Kharavela (also transliterated Khārabēḷa) was a monarch of Kalinga in present-day Odisha, India, who ruled during the second or first century BCE. The primary source for Kharavela is his rock-cut Hathigumpha inscription. The inscription is undated, only four of its 17 lines are completely legible, others unclear, variously interpreted and disputed by scholars. The inscription written with Jainism-related phrases recites a year by year record of his reign and panegyrically credits him with public infrastructure projects, welfare activities, patronage of the arts, and many military victories. Historians agree that it is best and most complete biography of Kharavela available. He was a follower of Jainism. Much of the available information about Kharavela comes from the undated, much damaged Hathigumpha inscription and several minor inscriptions found in the Udayagiri and Khandagiri Caves in present-day Odisha. The Hathigumpha inscription records Kharavela's life until his 38th year, including 13 years of his reign. The inscription is badly damaged; of its 17 lines, only four are completely legible, the rest partly lost and eroded by natural processes. It is open to "widely different" interpretations, giving rise to disputes and speculation by various scholars. The kingdom of Kalinga was annexed by Ashoka c. 262-261 BCE. The Hathigumpha inscription implies that Kalinga regained its independence from the Maurya Empire sometime after Ashoka's death, and Kharavela was born in an independent Kalinga. In 1885, the colonial era eipgraphist Bhagwan Lal Indraji read the 16th line of the Hathigumpha inscription as a reference to Maurya kala and 165th year after this new timeline, which he called the Mauryan era. Indraji concluded that Kharavela was born in 127 BCE and became king in 103 BCE. Indraji's interpretations were questioned by scholars and has been largely rejected. According to Sudhakar Chattopadhyaya, the 16th line does not mention Maurya kala ("Maurya era") but reads Mukhya kala ("the main era").
