The destruction of the famed universities of Nalanda and Vikramshila is historically attributed to Bakhtiyar Khalji, a Turkish military general under the Ghurid Empire. In the late 12th century (circa 1193 CE), Bakhtiyar Khalji led devastating raids in Bihar and Bengal, including the sacking of the Buddhist educational centers. Nalanda and Vikramshila, two renowned centers of Buddhist learning, were looted, and their extensive libraries were set on fire. This event significantly contributed to the decline of Buddhism in India. Contemporary sources such as Minhaj-i-Siraj’s Tabaqat-i-Nasiri detail Bakhtiyar’s campaigns and his attack on these institutions. Bakhtiyar Khalji is therefore most accurately identified as the person responsible for this wanton destruction.
