Mahabali is a legendary king in Hindu mythology, particularly revered in the state of Kerala, India. He is known for his immense generosity and fairness, ruling over a prosperous kingdom where his subjects were happy and content. His reign is often associated with the festival of Onam, which celebrates his annual visit to his people. According to the myth, Mahabali was granted a boon by Lord Vishnu to visit his kingdom once a year after being defeated by Vamana, the fifth avatar of Vishnu. During his visit, people celebrate with feasts, traditional dances, and floral decorations, symbolizing the joy and abundance of his rule.
