What historical effects would we have seen if India had had help in throwing out the British circa 1870's - 1890's? I am working towards a set of ideas for some after 1900 timeline outlines, but need to have the British out of India before WWI, and preferably for at least 20 years. The reason I am posting this in this forum rather than the 'before 1900' forum is, I don't want to focus on how this comes about, but rather what the effects of such a change would have had by 1900 and beyond.
What I am specifically looking for here is, what if the UK were disallowed any direct trade with the former 'British India', and their ships were banned from Indian waters and ports. Effectively, India would become an independent nation. What would we see different by the time of 1900's in terms of reduced power and wealth for the empire as a whole compared to OTL?
