He was the proponent of liberty as the ultimate ideal. Savarkar was a poet, writer and playwrighter. He launched a movement for religious reform advocating dismantling the system of caste in Hindu culture, and reconversion of the converted Hindus back to Hindu religion. Savarkar created the term Hindutva, and emphasized its distinctiveness from Hinduism which he associated with social and political disunity. Savarkar’s Hindutva sought to create an inclusive collective identity. The five elements of Savarkar's philosophy were Utilitarianism, Rationalism and Positivism, Humanism and Universalism, Pragmatism and Realism.

Savarkar's revolutionary activities began when studying in India and England, where he was associated with the India House and founded student societies including Abhinav Bharat Society and the Free India Society, as well as publications espousing the cause of complete Indian independence by revolutionary means. Savarkar published The Indian War of Independence about the Indian rebellion of 1857 that was banned by British authorities. He was arrested in 1910 for his connections with the revolutionary group India House. Following a failed attempt to escape while being transported from Marseilles, Savarkar was sentenced to two life terms amounting to 50 years' imprisonment and moved to the Cellular Jail in the Andaman and Nicobar Islands.

Lata Mangeshkar (born September 28, 1929) is a singer from India. She is one of the best-known and most respected playback singers in India. Mangeshkar's career started in 1942 and has spanned over six and a half decades. She has recorded songs for over a thousand Hindi films and has sung songs in over thirty-six regional Indian languages and foreign languages, though primarily in Hindi. She is the elder sister of singer Asha Bhosle, Hridayanath Mangeshkar, Usha Mangeshkar and Meena Mangeshkar. She is the second vocalist to have ever been awarded the Bharat Ratna, India's highest civilian honour.

Mangeshkar was featured in the Guinness Book of World Records from 1974 to 1991 for having made the most recordings in the world. The claim was that she had recorded approximately 25,000 solo, duet, and chorus-backed songs in 20 Indian languages between 1948 to 1974. Over the years, while several sources have supported this claim, others have raised concerns over its veracity, claiming that this number was highly exaggerated and that Mangeshkar's younger sister, Asha Bhosle, had more song recordings than she had. In 2011 Guinness officially acknowledged Bhosle as the most recorded artist in music history.
