Vasudeva Anakadundubhi in the context of "Balarama"

Vāsudeva (/ˌvɑːsuˈdeɪvə/; Sanskrit: वासुदेव [ʋɑːsudéːʋɐ]), later incorporated as Vāsudeva-Krishna (Vāsudeva-Kṛṣṇa, "Krishna, son of Vasudeva"), Krishna-Vāsudeva or simply Krishna, was the son of Vasudeva Anakadundubhi, king of the Vrishnis in the region of Mathura. He was a leading member of the legendary Vrishni heroes, and may well have been a historical ruler in the region of Mathura.

Vāsudevism arose with the decline of Vedism in India, which occurred during the 8th to 6th century BCE. Vāsudeva then became the object of one of the earliest forms of personal deity worship in India, and is attested from around the 4th century BCE. At that time, Vāsudeva was already considered as a deity, as he appears in Pāṇini's writings in conjunction with Arjuna as an object of worship, since Pāṇini explains that a vāsudevaka is a devotee (bhakta) of Vāsudeva.

Yashoda (Sanskrit: यशोदा, IAST: Yaśodā) is the foster-mother of Krishna and the wife of Nanda. She is described in the Puranic texts of Hinduism as the wife of Nanda, the chieftain of Gokul, and the sister of Rohini. According to the Bhagavata Purana, Krishna was born to Devaki, but Krishna's father, Vasudeva, brought the newborn Krishna to his cousin Nanda, and his wife, Yashoda, in Gokulam. This was for his upbringing, as well as to protect Krishna from Devaki's brother, Kamsa, the tyrannical king of Mathura.
