| Hinduism recognises four varnas based on occupation and ancestry. |
| Vedic civilization is based on four varnas, but there are people who do not fit within these four. |
| Traditionally, there were four main varnas, plus one group of outsiders. |
| Strictly speaking, class and caste are different social institutions, though castes are often assumed to fit into the four varnas. |
| The four distinct Varnas or castes that are mutually exclusive, hereditary, endogamous, and occupation-specific are the Brahmins, Kshatriyas, Vaisyas, and Sudras. |
| It became increasingly agricultural and was socially organised around the hierarchy of the four varnas, or social classes. |
