Ottoman-Mughal ties faded by the late 16th century as Europeans rerouted trade

Evidence

On the whole, Ottoman relations with India after the 16th century seem to have been infrequent and of relatively minor importance. There was a time, during the reign of Suleyman the Magnificent, when the Ottomans were for a while actively concerned with the affairs of south Asia. Towards the end of the 16th century, however, they withdrew from active participation, and thereafter their links with India were chiefly commercial—and even these began to weaken, as the Western powers established themselves more firmly in the East and di­ verted a good deal of the trade from the Middle Eastern transit routes to the open ocean. — Bernard Lewis, From Babel to Dragomans, 622
