Toṇḍaimaṇḍalam, also known as Toṇḍai Nāḍu, is a historical region located in the northernmost part of Tamil Nadu and southernmost part of Andhra Pradesh.[1] The region comprises the districts which formed a part of the legendary kingdom of Athondai Chakravarti. The boundaries of Tondaimandalam are ambiguous – between the river basins of Penna River and Ponnaiyar River. During the reign of Rajaraja I, this region was called as Jayankonda Cholamandalam.[2]
