C.E and 313 B.C.E, Chandragupta seized the weakened state of Magadha from Nanda. Chandragupta's conquests included reconquering the parts of northwest India that Alexander had claimed, using the formidable army remaining from Magadha to drive the Macedonian control into Afghanistan. By conquering these territories, Chandragupta was able to establish himself as the sole ruler of Northern India, allowing him to found the Mauryan dynasty. To assist in the ruling of an empire, Chandragupta adopted the Persian concept of dividing extensive claimed lands into provinces, with an appointed head attributed to each one. Members of Chandragupta's family, establishing a bureaucracy tasked with operating the state through taxation, often ruled these provinces. For the first time in Indian history a single ruler maintained most of the subcontinent, control exercised through delegated power. There to assist him with designing his bureaucratic system was Chandragupta's trusted adviser and minister, Kautilya. Kautilya urged the king to further his political power and increase allies who shared mutual enemies. This adviser assisted Chandragupta throughout the duration of his reign, and assisted not only in establishing the bureaucracy, but also in preserving documentation utilized today that provides information pertaining to the Mauryan name. Chandragupta, with the assistance of Kautilya, ruled until his abdication in favor of his son in 301 B.C.E. It is rumored that following his abdication, Chandragupta retired to a Jain monastery where he fasted to death. .
Following the reign of Chandragupta was that of his son, Bindasura. Under the rule of Bindasura, the Mauryan empire was extended and consolidated. The administrative system of government was maintained under Bindasura, but little knowledge remains as to the technicalities of his reign. He is best known for his campaign in the Deccan, better known as the southern peninsula of India.
