Queen regnant

A queen regnant (pl.: queens regnant) is a female monarch, equivalent in rank, title and position to a king. She reigns suo jure (in her own right) 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.

A queen regnant possesses all the powers, such as they may be, of the monarchy, whereas a queen consort or queen regent shares her spouse's or child's rank and titles but does not share the sovereignty of her spouse or child. The husband of a queen regnant traditionally does not share the queen regnant’s rank, title, or sovereignty and usually holds a lower princely title. However, the concept of a king consort is not unheard of in both contemporary and historical periods.

A queen dowager or empress dowager is the widow of a king or emperor; a queen mother is a queen dowager who is also the mother of a reigning sovereign.

Since the abdication of Margrethe II of Denmark on 14 January 2024, there are currently no female sovereigns in the world. This is the first time this has been the case in over 200 years.

The oldest attested queen regnant was the Pharaoh Sobekneferu from the 18th/17th century BC.

In ancient Africa, ancient Persia, Asian and Pacific cultures, and in some European countries, female monarchs have been given the title king or its equivalent, such as pharaoh, when gender is irrelevant to the office, or else have used the masculine form of the word in languages that have grammatical gender as a way to classify nouns. The Roman Empress Irene of Athens sometimes titled herself basileus (βασιλεύς), 'emperor', rather than basilissa (βασίλισσα), 'empress', and Mary of Hungary was crowned as Rex Hungariae, King of Hungary in 1382.

Among the Davidic Monarchs of the Kingdom of Judah, there is mentioned a single queen regnant, Athaliah, though the Hebrew Bible regards her negatively as a usurper. The much later Hasmonean Queen Salome Alexandra (Shlom Tzion) was highly popular.^{[citation needed]}

Accession of a queen regnant occurs as a nation's order of succession permits. Methods of succession to kingdoms, tribal chiefships, and such include nomination (the reigning monarch or a council names an heir), primogeniture (in which the children of a monarch or chief have preference in order of birth from eldest to youngest), and ultimogeniture (in which the children have preference in the reverse order of birth from youngest to eldest). The scope of succession may be matrilineal, patrilineal, or both; or, rarely, open to general election when necessary. The right of succession may be open to men and women, or limited to men only or to women only.
