The Ikshvaku dynasty, in Puranic literature, was a mythical dynasty founded by Ikshvaku, grandson of Vivasvan or Surya and son of Vaivasvata Manu. This dynasty is also known as Sūryavaṁśa (the Solar dynasty). The important personalities belonging to this royal house are Harishchandra, Dilīpa, Sagara, Raghu, Rama and Prasenajit. Although, both the Hindu Puranas and the Buddhist texts include Shuddodhana, Gautama Buddha and Rahula in their accounts of the Ikshvaku dynasty, but according to the Buddhist texts, Mahasammata, an ancestor of Ikshvaku was the founder of this dynasty, who was elected by the people as the first king of the present era. The Ikshvaku dynasty of Jaina literature includes 22 Jaina Tirthankaras. According to the Puranas, supreme preceptor of the Ikshvaku dynasty was sage Vashishta.
