Ikshvaku (Sanskrit: इक्ष्वाकु "Sugarcane", pāli: Okkāka) was the first king of the Ikshvaku dynasty and founder of the Solar Dynasty of Kshatriyas in Vedic civilization in ancient India.
Ikshvaku was the first King to implement the Manusmriti, or the religious rules of Hindu living composed through divine inspiration and from the Vedas by his father. He is remembered in Hindu scriptures as a righteous and glorious king. In some versions, he is the son of Vaivasvata Manu (formerly the Emperor Satyavrata of Dravida), one of the two central characters along with the Lord Matsya incarnation of Lord Vishnu in the Matsya Purana. He is born to Manu after the deluge which sends the King's ship to the top of the Malaya Mountains in the Dravida country.
