A Vizier (????, sometimes also spelled Vizir, Wasir, Wazir, Wesir - grammatical vowel changes are common in many oriental languages)

It is common, even among historians, to apply 'modern' terms to cultures whose own authentical titles are (or were when the habit took root) unsufficiantly known, in this case to pre-islamic Antiquity.

• In ancient Egypt the second most civilian statesman after the pharaoh was the vizier, acting as a chancellor. However at times the viceroy of Nubia (a rather military governor general, sometimes a prince of the pharoah's blood) and/or the Highpriest of Amun rose to equal or even superior power, some pharaohs are even believed to have lost real political preeminence to the 'kingmakers'.
• Among the Huns, the vizier was the second officer in rank after the great king; nor formal status is known, just a class of royal councilors, representatives etc. known by he Greek term logades. Attila the Hun's vizier was Onegesius.
