The Second Battle of Eran, which took place around 510 CE, was a pivotal battle between the Gupta Empire's Emperor Bhanugupta and the Huna army of Toramana. The battle, which finds mention in the Eran inscription, was fought at the cost of the death of Bhanugupta's general, Goparaja. It was a key battle in halting the Huna invasion of eastern Malwa or attempting to expel them from the region. The battle was the first of a series of reverses for the Huna conqueror. In his battle against the invaders, Bhanugupta might have had the support of King Prakāśadharman, the king of Mandasor.
