reign
A reign is the period of a person's or dynasty's occupation of the office of monarch of a nation (e.g., King of Saudi Arabia, Saudi Arabia, List of Belgian monarchs, Belgium, Co-princes of Andorra, Andorra), of a people (e.g., List of Frankish kin ...
s and subsequently, historically. Since ancient times, some monarchs have chosen to use a different name from their original name when they accede to the monarchy.
The regnal name is usually followed by a
regnal number, written as a
Roman numeral
Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers are written with combinations of letters from the Latin alphabet, ea ...
, to differentiate that monarch from others who have used the same name while ruling the same realm. In some cases, the monarch has more than one regnal name, but the regnal number is based on only one of those names, for example
Charles X Gustav of Sweden. If a monarch reigns in more than one realm, they may carry different ordinals in each one, as some realms may have had different numbers of rulers of the same regnal name. For example, the same person was both
King James VI of Scotland and King James I of England.
The ordinal is not normally used for the first ruler of the name, but is used in historical references once the name is used again. Thus,
Queen Elizabeth I of England was called simply "Elizabeth of England" until the accession of
Queen Elizabeth II almost four centuries later in 1952; subsequent historical references to the earlier queen retroactively refer to her as Elizabeth I. However,
Tsar Paul I of Russia,
King Umberto I of Italy,
Emperor Franz Joseph I of Austria,
King Juan Carlos I of Spain,
Emperor Haile Selassie I of Ethiopia and
Pope John Paul I all used the ordinal I (first) during their reigns, even if there was -- at least so far in the case of Paul of Russia, Franz Joseph of Austria, Juan Carlos of Spain or Haile Selassie of Ethiopia -- never a second ruler with the same name. In spoken English, such names are pronounced as "Elizabeth the First", "George the Sixth", etc.
In some countries in Asia, monarchs took or take
era names. While era names as such are not used in many monarchies, sometimes eras are named after a monarch (usually long-lived), or a succession of monarchs of the same name. This is customary; there is no formal or general rule. For example, the whole period during which a succession of four Georges (
George I,
II,
III, and
IV) of the Hanoverian dynasty reigned in Great Britain became known as the
Georgian era. Conversely, although there were many Edwards, the
Edwardian era always refers to the reign of
Edward VII
Edward VII (Albert Edward; 9 November 1841 – 6 May 1910) was King of the United Kingdom and the British Dominions, and Emperor of India, from 22 January 1901 until Death and state funeral of Edward VII, his death in 1910.

, the regnal names of the titled monarchs, who are known locally as the
traditional rulers, serve two very important functions within the
monarchical system. Firstly, seeing as how most states are organised in such a way as to mean that ''all'' of the legitimate descendants of the first man or woman to arrive at the site of any given community are considered its dynastic
heir
Inheritance is the practice of receiving private property, titles, debts, entitlements, privileges, rights, and obligations upon the death of an individual. The rules of inheritance differ among societies and have changed over time. Offi ...
s, their thrones are usually rotated amongst almost endless pools of contending cousins who all share the names of the founders of their houses as primary surnames. In order to tell them all apart from one another, secondary surnames are also used for the
septs of each of the royal families that are eligible for the aforementioned rotations, names that often come from the names of state of the first members of their immediate lineages to rule in their lands. Whenever any of their direct heirs ascend the thrones, they often use their septs' names as reign names as well, using the appropriate ordinals to differentiate themselves from the founders of the said septs. An example of this is found in the kingdom of
Lagos
Lagos ( ; ), or Lagos City, is a large metropolitan city in southwestern Nigeria. With an upper population estimated above 21 million dwellers, it is the largest city in Nigeria, the most populous urban area on the African continent, and on ...
, where the Adeniji-Adele family is distinguished from their numerous Adele cousins by the word ''Adeniji'', which was actually the first name of the reigning founder of their branch of the dynasty, the
Oba Adeniji Adele II. This distinction notwithstanding, both groups of
dynasts (as well as a number of other ones that do not have the name Adele as an official surname, such as that of the Oloye
Adekunle Ojora, a prominent nobleman of royal descent) are part of what is known as the Adele Ajosun Ruling House of Lagos.
Beyond that which is described above, regnal names also serve in Nigeria and indeed in much of Africa as chronological markers in much the same way that those of Europe do (e.g. the ''Victorian'' era). Whenever one hears of a person describing what happened at the time when so and so ruled over any particular place or people, what he or she is actually saying is that an event happened within a finite period of time, one that is equal to the duration of the reign of the monarch in question. Now seeing as how it is possible (and in fact common, particularly among the southern tribes) for one individual to have several different names and aliases in a single life, a certain degree of uniformity in usage is required if the history of an entire state is to be tied to his or her name. It is for this reason that when new monarchs are enthroned, the uniqueness of their names is usually considered to be a matter of considerable importance (even when it is caused by nothing more than the adding of ordinals to them or the allowing of more than a generation to pass before their subsequent usage). An example of this can be found in the
kingdom of Benin
The Kingdom of Benin, also known as Great Benin, is a traditional kingdom in southern Nigeria. It has no historical relation to the modern republic of Benin, which was known as Dahomey from the 17th century until 1975. The Kingdom of Benin's c ...

Erediauwa I became the surname of all of his immediate family in the Eweka royal house of the state, thus nominally tying them and their descendants to the era of his reign.

Akenzua II, and his uncles and their heirs, named the Ewekas after his grandfather
Eweka II.
In the case of the comparatively small number of Nigerian monarchs, such as Obi
Nnaemeka Achebe of
Onitsha, who do not make use of regnal names as a result of a variety of reasons, pre-coronation names are maintained during their reigns.

, Chinese monarchs were frequently accorded posthumous names (; ) after their death. Posthumous names were adjectives originally intended to determine the achievements and moral values, or the lack thereof, of one's life. Since both titles were accorded only after one's death, they were not effectively regnal names. As a result of Chinese cultural and political influence, temple names and posthumous names were adopted by monarchs of Korea and Vietnam, whereas monarchs of Japan adopted only posthumous names.

, it was common for Chinese monarchs to proclaim more than one era name during a single reign, or that a single era name could span the reigns of several rulers. Monarchs of the Ming and
Qing dynasties, however, often adopted only one era name throughout their reign.
Thus, Chinese sovereigns of the Ming and Qing dynasties came to be highly associated with the corresponding era name of their reign and are commonly known by their respective era name with few exceptions, although era names were not effectively regnal names. The era name system was also adopted by rulers of Korea, Vietnam and Japan, with Japan still using the system to this day.
The following table provides examples from China, Japan, Korea and Vietnam to illustrate the differences between monarchical titles in the Sinosphere. Bold characters represent the most common way to refer to the monarchs.

Religious offices
Catholic Church
Immediately after a new pope is elected, and accepts the election, he is asked by the
Dean of the College of Cardinals, "By what name shall you be called?" The new pope chooses the name by which he will be known. The senior Cardinal Deacon, or
Cardinal Protodeacon, then appears on the balcony of
Saint Peter's Basilica to proclaim the new Pope, informing the world of the man elected Pope, and under which name he would be known during his reign.
Annuntio vobis gaudium magnum:
Habemus Papam!
Eminentissimum ac Reverendissimum Dominum,
Dominum orename
Sanctæ Romanæ Ecclesiæ Cardinalem urname
qui sibi nomen imposuit apal name
I announce to you a great joy:
We have a Pope,
The Most Eminent and Most Reverend Lord,
Lord orename
Cardinal of the Holy Roman Church urname
who conferred upon himself the name apal name
During the first centuries of the church, priests elected
bishop of Rome continued to use their baptismal names after their elections. The custom of choosing a new name began in AD 533 with the election of
Mercurius. Mercurius had been named after the Roman god
Mercury, and decided that it would not be appropriate for a pope to be named after a Roman god. Mercurius subsequently decreed that he would be known as John II. Since the end of the tenth century the pope has customarily chosen a new name for himself during his Pontificate; however, until the 16th century some pontiffs used their
baptismal names.
The last pope to use his baptismal name was
Pope Marcellus II in 1555, a choice that was even then quite exceptional. The names chosen by popes are not based on any system other than general honorifics. They have been based on immediate predecessors, mentors, political similarity, or even after family members—as was the case with
Pope John XXIII. The practice of using the baptismal name as papal name has not been ruled out and future popes could elect to continue using their original names after being elected pope.
Often the new pontiff's choice of name upon being elected to the papacy is seen as a signal to the world of whom the new pope will emulate or what policies he will seek to enact. Such is the case with
Benedict XVI who, in fact, explained the
reasons for his choice of name during his first General Audience in St. Peter's Square, on 27 April 2005. On that occasion, he said that he wanted to remember "
Pope Benedict XV, that courageous prophet of peace, who guided the Church through turbulent times of war", and also "
Saint Benedict of Nursia, co-patron of Europe, whose life evokes the Christian roots of Europe".
There has never been a Pope Peter II. Even though there is no specific prohibition against choosing the name Peter, bishops elected to the Papacy have refrained from doing so even if their own given name was Peter. This is because of a tradition that only
Saint Peter should have that honor. In the 10th century
John XIV used the regnal name ''John'' because his given name was Peter. While some
antipopes did take the name Peter II, their claims are not recognized by the mainstream Roman Catholic Church, and each of these men only either has or had a minuscule following that recognized their claims.
Probably because of the controversial
Antipope John XXIII, new popes avoided taking the regnal name John for over 600 years until the election of
Angelo Cardinal Roncalli in 1958. Immediately after his election, there was some confusion as to whether he would be known as John XXIII or John XXIV. Cardinal Roncalli thus moved to immediately resolve by declaring that he would be known as John XXIII.
In 1978,
Albino Luciani became the first pope to use two names for his regnal name when he took the name
John Paul I, including the "I". He took the "John Paul" name to honor both John XXIII and
Paul VI. With the unexpected death of John Paul I a little over a month later,
Karol Wojtyła took the name John Paul II to honor his immediate predecessor.
Antipopes also have regnal names, and also use the ordinal to show their position in the line of previous pontiffs with their names. For example,
David Bawden took the name Michael I when declared pope in 1990.
Coptic Church
Coptic popes also choose regnal names distinct from their given names.
Islamic caliphates
The use of regnal names (
) was uncommon in the
Medieval Islamic era until the
Abbasid Caliphate, when the first Abbasid caliph,
Abu al-Abbas Abdullah ibn Muhammad, who overthrew the
Umayyad dynasty, used the as-Saffah ("the Blood-Shedder"). This name carried a messianic association, a theme that would be continued by as-Saffah's successors.
The use of regnal names among the caliphs lasted throughout the reign of the Abbasid Caliphate, until the institution was deposed after the defeat of the
Mamluk Sultanate and the capture of Caliph
al-Mutawakkil III by the
