Shraddhadeva Manu in the context of "Ila (Hinduism)"

Ikshvaku (Sanskrit Ikṣvāku; Pāli: Okkāka) is a legendary king in Indian religions, particularly Hindu and Jain scriptures. In Hinduism, he is described to be the first king of the Kosala Kingdom, and was one of the ten sons of Shraddhadeva Manu, the first man of the Shraddhadeva Manvantara (7th of the 14 in this Kalpa). He was the founder and first king of the Ikshvaku dynasty, also known as the Suryavamsha, in the kingdom of Kosala, which also historically existed in ancient India. He had a hundred sons, among whom the eldest was Vikukshi. Another son of Ikshvaku's, named Nimi, founded the Kingdom of the Videhas. and Rama are also stated to have belonged to the Suryavamsha or Ikshvaku dynasty.

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.

A manvantara, in Hindu cosmology, is a cyclic period of time identifying the duration, reign, or age of a Manu, the progenitor of mankind. In each manvantara, seven Rishis, certain deities, an Indra, a Manu, and kings (sons of Manu) are created and perish. Each manvantara is distinguished by the Manu who rules/reigns over it, of which we are currently in the seventh manvantara of fourteen, which is ruled by Vaivasvata Manu.
