(Redirected from Co-principality)A 'coregency' is the situation where a monarchical position (such as King, Queen, Emperor or Empress), normally held by only a single person, is held by two.
Historical examples of this include the coregency of Frederick I of Austria and Louis the Bavarian over the Holy Roman Empire, and the coregency of
William and Mary over England, Scotland, and Ireland. It was also found in the ancient
Roman Empire.
The city of
Maastricht was under the joint jurisdiction (
parage) of the
duke of Brabant and the
prince-bishop of Liège. In
1648 it became a real
condominium of two independent states, the
Principality of Liège and the republic of the
United Provinces. The coregency or 'co-principality' of the last was no longer held by a person but by the
Estates-General of the Netherlands (until 1794).
A similar situation still exists today in
Andorra, which has two
Princes (the Bishop of Urgel and the President of France), but since they only hold the rank of Prince, not King, it is referred to as a co-principality rather than a coregency.
In
Ancient Egypt, mainly in the Middle Kingdom, the
Pharaoh occasionally appointed his successor (often one of his sons) as coregent, or joint king, to ensure a smooth succession. The Pharaoh also did this when he was elderly or unable to rule his country on his own (such as the case of
Thutmose III and
Amenhotep II or
Amenemhat II and
Senusret II). The existence of the practice makes establishing firm dates in
Egyptian chronology more of a challenge, as the lengths of coregencies are often uncertain and complicate the use of accepted regnal lengths to establish dates.
In the book ''The Mysterious Numbers of the Hebrew Kings'',
Edwin R. Thiele proposed coregency as a possible explanation for discrepancies in the dates given in the
Hebrew Bible for the reigns of the kings of
Israel and
Judah. At least one coregency is explicitly documented in the Bible: the coronation of
King Solomon occurred before the death of his father
David.
Several instances of coregency is also known from Norwegian history in the 12th century.
