Temporary massive removal of some legendary history 

There were quite a few paragraphs discussing the ancient origins of the Yadavs, but as I was picking my way through it, it appeared a well-nigh impenetrable mass of confusing data, and likely a lot of WP:Synthesis. Terms such as Yadava/Yadav, Ahir/Yadav, and Abhira/Ahir were frequently conflated, and it appeared at many (most?) times that info was included without regard for whether the cited author gave any indication that his topic involved the modern Yadav caste. The info is not "lost", it is cleanly preserved in the History tab, and its removal noted in Edit Summary and here so that any inclined editor can go back through it and carefully select the appropriate portions to re-incorporate. I submit that any info not specifically related to the modern Yadav go into the appropriate other articles such as Yadava and Abhira, etc. and that only material clearly linking the modern Yadavs to those ancient roots be included here. Otherwise, lengthy explanations of past groups with no clear link to the present group constitutes Synthesis, as it implies/pre-supposes a factual linkage when one may not be specified.

Again, I'm not trying to permanently wipe out this info, I just think the section was very unwieldy and contentious, and rather than pick and chip at it, it's better to temporarily wipe the slate clean, and then mine the past drafts to incorporate any usable data.
