Rohilkhand

"Firoz Tughlak, foiled in his attempt to seize' Khargu, who fled to Kumaun, appointed an Afghan governor at Sambhal with orders to invade the country of Katehar every year, to commit every kind of ravage and devastation, and not to allow it to be inhabited until tire murderer was given up."

"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."

"When Balban became the sultan "large sections of the male population were massacred in Katehar and, according to Barani, in villages and jungles heaps of human corpses were left rotting"."

"Although Jalaluddin Khalji was an old and vacillating king, even he did not just remain content with expressing rage at the fact of not being able to deal with the Hindus according to the law. During six years of his reign (June 1290 -July 1296), he mounted expeditions and captured prisoners. While suppressing the revolt of Malik Chhajju, a scion of the dynasty he had ousted, he marched towards Bhojpur in Farrukhabad district and ruthlessly attacked Hindus in the region of Katehar (later Rohilkhand)."
