Other things being equal, it would seem highly desirable not to be conquered, and if conquered and ruled by foreigners, to be rid of them. The ratio of Englishmen/Indians in India was rarely much above 1/1000. Unlike the native Americans encountered by Cortez and Pizarro, the natives of India were if anything less vulnerable to disease than vice-versa. Moreover, the technological advantage of the English was slight or non-existent until well into the nineteenth century.
So why did India suffer itself to be and remain conquered?
