“Mohammed Ghori had the Hindu temples of Ajmer demolished and ordered the construction of mosques and Quran schools on their ruins…He plundered Kanauj and Kashi and destroyed their temples… [While his generals] destroyed in passing the remaining Buddhist communities of Bihar and destroyed the universities of Nalanda…. Bakhtiar Khilji “established a Muslim capital in Lakhanauti (Gaur) on the Ganga and destroyed, in 1197, its basalt temples. In Odantpuri, in 1202, he massacred two thousand Buddhist monks…. [Meanwhile, back in Delhi:] “This Quwwat-ul-Islam (Might of Islam) was built in a hurry using the debris, chiefly sculpted pillars, of twenty-seven dismantled Hindu temples.” Thirty years later, “Iltutmish did not forget that he was a Muslim conqueror. He showed himself to be very pious, never forgetting to do his five devotional daily…. He likewise showed himself totally intolerant vis-à-vis the Hindus who refused to convert, destroying their temples and annihilating Brahmin communities.””
