In the administration of justice he was inflexible, showing no favour to his brethren or children, to his associates or attendants. - Ghiyas ud din Balban

Muslim power in India suffered a serious setback after Iltutmish. Balban had to battle against a revival of Hindu power. The Katehar Rajputs of what came to be known as Rohilkhand in later history, had so far refused to submit to Islamic imperialism. Balban led an expedition across the Ganges in 1254 AD. According to Badauni, “In two days after leaving Delhi, he arrived in the midst of the territory of Katihar and put to death every male, even those of eight years of age, and bound the women.” But in spite of such wanton cruelty, Muslim power continued to decline till the Khaljis revived it after 1290 AD.

Sultan Ghiyasu-d Balban was a man of experience in matters of government.

Sultan Balban, while he was a Khan, was addicted to wine drinking.
