Ezhimala, Pazhayangadi, and several villages and towns in this region find plenty of mention in the extant Tamil Sangam Period's literature (500 BC to 300 AD). Pazhayangadi is the present corrupted form of its ancient name of Pazhi. Pazhi is mentioned as the ancient capital of King "Udayan Venmon Nannan" (known as "Nannan" or "Nandan") of the Mushika or Kolathiri Royal Family. Though the Dynasty of "Nannan"s was a cousin or sister dynasty of the Cheras and Pandyas and Cholas, warfare among them was nearly consistent, and the period of "Nannan" was no exception. There are texts that speak of "Nannan" fighting heroic battles at Pazhi against the Chera Kings who invaded his kingdom (Kolathunadu). Eventually, "Nannan" was killed in battle by the Chera king, "Narmudi Cheral". Like the other kings of the then Tamilakam cultural polity, "Narmudi Cheral" was a great patron of scholars and poets, and he once gifted his court-poet, "Kappiyattu Kappiyanar" with 40 lakhs gold coins, as a token of his poetic genius.
