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 honour 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".
A monarch is a head of state for life or until abdication, and therefore the head of state of a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Usually a monarch either personally inherits the lawful right to exercise the state's sovereign rights or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may proclaim oneself monarch, which may be backed and legitimated through acclamation, right of conquest or a combination of means.
A monarchy is a form of government in which a person, the monarch, reigns as head of state for life or until abdication. The extend of the authority of the monarch may vary from restricted and largely symbolic, to fully autocratic, and may have representational, executive, legislative, and judicial functions.
The Holy Roman Emperor, originally and officially the Emperor of the Romans during the Middle Ages, and also known as the Romano-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.
A coronation is the act of placement or bestowal of a crown upon a monarch's head. The term also generally refers to the ceremony which marks the formal investiture of a monarch with regal power. In addition to the crowning, this ceremony may include the presentation of other items of regalia, and other rituals such as the taking of special vows by the new monarch, the investing and presentation of regalia to them, and acts of homage by the new monarch's subjects. In certain Christian denominations, such as Lutheranism and Anglicanism, coronation is a religious rite. As such, Western-style coronations have often included anointing the monarch with holy oil, or chrism as it is often called; the anointing ritual's religious significance follows examples found in the Bible. The monarch's consort may also be crowned, either simultaneously with the monarch or as a separate event.
A crown prince or hereditary prince is the heir apparent to the throne in a royal or imperial monarchy. The female form of the title, crown princess, is held by a woman who is heir apparent or is married to the heir apparent.
An elective monarchy is a monarchy ruled by a monarch who is elected, in contrast to a hereditary monarchy in which the office is automatically passed down as a family inheritance. The manner of election, the nature of candidate qualifications, and the electors vary from case to case. Historically, it was common for elective monarchies to transform into hereditary ones by repeated election of the previous rulers' children, or for hereditary monarchies to acquire elective or semi-elective succession laws, particularly following dynastic crises.
In many historical societies, the position of kingship carried a sacral meaning and was identical with that of a high priest and judge. Divine kingship is related to the concept of theocracy, although a sacred king need not necessarily rule through his religious authority; rather, the temporal position itself has a religious significance behind it. The monarch may be divine, become divine, or represent divinity to a greater or lesser extent.
King of the Romans was the title used by the king of East Francia following his election by the princes from the reign of Henry II (1002–1024) onward.
The Kingdom of the Franks, also known as the Frankish Kingdom, the Frankish Empire or Francia, was the largest post-Roman barbarian kingdom in Western Europe. It was ruled by the Frankish Merovingian and Carolingian dynasties during the Early Middle Ages. Francia was among the last surviving Germanic kingdoms from the Migration Period era.
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 warlord, 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.
Basileus is a Greek term and title that has signified various types of monarchs throughout history. In the English-speaking world it is perhaps most widely understood to mean 'monarch', referring to either a 'king' or an 'emperor'. The title was used by sovereigns and other persons of authority in ancient Greece, the Byzantine emperors, and the kings of modern Greece. The name Basileios (Basil), deriving from the term basileus, is a common given name in the Eastern Orthodox Church and Eastern Catholic Churches.
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, duchess, or grand duchess regnant is a female monarch who reigns suo jure over a principality or (grand) duchy; an empress regnant is a female monarch who reigns suo jure over an empire.
East Francia or the Kingdom of the East Franks was a successor state of Charlemagne's empire ruled by the Carolingian dynasty until 911. It was created through the Treaty of Verdun (843) which divided the former empire into three kingdoms.
The Franks were a western European people during the Roman Empire and Middle Ages. They began as a Germanic people who lived near the Lower Rhine, on the northern continental frontier of the empire. They subsequently expanded their power and influence during the Middle Ages, until much of the population of western Europe, particularly in and near France, were commonly described as Franks, for example in the context of their joint efforts during the Crusades starting in the 11th century. A key turning point in this evolution was when the Frankish Merovingian dynasty based within the collapsing Western Roman Empire first became the rulers of the whole region between the rivers Loire and Rhine, and then subsequently imposed power over many other post-Roman kingdoms both inside and outside the old empire.
The Kingdom of Germany or German Kingdom was the mostly Germanic language-speaking East Frankish kingdom, which was formed by the Treaty of Verdun in 843. The king was elected, initially by the rulers of the stem duchies, who generally chose one of their own. After 962, when Otto I was crowned emperor, East Francia formed the bulk of the Holy Roman Empire, which also included the Kingdom of Italy and, after 1032, the Kingdom of Burgundy.
In the European history, monarchy was the prevalent form of government throughout the Middle Ages, only occasionally competing with communalism, notably in the case of the maritime republics and the Swiss Confederacy.
The monarchy of Italy was the system of government in which a hereditary constitutional monarch was the sovereign of the Kingdom of Italy from 1861 to 1946.
The order of precedence among European monarchies was a much-contested theme of European history, until it lost its salience following the Congress of Vienna in 1815.
