ナンダ朝
Gangaridai (; Latin: Gangaridae) is a term used by the ancient Greco-Roman writers to describe a people or a geographical region of the ancient Indian subcontinent. Some of these writers state that Alexander the Great withdrew from the Indian subcontinent because of the strong war elephant force of the Gangaridai. The writers variously mention the Gangaridai as a distinct tribe. However, the geographical region was annexed and governed by the Nanda Empire at the time.
