What type of rule did india adopt from the british

The very idea of the British Raj—the British rule over India—seems inexplicable today. Consider the fact that Indian written history stretches back almost 4,000 years, to the civilization centers of the Indus Valley Culture at Harappa and Mohenjo-Daro. Also, by 1850, India had a population of at least 200 million.

Britain, on the other hand, had no indigenous written language until the 9th century CE (almost 3,000 years after India). Its population was about 21 million in 1850.2  How, then, did Britain manage to control India from 1757 to 1947? The keys seem to have been superior weaponry, economic power, and Eurocentric confidence.
