The Legend of King Mahabali and Onam

The story of Onam is deeply rooted in Hindu mythology.
King Mahabali, also known as Maveli, was a beloved and just ruler of Kerala. His reign was marked by prosperity, equality, and happiness. Fearing his growing influence, the gods sought the help of Lord Vishnu, who appeared as Vamana (a dwarf Brahmin).
When Mahabali offered land, Vamana expanded into a cosmic form—covering the earth and sky in two steps. With no land left, Mahabali offered his head, and Vishnu sent him to the underworld. Moved by his devotion, Vishnu granted him permission to return once a year, which is celebrated as Onam.
