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.
The Yadava (Sanskrit: यादव, romanized: yādava, lit. 'descended from Yadu') were an ancient Indian people who believed to have descended from Yadu, a legendary king of Chandravamsha lineage.
The community was formed of various clans, being the Satvatas, Andhakas, Bhojas, Kukuras, Vrishni, Surasenas, and Abhira who all worshipped Krishna. They are listed in ancient Indian literature as the segments of the lineage of Yadu (Yaduvamsha). Amongst the Yadava clans mentioned in ancient Indian literature, the Haihayas are believed to have descended from Sahasrajit, the elder son of Yadu and all other Yadava clans, which include the Chedis, the Vidarbhas, the Satvatas, the Andhakas, the Kukuras, the Bhojas, the Vrishnis and the Surasenas are believed to have descended from Kroshtu or Kroshta, a younger son of Yadu.
Urvashi (Sanskrit: उर्वशी, IAST: Urvaśī) is the most prominent apsara mentioned in the Hindu scriptures like the Vedas, the epics Ramayana and Mahabharata, as well as the Puranas. She is regarded as the most beautiful of all the apsaras, and an expert dancer.
Urvashi has been featured in many mythological events. She emerged out of the thigh of sage Narayana and occupies a special place in the court of Indra, the king of the gods and ruler of svarga. She is famous for her marriage with Pururavas, the first king of the legendary Chandravansha, whom she later abandoned. She also plays a significant part in the birth of Vashishtha and Agastya, two of the most revered sages in Hinduism. Urvashi's story has been an inspiration for various arts, performances and literature. The poet Kalidasa (fl. 4th -5th century CE) has adapted Urvashi and Pururavas as the main characters in his play Vikramorvashiyam.
