Islamic conquest after the death of the
prophet of the Muslims, Mohammad, was probably the most bloodiest in
the history of mankind. One of the greatest historians who wrote the
Story of Civilization, Volume 4: The Age of Faith (Our Oriental Heritage) in a
multi-volume series, Will Durant, wrote objectively as he
wrote about the dark history of Christianity during what is called
the medieval period:
The Islamic conquest of India is probably the bloodiest story in history. It is a discouraging tale, for its evident moral is that civilization is a precious good, whose delicate complex of order and freedom, culture and peace, can at any moment be overthrown by barbarians invading from without or multiplying within.
