Isn't this a quite common pattern in history repeating itself? Including the reaction of the historians, to gloss over it? The pattern that, a cohort of a society that under previous rule didn't have any right nor representation, acquire that as a side-effect during invasion of competing faction. Often under brutal circumstances, but the effect can be clearly seen if you how a society change during such over-hauling effect. Japans invasion of South-east Asia comes to mind. Mostly for their own benefit, installing puppet-government, but it seems to be a contributing factor to decolonization of SEA of European influence. Depending on the source you read, this is probably glossed over to great deal. I assume you can probably find similar cases in places like Spain (Reconquest), Christianization of East/North Europe, Islamic conquest of Middle East/Indus etc.
