Period

Some cultural evidence (the presence of sati in the Mahabharata but not in the main body of the Ramayana) suggests that the Ramayana predates the Mahabharata.However, the general cultural background of the Ramayana is one of the post-urbanization period of the eastern part of North India (c. 450 BCE), while the Mahabharata reflects the Kuru areas west of this, from the Rigvedic to the late Vedic period.

By tradition, the epic belongs to the Treta Yuga, one of the four eons (yuga) of Hindu chronology. Rama is said to have been born in the Treta Yuga to King Daśaratha in the Ikshvaku vamsa (clan).

The names of the characters (Rama, Sita, Dasharatha, Janaka, Vasishta, Vishwamitra) are all known in Vedic literature such as the Brahmanas which are older than the Valmiki Ramayana. However, nowhere in the surviving Vedic poetry is a story similar to the Ramayana of Valmiki. According to the modern academic view, Brahma, one of the main characters of Ramayana, and Vishnu, who according to Bala Kanda was incarnated as Rama, are not Vedic deities, and come first into prominence with the epics themselves and further during the 'Puranic' period of the later 1st millennium CE. There is also a version of Ramayana, known as Ramopakhyana, found in the epic Mahabharata. This version, depicted as a narration to Yudhishtira, does not accord divine characteristics to Rama.

There is general consensus that books two to six form the oldest portion of the epic while the first book Bala Kanda and the last the Uttara Kanda are later additions. The author or authors of Bala Kanda and Ayodhya Kanda appear to be familiar with the eastern Gangetic basin region of northern India and the Kosala and Magadha region during the period of the sixteen janapadas as the geographical and geopolitical data is in keeping with what is known about the region. However, when the story moves to the Aranya Kanda and beyond, it seems to turn abruptly into fantasy with its demon-slaying hero and fantastic creatures. The geography of central and South India is increasingly vaguely described. The knowledge of the location of the island of Sri Lanka also lacks detail. Basing his assumption on these features, the historian H.D. Sankalia has proposed a date of the 4th century BC for the composition of the text. A. L. Basham, however, is of the opinion that Rama may have been a minor chief who lived in the 8th or the 7th century BC
