Dakshina Kosala Kingdom
Dakshina Kosala(Hindi:दक्षिण कौशल) or Southern Kosala was a colony of Kosala kings identified to be the Chhattisgarh state and Western Odisha region of India. Raghava Rama's mother " Kausalya " was from this kingdom.
In ancient Indian literature, in the “Ramayana”, “Mahabharata” and the “Puranas” one can find many references to the ancient Kosala Kingdom of northern India. Surya Vanshi Ikshvaku dynasty kings ruled Kosala with Ayodhya as their capital. “Sri Ram Chandra” was a great king of that clan, based on whose character and activities, the great epic “Ramayana” was written. In this great epic, it is mentioned that after Sri Rama, the kingdom was divided among his two sons, Lava and Kusha. North Kosala went to Lava as his share with “Shravasti Nagari”as his capital, and Kusha got south Kosala as his share. He established his new capital, “Kushasthalipura,” on the river “Kushavratee” near the “Vindhya” mountain range, which divides north and south India. This “Kushasthalipura” is identified near “Malhar” in the present-day Bilaspur district of Chhattisgarh state. South Kosal was spread across present day’s Chhattisgarh state and Western Odisha region. In the course of time, Dakshin (South) Kosal developed as a mighty empire and for various reasons, mainly because of the rise of the kingdoms of Magadha and Kashi, North Kosal became weaker and lost its existence.
Sahadeva's military campaigns
Sahadeva targeted the kingdoms in the regions south to the Gangetic Plain. Vanquishing the invincible Bhismaka, Sahadeva then defeated in battle the king of Kosala and the ruler of the territories lying on the banks of the Venwa, as well as the "Kantarakas" and the kings of the eastern Kosalas.
