In the beginning of 14th century the king of Goura, Firoz Shah succeed to win Egarosindur. In 1338 Sultan Fakruddin Mubarak Shah take the authorization of this ancient land. It was seemed that when Sultan was in a critical position, he took shelter in Egarosindur. In 1577 Isa Khan declared Egarosindur a sovereign state. In his age this place appeared as a remarkable place of trade and commerce. In the fort of Egarosindur there held a massive battle between Isa Khan and Mansingh, the general of Akbar. But in the battlefield Mansingh was greatly impressed by the boldness and hospitality of Isa Khan. In one stage when they carried out a duel, Mansingh's sword broke down. Isa Khan did not take his life and most surprisingly he offered his own sword to Mansingh. He said, "I could not kill any helpless person". And then they made an agreement in the battlefield. Akbar granted Isa Khan a jaigir lease over 22 pargonas. After Isa Khan, Egarosindur as a distinct entity was again lost to history.
