Maurya Empire
The Buddhist Mahavamsa Tika and Jain Parishishtaparvan records Chandragupta's army unsuccessfully attacking the Nanda capital.  Chandragupta and Chanakya then began a campaign at the frontier of the Nanda empire, gradually conquering various territories on their way to the Nanda capital. He then refined his strategy by establishing garrisons in the conquered territories, and finally besieged the Nanda capital Pataliputra. There Dhana Nanda accepted defeat. The conquest was fictionalised in Mudrarakshasa play, it contains narratives not found in other versions of the Chanakya-Chandragupta legend. Because of this difference, Thomas Trautmann suggests that most of it is fictional or legendary, without any historical basis. Radha Kumud Mukherjee similarly considers Mudrakshasa play without historical basis.
