The Mauryan Empire, founded by Chandragupta Maurya, would first conquer the Nanda Empire. Chandragupta would then defeat the Seleucid Empire during the Seleucid-Mauryan War. This resulted in the transfer of the Macedonian satraps in the Indus Valley and Gandhara to the Mauryan Empire. Furthermore, a marriage alliance was enacted which granted Seleucus's daughter as Chandragupta's wife for diplomatic relations. The conflict additionally led to the transfer of 500 war elephants to the Seleucid Empire from the Mauryan Empire, presumably as expenses of lives lost and damages sustained.
