Ayodhya
Srimad-Bhagavatam
SB Canto 1
SB 1.12.19, Purport:
Lord Rāma: The Supreme Personality of Godhead incarnated Himself as Śrī Rāma, accepting the sonhood of His pure devotee Mahārāja Daśaratha, the King of Ayodhyā. Lord Rāma descended along with His plenary portions, and all of them appeared as His younger brothers. In the month of Caitra on the ninth day of the growing moon in the Tretā-yuga, the Lord appeared, as usual, to establish the principles of religion and to annihilate the disturbing elements.
