The word emperor can mean the male ruler of an empire. Empress, the female equivalent, may indicate an emperor's wife, mother/grandmother, or a woman who rules in her own right and name. Emperors are generally recognized to be of the highest monarchic honor and rank, surpassing kings. In Europe, the title of Emperor has been used since the Middle Ages, considered in those times equal or almost equal in dignity to that of Pope due to the latter's position as visible head of the Church and spiritual leader of the Catholic part of Western Europe. The emperor of Japan is the only currently reigning monarch whose title is translated into English as "Emperor".
Theophanu was empress of the Holy Roman Empire by marriage to Emperor Otto II, and regent of the Empire during the minority of their son, Emperor Otto III, from 983 until her death in 991. She was the niece of the Byzantine Emperor John I Tzimiskes. She was known to be a forceful and capable ruler. Her status in the history of the Empire in many ways was exceptional. According to Wilson, "She became the only consort to receive the title 'co-empress', and it was envisaged she would succeed as sole ruler if Otto II died without a son."
The 930s decade ran from January 1, 930, to December 31, 939.
The Holy Roman Emperor, originally and officially the Emperor of the Romans during the Middle Ages, and also known as the Roman-German Emperor since the early modern period, was the ruler and head of state of the Holy Roman Empire. The title was held in conjunction with the title of king of Italy from the 8th to the 16th century, and, almost without interruption, with the title of king of Germany throughout the 12th to 18th centuries.
Tsarina or tsaritsa is the title of a female autocratic ruler (monarch) of Bulgaria, Serbia or Russia, or the title of a tsar's wife. The English spelling is derived from the German czarin or zarin, in the same way as the French tsarine / czarine, and the Spanish and Italian czarina / zarina. (A tsar's daughter is a tsarevna.)
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.
Fürst is a German word for a ruler as well as a princely title. Fürsten were, starting in the Middle Ages, members of the highest nobility who ruled over states of the Holy Roman Empire and later its former territories, below the ruling Kaiser (emperor) or König (king).
Shahbanu was the title for empress regnant or empress consort in Persian and other Iranian languages. The two Sassanian empresses regnant, Boran and Azarmidokht, c. 630, were the last two that carried the title before Farah Pahlavi, the wife of Mohammad Reza Pahlavi, the last Shah of Iran (Persia), assumed the title for the first time since the Muslim conquest of Persia in the 7th century.
King of Italy was the title given to the ruler of the Kingdom of Italy after the fall of the Western Roman Empire. The first to take the title was Odoacer, a barbarian military leader, in the late 5th century, followed by the Ostrogothic kings up to the mid-6th century. With the Frankish conquest of Italy in the 8th century, the Carolingians assumed the title, which was maintained by subsequent Holy Roman Emperors throughout the Middle Ages. The last Emperor to claim the title was Charles V in the 16th century. During this period, the holders of the title were crowned with the Iron Crown of Lombardy.
Archduke was the title borne from 1358 by the Habsburg rulers of the Archduchy of Austria, and later by all senior members of that dynasty. It denotes a rank within the former Holy Roman Empire (962–1806), which was below that of Emperor, and roughly equal to King, Prince-Archbishop, Grand prince and Grand Duke, but above that of a Sovereign Prince and Duke.
A queen regnant is a female monarch, equivalent in rank, title and position to a king. She reigns suo jure over a realm known as a kingdom; as opposed to a queen consort, who is married to a reigning king; or a queen regent, who is the guardian of a child monarch and rules pro tempore in the child's stead or instead of her husband who is absent from the realm, be it de jure in sharing power or de facto in ruling alone. A queen regnant is sometimes called a woman king. A princess regnant is a female monarch who reigns suo jure over a principality; an empress regnant is a female monarch who reigns suo jure over an empire.
Majesty is used as a manner of address by many monarchs, usually kings or queens. Where used, the style outranks the style of (Imperial/Royal) Highness, but is inferior to the style of Imperial Majesty. It has cognates in many other languages, especially of Europe.
A king-emperor is a sovereign ruler who is simultaneously a king of one territory and emperor of another. This title usually results from a merger of a royal and imperial crown, but recognises the two territories as different politically and culturally as well as in status. It also denotes a king's imperial status through the acquisition of an empire or vice versa.
The Kingdom of Italy, also called Imperial Italy, was one of the constituent kingdoms of the Holy Roman Empire, along with the kingdoms of Germany, Bohemia, and Burgundy. It originally comprised large parts of northern and central Italy. Its original capital was Pavia until the 11th century.
King is the title given to a male monarch in a variety of contexts. A king is an absolute monarch if he holds the powers of government without control, or the entire sovereignty over a nation; he is a limited monarch if his power is restrained by fixed laws; and he is an absolute, when he holds the whole legislative, judicial, and executive power, or when the legislative or judicial powers, or both, are vested in other people by the king. Kings are hereditary sovereigns when they hold the powers of government by right of birth or inheritance, and elective when raised to the throne by choice.
The grand title of the emperor of Austria was the official list of the crowns, titles, and dignities which the emperors of Austria carried from the foundation of the empire in 1804 until the end of the monarchy in 1918.
