Input: Question: In what country was the dynasty based which Dasharatha ruled as king? Passage:Dasharatha was the king of Ikshvaku dynasty who ruled Ayodhya. He had four princes Rama, Lakshmana, Bharata and Shatrughna. Janaka ruled Videha. His daughter Sita was married to Rama. Sita was kidnapped by Ravana, who took her to his kingdom Lanka. During the search for Sita, Rama and Lakshmana meet Sugriva and Hanuman. Sugriva, the king of Vanara clan was removed from his throne of Kiskindha by his brother Vali(He later become Jain Monk and attained Moksha). Rama and Lakshmana helped Sugriva get back his kingdom. They, along with the army of Sugriva marched towards Lanka. Vibhishana, Ravana's brother tried to persuade him to return Sita. However, Ravana did not agree. Vibhishana allied with Rama. There was a war fought between the armies of Rama and Ravana. Lakshmana kills Ravana in the end(deviating from the Ramayana where the hero Rama slays Ravana) and Vibhishana becomes the king of Lanka. Rama and Lakshmana return to Ayodhya. Rama had around eight thousand wives among whom Sita was the principle consort(in the Hindu epic , Rama has only one wife Sita), where as Lakshmana had around sixteen thousand wives in which Prithvisundari was his principle consort(in the Hindu epic, he had only one wife, Urmila). After Lakshmana's death, Rama becomes a monk. He attains Kevala Jnana and subsequently moksha. Lakshmana and Ravana, on the other hand, go to hell. Sita was born in heaven.
