Emir

Emir, also transliterated as amir, is a word of Arabic origin that can refer to a male monarch, aristocrat, holder of high-ranking military or political office, or other person possessing actual or ceremonial authority. The title has a history of use in West Asia, East Africa, West Africa, Central Asia, and South Asia. In the modern era, when used as a formal monarchical title, it is roughly synonymous with "prince", applicable both to a son of a hereditary monarch, and to a reigning monarch of a sovereign principality, namely an emirate. The feminine form is emira, with the same meaning as "princess".
Prior to its use as a monarchical title, the term "emir" was historically used to denote a "commander", "general", or "leader". In contemporary usage, "emir" is also sometimes used as either an honorary or formal title for the head of an Islamic, or Arab organisation or movement.
Qatar and Kuwait are the only independent countries which retain the title "emir" for their monarchs. In recent years, the title has been gradually replaced by "king" by contemporary hereditary rulers who wish to emphasize their secular authority under the rule of law. A notable example is Bahrain, whose monarch changed his title from emir to king in 2002. Whereas the titular United Arab Emirates use the title Sheikh instead of Emir for their subnational rulers.

Origins

Amir, meaning "lord" or "commander-in-chief", is derived from the Arabic root , meaning "command". Originally simply meaning "commander", it came to be used as a title of leaders, governors, or rulers of smaller states. In modern Arabic the word is analogous to the title "Prince". The word entered English in 1593, from the French émir.
