Three Crowned Kings

[citation needed] The Pandyas were the earliest of the Muvendhar and were of high antiquity being mentioned by Kātyāyana and Valmiki.

[citation needed] The Roman and Greek writers praise Korkai (now called Tuticorin or Thoothukudi) as the seaport of the Pandyas.

[citation needed] The Cholas were a prominent dynasty in South India, and they played a significant role in the Sangam Age, which is generally considered to span from 300 BCE to 1297 CE.

They were known for their craftsmanship and exported exquisite bronze sculptures, pottery, and textiles, which were highly sought after in foreign markets.

The Chera kingdom, located in present-day Kerala and Kongu Nadu, had a significant impact on trade, economy, and cultural exchange during that time.

Apart from spices, the Cheras also traded in other valuable commodities such as ivory, pearls, textiles, precious stones, and forest products.

They had access to the rich resources of the Western Ghats and the forests of Kerala, enabling them to export goods like timber, teak, sandalwood, and medicinal herbs.

According to it, the Shramana king Shalivahana (also known as Bhoja in this story) defeated Vikramaditya, and started persecuting the worshipers of Shiva and Vishnu.

After failing to kill Shalivahana with a rain of fire, Shiva created three kings: Vira Cholan (Chola), Ula Cheran (Chera), and Vajranga Pandiyan (Pandya).

They then reached Cudatturiyur (possibly Uraiyur), where Vira Cholan wrote letters to all those who worshipped Shiva and Vishnu, seeking their help against Shalivahana.

Chola Purva Patayam dates Shalivahana's defeat to the year 1443 of an uncertain calendar era (possibly from the beginning of Kali Yuga).
