He emerged as the paramount leader of the Indian independence movement under the tutelage of Mahatma Gandhi and ruled India from its establishment as an independent nation in 1947 until his death in 1964. He is considered to be the architect of the modern Indian nation-state: a sovereign, socialist, secular, and democratic republic. He was also known as Pandit Nehru due to his roots with the Kashmiri Pandit community while many Indian children knew him as "Uncle Nehru" ("Chacha" Nehru)., India held general elections to the 5th Lok Sabha in March 1971 . This was the fifth election since independence in 1947 . The 27 Indian states and union territories were represented by 518 constituencies , each with a single seat . Under the leadership of Indira Gandhi , the Indian National Congress ( R ) led a campaign which focussed on reducing poverty and won a landslide victory , overcoming a split in the party and regaining many of the seats lost in the previous election . During her previous term , there had been internal divisions in the Indian National Congress between Indira Gandhi and the party establishment , especially Morarji Desai . In 1969 , she was expelled from the party , causing a split . Most of the Congress MPs and grassroots support joined Gandhi 's Indian National Congress ( R ) faction , which was recognized by the Election Commission as being the successor to the previous party . 31 MPs who opposed Gandhi became the Indian National Congress ( Organization ) party . Despite the split , the Ruling faction gained votes and seats to win a strong majority , whereas the Organization faction lost half of their seats . On 12 June 1975 , the Allahabad High Court invalidated the result in Gandhi 's constituency on the grounds of electoral malpractices . Instead of resigning , Indira Gandhi called a state of emergency , suspending democracy and outlawed political opposition . After democracy was restored in 1977 , the opposition Congress faction formed a coalition of parties called the Janata Party , which inflicted the Congress ' first electoral defeat ., Indian National Congress (R) was a split in Indian National Congress, created by Indira Gandhi in 1967 when a united opposition, under the banner of Samyukt Vidhayak Dal, won control over several states in the Hindi belt. Indira Gandhi, the daughter of Jawaharlal Nehru, and Congress president, was then challenged by the majority of the party leadership. Initially this party was known as Congress (R), but it soon came to be generally known as the "New Congress". The letter 'R' stands for 'Requisition'. The official party became the Indian National Congress (Organisation) (INC(O)) led by Kamaraj. It was informally called the "Old Congress" and retained the party symbol of a pair of bullocks carrying a yoke.

The house meets in the Lok Sabha Chambers of the Sansad Bhavan in New Delhi., Indira Priyadarshini Gandhi (Nehru; 19 November 1917  31 October 1984) was an Indian politician and central figure of the Indian National Congress party, and to date the only female Prime Minister of India. Indira Gandhi was the daughter of India's first Prime Minister, Jawaharlal Nehru. She served as Prime Minister from 1966 to 1977 and then again from 1980 until her assassination in 1984, making her the second-longest-serving Prime Minister of India after her father. 
Gandhi served as her father's personal assistant and hostess during his tenure as prime minister between 1947 and 1964. She was elected Congress President in 1959. Upon her father's death in 1964, Gandhi refused to enter the Congress party leadership contest and instead chose to become a cabinet minister in the government led by Lal Bahadur Shastri. In the Congress Party's parliamentary leadership election held in early 1966, upon the death of Shastri, she defeated her rival, Morarji Desai, to become leader, and thus succeeded Shastri as Prime Minister of India., Morarji Desai Nishan-e-Pakistan (29 February 1896  10 April 1995) was an Indian independence activist and the Prime Minister of India from 1977 to 1979. He was also the first Prime Minister to head India's first non-Congress Government. He held many important posts in the Government of India such as: Chief Minister of Bombay State, Home Minister, Finance Minister and Deputy Prime Minister of India. On the international scene, Desai holds international fame for his peace activism and made efforts to initiate peace between two rival South Asian states, Pakistan and India. After India's first nuclear explosion in 1974, Desai helped restore friendly relations with China and Pakistan, and vowed to avoid armed conflict such as Indo-Pakistani war of 1971. Domestically, he played a crucial role in the Indian nuclear program after it was targeted by major nuclear powers after conducting a surprise test in 1974. Morarji Desai closed down much of India's premier intelligence agency Research and Analysis Wing (R&AW), and reduced its budget and operations. Desai remains the only Indian national to be conferred with Pakistan's highest civilian award, "Nishan-e-Pakistan", which was conferred on him by President Ghulam Ishaq Khan in 1990 in a colorful ceremony. Later, his policies promoted social, health and administrative reforms in the country. It is rumored that he was a mole of CIA in Indira Gandhi led cabinet.
