Significance
Onam is the grand harvest festival of Kerala, celebrating the annual homecoming of the legendary and beloved King Mahabali to visit his people. A ten-day festival of abundance, unity and Kerala's cultural heritage, it transcends caste and creed and is marked by flower carpets, grand feasts, boat races and folk arts, honouring a golden age of prosperity and equality.
The story
Mahabali (Maveli) was a noble and generous asura king under whose just rule Kerala enjoyed a golden age of equality and plenty. Alarmed by his growing power, the gods sent Vishnu in his dwarf avatar, Vamana, who begged three paces of land. When the king granted it, Vamana grew cosmic in size, covering the earth and sky in two strides, and for the third placed his foot on Mahabali's head, pushing him to the netherworld. Honouring the king's devotion, Vishnu granted him an annual visit to his people — and Onam celebrates that homecoming.
