding the empire together and the bond would be weakened if Edward VIII continued "weakening kingship". Afterward, however, Francis Floud, Britain's high commissioner to Canada, opined that the whole affair had strengthened the connections between the various nations; though, he felt the Crown could not suffer another shock. As the various legislative steps taken by the dominions resulted in Edward abdicating on different dates in different countries, this demonstrated the division of the Crown post-Statute of Westminster.

The civil division of the Court of Appeal of England and Wales later found in 1982 that the British parliament could have legislated for a dominion simply by including in any new law a clause claiming the dominion cabinet had requested and approved of the act, whether that was true or not. Further, the British parliament was not obliged to fulfil a dominion's request for legislative change. Regardless, in 1935 the British parliament refused to consider the result of the Western Australian secession referendum of 1933 without the approval of the Australian federal government or parliament. In 1937, the Appeal Division of the Supreme Court of South Africa ruled unanimously that a repeal of the Statute of Westminster in the United Kingdom would have no effect in South Africa, stating: "We cannot take this argument seriously. Freedom once conferred cannot be revoked." Others in Canada upheld the same position.

Fully sovereign dominions

At the 1932 British Empire Economic Conference, delegates from the United Kingdom, led by Stanley Baldwin (then Lord President of the Council), hoped to establish a system of free trade within the British Commonwealth, to promote unity within the British Empire and to assure Britain's position as a world power. The idea was controversial, as it pitted proponents of imperial trade with those who sought a general policy of trade liberalisation with all nations. The dominions, particularly Canada, were also adamantly against dispensing with their import tariffs, which "dispelled any romantic notions of a 'United Empire'." The meeting, however, did produce a five-year trade agreement based upon a policy, first conceived in the 1900s, of Imperial Preference: the countries retained their import tariffs, but lowered these for other Commonwealth countries.

During his tenure as Governor General of Canada, Lord Tweedsmuir urged the organisation of a royal tour of the country by King George VI, so that he might not only appear in person before his people, but also personally perform constitutional duties and pay a state visit to the United States as king of Canada. While the idea was embraced in Canada as a way to "translate the Statute of Westminster into the actualities of a tour", throughout the planning of the trip that took place in 1939, the British authorities resisted at numerous points the idea that the King be attended by his Canadian ministers instead of his British ones. The Canadian prime minister (still Mackenzie King) was ultimately successful, however, in being the minister in attendance, and the King did in public throughout the trip ultimately act solely in his capacity as the Canadian monarch. The status of the Crown was bolstered by Canada's reception of George VI.

When the Second World War began, there was some uncertainty in the dominions about the ramifications of Britain's declaration of war against Nazi Germany. Australia and New Zealand had not yet adopted the Statute of Westminster; the Australian prime minister, Robert Menzies, considered the government bound by the British declaration of war, while New Zealand coordinated a declaration of war to be made simultaneously with Britain's. As late as 1937, some scholars were still of the mind that, when it came to declarations of war, if the King signed, he did so as king of the empire as a whole; at that time, William Paul McClure Kennedy wrote: "in the final test of sovereignty—that of war—Canada is not a sovereign state... and it remains as true in 1937 as it was in 1914 that when the Crown is at war, Canada is legally at war," and, one year later, Arthur Berriedale Keith argued that "issues of war or neutrality still are decided on the final authority of the British Cabinet." In 1939, however, Canada and South Africa made separate proclamations of war against Germany a few days after the UK's. Their example was followed more consistently by the other realms as further war was declared against Italy, Romania, Hungary, Finland and Japan. Ireland remained neutral, "shattering the illusion of imperial unity." At the war's end, it was said by F.R. Scott that "it is firmly established as a basic constitutional principle that, so far as relates to Canada, the King is regulated by Canadian law and must act only on the advice and responsibility of Canadian ministers."

The war had strained the alliance among the Commonwealth countries, which had been noted by the King. The Prime Minister of Australia, John Curtin, had stated in December 1941 "that Australia looks to America, free of any pangs about our traditional links of kinship with Britain." The Parliament of South Africa voted on 14 January 1942 on a motion proposing the country become a republic and leave the Commonwealth. British Prime Minister Winston Churchill was told "His Majesty is genuinely alarmed at the feeling, which appears to be growing in Australia and may well be aggravated by further reverses in the Far East. He very much hopes, therefore, that it may be possible to adopt as soon as possible some procedure which will succeed in arresting these dangerous developments without impairing the efficiency of the existing machinery."

Post-war evolution

Within three years following the end of the Second World War, India, Pakistan and Ceylon became independent dominions within the Commonwealth. India would soon move to a republican form of government. Unlike Ireland and Burma, however, there was no desire on the part of India to leave the Commonwealth, prompting a Commonwealth Conference and the London Declaration in April 1949, which entrenched the idea that republics be allowed in the Commonwealth so long as they recognised King George VI as Head of the Commonwealth and the "symbol of the free association of its independent member nations". Pakistan became a republic in 1956.

As these constitutional developments were taking place, the dominion and British governments became increasingly concerned with how to represent the more commonly accepted notion that there was no distinction between the sovereign's role in the United Kingdom and his or her position in any of the dominions. Thus, at the 1948 Prime Ministers' Conference the term dominion was avoided in favour of Commonwealth country, to avoid the subordination implied by the older designation.

Elizabeth II in 2010. In 2010, she addressed the United Nations as queen of 16 Commonwealth realms.

The Commonwealth's prime ministers discussed the matter of the new monarch's title, with St. Laurent stating at the 1953 Commonwealth Prime Ministers' Conference that it was important to agree on a format that would "emphasise the fact that the Queen is Queen of Canada, regardless of her sovereignty over other Commonwealth countries." The result was a new Royal Style and Titles Act being passed in each of the seven realms then existing (excluding Pakistan), which all identically gave formal recognition to the separateness and equality of the countries involved, and replaced the phrase "British Dominions Beyond the Seas" with "Her Other Realms and Territories", the latter using the word realm in place of dominion. Further, at her coronation, Elizabeth II's oath contained a provision requiring her to promise to govern according to the rules and customs of the realms, naming each one separately. The change in perspective was summed up by Patrick Gordon Walker's statement in the British House of Commons: "We in this country have to abandon... any sense of property in the Crown. The Queen, now, clearly, explicitly and according to title, belongs equally to all her realms and to the Commonwealth as a whole." In the same period, Walker also suggested to the British parliament that the Queen should annually spend an equal amount of time in each of her realms. Lord Altrincham, who in 1957 criticised Queen Elizabeth II for having a court that encompassed mostly Britain and not the Commonwealth as a whole, was in favour of the idea, but it did not attract wide support. Another thought raised was that viceregal appointments should become trans-Commonwealth; the governor-general of Australia would be someone from South Africa, the governor-general of Ceylon would come from New Zealand, and so on. The prime ministers of Canada and Australia, John Diefenbaker and Robert Menzies, respectively, were sympathetic to the concept, but, again, it was never put into practice.

On 6 July 2010, Elizabeth II addressed the United Nations in New York City as queen of 16 Commonwealth realms. The following year, Portia Simpson-Miller, the Prime Minister of Jamaica, spoke of a desire to make that country a republic, while Alex Salmond, the First Minister of Scotland and leader of the Scottish National Party (which favours Scottish independence), stated an independent Scotland "would still share a monarchy with ... the UK, just as ... 16 other [sic] Commonwealth countries do now." Dennis Canavan, leader of Yes Scotland, disagreed and said a separate, post-independence referendum should be held on the matter.

Following the Perth Agreement of 2011, the Commonwealth realms, in accordance with convention, together engaged in a process of amending the common line of succession according to each country's constitution, to ensure the order would continue to be identical in every realm. In legislative debates in the United Kingdom, the term Commonwealth realm was employed, but, it remained unused in any law.

In addition to the states listed above, the Dominion of Newfoundland was a dominion when the Statute of Westminster 1931 was given royal assent but effectively lost that status in 1934, without ever having assented to the Statute of Westminster, and before the term Commonwealth realm ever came into use. Due to a domestic financial and political crisis, the Newfoundland legislature petitioned the UK to suspend dominion status, the UK parliament passed the Newfoundland Act 1933, and direct rule was implemented in 1934. Rather than reclaiming dominion status after the Second World War, it became a province of Canada in 1949.

Republican referendums

A plebiscite held in 1937 saw the dominion of the Irish Free State adopt a republican constitution. However, Ireland, its new name, continued to be considered by the Commonwealth to be a member until Ireland terminated the statutory role of the king in 1949.

Subsequently six Commonwealth realms and dominions have held referendums to consider whether they should become republics. As of January 2020, of the eight referendums held, three have been successful: in Ghana, in South Africa and the second referendum in Gambia. Referendums that rejected the proposal were held in Australia, twice in Tuvalu, and in Saint Vincent and the Grenadines. Interest in holding a second referendum was expressed in Australia in 2010.

During the 2020 Jamaican general election, the People's National Party promised to hold a referendum on becoming a republic within 18 months if it won the election and polls suggested that 55 per cent of Jamaicans desired the country become a republic. However, the ruling Jamaica Labour Party, which had in 2016 promised a referendum but not carried one out, was re-elected.

Barbados, which had been a Commonwealth realm for 55 years since it gained independence in 1966, became a republic by vote of Parliament in October 2021, effective on 30 November 2021. Some Barbadians criticised the government's decision not to hold a referendum on the issue as being undemocratic.

In 2022, following the death of Elizabeth II and the accession of Charles III, the governments of Jamaica, The Bahamas, and Antigua and Barbuda announced their intentions to hold referendums.
