Vizier

An illustrated Portrait of Mohammad Shah Qajar and his Vizier Haji Mirza Aqasi in Iran during the 19th century. Vizier's roles as advisors in courts evolved over time, becoming an important part of official government institutions.

Historically, a vizier (/ˈvɪziər/; Arabic: وزير, romanized: wazīr; Persian: وزیر, romanized: vazīr), also transliterated as wazir, is a high-ranking political advisor or minister in the countries of "greater Persia". The Abbasid caliphs gave the title wazir to a minister formerly called katib (secretary), who was at first merely a helper but afterwards became the representative and successor of the dapir (official scribe or secretary) of the Sasanian kings.

In modern usage, the term has been used for government ministers in much of West Asia, South Asia, North Africa, and beyond. Several alternative spellings are used in English, such as vizir, wazir, and vezir.
