So also the king's acts of prowess and courage were believed to be due to magical aid. According to the common belief Siddharája did his great acts of heroism by the help of a demon named Bábaro, whom he is said to have subdued by riding on a corpse in a burying ground. The story in the Prabandhachintámani is similar to that told of the father of Harshavardhana who subdued a demon with the help of a Yogí. It is notable that the story had passed into its present form within a hundred years of Siddharája's death. Somesvara in his Kírtikaumudí says, 'This moon of kings fettered the prince of goblins Barbaraka in a burial-place, and became known among the crowd of kings as Siddharája.' Older records show that the origin of the story, at least of the demon's name, is historical being traceable to one of Siddharája's copperplate attributes Barbaraka-jishnu that is conqueror of Barbaraka. The Dvyásrayakosha represents this Barbara as a leader of Rákshasas or Mlechhas, who troubled the Bráhmans at Srísthala-Siddhapura. Jayasimha conquered him and spared his life at the instance of his wife Pingaliká. Afterwards Barbara gave valuable presents to Jayasimha and 'served him as other Rájputs.' [579] Barbaraka seems to be the name of a tribe of non-Áryans whose modern representatives are the Bábariás settled in South Káthiáváda in the province still known as Bábariáváda. A Dohad inscription of the time of Siddharája dated A.D. 1140 (S. 1196) says of his frontier wars: 'He threw into prison the lords of Suráshtra and Málwa; he destroyed Sindhurája and other kings; he made the kings of the north bear his commands.' The Suráshtra king referred to is probably a ruler of the Áhír or Chúdásamá tribe whose head-quarters were at Junágadh. According to the Prabandhachintámani Siddharája went in person to subdue Noghan or Navaghani the Áhír ruler of Suráshtra; he came to Vardhamánapura that is Vadhván and from Vadhván attacked and slew Noghan. Jinaprabhasúri the author of the Tírthakalpa says of Girnár that Jayasimha killed the king named Khengár and made one Sajjana his viceroy in Suráshtra. So many traditions remain regarding wars with Khengár that it seems probable that Siddharája led separate expeditions against more than one king of that name. According to tradition the origin of the war with Khengár was a woman named Ránakadeví whom Khengára had married. Ránakadeví was the daughter of a potter of Majevádi village about nine miles north of Junágadh, so famous for her beauty that Siddharája determined to marry her. Meanwhile she had accepted an offer from Khengár whose subject she was and had married him. Siddharája enraged at her marriage advanced against Khengár, took him prisoner, and annexed Sorath. That Khengár's kingdom was annexed and Sajjana, mentioned by Jinaprabhasúri, was appointed Viceroy is proved by a Girnár inscription dated A.D. 1120 (S. 1176).
