Imperial, royal and noble ranks in the context of "Venetian patriciate"

Sovereign is a title that can be applied to the highest leader in various categories. The word is borrowed from Old French souverain, which is ultimately derived from the Latin superānus, meaning 'above'.

The roles of a sovereign vary from monarch, ruler or head of state to head of municipal government or head of a chivalric order. As a result, the word sovereignty has more recently also come to mean independence or autonomy.

The Mexican nobility were a hereditary nobility of Mexico, with specific privileges and obligations determined in the various political systems that historically ruled over the Mexican territory.

The term is used in reference to various groups throughout the entirety of Mexican history, from formerly ruling indigenous families of the pre-Columbian states of present-day Mexico, to noble Mexican families of Spanish (as well as Mestizo) and other European descent, which include conquistadors and their descendants (ennobled by King Philip II in 1573), untitled noble families of Mexico, and holders of titles of nobility acquired during the Viceroyalty of the New Spain (1521–1821), the First Mexican Empire (1821–1823), and the Second Mexican Empire (1862–1867); as well as bearers of titles and other noble prerogatives granted by foreign powers who have settled in Mexico.

A Peerage is a form of crown distinction, with Peerages in the United Kingdom comprising both hereditary and lifetime titled appointments of various ranks, which form both a constituent part of the legislative process and the British honours system within the framework of the Constitution of the United Kingdom.

The peerage forms the highest rung of what is termed the "British nobility". The term peerage can be used both collectively to refer to this entire body of titled nobility (or a subdivision thereof), and individually to refer to a specific title (modern English language-style using an initial capital in the latter case but not the former). British peerage title holders are termed peers of the Realm. "Lord" is used as a generic term to denote members of the peerage; however, individuals who use the appellation Lord or Lady are not always necessarily peers (for example some judicial, ecclesiastic and others are often accorded the appellation "Lord" or "Lady" as a form of courtesy title as a product of their office).

A queen consort is the wife of a reigning king, and usually shares her spouse's social rank and status. She holds the feminine equivalent of the king's monarchical titles and may be crowned and anointed, but historically she does not formally share the king's political and military powers, unless on occasion acting as regent.

In contrast, a queen regnant is a female monarch who rules suo jure (Latin for, "in her own right") and usually becomes queen by inheriting the throne upon the death of the previous monarch.

A peerage is a legal system historically comprising various hereditary titles (and sometimes non-hereditary titles) in a number of countries, and composed of assorted noble ranks.

Eyalets (Ottoman Turkish: ایالت, pronounced [ejaːˈlet], lit. 'province'), also known as beylerbeyliks or pashaliks, were the primary administrative divisions of the Ottoman Empire.

From 1453 to the beginning of the nineteenth century the Ottoman local government was loosely structured. The empire was at first divided into states called eyalets, presided over by a beylerbey (title equivalent to duke in English and Amir al Umara in Arabic) of three tails (feathers borne on a state officer's ceremonial staff). The grand vizier was responsible for nominating all the high officers of state, both in the capital and the states. Between 1861 and 1866, these eyalets were abolished, and the territory was divided for administrative purposes into vilayets (provinces).
