I agree history is written by the victor,not in the sense he can change the collective conscious which is represented by the mythology and folklore but because,more fundamentally,he designs the history books which form part of the school curriculum.This is because as it happened in India a formal study of history started happening only when the British introduced the Western education in India with all the distortions inherent in it. It therefore follows that not all history studied in history books is right .For a correct perception of the historical events one must sift the truth by a proper balance between written history and other indigenous sources like parchments , other unorganised evidences like stone and copper inscriptions,literature ,folklore etc.
