Ikshvaku इक्ष्वाकु

What the word means

Ikshvaku is the name of a king, and of the royal family descended from him. According to the Ramayana, Ikshvaku was the son of Manu and the first king of Ayodhya; every king of that city after him is “an Ikshvaku”. Rama is introduced in the very first sarga as “born in the line of Ikshvaku” (Bala Kanda 1.1.8), and the poem calls him and his family by the founder’s name hundreds of times. Two other names in the poem come from the same family tree: Rama is Kakutstha, a descendant of King Kakutstha, and Raghava, a descendant of King Raghu.

What Valmiki’s text says

The fullest account comes at Rama’s wedding in Mithila. When the two royal houses meet, Dasharatha asks his family priest Vasishtha to speak, since in a royal marriage the bridegroom’s lineage must be declared. Vasishtha begins at creation (Bala Kanda 1.70.19): from the unmanifest came Brahma; from Brahma, Marichi; from Marichi, Kashyapa; from Kashyapa, Vivasvat, the sun; and from Vivasvat, Manu (1.70.20). “Manu was the first Prajapati, and Ikshvaku was Manu’s son. Know that Ikshvaku was the first king in Ayodhya” (1.70.21).

Then the names roll on, father to son: Kukshi, Vikukshi, Bana, Anaranya, Prithu, Trishanku, Dhundhumara, Yuvanashva, Mandhata, Susandhi, Dhruvasandhi, an earlier Bharata, and Asita. Asita is driven into exile by enemy kings and dies in the Himalaya; one of his pregnant wives poisons the other, and the child is born “together with the poison” (gara), so he is named Sagara (1.70.37). After him come Asamanja, Amshuman, Dilipa and Bhagiratha; then Kakutstha and Raghu; then Kalmashapada, who became a man-eater (1.70.39-40); and on through Shankhana, Sudarshana, Agnivarna, Shighraga, Maru, Prashushruka, Ambarisha, Nahusha, Yayati, Nabhaga and Aja, to Dasharatha, and from Dasharatha, “the brothers Rama and Lakshmana” (1.70.43). Vasishtha closes by asking for Janaka’s daughters for the two princes, “born in the Ikshvaku line of kings pure from the first line” (1.70.44).

Many of these names are already familiar by this point, because Vishvamitra has told their stories on the road. Sagara and his sixty thousand sons, Amshuman, Dilipa and Bhagiratha’s bringing down of the Ganga fill Bala Kanda 38 to 44. Trishanku, “increaser of the Ikshvaku line”, who wanted to go to heaven in his body, is the subject of sargas 57 to 60 (1.57.10). King Ambarisha’s sacrifice and the boy Shunahshepa come in sargas 61 and 62. Even the kings of Vishala are Ikshvakus, descended from Ikshvaku’s son Vishala (1.47.11).

The line is recited a second time in the Ayodhya Kanda, when Vasishtha tries to persuade Rama to return from exile (Ayodhya Kanda 2.110). There he adds why the names matter: Kakutstha is the one “by whom the Kakutsthas are known”, and Raghu the one “from whom come the Raghavas” (2.110.25). And he states the family’s rule: “among all the Ikshvakus the firstborn becomes king” (2.110.33). This second list differs in small ways from the first; for example, it gives Nabhaga as Nahusha’s son without Yayati between them, and names Suvrata as Aja’s brother. Such small differences are normal in old recited genealogies.

The poem opens its story by placing itself inside this family: “In the line of these great-souled Ikshvaku kings arose this great tale, known as the Ramayana” (1.5.3), and Ayodhya is a city “built by Manu himself” (1.5.6).

Where it comes from

Ikshvaku is an ancient name. He is mentioned once in the Rigveda, in a hymn of its tenth book, as a rich and prosperous figure, and later Vedic texts know kings called Aikshvaka, “of Ikshvaku’s line”. The Puranas, such as the Vishnu Purana and the Bhagavata Purana, give long lists of this dynasty, which they call the solar line (surya-vamsha) because it descends from Vivasvat, the sun; their lists are longer than Valmiki’s and differ in many names. The name is not limited to Hindu texts: early Buddhist texts trace the Buddha’s Shakya clan back to King Okkaka, the Pali form of Ikshvaku, and Jain tradition places its first tirthankara, Rishabhanatha, in the Ikshvaku line. Kalidasa’s Raghuvamsha, much later than the Ramayana, is a whole poem about the kings of this family.

Why it matters in the story

The Ikshvaku line is the backdrop for everything Rama does. He is measured against ancestors who kept their word, dug the ocean, brought down the Ganga and won heaven by austerity, and also against ancestors who fell. The family rule that the eldest inherits is exactly what Kaikeyi’s boons overturn, and it is what Bharata and Vasishtha appeal to when they beg Rama to return. Readers often see Rama’s choice to honour his father’s word over his own right as the line’s highest moment: he keeps the family’s name by giving up the family’s throne.
