Mahapadmananda was the first ruler of the Nanda Dynasty. There are several theories about the birth of Mahapadmananda. The Purana theory say that Mahapadmananda was son of Nandivardhana & a Shudra Woman. Another theory says that there was a good-looking barber, who won the heart of a queen who subsequently killed the king. Mahapadmananda was a son of this barber. Whatever may be correct but this was the line which started the trend of lowborn (as of contemporary conditions) rule started in Magadha.
