The Kalinga War (ended)[5] was fought in ancient India between the Maurya Empire under Ashoka the Great and Kalinga, an independent feudal kingdom located on the east coast, in the present-day state of Odisha and northern parts of Andhra Pradesh.[6] It is presumed that the battle was fought on Dhauli hills in Dhauli which is situated on the banks of Daya River. The Kalinga War was one of the largest and deadliest battles in Indian history.[7]
This is the only major war Ashoka fought after his accession to the throne, and marked the close of the empire-building and military conquests of ancient India that began with the Mauryan Emperor Chandragupta Maurya.[8] The war cost nearly 250,000 lives.[8]
According to political scientist Sudama Misra, the Kalinga janapada originally comprised the area covered by the Puri and Ganjam districts.[9]
The reasons for invading Kalinga were to bring peace and for power. Kalinga was a prosperous region consisting of peaceful and artistically skilled people. The northern part of Kalinga was known as the Utkala (Uttar: North, Kal: Kalinga), they were the first from the region to use a navy and traveled offshore to Southeast Asia for trade. For that reason, Kalinga was able to develop several ports and a skilled navy. The culture of Kalinga was a blend of tribal religions and Brahmanism co-existing peacefully.[10]
Kalinga was under the rule of the Nanda Empire who ruled over the region from their capital in Magadha until their fall in 321 BCE.[11] Ashoka's grandfather Chandragupta had possibly attempted to conquer Kalinga but had been repulsed.[12] Ashoka set himself to the task of conquering and annexing Kalinga to the vast Maurya Empire as soon as he securely established himself as the Emperor. Some scholars argue that Kalinga was a strategic threat to the Mauryas. It could interrupt communications between Mauryan capital Pataliputra and possessions in the central Indian peninsula. Kalinga also controlled the coastline for trade in the Bay of Bengal.[13]
The war was completed in the eighth year of Ashoka's reign, according to his own Edicts of Ashoka, probably in 261 BCE. After a bloody battle for the throne following the death of his father, Ashoka was successful in conquering Kalinga – but the consequences of the savagery changed Ashoka's views on war and led him to pledge to never again wage a war of conquest.
According to Megasthenes, the Greek historian at the court of Chandragupta Maurya, the ruler of Kalinga had a powerful army comprising infantry, cavalry and elephants.[14]
Ashoka had seen the bloodshed and felt that he was the cause of the destruction.[15]
Ashoka's response to the Kalinga War is recorded in the Edicts of Ashoka. The Kalinga War prompted Ashoka, already a non-engaged Buddhist, to devote the rest of his life to ahimsa (non-violence) and to dharma-vijaya (victory through dharma). Following the conquest of Kalinga, Ashoka ended the military expansion of the empire and began an era of more than 40 years of relative peace, harmony, and prosperity. [16]
