Ganesha [SEP] Ganesha Chaturthi
An annual festival honours Ganesha for ten days, starting on Ganesha Chaturthi, which typically falls in late August or early September. The festival begins with people bringing in clay idols of Ganesha, symbolising the god's visit. The festival culminates on the day of Ananta Chaturdashi, when the idols ("murtis") are immersed in the most convenient body of water. Some families have a tradition of immersion on the 2nd, 3rd, 5th, or 7th day. In 1893, Lokmanya Tilak transformed this annual Ganesha festival from private family celebrations into a grand public event. He did so "to bridge the gap between the Brahmins and the non-Brahmins and find an appropriate context in which to build a new grassroots unity between them" in his nationalistic strivings against the British in Maharashtra.
