History and Origin of Onam – The Harvest Festival of Kerala

Onam is the harvest festival of Kerala, celebrated to commemorate and honour the return of demon king known as Mahabali or Maveli to his state. According to mythology, King Mahabali ruled all three kingdoms of the world after triumphing over the Gods. Due to his kind, loving , and generous nature, King Mahabali was quite renowned among the people. Annoyed by the popularity of King Mahabali, the Gods went to Lord Vishnu to seek his help. Lord Vishnu visited King Mahabali in the form of a Brahmin dwarf, Vamana.

King Mahabali promised Vamana he would fulfill all his wishes, to which Vamana replied that he wants three pieces of land. In the first and second steps, Vamana rose in size, covering the sky and the Netherworld. He was about to take the third step when King Mahabali offered Vamana his head.


Impressed by his generosity and sacrifice, Lord Vishnu granted a boon to King Mahabali to rule his kingdom till the end of Kalyuga, and visit the people of his beloved state during Onam. This is the reason people of Kerala celebrate Onam.

During Onam, the people of Kerala construct and spread floral carpets known as Pookkalam in front of their houses to welcome King Mahabali.
