The Athachamayam celebrations are traditionally preceded by a series of rituals held over three days. One of the ceremonial highlights is the arrival of the royal messenger, who rides into the town on an elephant, beats a traditional drum to gather the people, and formally announces the commencement of the festivities. Reflecting Kerala's long-standing spirit of communal harmony, representatives from different religious communities—including the priest of the Kakkattu Temple, the Nettur Thangal, and the priest of Karingachira—pay ceremonial respects to the king on the day of the procession. Dressed in elaborate royal attire, adorned with the traditional Veeralipattu ornaments and a golden crown, the king symbolically begins the grand procession by entering the royal palanquin. The celebrations conclude with a traditional Onasadya feast and a ceremony honoring individuals who have made notable contributions to the local community.
Several legends are associated with the origins of Athachamayam, adding to its historical and cultural significance. One popular tradition connects the festival with the Thrikkakara Vamana Moorthy Temple, where it is believed that the early celebrations were organized with the participation of numerous regional rulers. According to this belief, the procession was led jointly by the Maharaja of Cochin and the rulers known as the Samoothiris. Another local tradition links the festival to historic conflicts between the Cochin kingdom and the Samoothiris over territorial control. Some historical interpretations also suggest that the procession commemorates a significant military victory achieved by the Cochin ruler.
Today, Athachamayam serves as more than a royal pageant. It is a vibrant celebration of Kerala's cultural identity, preserving memories of its royal heritage while promoting unity, inclusiveness, and respect for diverse traditions. Every year, the festival brings together artists, performers, residents, and visitors to celebrate the enduring spirit of Onam and the rich cultural legacy of the state.
