Muslim historian Firishta [full name Muhammad Qasim Hindu Shah, born in 1560 and died in 1620], the author of the Tarikh-i Firishta and the Gulshan-i Ibrahim, was the first to give an idea to the medieval bloodbath that was India during Muslim rule, when he declared that over 400 million Hindus got slaughtered during Muslim invasion and occupation of India. Survivors got enslaved and castrated. India’s population is said to have been around 600 million at the time of Muslim invasion. By the mid 1500’s the Hindu population was 200 million.

By the time the British arrived to the shores of India and after centuries of Islamic law ruling India, the Hindu population was not behaving like their normal self; they were behaving like Muslims. There are many witness reports from the British archives of horrendous Hindu incidents that were shocking in cruelty to the British – and they therefore sometimes referred to the people as “savages”. Yes, anyone who gets contaminated by the association with Islamic ‘culture’ truly gets tainted and savaged. That is exactly why it is so detrimental and dangerous.

Today, like other cultures with a soul massacred by Islam, India is not truly a Hindu nation. India is a shadow of Islam, a Hindufied version of Islam, where every human atrocity has been emulated and adopted into a culture previously alien to such brutality. And in association with it’s foreign mohamedan pest, these Islamic habits have become adopted and accepted as a “normal” part of Indian culture. But if we look at pre-Islamic Indian culture it was a in general a benevolent culture of knowledge and learning, much more so than it is today.

From the time of the Umayyad Dynasty (711AD) to  the last Mughal, Bahadur Shah Zafar (1858), so widely praised as great leaders by Indian historians themselves, entire cities were burnt down and the populations massacred, with hundreds of thousands killed in every campaign, and similar numbers deported as slaves. Every new invader made (often literally) his hills of Hindus skulls. Thus, the conquest of Afghanistan in the year 1000 was followed by the annihilation of the Hindu population; the region is still called the Hindu Kush, i.e. “Hindu slaughter.”
