Every student of Indian history is familiar with the extraordinary event, quite unique in the annals of the Muslim dynasties in India, which took place in 1537, when Burhān Niẓām Shāh, the Sunni ruler of the Ahmadnagar state, in the Deccan, proclaimed Shi'ism the official religion of his kingdom. Indian historians offer only “popular” explanations for this important step, attributing it to religious zeal or the superstitious fears of the prince. It appears, however, that Burhān Niẓām Shāh (who reigned from 914/1508 to 961/1554), though nothing exceptional, was, nevertheless, quite a reasonable and statesmanlike ruler, who would hardly permit his religious emotions to carry him too far. It is therefore permissible to suspect some weightier motives behind this act, in the form of considerations connected with the policy of the then ascendant dynasty of the Safavids of Persia, which still remain unrevealed. As is known, both Shah Ismā'īl and Ṭahmāsp used to take much interest in Indian politics. In all this the central figure, who inspired the policy of Burhān Niẓām Shāh, was the rather enigmatic personality of a Persian emigrant, a learned theologian, philosopher, poet, stylist, and politician, Shāh Ṭāhir, surnamed Dakkanī and Ḥusaynī. It would be very interesting to study every side of his activities. This, however, would carry us too far; the present note is only intended to draw attention to quite an unexpected circumstance which presents this already extraordinary historical figure in a still more extraordinary light: some materials, recently discovered in Badakhshan, reveal that in reality he was regarded as an Ismaili Imam, a successor of the khudāwands of Alamūt, in a schismatic line of the Imams, which became extinct about two hundred years ago.
