Shaktar and Chanakya (also known as Kautilya or Vishnugupta), two famous Prime Ministers of the Magadh Empire belonged to Kusumpur or present day Khagaul during Fourth Century BC. Chanakya had provided initial education and training to Chandagupta Maurya (Great Emperor of Magadh Empire and Founder of the Maurya Dynasty) at this very place. Under the guidance of Chanakya, the mighty Magadh Empire was spread from present day India, Bangladesh, Pakistan, Afghanistan up to Iran after defeating the forces of Alexander and Seleucus. The tyrannical rule of the King Dhanananda over Magadh was brought to an end by the rebellion of Chanakya after arrest, humiliation and death sentence inflicted against his father Chanak by the tyrannical King Dhanananda. Thereafter, Chandragupta Maurya, disciple of Chanakya, was made King Emperor of the Magadh Empire and Chanakya became its Prime Minister. Chanakya was a great scholar, economist, administrator, jurist, lawmaker and a very sharp minded nationalist and shrewd politician. He was a student of the Takshashila or Taxila University, and also worked as an Acharya or professor in the same university. Under the guidance of Chanakya, the mighty Magadh Empire had become the most powerful, most influential, most developed and the richest empire of the world, and Pataliputra had become the most beautiful city.
