Kalinga is a historical region of India. It is generally defined as the eastern coastal region between the Mahanadi and the Godavari rivers, although its boundaries have fluctuated with the territory of its rulers. The core territory of Kalinga now encompasses a large part of Odisha and northern part of Andhra Pradesh. At its widest extent, the Kalinga region also included a part of present-day Chattisgarh and Telangana.
The Kalingas have been mentioned as a major tribe in the legendary text Mahabharata. In the 3rd century BCE, the region came under Mauryan control as a result of the Kalinga War. It was subsequently ruled by several regional dynasties whose rulers bore the title Kalingadhipati ("Lord of Kalinga"); these dynasties included Mahameghavahana, Vasishtha, Mathara, Pitrbhakta, and Eastern Ganga. At various times, the region also formed part of the bigger empires, and gradually lost its distinct political identity after the Eastern Gangas.
