Anguttara Nikaya
Asmaka was located around and between the river Godavari. It included areas in present-day Telangana, and Maharashtra. It was one of the "shodasa" (sixteen) Mahajanapadas in the 6th century BCE, mentioned in the Buddhist text "Anguttara Nikaya". Puranas mention Asmaka as one of the conquered territories of the Nandas in the 5th or 4th century BCE.
