The Lunar dynasty (IAST: Candravaṃśa) is a lineage or dynasty which claims to be descended from Chandra or Soma (the Hindu lunar deity).
According to the Shatapatha Brahmana, Pururavas was the son of Budha (himself often described as the son of Soma) and the gender-switching deity Ila (born as the daughter of Manu). Pururavas's great-grandson was Yayati, who had five sons named Yadu, Turvasu, Druhyu, Anu, and Puru. These seem to be the names of five Vedic tribes as described in the Vedas.
Pururavas (Sanskrit: पुरूरवस्, Purūravas) is a character in Hindu literature, a king who served as the first of the Lunar dynasty.
According to the Vedas, he is a legendary entity associated with Surya (the sun) and Usha (the dawn), and is believed to reside in the middle region of the cosmos. The Rig Veda (X.95.18) states that he was a son of Ilā and was a pious ruler. However, the Mahabharata states that Ila was both his mother and his father. According to the Vishnu Purana, his father was Budha, and he was ancestor of the tribe of Pururavas, from whom descended the Yadavas, Kauravas, and Pandavas of Mahābhārata.
