How was a tiny country like Britain able to conquer & rule India so easily for so long?

I get that the British brought civilisation to India along with indoor toilets, sewer systems and ended a lot of barbaric Indian customs. Of course Indian women were happy to be British concubines to British soldiers & civil servants, most pale skinned Indians are the descendants of British fathers. Did Indian men feel inferior to their conquerors or just happy with British rule?, I mean India is huge and there were only a few thousand British soldiers and civil servants running the country at any given time. Though the country hasn't been as well run since.
