Velirs were a royal house of minor dynastic kings and aristocratic chieftains in Tamilakkam in the early historic period of South India.Extolled in Sangam literature for their charity and truthfulness, they were the ancestors and head of the modern Tamil Vellalarcaste. However, the Journal of Kerala Studies states that etymological interpretations that connect Vellalar with Velir are unconvincing. It suggests that the word Vellalar comes from the root Vellam for flood, which gave rise to various rights of land; and it is because of the acquisition of land rights that the Vellalar got their name. However, they are still considered to be the actual descendants of the Velir - "But this does not mean the Vellālars may not be the descendants of the Vēlir; probably they are; but the words Veļļālar, Vēļāņmai, Vēļālar, are derived from their art of irrigation and cultivation rather than from their original chieftainship. Vassals of the three main Tamil dynasties of Tamilakam (Damirica) — Chola, Cheraand Pandya, the Velirs had close relations with them through marriages and coronation right. The velirs were crowned with the epithet Satyaputo(members of the fraternity of truth) for their virtues, and their lands were often hill/mountainous terrain.
There were twelve to thirteen Velir dynastic families of fame in the Sangam age. Seven kings from seven dynastic clans of the Velir royal house formed the Kadai Ezhu Vallal (The last of the 7 (lines) of Great Patrons), liberal patrons of arts and literature in ancient Tamilakam. The word Velirbecame a title inherited by Vellalar chiefs of the medieval period.
The Kongu Velir dynasty ruled Kongu Nadu, while the Vēl Pāri dynasty produced numerous kings ruling Parambu Nadu, the most popular of whom was a close friend of the poet Kapilar. The Irunkōvēl line ruled over Ko Nadu and their most famous ruler, Pulikadimal, was a contemporary ofKarikala Chola and Kapilar. The most heralded of the Āviyar line was Vaiyāvik Kōpperum Pēkan, a contemporary of the poet Paranar, and renowned for his generosity. The Malayaman Velir dynasty ruled Nadu Naadu around Tirukkoyilur, their royal emblem featured a horse and their most famous king was Malaiyamān Thirumudi Kāri. Both he and his son Thaervann Malaiyan assisted the early Cholas and Cheras. The most famous Velir dynasty was the Athiyamān dynasty, and this dynasty's powerful and most famous king was Athiyamān Nedumān Añci. His son Elini ruled Kudiramalai of the ancient Jaffna kingdom and Vanni, a co-ruling contemporary of the famous king Korran. These kings belonged to a prolific Tamil horseman tribe. The ancient Tamil Naka Oviyar tribe of the Velir house, whose nation stretched to the Tamil emporiums of Mantai and Kudiramalai, had the famous king Nalliyakkotan who ruled this region and is paid tribute to in the Ciṟupāṇāṟṟuppaṭai.
Each of the Velir dynasties ruled from their own capitals and utilized the seaport of Arikamedu.
According to Tamil mythical tradition, the Velirs came to south from the city of Dwarka in north India under the leadership of the Vedic sage Agastya just after the collapse of the Indus Valley Civilization and belonged to the Yadava Kshatriya clan. However, some Tamil researchers say that Agastya mentioned in Vedas and Agathiyar mentioned in Tamil texts are two different characters. In Tamil language the term 'Agam' means inside and 'iyar' means belong. One who belong inside (soul) is the Tamil meaning for Agathiyar. The Velirs of Kongu Nadu were called Kongu Velirs and they ruled the Kongu region.Numerous poems in the ancient Sangam literature extol these chieftains' charity and truthfulness. Among the most prominent were those known as the 'seven patrons' (kadaiyezhu vallal); Paari, Malayaman Kaari, Ori, Adigaman, Avi, Nalli and Veliyan. Athiyamān Nedumān Añci and his son Ezhini, wereAdigaman chieftains, based in Tagadur. They were contemporaries of Auvaiyar. The Sangam poem "Thagadur yathirai", now lost, was written about his battle with the Chera king. Another Velir was Irunkōvēl (Purananur-201 by Paranar) who ruled from Koval (modern day Tirukovilur) on the banks of Pennai, (the present Ponnaiyar River) which presently discharges into the sea at Cuddalore, a town 20 miles south of Pondicherry (ancient Arikamedu).It is likely that the course of the river has changed to south over many centuries. Other Velir chiefs of repute include Alumbil Vel, Alandur Vel and Nangur Vel In Sangam literature the more prevalent word used is Vel, such as in the names Vel Avi and Vel Paari.
History
Asoka's edicts mentioned a clan of rulers called Satyaputas along with three crowned Tamil kings Sathiyaputo as mentioned in the Asokan Girnar edict is the same as Sathiyaputo mentioned in the Jambai inscription. The Jambai inscription was issued by Adigaman Chieftain. The Sanskrit name means "members of the fraternity of truth".A Tamil epigraph found recently at Jambai near Tirukkovilur in Tamil Nadu says satiyaputo atiyan netuman anci itta pali which translates to "Monastery given by Satyaputa Athiyan Nduman Anji"<9.^ Mahadevan, Iravatham (2003).
