Given proximity, its not very surprising that there has been an African presence in India from very early on. Pakistan for e.g. has a large number of people of African origin, as does Gujarat (the Siddis).
As early as in the 13th century, Africans in India had a political presence. Apart from ruling small principalities in Janjira and Sachin, it was in medieval Deccan that they had a powerful role as military commanders and prime ministers , e.g. Malik Ambar in Ahmednagar and Ikhlas Khan in Bijapur (both from Ethiopia). Ikhlas Khan in particular, linked as he was to the Adil Shahis, was much painted. See also [X] [X] and [X].
