the Chaulukya power. He defeated Khangara alias Navaghana, the Chudasama king of Saurashtra. The Naddula Chahamana ruler Asharaja, who had been dethroned by his rival Ratnapala, became a vassal of Jayasimha sometime before 1143 CE. Jayasimha defeated the Shakambhari Chahamana ruler Arnoraja. Later, however, Jayasimha accepted Arnoraja as an ally, and the Chahamana ruler married Jayasimha's daughter Kanchanadevi. The couple's son (and thus Jayasimha's grandson) Someshvara, was brought up at the Chaulukya court. Someshvara's sons Prithviraja III (better known as Prithviraj Chauhan) and Hariraja were also born in Gujarat. During the 1135-1136 CE, Jayasimha annexed the Paramara kingdom of Malwa, with support from Asharaja and Arnoraja. The Paramara kings defeated by him were Naravarman and his successor Yashovarman. Jayasimha continued his eastward march, and reached as far as the Chandela kingdom ruled by Madanavarman. The Chaulukya-Chandela conflict was inconclusive, with both the sides claiming victory. Jayasimha also defeated several minor rulers, including Sindhuraja, who was probably a Soomra king of Sindh. Jayasimha was succeeded by his relative Kumarapala, who spent his early life in exile to avoid persecution by Jayasimha. After Jayasimha's death, Kumarapala came back to the Chaulukya capital and ascended the throne in 1043 CE, with help of his brother-in-law Kanhadadeva. Arnoraja opposed Kumarapala's ascension to the throne, but Kumarapala defeated him decisively. Kumarapala seems to have helped Asharaja's son Katukaraja capture the throne of Naddula. Katukaraja's younger brother and successor Alhanadeva continued to rule as Kumarapala's vassal. Arnoraja's son Vigraharaja IV subdued Kumarapala's Chahamana feudatories at Naddula. The Shakambhari Chahamana-Chaulukya relations seem to have become more cordial when Arnoraja's son (and Jayasimha's grandson) Someshvara became the Chahamana king in later years, possibly with support from Kumarapala. After Jayasimha's death, the Paramara king Jayavarman I regained control of Malwa, but he was soon dethroned by an usurper named Ballala. Kumarapala captured Malwa from Ballala, who was killed by Kumarapala's Arbuda Paramara feudatory Yashodhavala in a battle. Kumarapala subdued a rebellion by his vassal Vikramasimha, a Paramara chief of Arbuda. The Paramara branch at Kiradu continued to acknowledge Kumarapala's suzerainty. In the early 1160s, Kumarapala sent an army against Mallikarjuna, the Shilahara king of northern Konkana. This campaign was probably triggered by a Shilahara raid in southern Gujarat, and ended with Mallikarjuna's death. Kumarapala's Naddula Chahamana feudatory Alhana put down disturbances in Saurashtra at Kumarapala's request. Historical evidence suggests that Kumarapala's empire extended from Chittor and Jaisalmer in the
