Do not think that in ancient India people were living peacefully. There were always wars, oppression based on caste, drought, diseases,etc,etc. In Tamilnadu for example chera,chola and pandya were always engaged in/prepare for war. Think how many people would have been killed/injured in wars. Masters (read brahmins) of hinduism did not allow others to get educated, did not allow others to enter temples, did not allow others to read vedas. Kings were merely puppets at their hands. In Travancore kingdom majority of the people were branded as low-castes and their women were not allowed to cover their upp@r-body. Can you believe this? But it happened. Read Indian history properly.
