aurangzebs empire was larger than that of akbar and without the help of hindu kings he would not have been able to rule this vast country. so he had to rely on the hindu kings and generals ,to use their armies and keep them fighting among each other, in this he was a cunning and brilliant strategist but definitely not secular. thats precisely the reason why the moghul empre collapsed after his death, those hindu kings who had joined him out of fear immediately shifted loyalties and no longer supported his sons, so mughals lost control over much of india.
7 .aurangzebs reign was marred by large scale rebellions all over the country, Sikhs , Jats , Marathas , Gujratis ,assamese all were rebelling simultaneously. even afghans/pashtuns rebelled against aurangzebs atrocities. ( he sent rajputs to crush pashtuns) his predecessors like akbar did not have to face this large scale rebellion. this being the case aurangzeb was smart enough to understand that his mughal/muslim soldiers were not numerically enough to quell all the rebellions simultaneously all over this vast country. so he had to depend on hindu generals. it was a marriage of convenience and not very different from the shameless political alliances and coalitions we see in india today .
