comprising Kalahandi, undivided Koraput and Bastar region. Asurgarh was capital of Mahakantara. After Vyaghraraja, the Nala kings like Bhavadatta Varman, Arthapati and Skanda Varman ruled over south part of this region up to about 500, the territory was known as Nalavadi-visaya and rest of Mahakantara, lower part of Tel river valley was ruled by king Tastikara and his scions, the kingdom was known as Parvatad-waraka, whose headquarters was Talabhamraka near Belkhandi. In the 6th century a new kingdom developed in the Kalahandi tract under King Tustikara, but very little is known about other kings of his family. Maraguda valley was identified as capital of Sarabapuriyas. During Sarabapuriyas in the 6th century, Kalahandi lost its political entities and merged with eastern part of South Kosal or Kosal. But this was also for a short period as in succeeding phase it assumed a distinct name Trikalinga. By the 9th–10th centuries the region including Western Odisha, Kalahandi, Koraput and Bastar was known as Trikalinga. The Somavamsi king Mahabhavagupta I Janmejaya (925 – 960) assumed the title Trikalingadhipati. Trikalinga was short lived and Chindakangas carved out a new kingdom called Chakrakota Mandala or Bramarakota Mandala, which later one expanded to whole Kalahandi and Koraput. Naga dynasty of Kalahandi The Naga dynasty started ruling Kalahandi in 1006. The Nagas of Kalahandi are the only dynasty in Odisha having a record of thousand years (1050–1948). During the 12th century Chkrakota Mandal was incorporated with the Ganga realm of Kalinga, and renamed "Kamala Mandala", thus Kalahandi region became part of Kalinga as a feudatory of the Eastern Gangas under Nagas rules and continued till the 14th century. After 14th century Nagas owed allegiance from Eastern Gangas to the Suryavamsi Gajapatis. This territory assumed independence after the downfall of the Gajapatis of Odisha in 1568. According to tradition the Kalahandi kingdom commanded sovereign power over eighteen garbs. It was occupied by the Bhonslas of Nagpur in the middle of the 18th century but still it was a Gadajat under Nagas rule. In 1853 the Nagpur state lapsed to the British Crown as Raghujee III died without an heir. Then Kalahandi became a princely state under British and known as Karonda Mandal. Maharaja Pratap Keshari Deo, the Ex-Maharaja of Kalahandi, in one of his articles expressed his view that the historical significance of naming Kalahandi as Karunda Mandala is based on the availability of Corundum in this region.
