Ganesh Chaturthi is celebrated as the birth anniversary of Ganesha on the fourth day of Bhadra (August/September) in the states of Maharashtra, Andhra Pradesh, Tamil Nadu, Karnataka and many other parts of India. Lord Ganesha is the god of wisdom and prosperity and is invoked before the beginning of any auspicious work by the Hindus. According to mythology Lord Ganesha, the elephant-headed god, is the son of Lord Shiva and Parvati, brother of Lakshmi, Saraswati and Kartikeya, the general of the gods. Ganesh Chaturthi was started by Shivaji to promote culture and nationalism, the festival was revived by Lokmanya Bal Gangadhar Tilak to spread the message of freedom struggle and to defy the British, who had banned public assemblies. During the Chaturthi or the last day, thousands of processions carrying idols of Ganesha converge on the lakes, rivers and seas for the visarjan or immersion, accompanied by drum-beats, devotional songs, dancing and chanting of "Ganpati bappa morya". The festival ends with pleas to Lord Ganesha
to return the next year.
