According to one long-held theory about the origins of South Asia's caste system, Aryans from central Asia invaded South Asia and introduced the caste system as a means of controlling the local populations. The Aryans defined key roles in society, then assigned groups of people to them.
The original caste system is a division of people into four essential groups, the spiritually inclined people (Brahmins), the security personnel (Kshatriyas), the producers of the means of livelihood (Visayas) and the instruction followers (Sudras).everal characteristics distinguish a caste system. The first is the tendency toward endogamy, meaning that people marry within the same caste exclusively. Caste mobility is also extremely rare; one cannot transform from a laborer to a scholar except in very rare circumstances, for example.
