Vikirama Aditha Pandya was rewarded by the Portuguese for his actions of 1532, when as part of the arrangement for protection he had offered to manage the pearl diving on behalf of the Portuguese. He became known as Senhor dos Senhores "("first among notables")" Dom João da Cruz (but see Note 1) and was recognised as headman and official intermediary by the Portuguese from 1543 until 1553. (1543 was the year that the Portuguese first settled in Tuticorin, and the point from which that port began to expand until it eventually became the hub of the pearl fishery). His title of "jati thalavan" (head of the caste) was passed down through 21 other members of his family. Caste elders in the various villages were also among the early beneficiaries of Portuguese recognition, perhaps because they were the first to be converted. The consequence was that a formal system of hierarchical control, based on religious authority and economic standing and extending from the "jati thalavan" through to the elders and then to the villagers, became established in the eyes of Paravars and non-Paravars alike. It remained in existence until the 1920s, with the elders extracting payments from villagers which were then passed on to the "jati thalavan", and the latter in return managing affairs (including the fishery operations) and adjudicating in both internal and external disputes involving the community. Kaufmann has commented that these "highly organised caste institutions" including hereditary headmen and councils of elders holding sway, was a rare thing in the agrarian economy of southern India and both lasted longer and was more elaborate than most equivalent Hindu systems of the area. Another writer has said that " ... by the beginning of the eighteenth century the Tamil Paravas had emerged as one of south India's most highly organised specialist caste groups", and adds that the hierarchical system had its origins in times prior to the Portuguese intervention.
