Story behind Onam celebration:
King Mahabali, a wise ruler of Kerala, was renowned for his prosperous and egalitarian rule. Lord Vishnu, concerned about Mahabali’s growing popularity, tested his humility in the form of a dwarf Brahmin, Vamana. Despite his immense generosity, Vamana grew to cover the earth and heavens, leading to Mahabali’s selfless offer of his head. Impressed by Mahabali’s devotion, Lord Vishnu granted him an annual visit to his kingdom, celebrated as Onam.
