Diwali, also known as the Festival of Lights, is a major Hindu festival celebrated in India and around the world. It commemorates the return of King Rama to his kingdom of Ayodhya after defeating the demon king Ravana and being exiled for 14 years. Upon his return, people lit lamps and fireworks to celebrate, a tradition that continues today. Diwali involves the lighting of lamps, fireworks, sweets, and is one of the most important festivals in Hinduism.
