Eighth Century (Muslim Rajputana)

Battle of Rajasthan
The Battle of Rajasthan was a battle between Hindu states and the Ummayad Caliphate in 730 AD. The Hindu states were at first successful in repelling the Arabs but, ultimately, the Hindu states involved in the conflict were defeated due to the greater numbers of the Arabs despite much bloodshed occurring. It proved the bravery and valour of Hindus but, despite it, the Hindus lost Rajasthan to the Arabs. The war made the Arabs realize that the Arab invasion of Hind would be very difficult, and a massive troop buildup along the new Hindu-Arab border was made.

Invasion
Arabs invaded Punjab in 731 AD, where many thousands of troops were slaughtered and, famously, the Arabs began with a 200,000 person strong army and ended with 150,000 troops alive. Despite this slaughter, the Arabs conquered the entirety of Punjab by 732 AD. After the Battle of Punjab, many Indians defected to the Arabs and were captured. Due to this, many Indian techniques were learned by the Arabs and the advance continued the following year. Delhi fell to the Ummayads the following year and a final push against the Pala in 736 AD led to a stall in the war as Muslim advance slowed heavily. A new technique of harassment and raids began for 5 years before the Pala were defeated in a similar ease as with the Sassanians in 741 AD. The Indian campaign took a massive troop buildup and ten years, but the wealth in diamonds, gold, silver, and knowledge would contribute to the Caliphate.
