Hereditary monarchies In a
hereditary monarchy, the position of monarch is inherited according to a statutory or customary
order of succession, usually within one
royal family tracing its origin through a historical
dynasty or bloodline. This usually means that the heir to the throne is known well in advance of becoming monarch to ensure a smooth succession.
Primogeniture, in which the eldest child of the monarch is first in line to become monarch, is the most common system in hereditary monarchy. The order of succession is usually affected by rules on gender. Historically "agnatic primogeniture" or "patrilineal primogeniture" was favoured, that is inheritance according to seniority of birth among the sons of a monarch or
head of family, with sons and their male issue inheriting before brothers and their male issue, to the total exclusion of females and descendants through females from succession. This complete exclusion of females from dynastic succession is commonly referred to as application of the
Salic law. Another variation on agnatic primogeniture was the so-called semi-Salic law, or "agnatic-cognatic primogeniture", which allowed women to succeed only at the extinction of all the male descendants in the male line of the particular legislator. Before primogeniture was enshrined in European law and tradition, kings would often secure the succession by having their successor (usually their eldest son) crowned during their own lifetime, so for a time there would be two kings in
coregency—a senior king and a junior king. Examples were
Henry the Young King of England and the early
Direct Capetians in France. Sometimes, however, primogeniture can operate through the female line. , an elected founder of the hereditary
monarchy of Belgium In 1980,
Sweden became the first monarchy to declare equal (full cognatic) primogeniture, meaning that the eldest child of the monarch, whether female or male, ascends to the throne. Other kingdoms (such as the
Netherlands in 1983,
Norway in 1990,
Belgium in 1991,
Denmark in 2009, and
Luxembourg in 2011) have since followed suit. The
United Kingdom adopted absolute (equal) primogeniture (subject to the claims of existing heirs) on April 25, 2013, following
agreement by the prime ministers of the sixteen Commonwealth Realms at the 22nd Commonwealth Heads of Government Meeting. Other hereditary systems of succession included
tanistry, which is semi-elective and gives weight to merit and
Agnatic seniority. In some monarchies, such as
Saudi Arabia, succession to the throne first passes to the monarch's next eldest brother, and only after that to the monarch's children (agnatic seniority). On June 21, 2017, King Salman of Saudi Arabia revolted against this style of monarchy and elected his son to inherit the throne.
Elective monarchies , Sovereign of the
Vatican City State from 2013 to 2025 In an
elective monarchy, monarchs are
elected or appointed by somebody (an
electoral college) for life or a defined period, but then reign like any other monarch. There is no popular vote involved in elective monarchies, as the elective body usually consists of a small number of eligible people. Historical examples of elective monarchy are the
Holy Roman Emperors (chosen by
prince-electors but often coming from the same dynasty) and the
free election of kings of the
Polish–Lithuanian Commonwealth. For example,
Pepin the Short (father of
Charlemagne) was elected
King of the Franks by an assembly of Frankish leading men; nobleman
Stanisław August Poniatowski of Poland was an elected king, as was
Frederick I of Denmark.
Gallic and
Germanic peoples also had elective monarchies. The
Pope of the
Roman Catholic Church (who rules as
Sovereign of the
Vatican City State) is
elected for life by the
College of Cardinals. In the
Sovereign Military Order of Malta, the
Prince and Grand Master is elected for life tenure by the Council Complete of State from within its members. In
Malaysia, the federal king, called the
Yang di-Pertuan Agong or Paramount Ruler, is elected for a five-year term from among and by the hereditary rulers (mostly
sultans) of nine of the federation's constitutive
states, all on the
Malay peninsula. The
United Arab Emirates also chooses its federal leaders from among emirs of the federated states. Furthermore,
Andorra has a unique constitutional arrangement as one of its heads of state is the President of the
French Republic in the form of a
Co-Prince. In New Zealand, the Maori King, head of the Kingitanga Movement, is elected by a council of Maori elders at the funeral of their predecessor, which is also where their coronation takes place. All of the Heads of the Maori King Movement have been descendants of the first Maori King, Potatau Te Wherowhero, who was elected and became King in June 1858.
Usurpation Another way monarchs have historically gained royal power is by seizing it, either by force or other illegitimate measures. Historically usurpation has usually happened via a
coup or by fraudulently claiming be a descendant of a ruler that they may or may not be related to. According to
Herodotus, this was done by someone impersonating
Smerdis in order to seize the throne of
Cyrus the Great after his death.
Other ways of succession By accession The legitimacy and authorities of monarchs are often
proclaimed and recognized through occupying and being
invested with
insignia, seats,
deeds and
titles, like in the course of
coronations. This is especially employed to legitimize and settle disputed successions, changes in ways of succession, status of a monarch (e.g. as in the case of the
privilegium maius deed) or new monarchies altogether (e.g. as in the case of the
coronation of Napoleon I).
Succession crisis In cases of succession challenges, it can be instrumental for
pretenders to secure or install
legitimacy through the above, for example proof of accession like insignia, through treaties or a claim of a divine mandate to rule (e.g. by
Hong Xiuquan and his
Taiping Heavenly Kingdom). == Current monarchies ==
