In 305 BCE, Indian Emperor Chandragupta Maurya of the Maurya Empire led a series of campaigns to retake the satrapies left behind by Alexander the Great when he returned westwards. Seleucus I Nicator fought to defend these territories, but both sides made peace in 303 BCE. The treaty ended the Seleucid–Mauryan war and gave Chandragupta control of the regions he was warring for, while Seleucus was given 500 highly valued war elephants in exchange.

Chandragupta Maurya established himself as ruler of Magadha around 321 BCE. He decided to conquer the Nanda Dynasty, rulers at the time of the Gangetic Plain. He fought the empire for eleven years with successful guerrilla campaigns, and captured the Nanda capital of Pataliputra. This led to the fall of the empire and the eventual creation of the Maurya Empire under Emperor Chandragupta Maurya.

The states of the Indus Valley and modern Afghanistan were part of the Empire of Alexander the Great. When Alexander died, the Wars of the Diadochi ("Successors") split his empire apart; as his generals warred over control of the throne. In the eastern territories one of these, Seleucus Nicator, was taking control and creating the beginnings of the Seleucid Empire. This included Alexander's conquests along the Indus Valley.

The emerging and expanding Mauryan Empire now came into conflict over the Indus Valley with the efforts of Seleucus I Nicator to hold these territories.
