Lokmanya Tilak and the Demand for Swaraj
Bal Gangadhar Tilak was born on July 23, 1856, at Ratnagiri in present-day Maharashtra. He became one of the earliest and strongest advocates of Swaraj, or self-rule, during India’s freedom struggle.
Tilak used education, journalism and public mobilisation to widen political awareness. He was associated with the Marathi newspaper Kesari and the English newspaper The Mahratta. His declaration that Swaraj was his birthright became one of the best-known calls of the national movement.
He also helped transform Ganesh celebrations into a public platform and promoted the public commemoration of Shivaji as methods of bringing political discussion beyond small elite circles. Tilak was one of the leaders remembered through the phrase Lal–Bal–Pal, along with Lala Lajpat Rai and Bipin Chandra Pal.
