The country became an independent nation within the British Commonwealth on 15 August 1947. Concurrently the Muslim - majority northwest and east of British India was separated into the Dominion of Pakistan, by the partition of India. The partition led to a population transfer of more than 10 million people between India and Pakistan and the death of about one million people. Indian National Congress leader Jawaharlal Nehru became the first Prime Minister of India, but the leader most associated with the independence struggle, Mahatma Gandhi, accepted no office. The new constitution of 1950 made India a secular and a democratic state. The nation faced religious violence, casteism, naxalism, terrorism and regional separatist insurgencies, especially in Jammu and Kashmir and northeastern India. India has unresolved territorial disputes with China, which in 1962 escalated into the Sino - Indian War, and with Pakistan, which resulted in wars in 1947, 1965, 1971 and 1999. India was neutral in the Cold War, but purchased its military weapons from the Soviet Union, while its arch - foe Pakistan was closely tied to the United States and the People 's Republic of China. India is a nuclear - weapon state, having conducted its first nuclear test in 1974, followed by another five tests in 1998. From the 1950s to the 1980s, India followed socialist - inspired policies. The economy was shackled by extensive regulation, protectionism and public ownership, leading to pervasive corruption and slow economic growth. Beginning in 1991, neoliberal economic reforms have transformed India into the third largest and one of the fastest - growing economies in the world, though corruption remains a pervasive problem. Today, India is a major world power with a prominent voice in global affairs and is seeking a permanent seat in the United Nations Security Council. Many economists, military analysts and think tanks expect India to become a superpower in the near future.

Credit for the political integration of India is largely attributed to Vallabhbhai Patel ( deputy Prime Minister of India at the time ), who post-independence and before the death of Mahatma Gandhi teamed up with Jawaharlal Nehru and the Mahatma to ensure that the constitution of independent India would be secular. Partition of India Main article : Partition of India A group photo of people accused in Gandhi 's murder case. Standing : Shankar Kistaiya, Gopal Godse, Madanlal Pahwa, Digambar Badge ( Approver ). Sitting : Narayan Apte, Vinayak D. Savarkar, Nathuram Godse, Vishnu Karkare. An estimated 3.5 million Hindus and Sikhs living in West Punjab, North - West Frontier Province, Baluchistan, East Bengal and Sind migrated to India in fear of domination and suppression in Muslim Pakistan. Communal violence killed an estimated one million Hindus, Muslims and Sikhs, and gravely destabilised both dominions along their Punjab and Bengal boundaries, and the cities of Calcutta, Delhi and Lahore. The violence was stopped by early September owing to the co-operative efforts of both Indian and Pakistani leaders, and especially due to the efforts of Mohandas Gandhi, the leader of the Indian freedom struggle, who undertook a fast - unto - death in Calcutta and later in Delhi to calm people and emphasise peace despite the threat to his life. Both governments constructed large relief camps for incoming and leaving refugees, and the Indian Army was mobilised to provide humanitarian assistance on a massive scale. The assassination of Mohandas Gandhi on 30 January 1948 was carried out by Nathuram Vinayak Godse, a Hindu nationalist, who held him responsible for partition and charged that Mohandas Gandhi was appeasing Muslims. More than one million people flooded the streets of Delhi to follow the procession to cremation grounds and pay their last respects. In 1949, India recorded almost 1 million Hindu refugees into West Bengal and other states from East Pakistan, owing to communal violence, intimidation and repression from Muslim authorities. The plight of the refugees outraged Hindus and Indian nationalists, and the refugee population drained the resources of Indian states, who were unable to absorb them. While not ruling out war, Prime Minister Nehru and Sardar Patel invited Liaquat Ali Khan for talks in Delhi. Although many Indians termed this appeasement, Nehru signed a pact with Liaquat Ali Khan that pledged both nations to the protection of minorities and creation of minority commissions. Although opposed to the principle, Patel decided to back this pact for the sake of peace, and played a critical role in garnering support from West Bengal and across India, and enforcing the provisions of the pact. Khan and Nehru also signed a trade agreement, and committed to resolving bilateral disputes through peaceful means. Steadily, hundreds of thousands of Hindus returned to East Pakistan, but the thaw in relations did not last long, primarily owing to the Kashmir dispute. Integration of princely states Main article : Political integration of India Political integration of India Sardar Vallabhbhai Patel as Minister for Home and States Affairs had the responsibility of welding the British Indian provinces and the princely states into a united India. General El Edroos ( at right ) offers his surrender of the Hyderabad State Forces to Major General ( later General and Army Chief ) Joyanto Nath Chaudhuri at Secunderabad. British India consisted of 17 provinces and 562 princely states. The provinces were given to India or Pakistan, in some cases in particular -- Punjab and Bengal -- after being partitioned. The princes of the princely states, however, were given the right to either remain independent or join either dominion. Thus India 's leaders were faced with the prospect of inheriting a fragmented nation with independent provinces and kingdoms dispersed across the mainland. Under the leadership of Sardar Vallabhbhai Patel, the new Government of India employed political negotiations backed with the option ( and, on several occasions, the use ) of military action to ensure the primacy of the central government and of the Constitution then being drafted. Sardar Patel and V.P. Menon convinced the rulers of princely states contiguous to India to accede to India. Many rights and privileges of the rulers of the princely states, especially their personal estates and privy purses, were guaranteed to convince them to accede. Some of them were made Rajpramukh ( governor ) and Uprajpramukh ( deputy governor ) of the merged states. Many small princely states were merged to form viable administrative states such as Saurashra, PEPSU, Vindhya Pradesh and Madhya Bharat. Some princely states such as Tripura and Manipur acceded later in 1949. There were three states that proved more difficult to integrate than others : Junagadh ( Hindu majority state with a Muslim nawab ) -- a December 1947 plebiscite resulted in a 99 % vote to merge with India, annulling the controversial accession to Pakistan, which was made by the Nawab against the wishes of the people of the state who were overwhelmingly Hindu and despite Junagadh not being contiguous with Pakistan. Hyderabad ( Hindu majority state with a Muslim nizam ) -- Patel ordered the Indian army to depose the government of the Nizam after the failure of negotiations, which was done between 13 -- 17 September 1948. It was incorporated as a state of India the next year. The area of Kashmir ( Muslim majority state with a Hindu king ) in the far north of the subcontinent quickly became a source of controversy that erupted into the First Indo - Pakistani War which lasted from 1947 to 1949. Eventually a United Nations - overseen ceasefire was agreed that left India in control of two - thirds of the contested region. Jawaharlal Nehru initially agreed to Mountbatten 's proposal that a plebiscite be held in the entire state as soon as hostilities ceased, and a UN-sponsored cease - fire was agreed to by both parties on 1 Jan. 1949. No statewide plebiscite was held, however, for in 1954, after Pakistan began to receive arms from the United States, Nehru withdrew his support. The Indian Constitution came into force in Kashmir on 26 January 1950 with special clauses for the state. Constitution Main article : Constitution of India The Constituent Assembly adopted the Constitution of India, drafted by a committee headed by Dr. B.R. Ambedkar, on 26 November 1949. India became a sovereign democratic republic after its constitution came into effect on 26 January 1950. Dr. Rajendra Prasad became the first President of India. The three words ' socialist ', ' secular ' and ' integrity ' were added later with the 42nd Constitution Amendment 1976. Indo - Pakistani War of 1947 -- 1948 Main article : Indo - Pakistani War of 1947 Indian soldiers during the Indo - Pakistani War of 1947. The Indo - Pakistani War of 1947 -- 1948 was fought between India and Pakistan over the princely state of Kashmir and Jammu from 1947 to 1948. It was the first of four Indo - Pakistan Wars fought between the two newly independent nations. Pakistan precipitated the war a few weeks after independence by launching tribal lashkar ( militia ) from Waziristan, in an effort to secure Kashmir, the future of which hung in the balance. The inconclusive result of the war still affects the geopolitics of both countries. 1950s and 1960s Jawaharlal Nehru, the first Prime Minister of India. He oversaw India 's transition from a colony to a republic, while nurturing a plural, multi-party system. In foreign policy, he took a leading role in the Non-Aligned Movement while projecting India as a regional hegemon in South Asia. India held its first national elections under the Constitution in 1952, where a turnout of over 60 % was recorded. The National Congress Party won an overwhelming majority, and Jawaharlal Nehru began a second term as Prime Minister. President Prasad was also elected to a second term by the electoral college of the first Parliament of India. Nehru administration ( 1952 -- 1964 ) Prime Minister Nehru led the Congress to major election victories in 1957 and 1962. The Parliament passed extensive reforms that increased the legal rights of women in Hindu society, and further legislated against caste discrimination and untouchability. Nehru advocated a strong initiative to enroll India 's children to complete primary education, and thousands of schools, colleges and institutions of advanced learning, such as the Indian Institutes of Technology, were founded across the nation. Nehru advocated a socialist model for the economy of India -- no taxation for Indian farmers, minimum wage and benefits for blue - collar workers, and the nationalisation of heavy industries such as steel, aviation, shipping, electricity and mining. Village common lands were seized, and an extensive public works and industrialisation campaign resulted in the construction of major dams, irrigation canals, roads, thermal and hydroelectric power stations and many more. States Reorganisation Main article : States Reorganisation Act Potti Sreeramulu 's fast - unto - death, and consequent death for the demand of an Andhra State in 1953 sparked a major re-shaping of the Indian Union. Nehru appointed the States Re-organisation Commission, upon whose recommendations the States Reorganisation Act was passed in 1956. Old states were dissolved and new states created on the lines of shared linguistic and ethnic demographics. The separation of Kerala and the Telugu - speaking regions of Madras State enabled the creation of an exclusively Tamil - speaking state of Tamil Nadu. On 1 May 1960, the states of Maharashtra and Gujarat were created out of the bilingual Bombay State, and on 1 November 1966, the larger Punjab state was divided into the smaller, Punjabi - speaking Punjab and Haryanvi - speaking Haryana states.

Sino - Indian War resulted in a Chinese victory. Aksai Chin comes under exclusive Chinese control. Nehru 's foreign policy was the inspiration of the Non-Aligned Movement, of which India was a co-founder. Nehru maintained friendly relations with both the United States and the Soviet Union, and encouraged the People 's Republic of China to join the global community of nations. In 1956, when the Suez Canal Company was seized by the Egyptian government, an international conference voted 18 - 4 to take action against Egypt. India was one of the four backers of Egypt, along with Indonesia, Sri Lanka, and the USSR. India had opposed the partition of Palestine and the 1956 invasion of the Sinai by Israel, the United Kingdom and France, but did not oppose the Chinese direct control over Tibet, and the suppression of a pro-democracy movement in Hungary by the Soviet Union. Although Nehru disavowed nuclear ambitions for India, Canada and France aided India in the development of nuclear power stations for electricity. India also negotiated an agreement in 1960 with Pakistan on the just use of the waters of seven rivers shared by the countries. Nehru had visited Pakistan in 1953, but owing to political turmoil in Pakistan, no headway was made on the Kashmir dispute. India has fought a total of four wars / military conflicts with its rival nation Pakistan, two in this period. In the Indo - Pakistani War of 1947, fought over the disputed territory of Kashmir, Pakistan captured one - third of Kashmir ( which India claims as its territory ), and India reclaimed three - fifths ( which Pakistan claims as its territory ). In the Indo - Pakistani War of 1965, India attacked Pakistan on all fronts after attempts by Pakistani troops to infiltrate Indian - controlled Kashmir. In 1961, after continual petitions for a peaceful handover, India invaded and annexed the Portuguese colony of Goa on the west coast of India. In 1962 China and India engaged in the brief Sino - Indian War over the border in the Himalayas. The war was a complete rout for the Indians and led to a refocusing on arms build - up and an improvement in relations with the United States. China withdrew from disputed territory in what is to China South Tibet, and to India part of the North - East Frontier Agency that it crossed during the war. Unrelated to that war, India disputes China 's sovereignty over the smaller Aksai Chin territory that it controls on the western part of the Sino - Indian border. Post-nehru India Nehru 's daughter Indira Gandhi served as prime minister for three consecutive terms ( 1966 -- 77 ) and a fourth term ( 1980 -- 84 ). Jawaharlal Nehru died on 27 May 1964. Lal Bahadur Shastri succeeded him as Prime Minister. In 1965 in the Second Kashmir War India and Pakistan again went to war over Kashmir, but without any definitive outcome or alteration of the Kashmir boundary. The Tashkent Agreement was signed under the mediation of the Soviet government, but Shastri died on the night after the signing ceremony. A leadership election resulted in the elevation of Indira Gandhi, Nehru 's daughter who had been serving as Minister for Information and Broadcasting, as the third Prime Minister. She defeated right - wing leader Morarji Desai. The Congress Party won a reduced majority in the 1967 elections owing to widespread disenchantment over rising prices of commodities, unemployment, economic stagnation and a food crisis. Indira Gandhi had started on a rocky note after agreeing to a devaluation of the rupee, which created much hardship for Indian businesses and consumers, and the import of wheat from the United States fell through due to political disputes. Morarji Desai entered Gandhi 's government as Deputy Prime Minister and Finance Minister, and with senior Congress politicians attempted to constrain Gandhi 's authority. But following the counsel of her political advisor P.N. Haksar, Gandhi resuscitated her popular appeal by a major shift towards socialist policies. She successfully ended the Privy Purse guarantee for former Indian royalty, and waged a major offensive against party hierarchy over the nationalisation of India 's banks. Although resisted by Desai and India 's business community, the policy was popular with the masses. When Congress politicians attempted to oust Gandhi by suspending her Congress membership, Gandhi was empowered with a large exodus of Members of Parliament to her own Congress ( R ). The bastion of the Indian freedom struggle, the Indian National Congress, had split in 1969. Gandhi continued to govern with a slim majority. 1970s Indian T - 55 tanks on their way to Dacca ( present - day Dhaka, Bangladesh ), during the Indo - Pakistani War of 1971 resulting in the Liberation of Bangladesh. In 1971, Indira Gandhi and her Congress ( R ) were returned to power with a massively increased majority. The nationalisation of banks was carried out, and many other socialist economic and industrial policies enacted. India intervened in the Bangladesh War of Independence, a civil war taking place in Pakistan 's Bengali half, after millions of refugees had fled the persecution of the Pakistani army. The clash resulted in the independence of East Pakistan, which became known as Bangladesh, and Prime Minister Indira Gandhi 's elevation to immense popularity. Relations with the United States grew strained, and India signed a 20 - year treaty of friendship with the Soviet Union - breaking explicitly for the first time from non-alignment. In 1974, India tested its first nuclear weapon in the desert of Rajasthan, near Pokhran. Meanwhile, in the Indian protectorate of Sikkim, a referendum was held that resulted in a vote to formally join India and depose the Chogyal. On 26 April 1975, Sikkim formally became India 's 22nd state. Green Revolution and Operation flood Main articles : Green Revolution in India and Operation Flood India 's population passed the 500 million mark in the early 1970s, but its long - standing food crisis was resolved with greatly improved agricultural productivity due to the Green Revolution. The government sponsored modern agricultural implements, new varieties of generic seeds, and increased financial assistance to farmers that increased the yield of food crops such as wheat, rice and corn, as well as commercial crops like cotton, tea, tobacco and coffee. Increased agricultural productivity expanded across the states of the Indo - Gangetic Plain and the Punjab. Under Operation Flood, the government encouraged the production of milk, which increased greatly, and improved rearing of livestock across India. This enabled India to become self - sufficient in feeding its own population, ending two decades of food imports. Indo - Pakistan War of 1971 Main article : Indo - Pakistan War of 1971 The Indo - Pakistani War of 1971 concluded with Lieutenant - General A.A.K. Niazi, the commander of Pakistan Eastern Command, signing the instrument of surrender in Dhaka on 16 Dec 1971, in the presence of India 's Lt. Gen. Jagjit Singh Aurora.

In this war, fought over the issue of self rule in East Pakistan, India decisively defeated Pakistan, resulting in the creation of Bangladesh. Indian emergency Main article : Indian Emergency Economic and social problems, as well as allegations of corruption, caused increasing political unrest across India, culminating in the Bihar Movement. In 1974, the Allahabad High Court found Indira Gandhi guilty of misusing government machinery for election purposes. Opposition parties conducted nationwide strikes and protests demanding her immediate resignation. Various political parties united under Jaya Prakash Narayan to resist what he termed Gandhi 's dictatorship. Leading strikes across India that paralysed its economy and administration, Narayan even called for the Army to oust Gandhi. In 1975, Gandhi advised President Fakhruddin Ali Ahmed to declare a state of emergency under the constitution, which allowed the central government to assume sweeping powers to defend law and order in the nation. Explaining the breakdown of law and order and threat to national security as her primary reasons, Gandhi suspended many civil liberties and postponed elections at national and state levels. Non-Congress governments in Indian states were dismissed, and nearly 1,000 opposition political leaders and activists were imprisoned and a programme of compulsory birth control introduced. Strikes and public protests were outlawed in all forms. India 's economy benefited from an end to paralysing strikes and political disorder. India announced a 20 - point programme which enhanced agricultural and industrial production, increasing national growth, productivity and job growth. But many organs of government and many Congress politicians were accused of corruption and authoritarian conduct. Police officers were accused of arresting and torturing innocent people. Indira 's son and political advisor, Sanjay Gandhi, was accused of committing gross excesses - Sanjay was blamed for the Health Ministry carrying out forced vasectomies of men and sterilisation of women as a part of the initiative to control population growth, and for the demolition of slums in Delhi near the Turkmen Gate, which left thousands of people dead and many more displaced. Janata interlude Main article : Janata Party Morarji Desai, the first non-Congress Prime Minister of India, signing the `` New Delhi '' declaration during a visit by US President Jimmy Carter. Indira Gandhi 's Congress Party called for general elections in 1977, only to suffer a humiliating electoral defeat at the hands of the Janata Party, an amalgamation of opposition parties. Morarji Desai became the first non-Congress Prime Minister of India. The Desai administration established tribunals to investigate Emergency - era abuses, and Indira and Sanjay Gandhi were arrested after a report from the Shah Commission. But in 1979, the coalition crumbled and Charan Singh formed an interim government. The Janata party had become intensely unpopular due to its internecine warfare, and a perceived lack of leadership on solving India 's serious economic and social problems. 1980s Main articles : Operation Blue Star, Indira Gandhi assassination, 1984 anti-Sikh riots, Bhopal disaster, Indian intervention in the Sri Lankan Civil War, and Siachen conflict Indira Gandhi and her Congress Party splinter group, the Indian National Congress or simply `` Congress '', were swept back into power with a large majority in January 1980. But the rise of an insurgency in Punjab would jeopardise India 's security. In Assam, there were many incidents of communal violence between native villagers and refugees from Bangladesh, as well as settlers from other parts of India. When Indian forces, undertaking Operation Blue Star, raided the hideout of self - rule pressing Khalistan militants in the Golden Temple - Sikhs ' most holy shrine - in Amritsar, the inadvertent deaths of civilians and damage to the temple building inflamed tensions in the Sikh community across India. The Government used intensive police operations to crush militant operations, but it resulted in many claims of abuse of civil liberties. Northeast India was paralysed owing to the ULFA 's clash with Government forces. On 31 October 1984, the Prime Minister 's own Sikh bodyguards assassinated her, and 1984 anti-Sikh riots erupted in Delhi and parts of Punjab, causing the deaths of thousands of Sikhs along with terrible pillage, arson and rape. Senior members of the Congress Party have been implicated in stirring the violence against Sikhs. Government investigation has failed to date to discover the causes and punish the perpetrators, but public opinion blamed Congress leaders for directing attacks on Sikhs in Delhi. Rajiv Gandhi administration The Congress party chose Rajiv Gandhi, Indira 's older son, as the next Prime Minister. Rajiv had been elected to Parliament only in 1982, and at 40, was the youngest national political leader and Prime Minister ever. But his youth and inexperience were an asset in the eyes of citizens tired of the inefficacy and corruption of career politicians, and looking for newer policies and a fresh start to resolve the country 's long - standing problems. The Parliament was dissolved, and Rajiv led the Congress party to its largest majority in history ( over 415 seats out of 545 possible ), reaping a sympathy vote over his mother 's assassination. Rajiv Gandhi initiated a series of reforms - the Licence Raj was loosened, and government restrictions on foreign currency, travel, foreign investment and imports decreased considerably. This allowed private businesses to use resources and produce commercial goods without government bureaucracy interfering, and the influx of foreign investment increased India 's national reserves. As Prime Minister, Rajiv broke from his mother 's precedent to improve relations with the United States, which increased economic aid and scientific co-operation. Rajiv 's encouragement of science and technology resulted in a major expansion of the telecommunications industry and India 's space programme, and gave birth to the software industry and information technology sector. Bhopal gas disaster girl, the burial of one iconic victim of the Bhopal disaster ( 4 December 1984 ). In December 1984, gas leaked out at the Union Carbide pesticides plant in the central Indian city of Bhopal. Thousands were killed immediately, while many more subsequently died or were left disabled. India in 1987 brokered an agreement between the Government of Sri Lanka and agreed to deploy troops for peacekeeping operation in Sri Lanka 's ethnic conflict led by the LTTE. Rajiv sent Indian troops to enforce the agreement and disarm the Tamil rebels, but the Indian Peace Keeping Force, as it was known, became entangled in outbreaks of violence - ultimately ending up fighting the Tamil rebels itself, and becoming a target of attack from Sri Lankan nationalists. V.P. Singh withdrew the IPKF in 1990, but thousands of Indian soldiers had died. Rajiv 's departure from Socialist policies did not sit well with the masses, who did not benefit from the innovations. Unemployment was a serious problem, and India 's burgeoning population added ever - increasing needs for diminishing resources. Rajiv Gandhi 's image as an honest politician ( he was nicknamed `` Mr. Clean '' by the press ) was shattered when the Bofors scandal broke, revealing that senior government officials had taken bribes over defence contracts by a Swedish guns producer. Janata Dal General elections in 1989 gave Rajiv 's Congress a plurality, a far cry from the majority which propelled him to power. Power came instead to his former finance and defence minister, VP Singh of Janata Dal. Singh had been moved from the Finance ministry to the Defence ministry after he unearthed some scandals which made the Congress leadership uncomfortable. Singh then unearthed the Bofors scandal, and was sacked from the party and office. Becoming a popular crusader for reform and clean government, Singh led the Janata Dal coalition to a majority. He was supported by BJP and the leftist parties from outside. Becoming Prime Minister, Singh made an important visit to the Golden Temple shrine, to heal the wounds of the past. He started to implement the controversial Mandal Commission report, to increase the quota in reservation for low - caste Hindus. The BJP protested these implementations and took its support back, following which he resigned. Chandra Shekhar split to form the Janata Dal ( Socialist ), supported by Rajiv 's Congress. This new government also collapsed in a matter of months, when Congress withdrew its support. 1990s Main articles : 1990s in India, Rajiv Gandhi assassination, Insurgency in Jammu and Kashmir, and Bombay Riots The stone mosaic that stands at the exact location where Rajiv Gandhi was assassinated in Sriperumbudur. The then - Chief Minister of Jammu and Kashmir Farooq Abdullah ( son of former Chief Minister Sheikh Abdullah ) announced an alliance with the ruling Congress party for the elections of 1987. But, the elections were allegedly rigged in favour of him. This led to the rise of the armed Muslim insurgency in Jammu and Kashmir composed, in part, of those who unfairly lost elections. Pakistan supplied these groups with logistical support, arms, recruits and training. Islamist militants in Kashmir killed and tortured local Kashmiri Pandits, who were Hindu, forcing them to leave Kashmir in large numbers. Around 90 % of the Kashmiri Pandits left Kashmir during the 1990s, resulting in the ethnic cleansing of Kashmiri Hindus. On 21 May 1991, while former Prime Minister Rajiv Gandhi campaigned in Tamil Nadu on behalf of Congress ( Indira ), a Liberation Tigers of Tamil Eelam ( LTTE ) female suicide bomber assassinated him and many others, setting off the bomb in her belt by leaning forward while garlanding him. In the elections, Congress ( Indira ) won 244 parliamentary seats and put together a coalition, returning to power under the leadership of P.V. Narasimha Rao. This Congress - led government, which served a full five - year term, initiated a gradual process of economic liberalisation and reform, which has opened the Indian economy to global trade and investment. India 's domestic politics also took new shape, as traditional alignments by caste, creed, and ethnicity gave way to a plethora of small, regionally - based political parties. But India was rocked by communal violence ( see Bombay Riots ) between Hindus and Muslims that killed over 10,000 people, following the Babri Mosque demolition by Hindu extremists in the course of the Ram Janmabhoomi dispute in Ayodhya in 1992. The final months of the Rao - led government in the spring of 1996 suffered the effects of several major political corruption scandals, which contributed to the worst electoral performance by the Congress Party in its history as the Hindu nationalist Bharatiya Janata Party emerged as the largest single party. Economic reforms Main article : Economic liberalisation in India See also : Indian Century P.V. Narasimha Rao Manmohan Singh Economic liberalisation in India was initiated in 1991 by Prime Minister P.V. Narasimha Rao and his then - Finance Minister Dr. Manmohan Singh. Rao was often referred to as Chanakya for his ability to steer tough economic and political legislation through the parliament at a time when he headed a minority government. Under the policies initiated by late Prime Minister P.V. Narasimha Rao and his then - Finance Minister Dr. Manmohan Singh, India 's economy expanded rapidly. The economic reforms were a reaction to an impending balance of payment crisis. The Rao administration initiated the privatisation of large, inefficient, and loss - inducing government corporations. The UF government had attempted a progressive budget that encouraged reforms, but the 1997 Asian financial crisis and political instability created economic stagnation. The Vajpayee administration continued with privatisation, reduction of taxes, a sound fiscal policy aimed at reducing deficits and debts, and increased initiatives for public works. Cities like Bangalore, Hyderabad, Pune, and Ahmedabad have risen in prominence and economic importance, becoming centres of rising industries and destinations for foreign investment and firms. Strategies like forming Special Economic Zones - tax amenities, good communications infrastructure, low regulation - to encourage industries has paid off in many parts of the country. A rising generation of well - educated and skilled professionals in scientific sectors of industry began propelling the Indian economy, as the information technology industry took hold across India with the proliferation of computers. The new technologies increased the efficiency of activity in almost every type of industry, which also benefitted from the availability of skilled labor. Foreign investment and outsourcing of jobs to India 's labor markets further enhanced India 's economic growth. A large middle class has arisen across India, which has increased the demand, and thus production of a wide array of consumer goods. Unemployment is steadily declining, and poverty has fallen to approximately 22 %. Gross Domestic Product growth increased to beyond 7 %. While serious challenges remain, India is enjoying a period of economic expansion that has propelled it to the forefront of the world economy, and has correspondingly increased its influence in political and diplomatic terms. Era of coalitions The Bharatiya Janata Party ( BJP ) emerged from the May 1996 national elections as the single - largest party in the Lok Sabha but without enough strength to prove a majority on the floor of that Parliament. Under Prime Minister Atal Bihari Vajpayee, the BJP coalition lasted in power 13 days. With all political parties wishing to avoid another round of elections, a 14 - party coalition led by the Janata Dal emerged to form a government known as the United Front. A United Front government under former Chief Minister of Karnataka H.D. Deve Gowda lasted less than a year. The leader of the Congress Party withdrew support in March 1997. Inder Kumar Gujral replaced Deve Gowda as the consensus choice for Prime Minister of a 16 - party United Front coalition. Shakti I, prior to its detonation. Pokhran - II or `` Operation Shakti '', was the series of five nuclear bomb test explosions at the Indian Army 's Pokhran Test Range in May 1998 ; resulted in the Indian government, led by Prime Minister Atal Bihari Vajpayee, convening a press conference to declare India a full - fledged nuclear state. In November 1997, the Congress Party again withdrew support for the United Front. New elections in February 1998 brought the BJP the largest number of seats in Parliament ( 182 ), but this fell far short of a majority. On 20 March 1998, the President inaugurated a BJP - led coalition government, with Vajpayee again serving as Prime Minister. On 11 and 13 May 1998, this government conducted a series of five underground nuclear weapons tests, known collectively as Pokhran - II -- which caused Pakistan to conduct its own tests that same year. India 's nuclear tests prompted President of the United States Bill Clinton and Japan to impose economic sanctions on India pursuant to the 1994 Nuclear Proliferation Prevention Act and led to widespread international condemnation. In the early months of 1999, Prime Minister Vajpayee made a historic bus trip to Pakistan and met with Pakistan 's Prime Minister Nawaz Sharif, signing the bilateral Lahore peace declaration. In April 1999, the coalition government led by the Bharatiya Janata Party ( BJP ) fell apart, leading to fresh elections in September. In May and June 1999, India discovered an elaborate campaign of terrorist infiltration that resulted in the Kargil War in Kashmir, derailing a promising peace process that had begun only three months earlier when Prime Minister Vajpayee visited Pakistan, inaugurating the Delhi - Lahore bus service. Indian forces killed Pakistan - backed infiltrators and reclaimed important border posts in high - altitude warfare. Soaring on popularity earned following the successful conclusion of the Kargil conflict, the National Democratic Alliance - a new coalition led by the BJP - gained a majority to form a government with Vajpayee as Prime Minister in October 1999. The end of the millennium was devastating to India, as a cyclone hit Orissa, killing at least 10,000. 2000s Under Bharatiya Janata Party Atal Bihari Vajpayee became the first non-Congress Prime Minister to complete a full term. His tenure saw rapid growth of infrastructure, improved diplomatic relationship with the United States, economic reforms, nuclear tests, several foreign policy and military victories. In 2000 May, India 's population exceeded 1 billion. President of the United States Bill Clinton made a groundbreaking visit to India to improve ties between the two nations. In January, massive earthquakes hit Gujarat state, killing at least 30,000. Prime Minister Vajpayee met with Pakistan 's President Pervez Musharraf in the first summit between Pakistan and India in more than two years in the middle of 2001. But the meeting failed without a breakthrough or even a joint statement because of differences over Kashmir region. Three new states -- Chhattisgarh, Jharkhand and Uttarakhand ( originally Uttaranchal ) -- were formed in November 2000. The National Democratic Alliance government 's credibility was adversely affected by a number of political scandals ( such as allegations that the Defence Minister George Fernandes took bribes ) as well as reports of intelligence failures that led to the Kargil incursions going undetected, and the apparent failure of his talks with the Pakistani President. Following the 11 September attacks, the United States lifted sanctions which it had imposed against India and Pakistan in 1998. The move was seen as a reward for their support for the War on Terror. The tensions of an imminent war between India and Pakistan again rose by the heavy Indian firing on Pakistani military posts along the Line of Control and the subsequent deadly Indian Parliament attack and the 2001 -- 02 India -- Pakistan standoff. In 2002, 59 Hindu pilgrims returning from Ayodhya were killed in a train fire in Godhra, Gujarat. This sparked off the 2002 Gujarat violence, leading to the deaths of 790 Muslims and 254 Hindus and with 223 people reported missing. Throughout 2003, India 's speedy economic progress, political stability and a rejuvenated peace initiative with Pakistan increased the government 's popularity. India and Pakistan agreed to resume direct air links and to allow overflights, and a groundbreaking meeting was held between the Indian government and moderate Kashmir separatists. The Golden Quadrilateral project aimed to link India 's corners with a network of modern highways. Congress rule returns In January 2004 Prime Minister Vajpayee recommended early dissolution of the Lok Sabha and general elections. The Congress Party - led alliance won a surprise victory in elections held in May 2004. Manmohan Singh became the Prime Minister, after the Congress President Sonia Gandhi ( born Antonia Edvige Albina Maino ), the widow of former Prime Minister Rajiv Gandhi, declined to take the office, in order to defuse the controversy about whether her foreign birth should be considered a disqualification for the Prime Minister 's post. The Congress formed a coalition called the United Progressive Alliance with Socialist and regional parties, and enjoyed the outside support of India 's Communist parties. Manmohan Singh became the first Sikh and non-Hindu to hold India 's most powerful office. Singh continued economic liberalisation, although the need for support from Indian Socialists and Communists forestalled further privatisation for some time. U.S. President George W. Bush and India 's Prime Minister Manmohan Singh exchange handshakes in New Delhi on 2 March 2006. By the end of 2004, India began to withdraw some of its troops from Kashmir. By the middle of the next year, the Srinagar -- Muzaffarabad Bus service was inaugurated, the first in 60 years to operate between Indian - administered and Pakistani - administered Kashmirs. However, in May 2006, suspected Islamic extremist militants killed 35 Hindus in the worst attacks in Indian - administered Kashmir for several months. The 2004 Indian Ocean earthquake and tsunami devastated Indian coastlines and islands, killing an estimated 18,000 and displacing around 650,000. The tsunami was caused by a powerful undersea earthquake off the Indonesian coast. Natural disasters such as the Mumbai floods ( killing more than 1,000 ) and Kashmir earthquake ( killing 79,000 ) hit the subcontinent in the next year. In February 2006, the United Progressive Alliance government launched India 's largest - ever rural jobs scheme, aimed at lifting around 60 million families out of poverty. The United States and India signed a major nuclear co-operation agreement during a visit by United States President George W. Bush in March 2006. According to the nuclear deal, the United States was to give India access to civilian nuclear technology while India agreed to greater scrutiny for its nuclear programme. Later United States approved a controversial law allowing India to buy their nuclear reactors and fuel for the first time in 30 years. In July 2008, the United Progressive Alliance survived a vote of confidence brought after left - wing parties withdrew their support over the nuclear deal. After the vote, several left - wing and regional parties formed a new alliance to oppose the government, saying it had been tainted by corruption. Within three months, following approval by the U.S. Congress, George W. Bush signed into law a nuclear deal with India, which ended a three - decade ban on American nuclear trade with Delhi. In 2007 India got its first female President as Pratibha Patil was sworn in. Long associated with the Nehru -- Gandhi family, Pratibha Patil was a low - profile governor of the state of Rajasthan before emerging as the favoured presidential candidate of Sonia Gandhi. In February, the infamous Samjhauta Express bombings took place, killing Pakistani civilians in Panipat, Haryana. As of 2011, nobody had been charged for the crime, though it has been linked to Abhinav Bharat, a shadowy Hindu fundamentalist group headed by a former Indian army officer. In 2008 October, India successfully launched its first mission to the Moon, the unmanned lunar probe called Chandrayaan - 1. In the previous year, India had launched its first commercial space rocket, carrying an Italian satellite. In July 2009, the Delhi High Court decriminalised consensual homosexual sex, declaring the British Raj - era law, Section 377 of the Indian Penal Code, as unconstitutional. In November 2008, Mumbai attacks took place. India blamed militants from Pakistan for the attacks and announced a `` pause '' in the ongoing peace process. In the Indian general election in 2009, the United Progressive Alliance won a convincing and resounding 262 seats, with Congress alone winning 206 seats. However, the Congress - led government faced many allegations of corruption. Inflation rose to an all - time high, and the ever - increasing prices of food commodities caused widespread agitation. 21st - century India is facing the Naxalite - Maoist rebels, in the words of Prime Minister Manmohan Singh, India 's `` greatest internal security challenge '', and other terrorist tensions ( such as Islamist terrorist campaigns in and out of Jammu & Kashmir and terrorism in India 's Northeast ). Terrorism has increased in India, with bomb blasts in leading cities like Mumbai, New Delhi, Jaipur, Bangalore, and Hyderabad. In the new millennium, India improved relations with many countries and foreign unions including the United States, the European Union, Israel, and the People 's Republic of China. The economy of India has grown at a very rapid pace. India is now being looked at as a potential superpower. 2010s India Against Corruption campaign in Delhi ; supporters of Anna Hazare on the road near Ramlila Maidan. The concerns and controversies over the 2010 Commonwealth Games rocked the country in 2010, raising questions about the credibility of the government followed by the 2G spectrum scam and Adarsh Housing Society scam. In mid-2011, Anna Hazare, a prominent social activist, staged a 12 - day hunger strike in Delhi in protest at state corruption, after government proposals to tighten up anti-graft legislation fell short of his demands. Despite all this, India showed great promise with a higher growth rate in gross domestic product. In January 2011, India assumed a nonpermanent seat in the United Nations Security Council for the 2011 - 12 term. In 2004, India had launched an application for a permanent seat on the UN Security Council, along with Brazil, Germany and Japan. In March, India overtook China to become the world 's largest importer of arms. The Telangana movement reached its peak in 2011 - 12, leading to formation of India 's 29th state, Telangana, in June 2014. The 2012 Delhi gang rape case and subsequent protest by civil society resulted in changes in the laws related to rape and offences against women. In April 2013, the Saradha Group financial scandal was unearthed, caused by the collapse of a Ponzi scheme run by Saradha Group, a consortium of over 200 private companies in Eastern India, causing an estimated loss of INR 200 -- 300 billion ( US $4 -- 6 billion ) to over 1.7 million depositors. In December 2013, the Supreme Court of India overturned the Delhi High Court ruling on Sec 377, criminalising homosexual sex between consenting adults once again in the country. In August 2010, cloudbursts and the ensuing flooding in the Ladakh region of North India resulted in the deaths of around 255 people, while affecting 9,000 people directly. In June 2013, a multi-day cloudburst in Uttarakhand and other north Indian states caused devastating floods and landslides, with more than 5,700 people `` presumed dead. '' In September 2014, floods in the state of Jammu and Kashmir, following heavy rains due to monsoon season, killed around 277 people and brought extensive damage to property. A further 280 people died in the neighbouring Pakistani regions, particularly in Pakistani Punjab. In August - September 2013, clashes between Hindus and Muslims in Muzaffarnagar, Uttar Pradesh, resulted in at least 62 deaths, injured 93, and left more than 50,000 displaced. In November 2013, India launched its first interplanetary mission, the Mars Orbiter Mission, popularly known as Mangalyaan, to Mars and, was successful, so ISRO on 24 September 2014, became the fourth space agency to reach Mars, after the Soviet space program, NASA, and the European Space Agency. ISRO also became the first space agency and India the first country to reach Mars on its maiden attempt. 2014 -- return of Bharatiya Janata Party ( BJP ) government Prime Minister Modi at the launch of the Make in India programme. The Hindutva movement advocating Hindu nationalism originated in the 1920s and has remained a strong political force in India. The major party of the religious right, Bharatiya Janata Party ( BJP ), since its foundation in 1980 won elections, and after a defeat in 2004 remained one of the leading forces against the coalition government of the Congress Party. The 16th national general election, held in early 2014, saw a dramatic victory of the BJP ; it gained an absolute majority and formed a government under the premiership of Narendra Modi, a BJP leader and till then the Chief Minister of Gujarat. The Modi government 's sweeping mandate and popularity helped the BJP win several State Assembly elections in India. The Modi government implemented several initiatives and campaigns to increase manufacturing and infrastructure -- notably -- Make in India, Digital India and Swachh Bharat Abhiyan.
