Imperial, royal and noble ranksTraditional rank amongst European 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.
Grand duchyA grand duchy is a country or territory whose official head of state or ruler is a monarch bearing the title of grand duke or grand duchess. Prior to the early 1800s, the only Grand duchies in Europe were located in what is now Italy: Tuscany (declared in 1569) and Savoy (in 1696). During the 19th century there were as many as 14 grand duchies in Europe at once (a few of which were first created as exclaves of the Napoleonic empire but later re-created, usually with different borders, under another dynasty).
NobilityNobility is a social class found in many societies that have an aristocracy. It is normally 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.
Prince of the Holy Roman EmpirePrince of the Holy Roman Empire (princeps imperii, Reichsfürst, cf. Fürst) was a title attributed to a hereditary ruler, nobleman or prelate recognised as such by the Holy Roman Emperor. Originally, possessors of the princely title bore it as immediate vassals of the Emperor who held a fief (secular or ecclesiastical) that had no suzerain except the Emperor. However, by the time the Holy Roman Empire was abolished in 1806, there were a number of holders of Imperial princely titles who did not meet these criteria.
Russian nobilityThe Russian nobility (дворя́нство) arose in the Middle Ages. In 1914 it consisted of approximately 1,900,000 members (about 1.1% of the population) in the Russian Empire. Up until the February Revolution of 1917, the noble estates staffed most of the Russian government and possessed a Gentry assembly. The Russian word for nobility, dvorianstvo (), derives from Slavonic dvor (двор), meaning the court of a prince or duke (kniaz), and later, of the tsar or emperor. Here, dvor originally referred to servants at the estate of an aristocrat.
Style (form of address)A style of office or form of address, also called manner of address, is an official or legally recognized form of address for a person or other entity (such as a government or company), and may often be used in conjunction with a personal title. A style, by tradition or law, precedes a reference to a person who holds a post or political office, and is sometimes used to refer to the office itself. An honorific can also be awarded to an individual in a personal capacity.
