About Haryak Dynasty
The Haryak dynasty or Haryanka Dynasty(from 544 BCE to 412 BCE) is considered to have been the second ruling dynasty of Magadha. It replaced the legendary Barhadara dynasty. It was founded by Bimbisara (544 BCE to 493 BCE). Bimbisara is considered the actual founder of the Magadha Empire.
Nagadasaka was the last ruler of the ‘Haryak dynasty’. His Amatya Shishunaga dated 412 BC took advantage of Nāgadāsaka’s weakness. He assumed the throne and established the Shishunaga Dynasty.
Downfall of Nagadasaka
Nagadasaka was very luxurious and weak. Due to his carelessness in governance, people are not satisfied with him.
His Amatya(commander) Shishunaga sought it as the opportunity to become King. He revolted the kingdom and became the king.
The Haryak Dynasty ended in 412 BCE and the Shishunaga Dynasty was established.
