Indian nationalist in the context of "Flag of India"

Jawaharlal Nehru (14 November 1889 – 27 May 1964) was an Indian anti-colonial nationalist, secular humanist, social democrat, and statesman who was a central figure in India during the middle of the 20th century. Nehru was a principal leader of the Indian nationalist movement in the 1930s and 1940s. Upon India's independence in 1947, he served as the country's first prime minister for 16 years. Nehru promoted parliamentary democracy, secularism, and science and technology during the 1950s, powerfully influencing India's arc as a modern nation. In international affairs, he steered India clear of the two blocs of the Cold War. A well-regarded author, he wrote books such as Letters from a Father to His Daughter (1929), An Autobiography (1936) and The Discovery of India (1946), that have been read around the world.

The son of Motilal Nehru, a prominent lawyer and Indian nationalist, Jawaharlal Nehru was educated in England—at Harrow School and Trinity College, Cambridge, and trained in the law at the Inner Temple. He became a barrister, returned to India, enrolled at the Allahabad High Court and gradually became interested in national politics, which eventually became a full-time occupation. He joined the Indian National Congress, rose to become the leader of a progressive faction during the 1920s, and eventually of the Congress, receiving the support of Mahatma Gandhi, who was to designate Nehru as his political heir. As Congress president in 1929, Nehru called for complete independence from the British Raj.

Bal Gangadhar Tilak (pronunciation; born Keshav Gangadhar Tilak (pronunciation: [keʃəʋ ɡəŋɡaːd̪ʱəɾ ʈiɭək]); 23 July 1856 – 1 August 1920), endeared as Lokmanya (IAST: Lokamānya), was an Indian nationalist, teacher, and an independence activist. He was one third of the Lal Bal Pal triumvirate. The British colonial authorities called him "The father of the Indian unrest". He was also conferred with the title of "Lokmanya", which means "accepted by the people as their leader". Mahatma Gandhi called him "The Maker of Modern India".

Tilak was one of the first and strongest advocates of Swaraj ('self-rule') and a strong radical in Indian consciousness. He is known for his quote in Marathi: "Swaraj is my birthright and I shall have it!". He formed a close alliance with many Indian National Congress leaders including Bipin Chandra Pal, Lala Lajpat Rai, Aurobindo Ghose, V. O. Chidambaram Pillai and also Muhammad Ali Jinnah who later oversaw Pakistan's independence from British rule.

Sri Aurobindo (born Aurobindo Ghose; 15 August 1872 – 5 December 1950) was an Indian yogi, maharishi, and Indian nationalist. He also edited the newspaper Bande Mataram.

Aurobindo studied for the Indian Civil Service at King's College, in Cambridge, England. After returning to India, he took up various civil service works under the Maharaja of the princely state of Baroda. He became increasingly involved in nationalist politics in the Indian National Congress and the nascent revolutionary movement in Bengal with the Anushilan Samiti. He was arrested in the aftermath of a number of bombings linked to his organisation in a public trial where he faced charges of treason for Alipore Conspiracy and then released, after which he moved to Pondicherry and developed a spiritual practice he called Integral Yoga. He wrote The Life Divine, which deals with the philosophical aspect of Integral Yoga and Synthesis of Yoga, which deals with the principles and methods of Integral Yoga. In 1926, he and Mira Alfassa founded Sri Aurobindo Ashram.
