"Ghulams" were appointed to high positions within the royal household, and by the end of Shah Abbas' reign, one-fifth of the high-ranking amirs were ghulams. By 1598 already an ethnic Georgian from Safavid-ruled Georgia, well known by his adopted Muslim name after conversion, Allahverdi Khan, had risen to the position of commander-in-chief of all Safavid armed forces. and by that became one of the most powerful men in the empire. The offices of "wakil" and "amir al-umarā" fell in disuse and were replaced by the office of a "Sipahsālār" (, "master of the army"), commander-in-chief of all armed forces – Turcoman and Non-Turcoman – and usually held by a Persian ("Tādjik") noble.
