The caste system in India served as a mechanism of organization.
 Brahmins then began to practise endogamy and enclosed themselves, hence Ambedkar defines caste as "enclosed class"
 This characteristic of caste was missing from large parts of India, stated Ghurye, and in these regions all four castes (Brahmins, Kshatriyas, Vaishyas and Shudras) did agriculture labour or became warriors in large numbers
