Valluvars are believed to have been the priests of the Pallava kings before the introduction of Brahmins and for sometime after their arrival.^[1] The exalted position of Valluvars in the social hierarchy during those times is indicated by inscriptions which refer to Valluvars in a respectful manner.^[6] Moreover, the Tamil saint Thiruvalluvar is believed to have been a member of this community^[7] and there is a subsect of Valluvars claiming descent from him.^[6][3][4]

Though Valluvars were regarded as a subgroup of the Paraiyar community by caste Hindus, Thurston mentions that Valluvars did not eat with Paraiyars.^[8] Valluvar houses were generally located at a significant distance away from the parcheri where they lived.^[8] Owing to their occupation as priests, all males over twelve wore the sacred thread.^[8] The Valluvars were also noted for their abstinence from beef.^[8]

The Valluvars are also called Pandaram or Valluva Pandaram.^[8] The priests of the Valluvars are sometimes called Vellala Pandaram, Thiruvalluva Nayanar.^[8]

Valluvars were an untouchable caste.^[9][10]

The important sub-sects of Valluvans are Paraiyan, Tavidadari and Tiruvalluvan.^[11] Valluvars are broadly classified into two main sub-divisions: Arupadhu Katchi or sixty clans and Narpadhu Katchi or forty clans ^[11]

The Arupadhu Katchi considered themselves the descendants of Nandi Gurukkal and have his name as their gotra.^[11] The Narpadhu Katchi are of the gotra Sidambara Sayichya Ayyamgar.^[12] The sub-division alvar claim descent from Tiruppan Alvar.^[12]

Valluvars follow both Saivism and Vaishnavism. Saivite and Vaishnavite Valluvars dine together, but not intermarry.^[6] A particular class of Valluvars officiated as priest at Paraiyar funerals.^[6] This particular class of Valluvars was known as Paraiya Tadas and were regarded as inferior by other sections of Valluvars.^[6] Another section of Valluvars wear a necklace of tulsi beads and are known as Alvar Dasari or Tavadadhari.^[6] Some hold that the true Valluvan is one who practices astrology and that those who officiate as priests aren't true Valluvars.^[11] The affairs of the community are handled by a caste-council.^[12] The community is headed by a Kolkaran or a Kanakkan.^[12] There are the hereditary astrologers of the Indian temple town of Vaithiswaran Koil and are considered experts in Nadi astrology.^[13][14]

The Valluvars generally officiate in Paraiyar marriages^[14] and funerals. During such occasions, Valluvar priests used to chant Sanskrit shlokas.^[14]
