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.
Historians later called this the caste system. Caste members lived, ate, married, and worked with their own group. A person born into one caste rarely changed castes or mixed with members of other castes. Social rules defined how to behave within a caste and when in the presence people from other castes.
