Lokmanya Tilak, born as Keshav Gangadhar Tilak (23 July 1856 – 1 August 1920), was an Indian nationalist, journalist, teacher, social reformer, lawyer and independence fighter who was the first popular leader of the Indian Independence Movement. The British colonial authorities derogatorily called him “Father of the Indian unrest”. Tilak professed a different ethics from that of Gandhi and followed a trend of extremism and violence, which earned him the appellation of the ‘father of Indian unrest’. He advocated ‘violence as the higher duty’ based on his interpretation of the Bhagavad-Gita (‘Song of the Lord’).
