The Veraval prashasti also states that Kumarapala defeated the king of Jangala (another name for the Chahamana territory). Vigraharaja IV Arnoraja's son Vigraharaja IV launched several expeditions against the Chaulukyas to avenge his father's defeat. According to the Bijolia rock inscription, he killed one Sajjana, a feudatory (samanta) of Kumarapala at Chitrakuta (Chittor). The Jain author Somatilaka Suri states that Vigraharaja's army captured Sajjana's elephant force. While Vigraharaja was busy fighting at Chittor, Kumarapala tried to create a diversion by besieging Nagaur, but lifted the siege after learning about Vigraharaja's victory at Chittor. Vigraharaja also subdued the Chahamanas of Naddula, who were feudatories of Kumarapala. The Bijolia inscription boasts that he destroyed the enemy cities of Javalipura (Jalore), Pallika (Pali) and Naddula (Nadol). The Naddula ruler subdued by him may have been Alhanadeva. Vigraharaja also defeated one Kuntapala, who can be identified with a Naddula Chahamana subordinate of Kumarapala. A Chahamana prashasti (eulogy) boasts that Vigraharaja reduced Kumarapala to a karavalapala (probably the designation of a subordinate officer). This is obviously an exaggeration, but it does appear that Vigraharaja conquered some of Kumarapala's territories. The Chahamana-Chaulukya relations probably became normal when Arnoraja's son Someshvara became the Chahamana king in later years, possibly with support from Kumarapala. Paramaras of Abu The writings of Prabhachandra, Jayasimha Suri, and Jina-Mandana Suri mention Kumarapala's conflict with Vikramasimha, a ruler of the Paramara branch of Abu. Kumarapala passed through Abu during his march against Arnoraja. Vikramasimha considered Kumarapala an usurper, and made a plan to assassinate him. He invited Kumarapala to dinner at his palace, but Kumarapala sent his officers instead. One of these officers told Kumarapala about Vikramasimha's treacherous plan. After defeating Arnoraja, Kumarapala returned to Abu, and had Vikramasimha imprisoned. He appointed Vikramasimha's nephew Yashodhavala as the new chief of Abu. Chahamanas of Naddula The Chahamanas of Naddula were the northern neighbours and longstanding rivals of the Chaulukyas. Asharaja, a former king of Naddula, had accepted Chaulukya suzerainty during Jayasimha's reign, after being dislodged by his nephew Ratnapala. Asharaja's son Katukaraja seized the throne of Naddula around 1145 CE. His inscriptions of Katukaraja are dated in the Simha calendar era, which was used in the present-day Gujarat region. Based on this, historian R. B. Singh believes that he captured Naddula with help of Kumarapala. Katukaraja's younger brother and successor Alhanadeva ruled as Kumarapala's vassal. After becoming Kumarapala's feudatories, the Chahamanas of Naddula suffered
