In the concluding portion of the Uttara or Supplemental Book, the descendants of Rama and his brothers are described as the founders of the great cities and kingdoms which flourished in Western India in the fourth and fifth centuries before the Christian Era.
- Rama had two sons, Lava and Kusa. The former ruled in Sravasti, which was the capital of Oudh at the time of the Buddha in the fifth and sixth centuries before Christ. The latter founded Kusavati at the foot of the Vindhya mountains.
- Bharat had two sons, Taksha and Pushkala. The former founded Taksha-sila, to the east of the Indus, and known to Alexander and the Greeks as Taxila. The latter founded Pushkala-vati, to the west of the Indus, and known to Alexander and the Greeks as Peukelaotis. Thus the sons of Bharat are said to have founded kingdoms which flourished on either side of the Indus river in the fourth century before Christ.
- Lakshman had two sons, Angada and Chandraketu. The former founded the kingdom of Karupada, and the latter founded the city of Chandrakanti in the Malwa country.
- Satrughna had two sons, Suvahu and Satrughati. The former became king of Mathura, and the latter ruled in Vidisha.
