History of Onam Festival & King Mahabali

There is an ancient Onam story associated with this vibrant festival of the south. The history of Onam is connected with King Mahabali, the golden era of his reign, and his connection to the Vamana Avatar.

Let us explain the story of King Mahabali, also called “Maveli” and “Onathappan”, and what makes this generous emperor an integral part of Onam celebrations!

Who was Mahabali?

Mahabali was originally born in a demon family and was a keen devotee of Lord Vishnu. Sensible and vigilant, King Mahabali was a popular Asura emperor who ruled ancient Kerala.

Under his monarchy, equality flourished in Kerala, financial and racial discrimination vanished completely, and corruption and crime ratio dropped to zero. People were happy and content.

Courtesy of his strength of character and courage, the public gave him the title of “Mahabali”, meaning the king of kings! Even his son, Bana, lived on to become a generous king following in his father’s footsteps.

The envy of the gods

The gods were envious of Mahabali’s increasing fame and popularity. As a means to overpower Mahabali, Aditi, the mother of the gods, sought the help of Lord Vishnu himself.

Lord Vishnu decided to put the king’s generosity and kindness to test, masking himself as a needy dwarf brahmin named Vamana. He appeared before Mahabali right before the king’s daily ritual of donating aid to Brahmins.

Lord Vishnu in Vamana Avatar

Camouflaged as Vamana, Lord Vishnu pretended to be a pitiable Brahmin and requested for some portion of land from Mahabali.

He specifically requested for a piece of land that would be covered in three footsteps. The generous king was bewildered but agreed to give him his desired land.

Shukracharya, Mahabali’s wise advisor, cautioned the king against it. But the king was not one to break his promise!

In an instant, Vamana expanded his body to galactic proportions, covering the earth in the first step and the skies in the second, before asking the emperor where he should step next.

When Mahabali realized his next step would destroy the planet, he decided to sacrifice himself. He requested the brahmin, with folded hands and bowed head, to put his third step on his head instead.

Vamana stepped on the emperor’s head, driving him into ‘Patala’, or the underworld, before disclosing his true self as Lord Vishnu. He told Mahabali about his intention to simply test the king and offered to reward him for passing the test gracefully!

Mahabali’s annual visit

The kind ruler was extremely attached to his empire and his people, so he requested to be permitted to come to his kingdom once every year. Lord Vishnu was greatly moved by the king’s nobility and granted his wish.

Lord Vishnu blessed him and said he would be immortal in the hearts of Lord Vishnu as well as the people of his own kingdom.

So, it is said that every year without fail, King Mahabali visits the land of Kerala and the locals honor his presence with the grand festival of Onam!
