Emirate(redirected from Imarah)
Also found in: Dictionary, Thesaurus, Financial.
in Muslim countries, a state or possession ruled by an emir. In the Arabian Caliphate the ruler of an emirate was appointed or confirmed by the caliph; subsequently, various states, both independent and vassal states, were called emirates, including Nejd, Shammar, Asir, and, today, the United Arab Emirates. Whether a particular state formation is designated an emirate depends on established tradition.
