History
According to Hindu mythology, King Mahabali was a generous and just ruler who commanded great respect from his subjects. However, the gods became jealous of his popularity, and Lord Vishnu took the form of the Vamana avatar to trick Mahabali and banish him to the netherworld. Before leaving, Mahabali was granted a boon to visit his kingdom once a year, which is celebrated as Onam24.
