Jatis were the sub-castes which were grouped on the basis of economic and social status. They were ranked as per their backgrounds and their occupations. Ranks were not fixed permanently. ... This assembly of elders was called jati panchayat. But jatis were also required to abide by the rules of their villages. Jati, also spelled jat, caste, in Hindu society. The term is derived from the Sanskrit jāta, “born” or “brought into existence,” and indicates a form of existence determined by birth. In Indian philosophy, jati (genus) describes any group of things that have generic characteristics in common. In addition, caste has allowed countless groups that have migrated into India to find a place and to play an important role.
