Chandragupta Maurya
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.
