Gangaridai (Γανγαρίδαι, Gangaridae, in Ancient Greek meaning of Ganges, Ganga Rashtra in Sanskrit meaning Nation on the River Ganges) was an ancient state found around 300 BC where the Bengal region lies today (present-day Bangladesh and the West Bengal state in India). It was described by the Greek traveller Megasthenes in his work Indica. The Greek and Latin historians suggested that Alexander the Great withdrew from India, anticipating the valiant joint counterattack of the mighty Gangaridai and Prasii (Nanda) Empires, the latter located in central Bihar.
