Sub-caste

Jāti (in Tamil:ஜாதி, Devanagari: जाति, Bengali: জাতি, Telugu:జాతి, Kannada:ಜಾತಿ, Malayalam: ജാതി, literally "birth") is a group of clans, tribes, communities and sub-communities, and religions in India. Each jāti typically has an association with a traditional job function or tribe. Religious beliefs (e.g. Sri Vaishnavism or Veera Shaivism) or linguistic groupings may define some jatis. Among the Muslims, the equivalent category is Qom or Biradri.

A person's surname typically reflects a community (jati) association: thus Gandhi = perfume seller, Dhobi = washerman, Srivastava = military scribe, etc. In any given location in India 500 or more jatis may co-exist, although the exact composition will differ from district to district.

Professor Madhav Gadgil (1983) has described Jatis as self-governing, closed communities, based on his research in rural Maharashtra:

Indian society is even today an agglomeration of numerous castes, tribes and religious communities. The tribal and caste groups are endogamous, reproductively isolated populations traditionally distributed over a restricted geographical range. The different caste populations, unlike tribes, have extensive geographical overlap and members of several castes generally constitute the complex village society. ;)

In such a village society, each caste, traditionally self regulated by a caste council, used to lead a relatively autonomous existence. Each caste used to pursue a hereditarily prescribed occupation; this was particularly true of the artisan and service castes and the pastoral and nomadic castes. The several castes were linked to each other through a traditionally determined barter of services and produce (Ghurye 1961, Karve 1961).

These caste groups retained their identity even after conversion to Islam or Christianity. Each of the caste groups was thus the unit within which cultural and perhaps genetic evolution occurred, at least for the last 1500 years when the system was fully crystallized and probably much longer. Over this period the various castes had come to exhibit striking differences in cultural traits like skills possessed, food habits, dress, language, religious observances as well as in a number of genetic traits.
