Thousands of copper plates and stone inscriptions have also been found within Tamilakam. Most of the inscriptions found here belong to the Chera, Chola, and Pandya rulers. These rulers used to give land grants to Brahmins. These land grants were recorded as inscriptions and kept in temples. The number of inscriptions increased as Brahmins moved from the north to the south and settled here. Not just rulers, even common people inscribed in memory of heroes who sacrificed their lives.
