India's caste system is different from the Aryan social class because the Indian's marriages were only permitted only between persons of the same class.
About 1500 B.C., groups of warlike people left their homes in central Asia, possibly near the Caucasus Mountains, and came to India. These people called themselves arya (kinsmen or nobles). They are now known as the Aryans. The Aryans are said to have entered India through the fabled Khyber pass, around 1500 BC. They intermingled with the local populace, and assimilated themselves into the social framework.
