The origin and identity of the Kalabhras is uncertain. Information about the origin and reign of the Kalabhras is uncertain and scarce. One theory states that they were probably
hill tribes that rose out of obscurity to become a power in
South India. Historical documents of the
Vettuva Gounder community interpreted by the
Kongu historian Pon Dheepankar show that the
Karkathars,
Vanniars and
Maravars (other than the Kondayankottai caste),
Kallars, who were a formerly a
denotified tribe of Tamil Nadu were the Kalabhras. Other theories state that they were
Karnatas probably from north of Tamil-speaking region (modern southeast Karnataka), According to Kulke and Rothermund, "nothing is known about the origins or tribal affiliations" of the Kalabhras, and their rule is called the "Kalabhra Interregnum". However, the textual support for these conjectures is unclear. In support of their possible Jaina patronage, is the 10th-century Jain text on grammar which quotes a poem that some scholars attribute to Acchuta Vikkanta, a Kalabhra king. According to
Karl Potter in
Encyclopedia of Indian Philosophies: Buddhist philosophy from 360 to 650 AD, multiple scholars place the 5th-century Buddhadatta in the Chola kingdom near Kaveri river. According to Arunachalam, the Pali manuscripts of this text includes the name Acutavikkante Kalambakulanandane and therefore he states Acutavikkante must have been a Kalabhra king. However, the oldest surviving
Vinayaviniccaya manuscript in Pali does not have that name, it has Kalabbha. This could be Kalabhra. Buddhadatta in his manuals (in the
Nigamanagātha of
Vinayavinicchaya, verse 3179) identifies his patron as follows: Accut' Accutavikkante Kalambakulanandane mahin samanusāsante āraddho ca samāpito. In the time of the immortal Accutavikkante, the pride of the Kalamba family this work was accomplished. and once again the tika (colophon) adds: Kalambhakulavamsa jāte Accutavikkamanāme Colarājini Colarattham samanusāsante ayam vinicchayo mayā āraddho ceva samāpito cāti This work Vinicchaya was accomplished, when the king of Cholas, Accutavikkaman, born in the lineage of the Kalamba family was ruling the earth. Amritasagara, a
Jain poet of the 10th century CE and the author of the works Yapparungalam and Yapparungalakkarikai, has also written a few verses about Achyuta Vikranta. A few verses of the
Tamil Navalar Caritai, a later work, is sometimes identified as glorifying Accuta Vikranta. It describes the three kings
Chera,
Chola and
Pandya paying obeisance to king Accuta when they were taken captive. 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 (Jainism and Buddhism). In contrast, R.S. Sharma states the opposite theory and considers "Kalabhras as an example for peasant revolt to the state" - with tribal elements, albeit around the 6th century. All these theories are hampered by the fact that there is a "profound lack of evidence for the events or nature of Kalabhra rule", states Rebecca Darley.
In epigraphs Pulankurichi inscription The earliest Kalabhra inscription available is the Pulankurichi (Tamil Nadu) epigraph of king Chēndan Kurran (Kootran) dated to 270 CE. It is also one of the earliest inscriptions in Tamil and extends to over 15 metres in length. It refers to the administrative divisions of the kingdom and also to Vedic sacrifices and temples. Scholar
Kamil Zvelebil indicates that the language of the inscription is almost identical to classical Tamil similar to the one used in the
Tolkappiyam and
Sangam texts.
8th-century Velvikudi grant inscription A much-cited and discussed epigraphical evidence for the existence of Kalabhras is the 155-lines-long 8th-century
Velvikudi grant copper plate inscription of Nedunjadaiyan. {{Blockquote| L 39: Then a Kali king named Kalabhran took possession of the extensive earth driving away numberless great kings (adhiraja) and resumed the (village mentioned Velvikudi) above. 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. The inscription then recites the generations of Pandya and Chola kings who followed the victorious Kadungon, and finally to king Nedunjadaiyan who ruled in the year of the inscription (c. 770 CE). The copper plate records that a Brahmin complainant said that the land grant which was given to his ancestors before Kalabhras "ignobly seized it" has not been returned so far after numerous generations (lines 103-118). Some scholars dismiss the Kalabhra interregnum as for all practical purposes "a myth". K. R. Venkatarama Iyer suggests that the Kalabhras might have emerged from the
Bangalore-
Chittoor region early in the 5th century. Other scholars are skeptical of the coin's dating and interpretation, the origins of the coins and the impact of trade, and the rareness of Jain and Buddhist iconography. According to Timothy Power - a scholar of Middle East and Mediterranean archaeology and history, coins and texts attest to an on-going trade between the Mediterranean, Middle East and South Indian ports such as
Muziris until the 5th century, but then suddenly there is no mention of Indian ports in the Mediterranean texts around mid-6th century. == Religion and literature ==
