[1] In a related sense, now not commonly used, all more or less sovereign rulers over a state, including kings, were "princes" in the language of international politics.
In this sense, a prince is a ruler of a territory that is sovereign or quasi-sovereign, i.e., exercising substantial (though not all) prerogatives associated with monarchs of independent nations, such as the immediate states within the historical boundaries of the Holy Roman Empire.
As a title, by the end of the medieval era, prince was borne by rulers of territories that were either substantially smaller than those of or exercised fewer of the rights of sovereignty than did emperors and kings.
Lords who exercised lawful authority over territories and people within a feudal hierarchy were also sometimes regarded as princes in the general sense, especially if they held the rank of count or higher.
This is attested in some surviving styles for e.g., British earls, marquesses, and dukes are still addressed by the Crown on ceremonial occasions as high and noble princes (cf.
In parts of the Holy Roman Empire in which primogeniture did not prevail (e.g., Germany), all legitimate agnates had an equal right to the family's hereditary titles.
This tended to proliferate unwieldy titles (e.g. Princess Katherine of Anhalt-Zerbst; Karl, Count Palatine of Zweibrücken-Neukastell-Kleeburg; or Prince Christian Charles of Schleswig-Holstein-Sonderburg-Plön-Norburg) and, as agnatic primogeniture gradually became the norm in the Holy Roman Empire by the end of the 18th century, another means of distinguishing the monarch from other members of his dynasty became necessary.
The custom spread through the Continent to such an extent that a renowned imperial general who belonged to a cadet branch of a reigning ducal family, remains best known to history by the generic dynastic title, "Prince Eugene of Savoy".
Always facing the scepticism of Saint-Simon and like-minded courtiers, these quasi-royal aristocrats' assumption of the princely title as a personal, rather than territorial, designation encountered some resistance.
[4] The post-medieval rank of gefürsteter Graf (princely count) embraced but elevated the German equivalent of the intermediate French, English and Spanish nobles.
In the Holy Roman Empire, these nobles rose to dynastic status by preserving from the Imperial crown (de jure after the Peace of Westphalia in 1648) the exercise of such sovereign prerogatives as the minting of money; the muster of military troops and the right to wage war and contract treaties; local judicial authority and constabulary enforcement; and the habit of inter-marrying with sovereign dynasties.
In Brazil, Portugal and Spain, however, the husband of a female monarch is accorded the masculine equivalent of her title (e.g., emperor, king), at least after he fathered her heir.
In previous epochs, husbands of queens regnant were often deemed entitled to the crown matrimonial, sharing their consorts' regnal title and rank jure uxoris.
However, in cultures which allow the ruler to have several wives (e.g., four in Islam) or official concubines (e.g., Imperial China, Ottoman Empire, Thailand, the Zulu monarchy), these women, sometimes collectively referred to as a harem, often have specific rules determining their relative hierarchy and a variety of titles, which may distinguish between those whose offspring can be in line for the succession or not, or specifically who is mother to the heir to the throne.
Other examples are (e)mirza(da), khanzada, nawabzada, sahibzada, shahzada, sultanzada (all using the Persian patronymic suffix -zada, meaning "son, descendant").
In some dynasties, a specific style other than prince has become customary for dynasts, such as fils de France in the House of Capet, and Infante.
These included the princedoms of Arches-Charleville, Boisbelle-Henrichemont, Chalais, Château-Regnault, Guéménée, Martigues, Mercœur, Sedan, Talmond, Tingrey, and the "kingship" of Yvetot,[7] among others.
Though these offices may not be reserved legally for members of the ruling dynasty, in some traditions they are filled by dynasts, a fact which may be reflected in the style of the office, e.g. "prince-president" for Napoleon III as French head of state but not yet emperor, or "prince-lieutenant" in Luxembourg, repeatedly filled by the crown prince before the grand duke's abdication, or in form of consortium imperii.
[citation needed] In Ukraine, landlords and rulers of Kievan Rus' were called князь (knjazʹ), translated as "prince".
[11] In each case, the title is followed (when available) by the female form and then (not always available, and obviously rarely applicable to a prince of the blood without a principality) the name of the territory associated with it, each separated by a slash.
Princes of the Zhou dynasty were specifically referred to as Wangzi (王子) and Wangsun (王孫), which mean "son of the king" and "grandson of the king," while princes of the vassal states were referred to as Gongzi (公子) and Gongsun (公孫), which mean "son of the lord" and "grandson of the lord," respectively.
Sons of the vassals may receive nobility titles like Jun (君), Qing (卿), Daifu (大夫) and Shi (仕).
[14] As noble titles no longer exist in modern Korea, the English word "Prince" is now usually translated as wangja (왕자, 王子, lit.
Princes and principalities in continental Europe are almost always confused with dukes and duchies in Korean speech, both being translated as gong (공, 公, lit.
In the former Empire of India, during the British Colonial Era, the title of a Prince was conferred upon by the Emperor to the hereditary Indian rulers of the numerous principalities of varying sizes in the empire called "princely states", who ruled their territories in the name of the Emperor of India, who was also simultaneously the Monarch of the United Kingdom and the Dominions.
They acknowledged the Emperor as their imperial sovereign till the empire's dissolution in 1947 and subsequently acceded to the newly formed Union of India and the Dominion of Pakistan between 1947 and 1949.
Those who were born of a king and had a royal mother (a queen or princess consort) are titled Chaofa Chai (Thai: เจ้าฟ้าชาย: literally, "Male Celestial Lord").
In states with an element of theocracy, this can affect princehood in several ways, such as the style of the ruler (e.g. with a secondary title meaning son or servant of a named divinity), but also the mode of succession (even reincarnation and recognition).
