[11] Historian Upinder Singh states that Shivaskandavarman rise in the 4th century, as evidenced by inscriptions, show Kalabhras were not in power at that time near rivers Penner and Vellar (close to Kaveri).[13] Historical documents of the Vettuva Gounder community interpreted by the Kongu historian Pon Dheepankar show that the Piramalai Kallars,[14] who were a formerly a local tribe of Tamil Nadu were the Kalabhras.[15] of the Other theories state that they were Karnatas probably from north of Tamil-speaking region (modern southeast Karnataka),[9][10] or on etymological grounds may have been the Kalappalars of Karkarthar community or the Kalavar chieftains.and once again the tika (colophon) adds:[24][25] Kalambhakulavamsa jāte Accutavikkamanāme Colarājini Colarattham samanusāsante ayam vinicchayo mayā āraddho ceva samāpito cāti This work Vinicchaya was accomplised, when the king of Cholas, Accutavikkaman, born in the lineage of the Kalamba family was ruling the earth.[28][29] According to Burton Stein, the Kalabhra interregnum may represent a strong bid by non-peasant (tribal) warriors for power over the fertile plains of Tamil region with support from the heterodox Indian religious tradition (Buddhism and Jainism).[30] This may have led to persecution of the peasants and urban elites of the Brahmanical religious traditions (Hinduism), who then worked to remove the Kalabhras and retaliated against their persecutors after returning to power.L 40: After that, like the sun rising from the expansive ocean, the Pandyadhiraja named Kadungon, the lord of the South of sharp javelin who wore (the cloak of) dignity and was the leader of an army, sprang forth, occupied (the throne), spreading around him the brilliant splendour of (his) expanding rays (prowess), destroyed the kings of the extensive earth surrounded by the sea together with (their) strongholds and (their) fame, wielded the sceptre of justice and removed by his strength the evil destiny of the goddess of the earth whose splendour deserved to be under the shade of (his) white umbrella, by terminating by his strength the possession of her under others and establishing her in his own possession in the approved manner and destroyed the shining cities of kings who would not submit to him.[34] This inscription has been assumed to be an accurate historical record by some scholars, interpreted to affirm that Kalabhras existed for some period, they conquered some or all parts of the Pandyan kingdom, they seized lands belonging to Brahmin(s) and were defeated by the Pandyas (Pāṇṭiya).In "rare specimens", states Gupta, one finds an image of a seated Jain muni (monk) or the Buddhist Manjushri, or a short sword or the Swastika symbol.More particularly, states Peterson, the Kalabhras may have supported the Digambara sect of Jainism and that they "supposedly" suppressed the Vedic-Hinduism religion that were well established in the Tamil regions by the 3rd century CE.[42] In the Nigamanagātha of Vinayavinicchaya, Buddhatta describes how he wrote the work while staying at the monastery built by one Venhudassa (Vishnudasa) on the banks of the Kaveri in a town called Bhootamangalam.[47][full citation needed] According to the Gandhipadavannanā of Buddhadatta's manual Vinayavinicchaya, the word Accuta of the patron king was used in the same context as the epithet of Narayana (Accutassa Nārāyanassa viya vikkantām ettassāti Accutavikkanto).[7] This is attested by the numerous inscriptions dated from the 6th century and thereafter, as well as the Chinese language memoirs of the Buddhist pilgrim Xuanzang who visited the Tamil region about 640 CE along with other parts of the Indian subcontinent.[55] Xuanzang describes a peaceful cosmopolitan region where some 100 monasteries with 10,000 monks were studying Mahayana Buddhism, Kanchipuram was hosting learned debates with hundreds of heretic Deva (Hindu) temples but no Buddhist institutions.
