The Defender: Battle of Rajasthan
738 CE: When the Wall Held
The Battle of Rajasthan in 738 CE marked the decisive confrontation between Nagabhata's confederacy and Arab forces under Junaid. This engagement stopped Arab expansion into India and validated the confederacy strategy. Through superior coordination, knowledge of terrain, and unified purpose, the Hindu kingdoms demonstrated that organized resistance could overcome even the powerful Arab armies.
The Storm Gathers
By early 738 CE, the confrontation that Nagabhata I had been preparing for became inevitable. Junaid ibn Abd al-Rahman al-Murri, the ambitious governor of Sindh, had consolidated his position and secured reinforcements from the Umayyad Caliphate. His target was clear: the wealthy kingdoms of Gujarat and Rajasthan, gateway to the even richer territories of the Gangetic plain.
Junaid had already demonstrated his military capabilities, conquering smaller kingdoms and extracting tribute from those too weak to resist. His army was disciplined, experienced, and motivated by both religious zeal and the promise of plunder. Arab military tactics had proven devastatingly effective across three continents, and Junaid had every reason to believe that the fragmented Hindu kingdoms would fall as so many others had before them.
The Confederate Response
What Junaid didn't fully appreciate was that the political landscape had changed. Nagabhata had spent years preparing for exactly this moment. His intelligence network tracked Arab movements, providing advance warning of the invasion's scale and direction. He activated the alliance system he had built, calling on his confederate kings to honor their commitments.
The response exceeded expectations. Bappa Rawal of Mewar, the legendary Guhila ruler who had already proven himself against Arab raiders, brought the fierce warriors of Chittorgarh. The Chahamanas of Sapadalaksha contributed their cavalry. Most significantly, Chalukya emperor Vikramaditya II recognized the shared threat and dispatched his son Avanijanashraya Pulakeshi with a substantial force to coordinate a southern front. This was no longer a regional defense but a pan-Indian resistance.
Warriors gathered at predetermined assembly points, bringing not just their own forces but also contingents from smaller allied clans. The confederation's military protocols, developed through joint training exercises and smaller collaborative campaigns, now faced their ultimate test.

Two Fronts: Rajasthan and Navsari
The defensive campaign of 738-739 CE was fought on two fronts. In the north, Nagabhata commanded the confederate forces in Rajasthan and Malwa, directly confronting Arab armies that had advanced toward Ujjain. The geography of Rajasthan, with its rocky terrain, limited water sources, and extreme climate, favored defenders who knew the land.
