In North India, Diwali celebrates the return of the epic hero Rama to Ayodhya.
The story comes from the Ramayana. Rama, his wife Sita, and his brother Lakshmana spent 14 years in exile after Rama was banished from the kingdom. During the exile, the demon king Ravana abducted Sita, leading to a major conflict in which Rama defeated Ravana and rescued her.
When Rama, Sita, and Lakshmana finally returned to Ayodhya, residents are traditionally said to have welcomed them by lighting rows of oil lamps. These lamps symbolized joy, guidance, and the victory of dharma—righteous order—over evil. The name Diwali is related to the Sanskrit dipavali, meaning a row or series of lights.
A common mix-up is assuming this story explains Diwali everywhere. Regional traditions differ: some communities associate the festival with Lakshmi, Krishna’s defeat of Narakasura, or other deities and events. In this North Indian Ramayana tradition, however, Rama is the canonical answer.
