I studied British Colonial history in college.
They natives were not the obsequious innocents they are often portrayed to be in literature and film.
For some harrowing reading, read up on the 1857 Indian Mutiny, and pay particular attention to the atrocity at Cawnpore. Some titles are: “The Great Mutiny” by Christopher Hibbert; “Our Bones are Scattered” by Andrew Ward; and “The Great Indian Mutiny” by Richard Collier.
Professor Kakuzo Okakura (1862 -1913) a Japanese philosopher, art expert, curator and author of The Book of Tea and The Ideals of the East, with Special Reference to the Art of Japan wrote:
“We catch a glimpse of the great river of science which never ceases to flow in India. For India has carried and scattered the data of intellectual progress for the whole world, ever since the pre-Buddhist period when she produced the Sankhya philosophy and the atomic theory; the fifth century, when her mathematics and astronomy find their blossom in Arya Bhatta; the seventh when Brahmagupta uses his highly-developed Algebra and makes astronomical observations; the twelfth, brilliant with the glory of Bhaskaracharya, and his famous daughter, down to the nineteenth and twentieth centuries themselves with Ram Chandra the mathematician and Jagdish Chandra Bose the physicist.
Okakura adds that in this scientific age: India had faith.
“Such a faith in its early energy and enthusiasm was the natural incentive to that great scientific age which was to produce astronomers like Aryabhatta, discovering the revolution of the earth on its own axis, and his not less illustrious successor Varahamihira; who brought Hindu medicine to its height, perhaps under Susruta; and which finally gave to Arabia the knowledge with which she was later to fructify Europe.
The religion and culture of China are undoubtedly of Hindu origin. At one time in the single province of loyang there were more than three thousand Indian monks and ten thousand Indian families to impress their national religion and art on Chinese soil.
