Brihadratha, also known as Maharatha, was the founder of the Barhadratha dynasty, the earliest ruling dynasty of Magadha. According to the Mahabharata and the Puranas, he was the eldest of the five sons of Vasu, the Kuru king of Chedi and his queen Girika. The name of Brihadratha is also found in the Rigveda (I.36.18, X.49.6).
Successors of Brihadhartha 
All the Puranas mention his sister amna, as his successor. Kushagra was succeeded by his son Vrishava (or Rishava). Pushpavanta (or Pushyavanta or Punyavanta) was the son of Vrishava. Pushpavanta was succeeded by his son Satyahita (or Satyadhrita). Satyahita's son was Sudhanvana (or Sudharmana, Dharmatma of Dhanusha). Dhanusha was succeeded by his son Sarva (or Urja or Jatu or Jahu or Jantu). Sarva was succeeded by his son Sambhava. According to the Agni Purana, Sambhava was succeeded by his son Jarasandha, the noted warrior king mentioned in the Mahabharata. But all other Puranic genealogical lists mention the name of Brihadratha again between either Jantu and Jarasandha or Sambhava and Jarasandha. Jarasandha was succeeded by his son Sahadeva who was killed in the Kurukshetra war.
