And 1937 Burma "partition"? Please do note we are talking about a entity called British India. You know the one with a Viceroy, poncy English and British flag etc etc. Please try not to confuse it with Indian Republic - even if it carries similar name.
Why don't we use Mauryan Empire instead? By extension of your logic, should present day Biharis rule Pakistan because of the simple fact that Mauryans did so too?
British Empire has nothing to do with this or other topics but you seem to keep bringing them up. Why not just stick with glorifying Ghazni and others who brought "light" of Islam to Pakistani landmass?
This conqueror-worship never stops with you people
