History & Significance of Onam

history and significance of Onam.

The Onam festival honours King Mahabali, who, as per Hindu mythology, ruled with kindness and fairness. When Lord Vishnu, in the form of Vamana, asked for three paces of land, he covered the universe in two steps, and Mahabali offered his head for the third. Impressed by his humility, the Lord allowed him to visit his people once a year. Onam marks his homecoming, celebrated with feasts and festivities across the state.

The festival has been celebrated in Kerala for centuries, with the earliest mentions found as far back as the 3rd century in Tamil Literature. Here, it is described as a grand festival with feasts, games, and temple offerings. This makes Onam one of the oldest festivals still celebrated in India. Among its many highlights is the thrilling snake boat race, or Vallamkali, which began in the 13th century as contests between rival kingdoms on Kerala’s backwaters and continues today as a vibrant celebration of tradition, rhythm, energy, and teamwork.

The best place to witness this grand celebration is Tripunithura town near Kochi, where the historic Athachamayam procession takes over the streets every year.

2. Vallamkali– The Snake Boat Race

Vallamkali is the famous snake boat race of Onam.

Vallamkali is Kerala’s famous snake boat race, held on the Pampa River. During the race, the river bursts into life with the beat of drums and the cheers of the crowd. Long, narrow boats with over a hundred rowers glide through the water like snakes, moving in perfect rhythm. The Aranmula Uthrattathi Boat Race in Pathanamthitta and the Nehru Trophy Race on Alleppey’s Punnamada Lake are the most popular ones to watch. If you want to feel the thrill up close, Alleppey is the place to be.

Pulikali, meaning “the play of the tiger”, is one of Onam’s most colourful events. During the festival, hundreds of men paint themselves as tigers and dance to the loud beats of drums. It’s wild, energetic, and full of fun – a sight you’ll never forget. The best place to experience Pulikali is Thrissur, where thousands of people gather at Swaraj Round (Thekkinkadu Maidanam) to watch this unique street spectacle. 

4. Pookalam: The Floral Rangoli

Onam is also called the festival of flowers, and Pookalam is the heart of it. Every morning during the Onam festival, families create beautiful flower rangolis in their door fronts or temples as a ritual, which look like flower mats. Each day, new petals are added, making the designs bigger and brighter. Wherever you walk, the streets are alive with the colours and fragrance of these floral carpets. To see the most stunning and elaborate Pookalam designs, visit Thrissur or Kochi, especially at temples like Thrikkakara Temple, where grand competitions are held.

5. Kasavu Saree– Kerala’s Traditional Pride

During Onam, women of all ages, from little girls to grandmothers, wear the Kasavu saree, an off-white saree with a golden border. Simple yet royal, it is a proud symbol of Kerala’s culture. Seeing everyone dressed in it, you might feel like getting one yourself. And if you ask a local where to buy it, they’ll gladly guide you with a warm smile. For the most authentic ones, head to Kuthampully village in Thrissur district, famous for handwoven Kasavu sarees, or explore big textile stores in Kochi and Thiruvananthapuram.
