Chandragupta is considered the first authentic emperor of India since he was the founder of the Maurya Empire as well as who managed to unify most of the territory of the Indian subcontinent.
According to the inscription in the Allahabad Pillar, one of the pillars of Ashoka which are a series of columns dispersed throughout India, Chandragupta called his son, Samudragupta, a noble person in front of the courtiers, appointing him to "protect the earth". Such description suggests that this lead to the Chandragupta's renounce from the throne and his son’s appointment as the next king.
