To corroborate this, a Tamil Brahmi inscription at Jambai (near Tirukkovilur ) mentions about the king Athiyaman Neduman Anchi as Sathiya Puto Atiyan Neduman Anjihi Itta Pali. Malaiyaman Tirumudikkari was the illustrious ruler of this dynasty. The Sangam works speak of the invasion of Tirukkoilur and defeat of Malayaman Tirumudikkari by Neduman Anji, king of Takadur (modern Dharmapuri) who is said to have offered Avvaiyar, the celebrated poetess (of that period), a myrobalan (gooseberry) fruit to increase her longevity.
It also has an important place in Tamil history.Its the Birth place of Raja Raja Chola I.The great King under whom The Cholas were at the height of their power continuously from the later half of the 9th century until the beginning of the 13th centuries. Under Rajaraja Chola I and his son Rajendra Chola I, the dynasty became a military, economic and cultural power in Asia and the chola navy had checked the Oceans of South-East asia for sometime.
Tirukkoilur Malaiyaman's daughter Vanavanmahadevi, a princess from the clan of Malaiyaman was married to Parantaka Chola II.who's second son Arunmozhi varman famously called as Rajaraja Cholan (Ponnien selvan/Peruvudaiyar/also called as Raja Kesari Varman.. Raja Raja Devar).
He was one of the greatest emperors of the Tamil Chola Empire of India who ruled between 985 and 1014 CE. He established the Chola empire by conquering the kingdoms of southern India expanding the Chola Empire as far as Sri Lanka in the south, and Kalinga (Orissa) in the northeast. He fought many battles with the Chalukyas in the north and the Pandyas in the south. By conquering Vengi, Rajaraja laid the foundations for the Later Chola dynasty. He invaded Sri Lanka and started a century-long Chola occupation of the island.
He streamlined the administrative system with the division of the country into various districts and by standardizing revenue collection through systematic land surveys. Being an ardent devotee of Lord Shiva, he built the magnificent Peruvudaiyar Temple (also known as the Brihadeeswarar Temple) in Thanjavur and through it enabled wealth distribution amongst his subjects. His successes enabled his son Rajendra Chola I to extend the empire even further.
