History Of Bengal

[Guest]

Let me try to divert the attention from this 'a' debate. One topic of that interest's me about bengal is the lack of rigidity in caste system when compared to rest of India. Since I have little knowledge of history I can make not make much conjectures. My ideas come from a spiritual teacher and it would be good to hear from more experts on the history. It seems the region of bengal or gauda was much like ancient vedic society for a long time with little influence of smartism on social life. It came with raghunandan not much long ago and brahmans were instated from outside. Someone may have already touched upon it. But I would like to know how was our society before smartism (actually shudraism, for raghunandan's version was aimed to give a jolly good times to few brahmins it seems?). What was the social structure and fabric of the society before smartism got it's grip? perhaves this inherent opposition to smartism made bengalis to jump for communist propaganda and doom their fate for ever...not sure, but surely bengali psychology has something dead against smartism. I personally believe in the ancient form of varna system~but medivial rigity was disgusting, it's aim was solely to deprive the majority poors. Any thoughts?
