Hughly was captured in 1632. Seven years later the British built their factory at Madras, on the coast of Coromandel. At every Portuguese settlement in Southern India the slave trade was still in full swing, for the sway of the Great Mogul had only been extended over the northern part of the Deccan, and was as yet far away from the Peninsula. Accordingly the British traders at Madras connived at the exportation of slaves by sea. Some restraints, however, were placed upon kidnapping by insisting on the registration of every slave bought or sold in Madras, together with the names of the seller and purchaser, in order that the information might be given in the event of any inquiry by kinsfolk or acquaintance, and also that a fee might be levied on the registration of every slave. [Sidenote: Great Mogul conquers the Deccan.] In 1688 the British rulers of Madras abolished the slave trade by public proclamation. The Great Mogul, the once famous Aurangzeb, was engaged in conquering the Sultans of the Deccan. Unlike his predecessors, Aurangzeb was a bigoted Sunni, or a zealous believer in the four Caliphs who succeeded Mohammed. The Sultans of the Deccan were Shiahs who damned the first three Caliphs as usurpers, and swore that Ali, and Ali only, the son-in-law of the Prophet, the husband of Fatima and the father of Hassan and Hosein, was the rightful successor of Mohammed. Under such circumstances Aurangzeb was impelled by pious zeal for the interest of the Sunni religion to conquer and slay the heretic Sultans of the Deccan and annex their dominions to the Mogul empire. He next prepared to march his army further south into the Peninsula, with the view of conquering the Hindu Rajas and compelling their idolatrous subjects to accept the religion of the Koran. [Sidenote: Stoppage of the slave trade.] The British at Madras were greatly alarmed at the threatened approach of the Great Mogul. They were naturally afraid of sharing the fate of the Portuguese at Hughly. Accordingly they abolished the slave trade by proclamation, and sent numerous petitions to Aurangzeb, tendering their submission to the Great Mogul, praising his imperial majesty to the skies, imploring his protection as though he had been another Cyrus or Darius, and engaging to pay the old rent of 500_l._ per annum in pagodas. Matters were finally arranged, but it is grievous to add that the pious Aurangzeb was not so careful of the welfare of the Hindus as his liberal and tolerant predecessors. He preferred the laws of Mohammed to those of his Mogul ancestor, Chenghiz Khan; and within a few years the slave trade at Madras was as brisk as ever. [Sidenote: British toleration.]
