Nobility is a social class found in many societies that have an aristocracy. It is normally appointed by and ranked immediately below royalty. Nobility has often been an estate of the realm with many exclusive functions and characteristics. The characteristics associated with nobility may constitute substantial advantages over or relative to non-nobles or simply formal functions (e.g., precedence), and vary by country and by era. Membership in the nobility, including rights and responsibilities, is typically hereditary and patrilineal.
Membership in the nobility has historically been granted by a monarch or government, and acquisition of sufficient power, wealth, ownerships, or royal favour has occasionally enabled commoners to ascend into the nobility.
There are often a variety of ranks within the noble class. Legal recognition of nobility has been much more common in monarchies, but nobility also existed in such regimes as the Dutch Republic (1581–1795), the Republic of Genoa (1005–1815), the Republic of Venice (697–1797), and the Old Swiss Confederacy (1300–1798), and remains part of the legal social structure of some small non-hereditary regimes, e.g., San Marino, and the Vatican City in Europe. In Classical Antiquity, the nobiles (nobles) of the Roman Republic were families descended from persons who had achieved the consulship. Those who belonged to the hereditary patrician families were nobles, but plebeians whose ancestors were consuls were also considered nobiles. In the Roman Empire, the nobility were descendants of this Republican aristocracy. While ancestry of contemporary noble families from ancient Roman nobility might technically be possible, no well-researched, historically documented generation-by-generation genealogical descents from ancient Roman times are known to exist in Europe.
Hereditary titles and styles added to names (such as "Prince", "Lord", or "Lady"), as well as honorifics, often distinguish nobles from non-nobles in conversation and written speech. In many nations, most of the nobility have been untitled, and some hereditary titles do not indicate nobility (e.g., vidame). Some countries have had non-hereditary nobility, such as the Empire of Brazil or life peers in the United Kingdom.
The term derives from Latin nobilitas, the abstract noun of the adjective nobilis ("noble" but also secondarily "well-known, famous, notable"). In ancient Roman society, nobiles originated as an informal designation for the political governing class who had allied interests, including both patricians and plebeian families (gentes) with an ancestor who had risen to the consulship through his own merit (see novus homo, "new man").
In modern usage, "nobility" is applied to the highest social class in pre-modern societies. In the feudal system (in Europe and elsewhere), the nobility were generally those who held a fief, often land or office, under vassalage, i.e., in exchange for allegiance and various, mainly military, services to a suzerain, who might be a higher-ranking nobleman or a monarch. It rapidly became a hereditary caste, sometimes associated with a right to bear a hereditary title and, for example in pre-revolutionary France, enjoying fiscal and other privileges.
While noble status formerly conferred significant privileges in most jurisdictions, by the 21st century it had become a largely honorary dignity in most societies, although a few, residual privileges may still be preserved legally (e.g. Spain, UK) and some Asian, Pacific and African cultures continue to attach considerable significance to formal hereditary rank or titles. (Compare the entrenched position and leadership expectations of the nobility of the Kingdom of Tonga.) More than a third of British land is in the hands of aristocrats and traditional landed gentry.
Nobility is a historical, social, and often legal notion, differing from high socio-economic status in that the latter is mainly based on pedigree, income, possessions, or lifestyle. Being wealthy or influential cannot ipso facto make one noble, nor are all nobles wealthy or influential (aristocratic families have lost their fortunes in various ways, and the concept of the "poor nobleman" is almost as old as nobility itself).
Although many societies have a privileged upper class with substantial wealth and power, the status is not necessarily hereditary and does not entail a distinct legal status, nor differentiated forms of address. Various republics, including European countries such as Greece, Turkey, and Austria, and former Eastern Bloc countries and places in the Americas such as Mexico and the United States, have expressly abolished the conferral and use of titles of nobility for their citizens. This is distinct from countries that have not abolished the right to inherit titles, but which do not grant legal recognition or protection to them, such as Germany and Italy, although Germany recognizes their use as part of the legal surname. Other countries and authorities allow their use, but forbid attachment of any privilege thereto, e.g., Finland, Norway, and the European Union, while French law also protects lawful titles against usurpation.
Not all of the benefits of nobility derived from noble status per se. Usually privileges were granted or recognized by the monarch in association with possession of a specific title, office or estate. Most nobles' wealth derived from one or more estates, large or small, that might include fields, pasture, orchards, timberland, hunting grounds, streams, etc. It also included infrastructure such as a castle, well and mill to which local peasants were allowed some access, although often at a price. Nobles were expected to live "nobly", that is, from the proceeds of these possessions. Work involving manual labor or subordination to those of lower rank (with specific exceptions, such as in military or ecclesiastic service) was either forbidden (as derogation from noble status) or frowned upon socially. On the other hand, membership in the nobility was usually a prerequisite for holding offices of trust in the realm and for career promotion, especially in the military, at royal court and often the higher functions in the government, judiciary and church.
Prior to the French Revolution, European nobles typically commanded tribute in the form of entitlement to cash rents or usage taxes, labor or a portion of the annual crop yield from commoners or nobles of lower rank who lived or worked on the noble's manor or within his seigneurial domain. In some countries, the local lord could impose restrictions on such a commoner's movements, religion or legal undertakings. Nobles exclusively enjoyed the privilege of hunting. In France, nobles were exempt from paying the taille, the major direct tax. Peasants were not only bound to the nobility by dues and services, but the exercise of their rights was often also subject to the jurisdiction of courts and police from whose authority the actions of nobles were entirely or partially exempt. In some parts of Europe the right of private war long remained the privilege of every noble.
During the early Renaissance, duelling established the status of a respectable gentleman and was an accepted manner of resolving disputes.
Since the end of World War I the hereditary nobility entitled to special rights has largely been abolished in the Western World as intrinsically discriminatory, and discredited as less efficient than individual meritocracy in allocating societal resources. Nobility came to be associated with social rather than legal privilege, expressed in a general expectation of deference from those of lower rank. By the 21st century even that deference had become increasingly minimized. In general, the present nobility present in the European monarchies has no more privileges than the citizens decorated in republics.
In France, a seigneurie (lordship) might include one or more manors surrounded by land and villages subject to a noble's prerogatives and disposition. Seigneuries could be bought, sold or mortgaged. If erected by the crown into, e.g., a barony or countship, it became legally entailed for a specific family, which could use it as their title. Yet most French nobles were untitled ("seigneur of Montagne" simply meant ownership of that lordship but not, if one was not otherwise noble, the right to use a title of nobility, as commoners often purchased lordships). Only a member of the nobility who owned a countship was allowed, ipso facto, to style himself as its comte, although this restriction came to be increasingly ignored as the ancien régime drew to its close.
