An emirate is a political territory that is ruled by a dynastic Islamic monarch styled emir. It also means principality.
Etymologically emirate or amirate (Arabic: إمارة imārah, plural: إمارات imārāt) is the quality, dignity, office or territorial competence of any emir (prince, commander, governor etc.).
The United Arab Emirates is a federal state that comprises seven federal emirates, each administered by a hereditary emir, these seven forming the electoral college for the federation's President and Prime Minister. As most emirates have either disappeared, been integrated in a larger modern state or changed their rulers' styles, e.g. to malik (Arabic for king) or sultan, such true emirate-states have become rare.
Furthermore, in Arabic the term can be generalized to mean any province of a country that is administered by a member of the ruling class, especially of a member (usually styled emir) of the royal family, as in Saudi Arabian governorates.
