Bal Gangadhar Tilak started the public Ganapati festival in 1893 to foster nationalist sentiment. He introduced the Shivaji festival to commemorate Shivaji Maharaj and inspire national pride. While the first Shivaji festival is widely cited as having been held in 1895, among the given options, 1896 is the closest year and is sometimes cited as a year of significant early celebration promoted by Tilak.
