• The Vedic cultural tradition do gel with the chiefdom based rural Post-IVC cultures as they also use rice, horse and iron etc. However, it also displays a distinct difference with the IVC as it was an urban civilization, whereas the Vedic Hindu culture was pronounced for the ABSENCE OF fortified cities, town planning and drainage, monumental art and architecture of burnt bricks, advanced specialization and sea trade, use of seals, weights, measures and script and the custom of burying the dead in cemeteries.
Please understand that the IVC had nothing to do with Vedic or Hindu culture and IVC is Pakistani heritage and not Indian.
Mughals when first come they come with foreign armies and ruled south Asia. But centuries later the entire mughal army will be of local people, hindu, muslims. So basically when Mughals were on decline these ded pasli marathas were fighing mughal armies which basically meant local hindu, muslim people. 
Not long after British ruled with same way, conquer one region and give them modern weapons and then to another region. They themselves suffered very few losses over all, most of the times it will be local population.
