Brihadratha dynasty
The Brihadratha dynasty (Sanskrit: बृहद्रथ; IAST: Bṛhadratha) was the first ruling dynasty of Magadha. Brihadratha was the founder of the dynasty. According to the Vishnu Purana, Magadha, mentioned in Atharvaveda, was not only the most valuable kingdom in the Vedic period but was also the center of civilization and power in India. The name of Brihadratha is found in the Rigveda (I.36.18, X.49.6). The Puranic sources say that Brihadratha was the eldest son of Uparichara Vasu. According to the Ramayana, Uparichara Vasu founded Vasumati and Girivraja, the capital of the dynasty. History

Brihadratha 

Brihadratha (also Maharatha) was the king of Magadha and the founder of the Brihadratha dynasty. According to the Mahabharata and the Puranas, he was the eldest of the five sons of Uparichara Vasu, the Kuru king of Chedi and his queen was Girika. Jarasandha 

Puranas mention that Jarasandha was the son of Sambhava, Mahabharatha states that Jarasandha was the son of Brihadratha and the greatest ruler of the dynasty. According to ancient texts there were 24 Brihadratha kings who ruled for many years. However, the Vayu Purana, Matsya Purana and Vishnu Purana disagree regarding the Brihadratha period of rule. The astronomical works based on the Vishnu Purana states that Brihadratha dynasty lasted for 1000 years. The name of Jarasandha appears in the Puranas many times. Jarasandha was inimical to the Yadavas and is mentioned as a villain in the Mahabharta. Bhima, with the help of Krishna, killed Jarasandha. Sahadeva
