Decline of Buddhism in the Indian subcontinent
The decline of Buddhism in the Indian subcontinent has been attributed to various factors, especially the regionalisation of India after the end of the Gupta Empire (320–650 CE), which led to the loss of patronage and donations, and a competition with Hinduism and Jainism; and the conquest and subsequent persecutions by Huns, Turks and Persians.
- There can be no doubt that the fall of Buddhism in India was due to the invasions of the Musalmans. Islam came out as the enemy of the 'But'. The word 'But' as everybody knows, is the Arabic word and means an idol. Thus the origin of the word indicates that in the Moslem mind idol worship had come to be identified with the Religion of the Buddha. To the Muslims, they were one and the same thing. The mission to break the idols thus became the mission to destroy Buddhism. Islam destroyed Buddhism not only in India but wherever it went. Before Islam came into being Buddhism was the religion of Bactria, Parthia, Afghanistan, Gandhar, and Chinese Turkestan, as it was of the whole of Asia. In all these countries Islam destroyed Buddhism.

- The Mussalman invaders sacked the Buddhist universities of Nalanda, Vikramshila, Jagaddala, Odantapuri to name only a few. They razed to the ground Buddhist monasteries with which the country was studded. The monks fled away in thousands to Nepal, Tibet and other places outside India. A very large number were killed outright by the Muslim commanders. How the Buddhist priesthood perished by the sword of the Muslim invaders has been recorded by the Muslim historians themselves. Summarizing the evidence relating to the slaughter of the Buddhist Monks perpetrated by the Musalman General in the course of his invasion of Bihar in 1197 AD, Mr. Vincent Smith says, "The Musalman General, who had already made his name a terror by repeated plundering expeditions in Bihar, seized the capital by a daring stroke... Great quantities of plunder were obtained, and the slaughter of the 'shaven headed Brahmans', that is to say the Buddhist monks, was so thoroughly completed, that when the victor sought for someone capable of explaining the contents of the books in the libraries of the monasteries, not a living man could be found who was able to read them. 'It was discovered,' we are told, 'that the whole of that fortress and city was a college, and in the Hindi tongue they call a college Bihar.' "Such was the slaughter of the Buddhist priesthood perpetrated by the Islamic invaders. The axe was struck at the very root. For by killing the Buddhist priesthood, Islam killed Buddhism. This was the greatest disaster that befell the religion of the Buddha in India....

- Religion like any other ideology can be attained only by propaganda. If propaganda fails, religion must disappear. The priestly class, however detestable it may be, is necessary to the sustenance of religion. For it is by its propaganda that religion is kept up. Without the priestly class religion must disappear. The sword of Islam fell heavily upon the priestly class. It perished or it fled outside India. Nobody remained to keep the flame of Buddhism burning. It may be said that the same thing must have happened to the Brahmanical priesthood. It is possible, though not to the same extent. But there is this difference between the constitution of the two religions and the difference is so great that it contains the whole reason why Brahmanism survived the attack of Islam and why Buddhism did not. This difference relates to the constitution of the clergy. The Brahmin priesthood has a most elaborate organization. Every Brahmin is a potential priest of Brahmanism and be drafted in service when the need be. There is nothing to stop the rake’s life and progress. This is not possible in Buddhism. A person must be ordained in accordance with established rites by priests already ordained, before he can act as a priest. After the massacre of the Buddhist priests, ordination became impossible so that the priesthood almost ceased to exist. Some attempt was made to fill the depleted ranks of the Buddhist priests. New recruits for the priesthood had to be drawn from all available sources. They certainly were not the best.

- When you consider that the establishment of Islam in the entire area from Iran to Ningxia and from Kazakhstan to Malaysia, including India, was followed by the complete disappearance of living Buddhism in each of these regions, you may wonder what Prof. Thapar’s definition of "dialogue" could be. Even Moghul Emperor Akbar, who invited representatives of many religions to his court for discussion, did not invite any Buddhist representative simply because Buddhism did not exist in India at that time.

- From 986 CE, the Muslim Turks started raiding northwest India from Afghanistan, plundering western India early in the eleventh century. Forced conversions to Islam were made, and Buddhist images smashed, due to the Islamic dislike of idolatry. Indeed in India, the Islamic term for an 'idol' became 'budd'.

- The tremendous complex at Sarnath which had grown up on the site of the first Buddhist sermon was wrecked beyond recovery, thus ending a continuous tradition of refuge and meeting-place for ascetics which went back to the centuries before Buddha.

- Khalji’s military exploits in the east also resulted in conversions to Islam. About the end of the twelfth or the beginning of the thirteenth century, he marched into Bihar and attacked the University centres of Nalanda, Vikramshila and Uddandapur, erecting a fortress at the site of Uddandapur or Odantapuri. The Buddhist monks in these places were massacred and the common people, deprived of their priests and teachers, turned some to Brahmanism and some to Islam. Buddhism did not die out immediately or completely in Bihar. But Bakhtiyar’s raid on Bihar did deliver a shattering blow to Buddhism and its lost followers were gained mainly by Islam.

- After winning the final battle, when the Muslims rushed violently, like a stormy wind, through Sindh, they went on beheading these Buddhists even more ruthlessly than they did the Vedic Hindus. For, the Vedic Hindus were fighting in groups or individually at every place and so they struck at least a little awe and terror in the minds of the Muslims. But as there was no armed opposition in Buddhist Vihars and Buddhist localities, the Muslims cut them down as easily as they would cut vegetable.

- But today the fashion is to ascribe the extinction of Buddhism to the persecution of Buddhists by Hindus, to the destruction of their temples by the Hindus. One point is that the Marxist historians who have been perpetrating this falsehood have not been able to produce even an iota of evidence to substantiate the concoction...
And look at the finesse of these historians. They maintain that such facts and narratives must be swept under the carpet in the interest of national integration: recalling them will offend Muslims, they say, doing so will sow rancour against Muslims in the minds of Hindus, they say. Simultaneously, they insist on concocting the myth of Hindus destroying Buddhist temples. Will that concoction not distance Buddhists from Hindus? Will that narrative, specially when it does not have the slightest basis in fact, not embitter Hindus?

- As if this is not enough, there is a deliberate and organised design to convert Kargil's Buddhists to Islam. In the last four years, about 50 girls and married women with children were allured and converted from village Wakha alone. If this continues unchecked, we fear that Buddhists will be wiped out from Kargil in the next two decades or so. Anyone objecting to such allurement and conversions is harassed... Therefore, to protect the religious and cultural identity of the Ladakhi people, an anti-conversion law must be enacted for Kargil as is presently in force in states like Arunachal Pradesh and Madhya Pradesh.

- During the sixth and early seventh centuries AD the whole tract was controlled by Turkish rulers, but in the course of the seventh, with increasing strength of the T'ang Emperors, China gained control. Finally, however, under the onslaught of Islam, from the eighth century to the tenth, both Buddhist and Manichaean as well as the Nestorian Christian culture and monuments of the region were destroyed... In the north very little survives of the ancient edifices that were there prior to the Muslim conquest: only a few mutilated religious sites remain. It is clear from Indian literature that both temples and images must have existed in the second century BC and perhaps earlier. Very little architectural evidence remains, however, antedating the epoch of the Gupta dynasty (C. AD 320-650), for it was precisely in the Ganges Valley, the central and chief area of the Gupta empire, that the Muslim empire flourished a millennium later and most of the monuments above ground were destroyed by the sectarian zeal of Islam. The oldest stone ruins that have been found represent not the beginnings of a style, but fully developed forms... Since the earliest important body of Indian art surviving to us stems from the century of Asoka, it is predominantly Buddhist. During subsequent periods, however, Buddhist and Hindu (Brahmanical) themes alternate in rich profusion. The two traditions flourished side by side, even sharing colleges and monasteries, for nearly two millenniums, until about the height of the Muslim conquest (c. AD 1200), Buddhism disappeared from the land of its birth.
