"From the day India became a target of Muslim invaders its people began to be enslaved in droves to be sold in foreign lands or employed in various capacities on menial and not-so-menial jobs within the country. To understand this phenomenon it is necessary to go into the origins and development of the Islamic system of slavery. For, wherever the Muslims went, mostly as conquerors but also as traders, there developed a system of slavery peculiar to the clime, terrain and populace of the place."
