نظام الملك
According to a Seljuk vizier, Nizam al-Mulk, by the reign of Malik-Shah I, the sovereign had a large army at his disposal. There were Turkmens, mamluks, a standing army, infantry and the sultan's personal guard. Nizam al-Mulk also estimated Malik-Shah’s forces at 400,000 men, and often opposed cost-cutting plans (instituted by Taj al-Mulk) to bring these to 70,000.
