Thus, Yudhishthira, the Pandava King, could complete his campaign of bringing the whole of India into his empire. Jarasandha had friendly relations with Chedi king Shishupala, Kuru king Duryodhana and Anga king Karna. His descendants, according to the Vayu Purana, ruled Magadha for 1000 years followed by the Pradyota dynasty, which ruled for 138 years from 799 to 684 BCE. However, there is insufficient evidence to prove the historicity of this claim. These rulers are nonetheless mentioned in the Hindu, Buddhist, and Jain texts. Palaka, the son of the Avanti king Pradyota, conquered Kaushambi, increasing the kingdom's power.
