Vizier

A vizier ( /vɪˈzɪər/, rarely /ˈvɪzjər/; or وزير‎ in Arabic script (Persian, Urdu and Arabic); Hindi: वज़ीर ; sometimes spelled vazir, vizir, vasir, wazir, vesir, or vezir) is a high-ranking political advisor or minister in an Islamic government. The word derived from the Semitic root W-Z-R ('to help'); the word is mentioned in the Quran. The Abbasid Caliphs give the name title wazir to a minister formerly called Katib (secretary) who was at first merely a helper, afterwards became the representative and successor of the Dapir (official scribe or secretary) of the Sassanian kings.
