made up of Yavanas (Greeks), Kambojas, Shakas (Scythians), Kiratas (Nepalese), Parasikas (Persians) and Bahlikas (Bactrians) who took Pataliputra. In 305 BC, Seleucus I led an army to the Indus, where he encountered Chandragupta. The confrontation ended with a peace treaty, and "an intermarriage agreement" (Epigamia, Greek: Ἐπιγαμία), meaning either a dynastic marriage or an agreement for intermarriage between Indians and Greeks. Accordingly, Seleucus ceded to Chandragupta his northwestern territories, possibly as far as Arachosia and received 500 war elephants (which played a key role in the victory of Seleucus at the Battle of Ipsus): The details of the marriage agreement are not known, but since the extensive sources available on Seleucus never mention an Indian princess, it is thought that the marital alliance went the other way, with Chandragupta himself or his son Bindusara marrying a Seleucid princess, in accordance with contemporary Greek practices to form dynastic alliances. An Indian Puranic source, the Pratisarga Parva of the Bhavishya Purana, described the marriage of Chandragupta with a Greek ("Yavana") princess, daughter of Seleucus, before accurately detailing early Mauryan genealogy: Chandragupta, however, followed Jainism until the end of his life. He got in his court for marriage the daughter of Seleucus Nicator, Berenice (Suvarnnaksi), and thus, he mixed the Indians and the Greeks. His grandson Ashoka, as Woodcock and other scholars have suggested, "may in fact have been half or at least a quarter Greek." Also several Greeks, such as the historian Megasthenes, followed by Deimachus and Dionysius, were sent to reside at the Mauryan court. Presents continued to be exchanged between the two rulers. The intensity of these contacts is testified by the existence of a dedicated Mauryan state department for Greek (Yavana) and Persian foreigners, or the remains of Hellenistic pottery that can be found throughout northern India. On these occasions, Greek populations apparently remained in the northwest of the Indian subcontinent under Mauryan rule. Chandragupta's grandson Ashoka, who had converted to the Buddhist faith declared in the Edicts of Ashoka, set in stone, some of them written in Greek, that Greek populations within his realm also had converted to Buddhism: In his edicts, Ashoka mentions that he had sent Buddhist emissaries to Greek rulers as far as the Mediterranean (Edict No. 13), and that he developed herbal medicine in their territories, for the welfare of humans and animals (Edict No. 2). The Greeks in India even seem to have
