Viceroy
A viceroy (/ˈvaɪsrɔɪ/) is an official who reigns over a polity in the name of and as the representative of the monarch of the territory.
The term derives from the Latin prefix vice-, meaning "in the place of" and the Anglo-Norman roy (Old French roi, roy), meaning "king". This denotes the position as one who acts on behalf of a king or monarch. A viceroy's territory may be called a viceroyalty, though this term is not always applied. The adjective form is viceregal, less often viceroyal. The term vicereine is sometimes used to indicate a female viceroy suo jure, although viceroy can serve as a gender-neutral term. Vicereine is more commonly used to indicate a viceroy's wife, known as the viceregal consort.
The term has occasionally been applied to the governors-general of the Commonwealth realms, who are viceregal representatives of the monarch.
The position of a viceroy is by royal appointment rather than a noble rank. An individual viceroy often also held a separate noble title, such as Bernardo de Gálvez, 1st Viscount of Galveston, who was also Viceroy of New Spain.
