Seleucus Nicator, a Greek general of Alexander, held some of the land in the extreme north. Therefore, Chandragupta fought a long battle against him and at last defeated him around 305 B.C. and a treaty was signed. According to this treaty, Seleucus Nicator ceded the trans-Indus territories – namely Aria (Heart), Arachosia (Kandahar), Gedrosia (Baluchistan) and Paropanishae (Kabul) – to the Mauryan Empire and in exchange Chandragupta made a gift of 500 elephants to Seleucus. He (Seleucus) also gave his daughter in marriage to the Mauryan prince or it is supposed that Chandragupta married Seleucus’s daughter (a Greek Macedonian princess) as a gift from Seleucus to formalize an alliance. In this way he took his control over Indus region, some part of which is now in modern Afghanistan. Later he moved towards Central India and occupied the region, north of Narmada River.
In addition to this treaty, Megasthenese was sent by Seleucus to the court of Chandragupta and Deimakos to Bindusar’s court as Greek ambassadors. Chandragupta embraced Jainism towards the end of his life and stepped down from the throne in favour of his son Bindusara. Later he (Chandragupta) along with Jain monks led by Bhadrabahu went to Sravana Belgola, nearby Mysore and starved himself to death in typical Jaina fashion.
