"The continued dynamism of successive Islamic societies produced fresh bouts of conquest that led to new sources of slaves. Thus, on the eastern end of the Islamic world, Mahmud of Ghazni, south-west of Kabul (r.971–1030), whose empire stretched from the River Oxus to the River Indus, launched numerous raids into northern India from the 990s, annexing the Hindu state of Sahi to the east by 1021. Religious factors played a role in his attacks, which in 1022 extended far down the Ganges valley and in 1026 into Gujarat. Chroniclers claimed that his campaign of 1024 yielded over 100,000 slaves. Such numbers fed a major slave trade into Central Asia, Persia and Iraq, as well as bringing wealth to the army. The Delhi sultanate (1206–1526), established by Qutb-ud-din Aybak, who had been a military slave of the Churid Sultan Muizz u-Din, so that it is sometimes referred to as the Slave Dynasty, in turn, used Turkic slave soldiers from Central Asia as well as local Hindu soldiers. This sultanate took part in largescale slave raiding in India.... The island of Bali in the East Indies (Indonesia) was a source of Hindu slaves for the Muslim world... The campaigns in India of the Mughals and the Deccan sultanates produced many Hindu slaves, some of whom were sold on to Central Asia and Persia... In India, the Mughals enslaved rebels and those deemed rebels, for example, Hindus who rejected attempts at proselytism, as at Benares in 1632. Those captured in Mughal campaigns were often given to the troops for their use or for them to sell. Enslavement was also the fate of peasants who could not meet their taxes and rents, with men, women and children often sold to Muslim lords as a consequence. Further south in India, enslavement was used by the Deccan sultanates, notably Bijapur and Golconda, in suppressing opposition. These major Muslim states campaigned extensively into southern India and enslaved Buddhists, Hindus and others. Thus, in the 1640s, Golconda seized much of the state of Vijayahagara and Bijapur that of Mysore. However, the Mughal conquest of the Deccan sultanates of Bijapur and Golconda in the 1680s led to the end of military slavery there... India was also a source of slaves, for example with girls taken to Afghanistan and the Middle East and, from the mid-seventeenth century, forced labour moved to plantations in the Dutch-ruled coastlands of Sri Lanka."
