A monarch is a head of state for life or until abdication, and therefore the head of state of a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Usually a monarch either personally inherits the lawful right to exercise the state's sovereign rights or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may proclaim oneself monarch, which may be backed and legitimated through acclamation, right of conquest or a combination of means.
A prince is a male ruler or a male member of a monarch's or former monarch's family. Prince is also a title of nobility, often hereditary, in some European states. The female equivalent is a princess. The English word derives, via the French word prince, from the Latin noun prīnceps, from primus (first) and caput (head), meaning "the first, foremost, the chief, most distinguished, noble ruler, prince".
Primogeniture is the right, by law or custom, of the firstborn legitimate child to inherit the parent's entire or main estate in preference to shared inheritance among all or some children, any illegitimate child or any collateral relative. In most contexts, it means the inheritance of the firstborn son ; it can also mean by the firstborn daughter, or firstborn child.
An heir apparent is a person who is first in an order of succession and cannot be displaced from inheriting by the birth of another person. A person who is first in the current order of succession but could be displaced by the birth of a more eligible heir is known as heir presumptive.
An heir presumptive is the person entitled to inherit a throne, peerage, or other hereditary honour, but whose position can be displaced by the birth of a person with a better claim to the position in question. This is in contrast to an heir apparent, whose claim on the position cannot be displaced in this manner.
An elective monarchy is a monarchy ruled by a monarch who is elected, in contrast to a hereditary monarchy in which the office is automatically passed down as a family inheritance. The manner of election, the nature of candidate qualifications, and the electors vary from case to case. Historically, it was common for elective monarchies to transform into hereditary ones by repeated election of the previous rulers' children, or for hereditary monarchies to acquire elective or semi-elective succession laws, particularly following dynastic crises.
The emperor of Austria was the ruler of the Austrian Empire and later the Austro-Hungarian Empire. The hereditary imperial title and office was proclaimed in 1804 by Francis II, Holy Roman Emperor, a member of the House of Habsburg-Lorraine, and continually held by him and his heirs until Charles I relinquished power in 1918.
Royal Highness is a style used to address or refer to some members of royal families, usually princes or princesses. Kings and their female consorts, as well as queens regnant, are usually styled Majesty.
A queen regnant is a female monarch, equivalent in rank, title and position to a king. She reigns suo jure over a realm known as a kingdom; as opposed to a queen consort, who is married to a reigning king; or a queen regent, who is the guardian of a child monarch and rules pro tempore in the child's stead or instead of her husband who is absent from the realm, be it de jure in sharing power or de facto in ruling alone. A queen regnant is sometimes called a woman king. A princess,duchess, or grand duchess regnant is a female monarch who reigns suo jure over a principality or (grand) duchy; an empress regnant is a female monarch who reigns suo jure over an empire.
Infante, also anglicised as "infant" or translated as "prince", is the title and rank given in the Iberian kingdoms of Spain and Portugal to the sons and daughters (infantas) of the king, regardless of age, sometimes with the exception of the heir apparent or heir presumptive to the throne who usually bears a unique princely or ducal title. A woman married to a male infante was accorded the title of infanta if the marriage was dynastically approved, although since 1987 this is no longer automatically the case in Spain. Husbands of born infantas did not obtain the title of infante through marriage, although they were occasionally elevated to the title de gracia at the sovereign's command.
The Danish royal family is the dynastic family of the monarch of Denmark. While some members of the Danish royal family hold the title of Prince(ss) of Denmark, descendants of Margrethe II additionally bear the title Count(ess) of Monpezat. Children of the monarch are accorded the style of His/Her Royal Highness. The King and Queen are styled Majesty.
Prince Imperial is the title created after the proclamation of independence of the Empire of Brazil, in 1822, to designate the heir apparent or the heir presumptive to the Brazilian imperial throne. Even after the proclamation of the Republic in 1889, the title was kept in use by the Brazilian Imperial Family.
An order, line or right of succession is the line of individuals necessitated to hold a high office when it becomes vacated, such as head of state or an honour such as a title of nobility. This sequence may be regulated through descent or by statute.
The Orléanist claimant to the throne of France is Jean, Count of Paris. He is the uncontested heir to the Orléanist position of "King of the French" held by Louis-Philippe, and is also considered the Legitimist heir as "King of France" by those who view the 1713 Treaty of Utrecht as valid. According to the Family Compact of 1909, only the descendants of Henri, Count of Paris are considered to be French dynasts. The founders of the cadet branches of Orleans-Braganza and Orléans-Galliera, by becoming foreigners, are considered under house law to have lost their rights to the throne.
The House of Hohenberg is an Austrian and Czech noble family that descends from Countess Sophie Chotek (1868–1914), who in 1900 married Archduke Francis Ferdinand of Austria-Este (1863–1914), the heir presumptive to the throne of the Austro-Hungarian Empire. As their marriage was a morganatic one, none of their children were in the line of succession to the Austro-Hungarian throne. Nevertheless, they represent the senior agnatic line of the House of Habsburg-Lorraine.
The monarchy of Denmark is a constitutional institution and a historic office of the Kingdom of Denmark. The Kingdom includes Denmark proper and the autonomous territories of the Faroe Islands and Greenland. The Kingdom of Denmark was already consolidated in the 8th century, whose rulers are consistently referred to in Frankish sources as "kings". Under the rule of King Gudfred in 804 the Kingdom may have included all the major provinces of medieval Denmark.
The Pauline Laws are the house laws of the Romanov rulers of the Russian Empire. The name comes from the fact that they were initially established by Emperor Paul I of Russia in 1797. Previously drafted privately as a contract between Paul Petrovich while being the heir apparent, and his wife Maria Feodorovna, it was made public and signed into law after Paul succeeded his mother Catherine II in November 1796 and was crowned Emperor.
The Crown Prince of Thailand is a title held by the heir apparent to the Thai throne. It was created by King Chulalongkorn in 1886, for his son Prince Maha Vajirunhis, the king's eldest son by a royal wife Queen Savang Vadhana. Prior to this, the Siamese throne did not have a law or formal system regulating royal succession. In 1688, King Phetracha of Ayutthaya created the title of Front Palace, which by the Rattanakosin period had become the main title granted to the heir presumptive to the throne. However, few Front Palaces succeeded to the throne this way, with the exception of King Phutthaloetla Naphalai in 1809. After the death of Bowon Wichaichan in 1885, the title of Front Palace was abolished and replaced with the title of Crown Prince, who became heir apparent to the throne.
Succession to the French throne covers the mechanism by which the French crown passed from the establishment of the Frankish Kingdom in 486 to the fall of the Second French Empire in 1870.
