===Reason for the three tags===

I have placed three tags on the "Backgound to the Controversy" section. This section cannot be the place to debate the case of AIT supporters or opponents. Please note that the article is about the historical etc. aspects of AIT. For debates, please see Indo-Aryan migration. But I request people not to go there just to put their partisan points of view. I have noticed some such statements in this section.
