Chandragupta Maurya established the Maurya dynasty. He came into power at Magadha in 321 B. C. E.
Chanakya, also known as Kautilya or Vishnugupta, was his chief advisor. Arthasasthra is the work of Chanakya. It discusses how a powerful and effective administration should be organised.
Kautilya, in his Arthashastra mentions about the seven elements essential for a state. They are known as the "Saptangas" (Seven limbs). That which has all these seven elements would be considered a state.
