Kalinga is mentioned in the ancient scriptures as Kalinga the Braves (Kalinga Sahasikha). During the 3rd century B.C. the Greek ambassador Megasthenes in his tour of India had mentioned about the military strength of the Kalinga army of about one lakh which consisted of 60 thousand soldiers, 1700 horses and thousands of elephants. Kalinga was also powerful in the naval force. The vast military strength of Kalinga was the cause of jealousy for the Magadha empire. According to the historians the Magadha Emperor Ashoka invaded Kalinga in 261 B.C. Nearly one lakh soldiers lost their lives in the Kalinga War and one and half lakh soldiers were captured. During Ashoka's invasion the capital of Kalinga was Toshali near Dhauli. The vast wealth, military power and the maritime activities of the Kalinga was the cause of jealousy for the Magadha empire. Though both Emperor Chandragupta Maurya and Bindusar wanted to conquer Kalinga, neither ventured a war with Kalinga. After the death of Ashoka, the Great Kharavela became the emperor of Kalinga. He was the monarch of the Chedi Dynasty. The inscription found in the Elephant Caves of Khandagiri and Udaigiri mountains near Bhubaneswar describes in detail the reign of Emperor Kharavela.
