Tamilakam was the name of the ancient Tamil country that included

Tamilakam refers to the ancient Tamil country that flourished during the Sangam period. Geographically, it encompassed the southernmost part of the Indian peninsula. According to ancient Tamil literature and historical records, its boundaries were defined as the land between the Tirupati hills (Vengadam) in the north and Kanyakumari (the southernmost tip) in the south [3]. This region included present-day Tamil Nadu, Kerala, and parts of Andhra Pradesh and Karnataka. While the Chola and Pandya dynasties occasionally expanded their influence or conducted maritime trade with Sri Lanka, the core definition of Tamilakam in the Sangam corpus specifically refers to the mainland territory bounded by the northern hills and the southern sea [4]. The region was home to the 'Three Crowned Kings'—the Cheras, Cholas, and Pandyas—who ruled over this stable and prosperous landscape [3].
