Lists of ancient kings are organized by region and peoples, and include kings recorded in ancient history (3000 BC – 1700 AD) and in mythology.
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 king. 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".
These are lists of incumbents, including heads of states or of subnational entities.
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.
The Chinese sovereign was the ruler of a particular monarchical regime in the historical periods of ancient China and imperial China. Sovereigns ruling the same regime, and descended from the same paternal line, constituted a dynasty. Several titles and naming schemes have been used throughout Chinese history.
Temple names are posthumous titles accorded to monarchs of the Sinosphere for the purpose of ancestor worship. The practice of honoring monarchs with temple names began during the Shang dynasty in China and had since been adopted by other dynastic regimes in the Sinosphere, with the notable exception of Japan. Temple names should not be confused with era names (年號), regnal names (尊號) or posthumous names (謚號).
A posthumous name is an honorary name given mainly to revered dead people in East Asian culture. It is predominantly used in Asian countries such as China, Korea, Vietnam, Japan, and Thailand. Reflecting on the person's accomplishments or reputation, the title is assigned after death and essentially replaces the name used during life. Although most posthumous names are given to royalty, some posthumous names are given to honour significant people without hereditary titles, such as courtiers or military generals.
A vassal state is any state that has a mutual obligation to a superior state or empire, in a status similar to that of a vassal in the feudal system in medieval Europe. Vassal states were common among the empires of the Near East, dating back to the era of the Egyptian, Hittite, and Mitanni conflict, as well as in ancient China.
A regnal name, regnant name, or reign name is the name used by monarchs and popes during their reigns and subsequently, historically. Since ancient times, some monarchs have chosen to use a different name from their original name when they accede to the monarchy.
King of Kings was a ruling title employed primarily by monarchs based in the Middle East and the Indian subcontinent. Commonly associated with Iran, especially the Achaemenid and Sasanian Empires, the title was originally introduced during the Middle Assyrian Empire by king Tukulti-Ninurta I and was subsequently used in a number of different kingdoms and empires, including the aforementioned Persia, various Hellenic kingdoms, India, Armenia, Georgia, and Ethiopia.
A regnal year is a year of the reign of a sovereign, from the Latin regnum meaning kingdom, rule. Regnal years considered the date as an ordinal, not a cardinal number. For example, a monarch could have a first year of rule, a second year of rule, a third year of rule, and so on, but not a zeroth year of rule.
A regnal list or king list is, at its simplest, a list of successive monarchs. Some regnal lists may give the relationship between successive monarchs, the length of reign of each monarch or annotations on important reigns. The list may be divided into dynasties marked off by headings. As a distinct genre, the regnal list originates in the ancient Near East. Its purpose was not originally chronological. It originally served to demonstrate the antiquity and legitimacy of the monarchy, but it became an important device for structuring historical narratives and thus a chronological aid.
The 1922 regnal list of Ethiopia is an official regnal list used by the Ethiopian monarchy which names over 300 monarchs across six millennia. The list is partially inspired by older Ethiopian regnal lists and chronicles, but is notable for additional monarchs who ruled Nubia, which was known as Aethiopia in ancient times. Also included are various figures from Greek mythology and the Biblical canon who were known to be "Aethiopian", as well as figures who originated from Egyptian sources.
Regnal lists of Ethiopia are recorded lists of monarchs who are claimed by tradition to have ruled Ethiopia. These lists are often recorded on manuscripts or orally by monasteries and have been passed down over the centuries.
