Shurparaka (IAST: Śūrpāraka; also spelt Surparaka) was a kingdom founded by Bhargava Rama (also known as Parashurama) near the Western sea, close to the mouth of the river Narmada in India. It is mentioned in the epic Mahabharata. Parashurama gave this kingdom to the Brahmin rulers of Kashyapa clan. Shurparaka is identified with medieval Sopara and modern day Nala Sopara.
The Ocean created for Jamadagni’s son (Bhargava Rama), a region called Shurparaka (12:49). Having made the earth destitute of Kshatriyas for thrice seven times, the puissant Bhargava, at the completion of a horse-sacrifice, gave away the earth as sacrificial present unto Kashyapa. Kashyapa having accepted the earth in gift, and made a present of it unto the Brahmanas, entered the great forest.
This gave rise to the myth of Parashurama, reclaiming the land from the sea. The people of Shurparaka brought this myth to Kerala where this myth still exists.
One should proceed to Shurparaka, where Jamadagni’s son had formerly dwelt. Bathing in that tirtha of Rama, one acquireth the merit of giving away gold in abundance. (3:85). In the tirtha called Shurparaka are two sacrificial platforms of the illustrious Jamadagni, called Pashana and Punaschandra (3:88). Yudhishthira plunged his body in all the holy spots, and then came again to Shurparaka (3:118). Bathing in the Narmada as also in the tirtha known by the name of Shurparaka, observing a fast for a full fortnight, one is sure to become in one’s next birth a prince of the royal line. (13:25).
