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 caste system in India is an important part of ancient Hindu tradition and dates back to 1200 BCE. The term caste was first used by Portuguese travelers who came to India in the 16th century. Caste comes from the Spanish and Portuguese word casta which means race, breed, or lineage. Many Indians use the term jati.
