The 77th Republic Day theme celebrated 150 years of Vande Mataram, the national song of India composed by Bankim Chandra Chattopadhyay. First published on 7 November 1875, Vande Mataram was later incorporated in the 1882 novel Anandamath and became a rallying cry during the Indian independence movement. The song was first sung at the 1896 session of the Indian National Congress by Rabindranath Tagore. On January 24, 1950, the Constituent Assembly adopted the first two stanzas as the national song. The theme was reflected across the parade's cultural performances and the Ministry of Culture's winning tableau 'Vande Mataram — The Soul Cry of a Nation'. The celebrations connected the song's anti-colonial spirit with modern India's aspirations under 'Atmanirbhar Bharat'.
