Ahichchatra kingdom of Panchala
The Panchala janapada was located in Uttar Pradesh, originally stretching from the Himalayas to the river Chambal. However, at some point, it was divided into two parts. Uttar (or northern) Panchala consisted of the Rohilkhand area, north of the Ganges, with its capital at Ahichhatra. Dakshina (or southern) Panchala comprised the area soouth of the Ganges and north of the Chambal, with its capital at Kampila, in modern Farrukhabad district.
Some time in the first half of the sixth century BCE, Uttar Panchala was was conquered by the Kurus, and only Dakshina Panchala remained independent. It was eventually absorbed into the Magadhan empire by Mahapadma Nanda around 350 BCE.
