Besides the festivity of the celebration, there is a deeper meaning of prosperity, equality, unity and culture of Kerala.
History and Mythological Significance of Onam 2026
According to mythology, the Onam festival relates to King Mahabali. This legendary monarch was known as generous, wise and devoted to his subjects. In particular, during the reign of Mahabali people lived prosperous and happy.
However, as Mahabali’s reputation kept spreading among the gods who were afraid of his rising power and asked for help from Lord Vishnu. Vishnu appeared before Mahabali in the figure of Vamana – a dwarf Brahmin.
Mahabali gave all the lands that Vamana could cover with three steps. In order to accomplish the wish of the king, Vishnu took a colossal size and took possession of the whole earth in one step, and the sky in the other. Mahabali had nothing to give the last step and offered his head.
Vishnu put his foot on the king’s head and sent him to hell. However, appreciating Mahabali’s devotion and generosity, Vishnu gave him the privilege to return to earth once a year.
Traditionally, Onam is related to this annual return of King Mahabali.
Why Is Onam Celebrated?
Onam has its roots as a traditional harvest festival dedicated to prosperity and abundance. Moreover, it serves as an occasion for the reunion of family members who come to their relatives bringing food, taking part in various rites and playing.
This festival is celebrated in all communities regardless of religion or social status of a person, which makes Onam an important part of Kerala culture.
Pookalam is one of the most characteristic rituals of this holiday. It represents a floral design made by the family at home. Each following day of the ten days festival is marked by the addition of more flowers.
