short time, before being defeated by the Paramara king Bhoja. Neighbouring rivalries Durlabharaja was succeeded by his nephew Bhima I, who faced an invasion from the Ghaznavid ruler Mahmud during 1024-1025 CE. Bhima fled to Kanthkot, as Mahmud entered the Chaulukya territory unopposed and sacked the Somnath temple. After Mahmud's departure, Bhima restored the Chaulukya rule. He crushed revolts by the Paramara chiefs of Arbuda, who used to serve as Chaulukya vassals. Bhima also defeated and imprisoned Krishnadeva, a ruler of the Paramara branch of Bhinmal. He unsuccessfully fought against the Naddula Chahamana ruler Anahilla. Anahilla's sons Balaprasada and Jendraraja defeated Bhima and forced him to release Krishnadeva. Later legendary accounts credit Bhima with a victory against Hammuka, a ruler of Sindh, although the accuracy of this claim is not certain. Semi-legendary accounts suggest that Bhima formed an alliance with the Kalachuri king Lakshmi-Karna, and the two played an important role in the downfall of the Paramara king Bhoja around 1055 CE. According to the 14th century chronicler Merutunga, Bhima and Lakshmi-Karna invaded Bhoja's kingdom of Malwa from two opposite directions, and Bhoja died of a disease during this invasion. Some Chaulukya chroniclers boast that Bhima annexed Bhoja's capital Dhara or that he captured Bhoja alive, but these claims are not corroborated by historical evidence. After Bhoja's death, a rivalry developed between the Bhima and Lakshmi-Karna over sharing the spoils of their victory. Bhima's son Karna succeeded him around 1064 CE. Bhoja's brother Udayaditya, supported by the Shakambhari Chahamana king Vigraharaja III, forced Karna to retreat from Malwa. Meanwhile, the Kalachuris managed to capture the Lata region. By 1074 CE, Karna evicted the Kalachuris from Lata, and annexed the region to the Chaulukya kingdom, before losing it to one Trivikramapala within three years. The Naddula Chahamana ruler Prithvipala defeated Karna, and his successor Jojalladeva occupied the Chaulukya capital Anahilapataka, possibly when Karna was busy at another place. The Shakambhari Chahamana king Durlabharaja III also appears to have achieved some military success against Karna, although the Chahamana descriptions of this victory are highly exaggerated. According to legendary chronicles, Karna also defeated Bhil and Koli tribals, who used to raid the Chaulukya territories. He established a city called Karnavati after defeating a Bhil chief named Asha (Āśā). Karnavati is identified with modern Ahmedabad by some, but this is not certain.
