Jawaharlal Nehru was born on 14 November 1889 in Allahabad in British India. His father, Motilal Nehru (1861-1931), a wealthy barrister who belonged to the Kashmiri Pandit community, served twice as President of the Indian National Congress during the Independence Struggle. His mother, Swaruprani Thussu (1868-1938), who came from a well–known Kashmiri Brahmin family settled in Lahore, was Motilal's second wife, the first having died in child birth. Jawaharlal was the eldest of three children, two of whom were girls.The elder sister, Vijaya Lakshmi, later became the first female president of the United Nations General Assembly.The youngest sister, Krishna Hutheesing, became a noted writer and authored several books on her brother.

Nehru married Kamala Kaul in 1916. Their only daughter Indira was born a year later in 1917. (Kamala gave birth to a boy in November 1924, but he was premature and died 2 days later.)
Nehru was alleged to have had relationships with Padmaja Naidu and Edwina Mountbatten. Edwina's daughter Pamela acknowledged Nehru's platonic affair with Edwina
As India's first Prime minister and external affairs minister, Jawaharlal Nehru played a major role in shaping modern India's government and political culture along with sound foreign policy. He is praised for creating a system providing universal primary education, reaching children in the farthest corners of rural India. Nehru's education policy is also credited for the development of world-class educational institutions such as the All India Institute of Medical Sciences, Indian Institutes of Technology, and the Indian Institutes of Management. "Nehru was a great man... Nehru gave to Indians an image of themselves that I don't think others might have succeeded in doing." – Sir Isaiah Berlin.
In addition, Nehru's stance as an unfailing nationalist led him to also implement policies which stressed commonality among Indians while still appreciating regional diversities. This proved particularly important as post-Independence differences surfaced since British withdrawal from the subcontinent prompted regional leaders to no longer relate to one another as allies against a common adversary. While differences of culture and, especially, language threatened the unity of the new nation, Nehru established programs such as the National Book Trust and the National Literary Academy which promoted the translation of regional literatures between languages and also organized the transfer of materials between regions. In pursuit of a single, unified India, Nehru warned, "Integrate or perish."
In his lifetime, Jawaharlal Nehru enjoyed an iconic status in India and was widely admired across the world for his idealism and statesmanship. His birthday, 14 November, is celebrated in India as Baal Divas ("Children's Day") in recognition of his lifelong passion and work for the welfare, education and development of children and young people. Children across India remember him as Chacha Nehru (Uncle Nehru). Nehru remains a popular symbol of the Congress Party which frequently celebrates his memory. Congress leaders and activists often emulate his style of clothing, especially the Gandhi cap and the "Nehru Jacket", and his mannerisms. Nehru's ideals and policies continue to shape the Congress Party's manifesto and core political philosophy. An emotional attachment to his legacy was instrumental in the rise of his daughter Indira to leadership of the Congress Party and the national government.
Nehru's personal preference for the sherwani ensured that it continues to be considered formal wear in North India today; aside from lending his name to a kind of cap, the Nehru jacket is named in his honour due to his preference for that style.
Numerous public institutions and memorials across India are dedicated to Nehru's memory. The Jawaharlal Nehru University in Delhi is among the most prestigious universities in India. The Jawaharlal Nehru Port near the city of Mumbai is a modern port and dock designed to handle a huge cargo and traffic load. Nehru's residence in Delhi is preserved as the Teen Murti House now has Nehru Memorial Museum and Library, and one of five Nehru Planetariums that were set in Mumbai, Delhi, Bangalore, Allahabad and Pune. The complex also houses the offices of the 'Jawaharlal Nehru Memorial Fund', established in 1964 under the Chairmanship of Dr S. Radhakrishnan, then President of India. The foundation also gives away the prestigious 'Jawaharlal Nehru Memorial Fellowship', established in 1968. The Nehru family homes at Anand Bhavan and Swaraj Bhavan are also preserved to commemorate Nehru and his family's legacy.
Many documentaries about Nehru's life have been produced. He has also been portrayed in fictionalised films. The canonical performance is probably that of Roshan Seth, who played him three times: in Richard Attenborough's 1982 film Gandhi, Shyam Benegal's 1988 television series Bharat Ek Khoj, based on Nehru's The Discovery of India, and in a 2007 TV film entitled The Last Days of the Raj. In Ketan Mehta's film Sardar, Nehru was portrayed by Benjamin Gilani. Girish Karnad's historical play, Tughlaq (1962) is an allegory about the Nehruvian era. It was staged by Ebrahim Alkazi with National School of Drama Repertory at Purana Qila, Delhi in 1970s and later at the Festival of India, London in 1982.
Nehru was a prolific writer in English and wrote a number of books, such as The Discovery of India, Glimpses of World History, and his autobiography, Toward Freedom.
In 1955 Nehru was awarded Bharat Ratna, India's highest civilian honour.

Nehru was also a renowned bridge player.
