Slavery in India was an established institution in ancient India by the start of the common era, or likely earlier.[1] However, its study in ancient times is problematic and contested because it depends on the translations of terms such as dasa and dasyu.[1][2]
Slavery in India escalated during the Muslim domination of northern India after the 11th-century, after Muslim rulers re-introduced slavery to the Indian subcontinent.[1] It became a predominant social institution with the enslavement of non-Muslims, along with the use of slaves in armies for conquest, long since a vital tradition in all Muslim kingdoms.[3][4] According to Muslim historians of the Delhi Sultanate and the Mughal Empire era, after the invasions of non-Muslim kingdoms, Indians were taken slaves with many exported to Central Asia and West Asia.[5][6] Many slaves from the Horn of Africa were also imported into the Indian subcontinent to serve in the households of the powerful or the Muslim armies of the Deccan Sultanates and the Mughal Empire.[7][8][9]
