was led by Junayd ibn Abd al-Rahman al-Murri or by Al Hakam ibn Awana , a general and governor of Sindh under the Umayyad caliph Hisham ibn Abd al-Malik. Al-Baladhuri mentions the conquests of several other places by these invaders, but about Ujjain, he only mentions that the city was invaded. This appears to be a tacit admission that the invasion was unsuccessful. The semi-legendary Guhila ruler Bappa Rawal is also said to have repulsed an Arab invasion. Historian R. V. Somani theorizes that he was a part of an anti-Arab confederacy formed by Nagabhata. Rashtrakuta invasion Nagabhata appears to have been defeated by the Rashtrakuta ruler Dantidurga. According to the Rashtrakuta records, the ruler of Malava was among the kings defeated by Dantidurga. The Sanjan inscription of Dantidurga's descendant Amoghavarsha states that Dantidurga performed a religious ceremony at Ujjayini (Ujjain, the capital of Nagabhata). During this ceremony, the Lord of Gurjara (Gurjaresha) acted as a pratihara (door-keeper) of Dantidurga. The usage of the word pratihara seems to be a word play, suggesting that the Rashtrakuta king subdued the Gurjara-Pratihara king who was ruling Avanti at that time. Identification with Nagavaloka The 756 CE Hansot inscription of a Chahamana ruler Bhartrvaddha records the grant of a village during the reign of his overlord Nagavaloka. D. R. Bhandarkar and other historians have identified Nagavolka with Nagabhata. If this assumption is true, it is possible that after the Rashtrakutas left, Nagabhata regained his power, and conquered the area around Bhrigukachchha (Bharuch), where a Chahamana branch ruled under his suzerainty. According to historian B. N. Puri, Nagabhata may have conquered this region from Chalukya feudatory Avanijanashraya Pulakeshin. Thus, besides Malwa, Nagabhata's kingdom may have comprised parts of present-day Gujarat and Rajasthan. Other The Ragholi copper-plate inscription of the Shaila dynasty ruler Jayavardhana states that his ancestor Prithuvardhana defeated a Gurjara ruler. R. C. Majumdar believed that the defeated ruler might have been Nagabhata. However, B. N. Puri disagrees with this theory, and believes that Prithuvardhana ruled around 694 CE, several years before Nagabhata's ascension. An inscription of Gallaka, a subordinate of Vatsaraja, in the year 795 regards Nagabhata I as the one who had acquired victory over the "invincible Gurjaras" and obtained fame. Thus, even though the dynasty is called Gurjara-Pratiharas, it is certain that the kings themselves were not from Gurjara tribe.
