Modern historians generally identify the ruler of the Gangaridai and the Prasii mentioned in ancient Greco-Roman accounts as a Nanda king. The chroniclers of Alexander the Great, who invaded north-western India during 327–325 BCE, characterise this king as a militarily powerful and prosperous ruler. The prospect of a war against this king led to a mutiny among the soldiers of Alexander, who had to retreat from India without waging a war against him.
