Vaigai River in Madurai
Mauryan emperor Asoka (3rd century BCE) seems to have been on friendly terms with the people of south India and Sri Lanka (the Cholas, the Pandyas, the Satiya Putras, the Kerala Putras and the Tamraparnis). There are no indications that Asoka tried to conquer the extreme south India (the Tamilakam – the Abode of the Tamils).

The three chiefly lines of the early historic south India – the Cheras, Pandyas and Cholas – were known as the mu-vendar (“the three vendars”). They traditionally based at their original headquarters in the interior Tamil Nadu (Karur, Madurai and Uraiyur respectively). The powerful chiefdoms of the three ventar dominated the political and economic life of early historic south India. The frequent conflicts between the Chera, the Chola and the Pandyas are well documented in ancient (the Sangam) Tamil poetry. The Cheras, Cholas and Pandyas also controlled the ports of Muziris (Muchiri), Korkai and Kaveri respectively (for the trade with the Graeco-Roman world).The gradual shift from chiefdoms to kingdoms seems to have occurred in the following period.

The famous inscription of king Kharavela at Hathigumpha (mid-first century BCE) mentions the defeat of a confederacy of the “Tramira” countries which had been a threat to Kalinga. It also remembers the precious pearls brought to the capital as booty from the “Pandya” realm. The Pandyas chiefdom was famous for its pearl fisheries and silk industry. Korkai and Alagankulam are believed to have been the exchange centres of the Pandyas. Korkai, a port at the mouth of the river Tambraparni, was linked to the famous pearl fisheries and Alagankulam was also developed as a port.

A number of coins attributed to early historic Pandyas are found from the region.Inscriptions, datable to c. 2nd century BCE, recording royal grants – both from royals and wealthy commoners – were also discovered from the Pandyas country.

The Pandyas seems to be the most prominent of the three “ventar” rulers. There are even references to a Pandya queen from 3rd century BCE representing a confederacy of the Tamil countries. Madurai, in south Tamil Nadu, was the most important cultural centre in south India as the core of the Tamil speakers. Megalithic relics such as menhirs, dolmens, urn burials, stone circles and rock-cut chambers/passages can be found in south India. Burial goods include iron objects, ivory ornaments, Black-and-Red Ware and even some Roman Imperial coins. The so-called “velir” hill chieftains are assumed to be associated with these megalithic burials.

Greek and Latin accounts (early centuries CE), coins with legends in Tamil-Brahmi script, and Tamil-Brahmi inscriptions suggest the continuity of the Pandyas dynasty from the 3rd century BCE to early centuries CE. The early Pandyas, along with the Cheras and the Cholas, were eventually displaced by the Kalabhra dynasty.

The Pandya kingdom was revived by king Kadungon (r. 590–620 CE) towards the end of the 6th century CE. In the Velvikudi inscription, a later copper-plate, Kadungon appears as the “destroyer” of the “anti-Brahmanical” Kalabhra kings. With the decline of the Kalabhra dynasty, the Pandyas grew steadily in power and territory. With the Cholas in obscurity in Uraiyur, the Tamil country was divided between the Pallavas of Kanchi and the Pandyas of Madurai.

From 6th century to 9th century CE, the Chalukyas of Badami, the Pallavas of Kanchi, and Pandyas of Madurai dominated the politics of south India. The Badami Chalukyas were eventually replaced by the Rashtrakutas in the Deccan. The Pandyas took on the growing Pallava ambitions in south India, and from time to time they also joined in alliances with the kingdoms of the Deccan Plateau (such as with the Gangas of Talakad in late 8th century CE). In the middle of the 9th century, the Pandyas had managed to advance as far as Kumbakonam (north-east of Tanjore on the Kollidam river).

Sendan (r. 654–70 CE), the third king of the Pandyas of Madurai, is known for expanding his kingdom to the Chera country (western Tamil Nadu and central Kerala). Arikesari Maravarman (r. 670–700 CE), the fourth Pandya ruler, is known for his battles against the Pallavas of Kanchi. Pallava king Narasimhavarman I (r. 630–668 CE), the famous conqueror of Badami, claimed to have defeated the Pandyas. Chalukya king Paramesvaravarman I “Vikramaditya” (r. 670–700 CE) is known to have fought battles with the Pallavas, the Gangas, and probably with the Pandyas too, on the Kaveri basin.[16]

Kirtivarman II (r. 744/5–55 CE), the last Chalukya king, managed to lose to his southern countries as a result of his battles with the Pandyas. Pandya kings Maravarman Rajasimha I (r. 730–65 CE) and Nedunjadaiyan/Varagunavarman I (r. 765–815 CE) threatened Pallava king Nandivarman II Pallavamalla (r. 731–96 CE) who had managed to defeat the Gangas in c. 760 CE. Varagunavarman I invaded the Pallava country, conquered the Kongu country (western Tamil Nadu) and Venadu (south Kerala). King Srimara Srivallabha (r. 815–62 CE) sailed to Sri Lanka, subjugated king Sena I, and sacked his capital Anuradhapura (the Panya invasion of Sri Lanka followed a period of vassalage). However, Srimara Srivallabha was soon overpowerd by Pallava king Nripatunga (r. 859–99 CE). Sena II, the king of Sri Lanka, invaded the Pandya country, sacked Madurai and chose Varagunavarman II (r. c. 862–880 CE) as the new king soon after. It is proposed that the start of the Kollam Era, the Kerala calendar, in 825 CE marked the liberation of Venadu from Pandya control.

During the rule of Dantivarman (r. 796–847 CE), the Pallava territory was reduced by the encroachment from the Pandyas from the south (and Rashtrakutas and the Telugu-Cholas from north). Pallava king Nandivarman III (r. 846–69 CE) was able to defeat the Pandyas and Telugu-Cholas (and even the Rashtrakutas) with the help of the Gangas and the emerging Cholas.
