Non-executive heads of state


One form that the head of state role takes can be loosely called the non-executive head of state model. Its holders are excluded completely from the executive: they do not possess even theoretical executive powers or any role, even formal, within the government. Hence their states' governments are not referred to by the traditional parliamentary model head of state styles

In reality, numerous variants exist to the position of a head of state within a parliamentary system. The older the constitution, the more constitutional leeway tends to exist for a head of state to exercise greater powers over government, as many older parliamentary system constitutions in fact give heads of state powers and functions akin to presidential or semi-presidential systems, in some cases without containing reference to modern democratic principles of accountability to parliament or even to modern governmental offices.

 but any head of state – elected, hereditary, or dictatorial – who presides. It is sometimes called the "imperial model," without regard for the monarchic title emperor, rather referring to the luster.


Some constitutions or fundamental laws provide for a head of state who is not just in theory but in practice chief executive, operating separately from, and independent from, the legislature. This system is sometimes known as a "presidential system" because the government is answerable solely and exclusively to a presiding, acting head of state, and is selected by and on occasion dismissed by the head of state without reference to the legislature. It is notable that some presidential systems, while not providing for collective executive answerability to the legislature, may require legislative approval for individuals prior to their assumption of cabinet office and empower the legislature to remove a president from office (for example, in the United States of America
United States

The United States of America is a Federal government constitutional republic comprising U.S. state and a federal district.

). In this case the debate centres on the suitability of the individual for office, not a judgement on them when appointed, and does not involve the power to reject or approve proposed cabinet members en bloc, so it is not answerability in the sense understood in a parliamentary system.

Some presidential systems may also include a prime minister, but, as with the other ministers, they are responsible to the president, not the legislature. In many such instances the office is of minimal political importance, sometimes even held by some administrative technocrat rather than a politician. A prime minister in a presidential system lacks the constitutional and political dominance of a prime minister in a parliamentary system and is often seen as simply a politically junior figure who may run the mechanics of government while allowing the president to set the broad national agenda.

Semi-presidential systems combine features of presidential and parliamentary systems, notably a requirement that the government be answerable to both the president and the legislature.

Other countries evolve into something akin to a semi-presidential system or indeed a full presidential system. Weimar Germany, for example, in its constitution provided for a popularly elected president with theoretically dominant executive powers that were intended to be exercised only in emergencies, and a cabinet appointed by him from the Reichstag

The Reichstag was the parliament of the Holy Roman Empire, the North German Confederation, and of Germany until 1945. The main chamber of the German parliament is now called Bundestag , but the building in which it meets is still called "Reichstag" ....
, which was expected, in normal circumstances, to be answerable to the Reichstag. Initially, the President was merely a symbolic figure with the Reichstag dominant; however, persistent political instability, in which governments often lasted only a few months, led to a change in the power structure of the republic, with the president's emergency powers called increasingly into use to prop up governments challenged by critical or even hostile Reichstag votes. By 1932, power had shifted to such an extent that the German President, Paul von Hindenburg

s to dismiss any of his or her governments at will would suggest that any of the realms should nominally belong to the semi-presidential category also. In reality, the category to which each head of state belongs is assessed not by theory but by practice. In practice no Commonwealth realms monarch has forced a government from office since the early nineteenth century, while, in reality, the Greek republic, even before the powers of the President of the Republic were curtailed in 1986, operated as a standard parliamentary system. Unless and until a Prince of Liechtenstein exercises the theoretical powers that office now possesses, the principality would still remain categorised as a parliamentary system.

Roles of the head of state

Often depending on which constitutional category (above) a head of state belongs to, they may have some or all of the roles listed below, and various other ones.

Symbolic role

Canadacourt2
One of the most important roles of the modern head of state is being a living national symbol of the state; in monarchies this extends to the sovereign being a symbol of the unbroken continuity of the state. For instance, the Canadian monarch is described by the government as being the personification of the Canadian state

s of the head of state can be found in government offices, courts of law, even airports, libraries, and other public buildings. The idea, sometimes regulated by law, is to use these portraits to make the public aware of the symbolic connection to the government, a practice that dates back to mediaeval times. Sometimes this practice is taken to excess, and the head of state begins to believe that he is the only symbol of the nation, resulting in the emergence of a personality cult where the image of the head of state is the only visual representation of the country, surpassing other symbols such as the flag

. Other common iconic presences, especially of monarchs, are on coins, stamps, and banknotes; more discreet variations see them represented by a mention and/or signature. Furthermore, various institutions, monuments, and the like, are named for current or previous heads of state, such as streets and squares, schools, charitable and other organisations; in monarchies (e.g. Belgium) there can even be a practice to attribute the adjective 'royal' on demand based on existence for a given number of years. However, such political techniques can also be used by leaders without the formal rank of head of state, even party - and other revolutionary leaders without formal state mandate.

In general, the active duties amount to a ceremonial role. Thus in diplomatic affairs, heads of state are often the first person to greet an important foreign visitor. They may also assume a sort of informal host role during the VIP's visit, inviting the visitor to a state dinner

State dinners in different countries follow different rules and are governed by different Protocol ....
 at his or her mansion or palace, or some other equally hospitable affair.

At home, they are expected to render luster to various occasions by their presence, such as by attending artistic or sports performances or competitions, expositions, celebrations, military parades and remembrances, prominent funerals, visiting parts of the country, enterprises, care facilities (often in a theatrical honour box, on a platform, on the front row, at the honours table etc.), sometimes performing a symbolic act such as cutting a ribbon or pushing a button at an opening, christening something with champagne, laying the first stone, and so on. Some parts of national life receive their regular attention, often on an annual basis, or even in the form of official patronage.

As the potential for such invitations is enormous, such duties are often in part delegated: to such persons as a spouse, other members of the dynasty, a vice-president —for whom this is often the core of their public role— or in other cases (possibly as a message, for instance, to distance themselves without giving protocollary offence) just a military or other aide.

For non-executive heads of state there is often a degree of censorship by the politically responsible government (such as the prime minister), discreetly approving agenda and speeches, especially where the constitution (or customary law) assumes all political responsibility by granting the crown inviolability (in fact also imposing political emasculation) as in the Kingdom of Belgium from its very beginning; in a monarchy this may even be extended to some degree to other members of the dynasty, especially the heir to the throne.

However, there are provisions in international law to perform the same diplomatic functions, or at least part of them, such as accrediting, with a lower title with the head of government, or functioning within another mission.

The head of state also signs international treaties on behalf of the state, or has them signed in his/her name by ministers (government members or diplomats); subsequent ratification

In a constitutional monarchy or non-executive presidency the head of state may hold the ultimate authority over the armed forces but will only normally, as per either written or conventional laws, exercise their authority on the advice of their ministers, meaning de facto decision making on military manoeuvers lies with the cabinet. The monarch or president will, however, perform ceremonial duties related to the country's armed forces, and will sometimes appear in military uniform for these purposes; in the case of a female sovereign her consort and other members of the royal family may also appear in military garb. This is generally the only time a head of state of a stable, democratic country will appear dressed in such a manner, as statesmen and public are eager to assert the primate of (civilian, elected) politics over the armed forces.

Summoning and dissolving the legislature

A head of state is often empowered to summon and dissolve the country's legislature. In most parliamentary systems, this is done on the advice of the head of government (e.g. Prime Minister) or cabinet. In some parliamentary systems, and in some presidential systems, however, the head of state may do so on their own initiative. Some states have fixed term parliaments, with no option of bringing forward elections (e.g. Article II, Section 3, of the U.S. Constitution). In other systems there are usually fixed terms, but the head of state retains authority to dissolve the legislature in certain circumstances. Where a head of government has lost the confidence of parliament, some heads of state may refuse a parliamentary dissolution, where one is requested, forcing the head of government's resignation. Example: Article 13.2.2. of the Constitution of Ireland

Selection and various types and styles of Heads of State

Various heads of state use a multitude of different styles and titles, often with many variations in content under diverse constitutions, even in a given state. In numerous cases, two or more of the following peculiar types apply, not counting the primary duo monarchy-republic. There are also several methods of head of state succession

In a monarchy, the Monarch is the Head of State. This is a relatively recent phenomenon; until the last few decades a sovereign was seen as the personal embodiment of the state ("L'etat c'est moi", so to speak), and therefore could not be head of himself or herself (hence many constitutions from the 19th century and earlier make no mention of a "head of state"). Though some still maintain that calling a Monarch Head of State is incorrect, it has now become a widespread political convention to attach the label to Monarchs, regardless of their political position.

Whenever a head of state is not available for any reason, constitutional provisions may allow the role to fall temporarily to an assigned person or collective body.

In a monarchy, this is usually a regent

In Commonwealth realms the Governor-General may fulfill many of the roles of a head of state, but is typically not, either legally or conventionally, regarded as the head of state, but rather as an appointed representative of the head of state mandated to act in his or her place, even when the monarch is present in the country.

Legitimacy & Term in office

The position of head of state (within, or as well as, the state) can be established in different ways, and based on different legitimations.
  • Force is often the true origin of power, but to keep the victor’s right, formal legitimacy must be found, even if by fictitious claim of continuity such as forged descent or legacy from a previous dynasty
  • There have also been true cases of granting sovereignty, such as dynastic splits (not just by laws of succession, also by deliberate acts); this is usually forced, such as self-determination granted after nationalist revolts, or the last Attalid king of Hellenistic Pergamon
    Pergamon

    Pergamon or Pergamum was an ancient Ancient Greece city in modern-day Turkey, in Mysia, north-western Anatolia, 16 miles from the Aegean Sea, located on a promontory on the north side of the river Caicus , that became the capital of the Kingdom of Pergamon during the Hellenistic Greece, under the Attalid dynasty, 281–133 BC....

Individual heads of state may acquire their position in a number of constitutional ways:
  • The position of a Monarch is usually hereditary, but often with constitutional restrictions, or even considerable liberty for the incumbent or some body convening after his demise to chose from eligible members of the ruling house, often limited to legal descendants of the state religion or even parliamentary permission. There are rare exceptions to this, such as the Pope

      An acclamation, in its most common sense, is a form of election that does not use a ballot. "Acclamation" or "acclamatio" can also signify a kind of ritual greeting and expression of approval in certain social contexts in ancient Rome....
      ; the electorate can be very selective, such as the patrician families and/or the professional corporations of a city state, or by the warriors in the case of a 'tribal' type war chief or a Roman general proclaimed by his legions.

A head of state may however seize power by force or revolution. This is not to be confused with the notion of an authoritarian or other totalitarian ruler, which rather concerns the oppressive nature of power once acquired, and therefore applies only if he is the true chief executive. Dictators often use democratic titles, though some proclaim themselves monarchs. Examples of the latter include Emperor Napoleon III of France

Another type of extra-constitutional imposition, often also changing the constitution, is by a foreign power (state or alliance), either benign or, more often, rather for its own interest, such as establishing a branch of their own or a friendly dynasty.

Apart from violent ousting, a head of state's position can also be lost in several ways:
  • death (by natural causes, attentate, execution, on the battlefield or other), even in case of an unlawful killing
  • expiration of the term of office under various (nearly always republican and/or elective) constitutions
  • abdication, which is legally a voluntary act (though it can be the result of overpowering political or other pressure); in some cases, an abdication cannot occur unilaterally, but comes into effect only when approved by an act of parliament (e.g. King Edward VIII of the United Kingdom
    Edward VIII of the United Kingdom

    Edward VIII was Monarch of the United Kingdom of Great Britain and Northern Ireland and the dominion, and Emperor of India from 20 January 1936, following the death of his father, George V of the United Kingdom, until his abdication on 11 December 1936....
    )
  • abolition of the post by constitutional change of the institutions (occasionally on the contrary, a transitory clause provides the last incumbent may end his term) or even ending the existence of the state as such
  • while generally a head of state enjoys the widest form of inviolability, in some states the exceptions to this includes impeachment

  • serious violation of certain fundamental treaty obligations is sometimes considered a (disputable) valid reason for the relevant international community to depose a head of state, as the Security Council of the UN or certain alliances may do
  • formal declaration of incapacity to rule, usually on such medical grounds as insanity or coma; this may either result in suspension (see below) or termination of his mandate


All ways of ending a head of state's term may carry a risk for the next incumbent, usually by contesting the validity of the procedure, but sometimes even after death in the case of pretenders.

Some states dispute the international acceptance of the right of their deposed monarchs to be referred to by their former title. It remains however the generally accepted formula, with most states declining to get involved in disputes between governments and deposed monarchs and simply stating that they are doing no more than recognising tradition, not supporting claims to a defunct throne. Other states have no problem with deposed monarchs being so referred to by former title, and even allow them to travel internationally on the state's diplomatic passport.
