Barhadradha Dynasty Before the Mahabharata War of 3138 B.C.
1. Barhardradha I :-
According to Mahabharata, Brihadradha-I, the founder of Barhadradha Dynasty was the eldest son of Uparichara Vasu , the seventh in the descent from the Great Kuru, son of Samvarna, a descendant of the Lunar Dynasty (Chandravamsajah) of kings. He founded the kingdom of Magadha probably about 3709 B.C. or 571 years before the Great war of Mahabharata at Kurukshetra between the Pandavas and the Kauravas.
This battle according to Mahabharata, the important Puranas, and all other ancient Hindu, Bauddha and Jaina authorities and traditions, took place. 36 years before the commencement of the Kaliyuga—the present Yuga. Kali Yuga began immediately after the departure of Sri Krishna, son of Vasudeva by Devaki, from this world on the 20th February, 3102 B. C., in the year Pramadhin of the Southern School of Hindu astronomers. (Vide Indian Eras By this author, Kota Venkata Chelam)
Brihadradha married the two beautiful twin daughters of the king of Kasi; and by the blessing of a Rishi, he obtained a most powerful son by name Jarasandha. The king, after installing his mighty son Jarasandha on the throne of Magadha retired into a forest and led an ascetic life. In this context the Mahabharata gave the next prominent dynasty of Jarasandha, leaving some generations of kings in the interval between Brihadradha I and Jarasandha (or Brihadradha II). - (Vide_Mahabharata, Sabha Parva. Adhyayas 14 to 19).
N.B:- The Matsya Purana enumerates all the names of kings between Brihadradha-I and Jarasandha or Brihadradha-II Jarasandha, son of Bhuvana was the 15 th in descent from Kuru and the tenth from Brihadradha-I, the founder of the Magadha Dynasty of kings. The following table shows the order of descent according to Matsya Purana. (Chapter 59):-
