Indian nationalism is an instance of territorial nationalism, which is inclusive of all of the people of India, despite their diverse ethnic, linguistic and religious backgrounds. Indian nationalism can trace roots to pre-colonial India, but was fully developed during the Indian independence movement which campaigned for independence from British rule. Indian nationalism quickly rose to popularity in India through these united anti-colonial coalitions and movements. Independence movement figures like Mahatma Gandhi and Jawaharlal Nehru spearheaded the Indian nationalist movement. After Indian Independence, Nehru and his successors continued to campaign on Indian nationalism in face of border wars with both China and Pakistan. After the Indo-Pakistan War of 1971 and the Bangladesh Liberation War, Indian nationalism reached its post-independence peak. However by the 1980s, religious tensions reached a melting point and Indian nationalism sluggishly collapsed in the following decades. Despite its decline and the rise of religious nationalism, Indian nationalism and its historic figures continue to strongly influence the politics of India and reflect an opposition to the sectarian strands of Hindu nationalism and Muslim nationalism.

Jawaharlal Nehru was an Indian anti-colonial nationalist, statesman, secular humanist, social democrat, and author 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, his books written in prison, such as Letters from a Father to His Daughter (1929), An Autobiography (1936) and The Discovery of India (1946), have been read around the world.
