The Mahameghavahanas (c. 250s BCE-400s CE) was an ancient ruling dynasty of Kaḷinga after the decline of the Mauryan Empire. The third ruler of the dynasty, Khārabēḷa, conquered much of India in a series of campaigns at the beginning of the common era. Kaḷingan military might was reinstated by Khārabēḷa: under Khārabēḷa's generalship, the Kaḷinga state had a formidable maritime reach with trade routes linking it to the then-Simhala (Sri Lanka), Burma (Myanmar), Siam (Thailand), Vietnam, Kamboja (Cambodia), Borneo, Bali, Samudra (Sumatra) and Jabadwipa (Java). Khārabēḷa led many successful campaigns against the states of Magadha, Anga, the Satavahanas and the South Indian regions ruled by the Pandyan dynasty (modern Andhra Pradesh) and expanded Kaḷinga as far as the Ganges and the Kaveri.
