Imperial, royal and noble ranks

Traditional rank amongst European imperiality, royalty, peers, and nobility is rooted in Late Antiquity and the Middle Ages. Although they vary over time and among geographic regions (for example, one region's prince might be equal to another's grand duke), the following is a reasonably comprehensive list that provides information on both general ranks and specific differences. Distinction should be made between reigning (or formerly reigning) families and the nobility – the latter being a social class subject to and created by the former.

English titles
During the Middle Ages, in England, as in most of Europe, the feudal system was the dominant social and economic system. Under the feudal system, the monarch would grant land to the monarch’s loyal subjects in exchange for the subject’s loyalty and military service when called by the monarch. Besides grants of land, these subjects were usually given titles that implied nobility and rank, such as Duke, Earl, Baron, etc, which were passed down through the holder’s male line. Barons were the lowest rank of nobility and were granted small parcels of land. Earls were the next highest rank with larger land holdings. Dukes were the highest rank and held the largest holdings, known as duchies. The monarch was the ultimate authority and was able to grant and revoke titles.

In the 14th century, an English peerage began to emerge as a separate entity from the feudal system. The peers held titles granted by the monarch, but did not necessarily hold any land or have any feudal obligations. The peerage was divided into five ranks; from highest to lowest: Duke, Marquess, Earl, Viscount, and Baron.

The peerage system became more formalized over time. By the 18th century, peerages were no longer granted as a reward for military service, but instead were granted as a way to recognize social status and political influence.

Today, there are two types of peerages in England: hereditary and life peerages. Hereditary peerages are those that are passed down through the male line of the family. Life peerages, on the other hand, are granted to an individual for their lifetime only and do not pass down to their heirs.

Before 1958, life peerages were relatively rare, and were held not to entitle the bearer to sit in the House of Lords. Since the Life Peerages Act 1958, nearly all new peerages are life baronies.

In addition to peerages, there are also a number of honorary titles in England. These titles do not carry any legal or social privileges, but are instead granted as a way to recognize individuals for their contributions to society.

Some common honorary titles include Knighthood, Damehood, and Companion of Honour. These titles are granted by the monarch and are not hereditary.

Sovereign

 * The word monarch is derived from the Greek μονάρχης, monárkhēs, "sole ruler" (from μόνος, mónos, "single" or "sole", and ἄρχων, árkhōn, "archon", "leader", "ruler", "chief", the word being the present participle of the verb ἄρχειν, árkhein, "to rule", "to lead", this from the noun ὰρχή, arkhē, "beginning", "authority", "principle") through the Latinized form monarcha.
 * The word sovereign is derived from the Latin super ("above").
 * Autocrat is derived from the Greek αὐτοκράτωρ: αὐτός ("self") and κρατείν ("to hold power"), and may be translated as "one who rules by themself".

Many titles listed may also be used by lesser nobles – non-sovereigns – depending on the historical period and state.

In the Ottoman Empire, the Grand Vizier held the imperial seal and could convene all other viziers (ministers) to attend to affairs of the state; the viziers in conference were called "Kubbealtı viziers" in reference to their meeting place, the Kubbealtı ('under the dome') in Topkapı Palace.

It was a court title, bestowed by the monarch to highest military commander, usually reserved for the most influential and most capable among highest Bosnian nobility.    To interpret it as an office post rather than a court rank could be equally accurate, and although it was retained for life by a nobleman who gained it, it was not meant to be hereditary, at least not at first. However, in the last several decades of the Bosnian medieval state it became hereditary, which means it became more than just an office or a court rank.  The feminine form is Grand Duchess

The feminine form is Archduchess.

The female equivalent is a Dayang. (Cf. also Principalía – the hispanized and Christianized Datu class during the Spanish colonial period in the Philippines.) Esta institucion (Cabecería de Barangay), mucho más antigua que la sujecion de las islas al Gobierno, ha merecido siempre las mayores atencion. En un principio eran las cabecerías hereditarias, y constituian la verdadera hidalguía del país; mas del dia, si bien en algunas provincias todavía se tramiten por sucesion hereditaria, las hay tambien eleccion, particularmente en las provincias más inmediatas á Manila, en donde han perdido su prestigio y son una verdadera carga. En las provincias distantes todavía se hacen respetar, y allí es precisamente en donde la autoridad tiene ménos que hacer, y el órden se conserva sin necesidad de medidas coercitivas; porque todavía existe en ellas el gobierno patriarcal, por el gran respeto que la plebe conserva aún á lo que llaman aquí principalía. (Translation: This institution (Cabecera de Barangay), much older than the fastening of the islands to the Government, has always deserved the most attention. In the beginning, they were the hereditary heads, and they constituted the true chivalry of the country; but of the day, although in some provinces they are still transacted by hereditary succession, there are also elections, particularly in the provinces closest to Manila, where they have lost their prestige and are a real burden. In the distant provinces they are still enforced, and that is precisely where authority has less to do, and the order is preserved without the need for coercive measures; because the patriarchal government still exists in them, because of the great respect that the plebs still retain for what they call here principalía.FERRANDO.)

This did not necessarily mean that the Caliph was himself the supreme authority on Islamic law or theology; that still fell to the Ulema. The role of the Caliph was to oversee and take responsibility for the Muslim community's political and governmental needs (both within and beyond the borders of his territorial realm), rather than to himself determine matters of doctrine.
 * Amir al-Mu'minin, or "Commander (Emir) of the Faithful," a title traditionally held by the Caliphs of Islam to denote their suzerainty over all Muslims, even (theoretically) those beyond their territorial borders.

In this context, imams may lead Islamic worship services, lead prayers, serve as community leaders, and provide religious guidance. Thus for Sunnis, anyone can study the basic Islamic sciences and become an Imam
 * Dalai Lama, the highest authority in Tibetan (or more specifically Gelug) Buddhism and a symbol of the unification of Tibet, said to belong to a line of reincarnations of the bodhisattva Avalokitesvara.

Other sovereigns, royalty, peers, and major nobility
Several ranks were widely used (for more than a thousand years in Europe alone) for both sovereign rulers and non-sovereigns. Additional knowledge about the territory and historic period is required to know whether the rank holder was a sovereign or non-sovereign. However, joint precedence among rank holders often greatly depended on whether a rank holder was sovereign, whether of the same rank or not. This situation was most widely exemplified by the Holy Roman Empire (HRE) in Europe. Several of the following ranks were commonly both sovereign and non-sovereign within the HRE. Outside of the HRE, the most common sovereign rank of these below was that of Prince. Within the HRE, those holding the following ranks who were also sovereigns had (enjoyed) what was known as an immediate relationship with the Emperor. Those holding non-sovereign ranks held only a mediate relationship (meaning that the civil hierarchy upwards was mediated by one or more intermediaries between the rank holder and the Emperor).

Titles

 * Prince (Prinz in German), junior members of a royal, grand ducal, ruling ducal or princely, or mediatised family. The title of Fürst was usually reserved, from the 19th century, for rulers of principalities—the smallest sovereign entities (e.g., Liechtenstein, Lippe, Schwarzburg, Waldeck-and-Pyrmont)—and for heads of high-ranking, noble but non-ruling families (Bismarck, Clary und Aldringen, Dietrichstein, Henckel von Donnersmarck, Kinsky, Paar, Pless, Thun und Hohenstein, etc.). Cadets of these latter families were generally not allowed to use Prinz, being accorded only the style of count (Graf) or, occasionally, that of Fürst (Wrede, Urach) even though it was also a ruling title. Exceptional use of Prinz was permitted for some morganatic families (e.g., Battenberg, Montenuovo) and a few others (Carolath-Beuthen, Biron von Kurland). Prince is also used as the highest, non-royal title of nobility in instances such as that of Prince Bernadotte where Swedish royal princes lost those titles due to unapproved marriages.

Minor nobility, landed gentry, and other aristocracy
The distinction between the ranks of the major nobility (listed above) and the minor nobility, listed here, was not always a sharp one in all nations. But the precedence of the ranks of a Baronet or a Knight is quite generally accepted for where this distinction exists for most nations. Here the rank of Baronet (ranking above a Knight) is taken as the highest rank among the ranks of the minor nobility or landed gentry that are listed below.

 * Skartabel is a minor Polish aristocrat.
 * Scottish Baron is a hereditary feudal nobility dignity, outside the Scots peerage, recognised by Lord Lyon as a member of the Scots noblesse and ranking below a Lord of Parliament but above a Scottish Laird in the British system.

In Germany, the constitution of the Weimar Republic in 1919 ceased to accord privileges to members of dynastic and noble families. Their titles henceforth became legal parts of the family name, and traditional forms of address (e.g., "Hoheit" or "Durchlaucht") ceased to be accorded to them by governmental entities. The last title was conferred on 12 November 1918 to Kurt von Kleefeld. The actual rank of a title-holder in Germany depended not only on the nominal rank of the title, but also the degree of sovereignty exercised, the rank of the title-holder's suzerain, and the length of time the family possessed its status within the nobility (Uradel, Briefadel, altfürstliche, neufürstliche, see: German nobility). Thus, any reigning sovereign ranks higher than any deposed or mediatized sovereign (e.g., the Fürst of Waldeck, sovereign until 1918, was higher than the Duke of Arenberg, head of a mediatized family, although Herzog is nominally a higher title than Fürst). However, former holders of higher titles in extant monarchies retained their relative rank, i.e., a queen dowager of Belgium outranks the reigning Prince of Liechtenstein. Members of a formerly sovereign or mediatized house rank higher than the nobility. Among the nobility, those whose titles derive from the Holy Roman Empire rank higher than the holder of an equivalent title granted by one of the German monarchs after 1806.

In Austria, nobility titles may no longer be used since 1918.
