Kalabhra dynasty

The Kalabhra dynasty (also called Kaḷabrar, Kaḷappirar, Kallupura or Kalvar) were rulers of all or parts of Tamil region sometime between the 3rd century and 6th century CE, after the ancient dynasties of the early Cholas, the early Pandyas and Chera. Information about the origin and reign of the Kalabhras is uncertain and scarce. It is believed that they were once the feudatories of the Pallavas. Prof. M. S. Ramaswami Aiyangar, in his 1922 book "Studies in South Indian Jainism" asserted that the Kalabhra period was 'The Augustan age of Tamil literature". He also noted that many Pallava and Pandya records describe how the Kalabhras defeated the Cholas, Pandyas, and Cheras and established their rule. The Kalabhra era is sometimes referred to as the "dark period" of Tamil history, and information about it is generally inferred from any mentions in the literature and inscriptions that are dated many centuries after their era ended.

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). The Kalabhras dynasty had ended for certain by the last quarter of 6th century when Pallava Simhavishnu consolidated his rule up to the Kaveri river, south of which the Pandyas led by Kadunkon consolidated their power. Cholas became subordinates of Pallavas and they were already ruling Telugu region of Rayalaseema.

Some early scholars, including M. S. Venkatasamy and S. K. Aiyangar, suggested that the Mutharaiyars might have had links to the Kalabhra period, but this view remains speculative and is not supported by inscriptional or archaeological evidence. Later studies of Pudukkottai inscriptions recording clearly Tamil personal names such as Maran, Meenavan and Tennavan - indicate that the Mutharaiyars were a Tamil-origin group, and therefore the Kalabhra-Mutharaiyar ancestral connection is not considered an established historical conclusion.
