Acrown princeorhereditary prince is the heir apparent to the throne in a royal or imperial monarchy. The female form of the title is crown princess, which may refer either to an heiress apparent or, especially in earlier times, to the wife of the person styled crown prince.
Crown prince as a descriptive term has been used throughout history for the prince who is first-in-line to a throne and is expected to succeed (i.e. the heir apparent), barring any unforeseen future event preventing this. In certain monarchies, a more specific substantive title may be accorded and become associated with the position of heir apparent (e.g. Prince of Wales in the United Kingdom, Prince of Asturias in the Kingdom of Spain and formerly the DauphininFrance). In these monarchies, the term crown prince may be used less often than the substantive title (or never).
Until the late twentieth century, no modern monarchy adopted a system whereby females would be guaranteed to succeed to the throne (i.e. absolute primogeniture). A crown princess would therefore be more likely to refer to the spouse of a crown prince. She would be styled crown princess, not in her own right but by courtesy.
Today, in monarchies lower than royal rank the term "crown prince" is used in English (e.g. Crown Prince of Umm al-Quwain).
The term crown prince is not used in European monarchies if the hereditary sovereign holds a title below that of king/queen or emperor/empress (such as grand dukeorprince), although it is sometimes used as a synonym for heir apparent.[citation needed]
In Europe, where primogeniture governed succession to all monarchies except those of the Papacy and Andorra, the eldest son or (more recently) eldest child of the current monarch fills the role of crown prince or princess, depending upon whether females of the dynasty enjoy personal succession rights. Male precedence has been abolished in Belgium, Denmark, Luxembourg, Norway, Sweden, the Netherlands and the United Kingdom.[a][b] The eldest living child of a monarch is sometimes not the heir apparent or crown prince, because that position can be held by a descendant of a deceased older child who, by "right of representation", inherits the same place in the line of succession that would be held by the ancestor if he or she were still living (for example, Carl Gustaf, Duke of Jämtland was the crown prince of Sweden from 1950 to 1973, as the senior grandson by male primogeniture of King Gustaf VI Adolf of Sweden, although the former Prince Sigvard, Duke of Uppland was Gustaf VI Adolf's eldest living son, and Prince Bertil, Duke of Halland his eldest living dynastic son during those years).
In some monarchies, those of the Middle East for example, in which primogeniture is not the decisive factor in dynastic succession, a person may not possess the title or status of crown prince by right of birth, but may obtain (and lose) it as a result of an official designation made on some other legal or traditional basis, such as former crown prince Hassan bin TalalofJordan.
Compare heir apparent and heir presumptive. In Scandinavian kingdoms, the heir presumptive to the crown may hold a different title from an heir apparent: hereditary prince (German: Erbprinz, French: prince héréditaire). It is also the title borne by the heir apparent of Liechtenstein, as well as the heir apparent or presumptive of Monaco. In Luxembourg, the heir apparent bears the title of hereditary grand duke (German: Erbgroßherzog, Luxembourgish: ierfgroussherzog); along with hereditary prince, it was also the title borne by the heirs apparent to the thrones of the grand duchies, sovereign duchies and principalities, and of mediatized princely families in the Germanmonarchies abolished in 1918.
Prince of Orange (Netherlands), whether or not the equivalent title is held by the spouse of the titleholder is decided by the Dutch parliament (e.g., Queen Máxima of the Netherlands was never titled Princess of Orange by marriage for this reason)
Some monarchies have used (although not always de jure) a territorial title for heirs apparent which, though often perceived as a crown princely title, is not automatically hereditary. It generally requires a specific conferral by the sovereign, which may be withheld.
