Excerpts from Books and Wikipedia
Muslim monarchs would rule until the Mongol invaders in 1290. [Aldrete: Ancient World]
"But when Ghiyas returned a year later, the outnumbered Ghurids—meeting the Rajputs in the Second Battle of Tarain—outmaneuvered and outfought the Hindu defenders. Prithvi Raj was taken captive and executed. . . . The Ghurids took Delhi in 1193; a Hindu king would not rule there again for four hundred years. In 1199, a Ghurid army reached Bihar, where the last Pala king still clung to the illusion of his power, and destroyed even the last remnants of Pala power.12 In 1202, the Ghurid front reached the empire of the Sena. . . . The confrontation was an anticlimax. Lakshman Sen had inherited not just the Sena empire but the resentment of its people. Oppressed by the overregulation of caste and the slighting of the traditional Buddhist institutions, his subjects welcomed the Ghurids as their deliverers. . . . The Ghurids entered Gaur in triumph, claiming it for their sultan Ghiyas. They faced almost no opposition. The people of Bengal knew little of Islam, but too much of the rigid Hinduism of the Sena; they were ready to embrace the Muslim sultan, if only to rid themselves of the Hindu king."
