When we think of Kerala, we think of beautiful backwaters, rich culture, and vibrant festivities. Lovingly called God’s Own Country, Kerala is located in the southern part of India. Its grand festival, Onam, is admired far beyond the state’s boundaries. In fact, it is one of those festivals that brings people across India together in the spirit of joy, prosperity, and togetherness.
Most of us know Onam as Kerala’s famous 10-day harvest festival. But today, thanks to social media, people across the country get to witness its grand celebrations and understand the deeper meaning behind the festival. That shows it’s not just the colourful pookalams, vibrant decorations, and traditional feasts.
Meaning and Origin of Onam
The word ‘Onam’ is derived from the Sanskrit word ‘Shravanam‘, which is known as ‘Thiruvonam’ in Malayalam. Thiruvonam is one of the 27 Nakshatras (lunar constellations) in Vedic astrology and is associated with Lord Vishnu.
The festival is celebrated when the Thiruvonam Nakshatra occurs during Chingam, the first month of the Malayalam calendar. This combination is considered highly auspicious and marks a period of abundance, gratitude, and fresh beginnings.

History and the Legend of King Mahabali
Onam marks the annual homecoming of the legendary King Mahabali (Maveli). A wise and generous ruler whose reign is remembered as an era of equality, peace, and prosperity.
According to Hindu mythology, Lord Vishnu appeared as Vamana, his fifth incarnation, and sent Mahabali to the netherworld after granting him a boon to visit his people once every year.
It is believed that Onam marks this yearly visit of King Mahabali, and people welcome him by decorating their homes with floral rangoli (Pookalam), preparing the grand Onam Sadya, wearing traditional attire, and participating in cultural celebrations.
