It might have been the Mauryas but we don’t have enough details of how the common man lived in the Mauryan empire. The arthashastra seems like our best source. Both the Mughals and the British had their share of evils against the common population but my sense is that if you were Hindu you were better off in the British empire than the Mughal Empire except for the rare tolerant Mughal ruler (eg ; Akbar).
