During the reign of Khārabēḷa, the Chedi dynasty of Kaḷinga ascended to eminence and restored the lost power and glory of Kaḷinga, which had been subdued since the devastating war with Ashoka. 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), Malaysia, Borneo, Bali, Samudra (Sumatra) and Jabadwipa (Java). Khārabēḷa led many successful campaigns against the states of Magadha, Anga, Satavahanas till the southern most regions of Pandyan Empire (modern Tamil Nadu).
