has led Cynthia Talbot, a professor of History and Asian Studies, to question whether varna was socially significant in the daily lives of this region. Most mentions of varna in the Andhra inscriptions come from Brahmins. Two rare temple donor records from warrior families of the 14th century claim to be Shudras. One states that Shudras are the bravest, the other states that Shudras are the purest. Richard Eaton, a professor of History, writes, "anyone could become warrior regardless of social origins, nor do the jati—another pillar of alleged traditional Indian society—appear as features of people's identity. Occupations were fluid." Evidence shows, according to Eaton, that Shudras were part of the nobility, and many "father and sons had different professions, suggesting that social status was earned, not inherited" in the Hindu Kakatiya population in the Deccan region between the 11th and 14th centuries. In the Tamil Nadu region of India, studied by Leslie Orr, a professor of Religion, "Chola period inscriptions challenge our ideas about the structuring of (south Indian) society in general. In contrast to what Brahmanical legal texts may lead us to expect, we do not find that caste is the organising principle of society or that boundaries between different social groups is sharply demarcated." In Tamil Nadu, during ancient and medieval period, the Vellalar were the elite caste and major patrons of literature. For northern Indian region, Susan Bayly writes, "until well into the colonial period, much of the subcontinent was still populated by people for whom the formal distinctions of caste were of only limited importance; even in parts of the so-called Hindu heartland of Gangetic upper India, the institutions and beliefs which are now often described as the elements of traditional caste were only just taking shape as recently as the early eighteenth century—that is, when the Mughal era was collapsing and western power was expanding into the subcontinent." For western India, Dirk H. A. Kolff suggests open status social groups dominated Rajput history during the medieval period. He states, "The omnipresence of cognatic kinship and caste in North India is a relatively new phenomenon that only became dominant in the early Mughal and British periods respectively. Historically speaking, the alliance and the open status group, whether war band or religious sect, dominated medieval and early modern Indian history in a way descent and caste did not."
