Qais Faqiri

“Mahmud’s highly mobile army rarely fell below the force of 100,000 that he amassed to attack Balkh in 999.5 In recruiting and deploying his slave soldiers, Mahmud was blind to color, ethnicity, and religion. He did not hesitate, for example, to send Hindu forces against the Turkic, Persian, or Indian armies that were defending Muslim cities. Even his own household consisted mainly of slaves. Far from being constrained by his Muslim faith, Mahmud believed that the highest religious authority, the caliph, had validated his actions and confirmed all the dubious privileges he so freely exercised.”
