NCERT Class 12 Indian Polity Chapter 4 – India’s External Relations

NCERT Class 12 Indian Polity Chapter 4 explains the development of India’s foreign policy after Independence in 1947 and the major international challenges faced by the country. Students should refer to the official NCERT website for authentic textbooks and syllabus updates. In NCERT Class 12 Indian Polity Chapter 4, students learn how India managed its relations with major global powers and neighbouring countries during the Cold War period.

NCERT Class 12 Indian Polity Chapter 4 begins with the international context after the Second World War (1939–1945), when the world was divided into two major power blocs led by the United States and the Soviet Union. In this situation, Prime Minister Jawaharlal Nehru (1889–1964) adopted the policy of Non-Alignment, which meant that India would not join any military alliance during the Cold War (1945–1991). The Non-Aligned Movement later became an important platform for newly independent countries of Asia, Africa and Latin America.

Another important topic in NCERT Class 12 Indian Polity Chapter 4 is India’s relationship with neighbouring countries, especially China and Pakistan. Initially, India and China promoted the principle of Panchsheel (Five Principles of Peaceful Coexistence) in 1954, but relations deteriorated due to border disputes, leading to the India–China War of 1962. Similarly, India fought wars with Pakistan in 1947–48, 1965 and 1971, which significantly influenced India’s foreign policy.

NCERT Class 12 Indian Polity Chapter 4 also discusses the Bangladesh War of 1971, which resulted in the creation of the independent nation of Bangladesh on 16 December 1971. The chapter further explains India’s nuclear policy and its emphasis on peaceful use of nuclear technology, including the first nuclear test conducted at Pokhran in Rajasthan on 18 May 1974 during the government of Prime Minister Indira Gandhi.

1. International context

• After the end of Second World War (1939–1945), the global political order changed dramatically, leading to the emergence of two powerful superpowers: the United States of America (USA) and the Soviet Union (USSR).
• The rivalry between these two superpowers led to the beginning of the Cold War (late 1940s–1991), a period marked by political tension, ideological conflict and military competition without direct large-scale war between the two sides.
• The world became divided into two major military and ideological blocs: the Western bloc led by the USA, supporting capitalism and liberal democracy, and the Eastern bloc led by the USSR, supporting socialism and communist political systems.
• Several military alliances were formed during this period, such as the North Atlantic Treaty Organization (NATO) in 1949 led by the United States, and the Warsaw Pact in 1955 led by the Soviet Union.
• Many newly independent countries in Asia and Africa during the late 1940s and 1950s, including India (independent on 15 August 1947), had to decide whether to join one of these power blocs or maintain an independent foreign policy.
• Indian leaders believed that joining either bloc could limit India’s freedom in international decision-making and might involve the country in superpower conflicts.
• Therefore, India sought to develop an independent foreign policy that protected national interests while promoting international peace and cooperation.

2. The policy of non-alignment

• In the context of the Cold War rivalry between the United States (USA) and the Soviet Union (USSR) after World War II (1939–1945), India adopted the foreign policy of Non-Alignment, meaning that it would not join any military alliance led by either superpower.
• The policy was based on the belief that newly independent countries should maintain independence in international decision-making and avoid becoming part of the power politics of the Cold War blocs.
• Non-Alignment did not mean neutrality or indifference in world affairs. Instead, India reserved the right to take independent positions on international issues based on merit and national interest.
• The policy also aimed to promote international peace, cooperation and peaceful coexistence among nations, especially at a time when the world was divided into hostile military alliances.
• India believed that joining a military bloc could drag the country into conflicts between superpowers, which would divert attention from the main national task of economic development after Independence in 1947.
• The idea of Non-Alignment gradually evolved into the Non-Aligned Movement (NAM), which brought together many countries of Asia, Africa and Latin America that wished to remain independent of Cold War power blocs.

2.1 Nehru’s role

• Jawaharlal Nehru (1889–1964), the first Prime Minister of India (1947–1964), played a decisive role in shaping India’s foreign policy during the early years after Independence.
• Nehru strongly believed that India should follow an independent foreign policy based on peace, cooperation and non-alignment, rather than joining either the USA-led Western bloc or the USSR-led socialist bloc.
• He was one of the key leaders who promoted the idea that newly independent countries of Asia and Africa should work together to protect their sovereignty and resist domination by powerful nations.
• Under Nehru’s leadership, India actively participated in international efforts to promote peaceful coexistence, disarmament and reduction of global tensions during the Cold War period.
• Nehru also supported the principle of Panchsheel (Five Principles of Peaceful Coexistence), which were agreed upon between India and China in 1954.
• These principles included mutual respect for territorial integrity, mutual non-aggression, non-interference in internal affairs, equality and mutual benefit, and peaceful coexistence.

2.2 Distance from two camps

• During the Cold War period (late 1940s–1991), the world was divided into two rival military blocs: the Western bloc led by the United States (USA) and the Eastern bloc led by the Soviet Union (USSR).
• India decided to maintain distance from both blocs and follow an independent foreign policy, refusing to join military alliances such as NATO (North Atlantic Treaty Organization, 1949) or the Warsaw Pact (1955).
• This policy allowed India to maintain diplomatic relations with both the USA and the USSR, cooperating with each country whenever it served India’s national interests.
• India believed that maintaining distance from military alliances would help it avoid involvement in Cold War conflicts and focus on its primary task of economic development after Independence in 1947.
• The policy also gave India the freedom to criticise both superpowers when necessary, such as opposing colonialism, racial discrimination and military aggression anywhere in the world.
• Through this approach, India tried to play the role of a mediator and advocate of peace in international affairs, especially among newly independent countries in Asia and Africa.

2.3 Afro-Asian unity

• After Independence in 1947, India strongly supported cooperation among newly independent countries of Asia and Africa, which had recently emerged from colonial rule by European powers.
• Leaders of these countries believed that they faced similar challenges such as poverty, underdevelopment, racial discrimination and political instability, and therefore needed to work together in international affairs.
• A major step toward Afro-Asian cooperation was the Bandung Conference held in Bandung, Indonesia, in April 1955, which brought together leaders from 29 Asian and African countries.
• Important leaders participating in the conference included Jawaharlal Nehru of India, Sukarno of Indonesia, Gamal Abdel Nasser of Egypt, Zhou Enlai of China and Kwame Nkrumah of Ghana.
• The conference promoted the principles of peaceful coexistence, opposition to colonialism and racial discrimination, and cooperation among developing nations.
• The spirit of Afro-Asian solidarity developed at Bandung later contributed to the formation of the Non-Aligned Movement (NAM) in 1961, which became an important platform for developing countries in global politics.

3. Peace and conflict with China

• After India’s Independence in 1947 and the establishment of the People’s Republic of China in 1949 under Mao Zedong, both countries initially tried to build friendly diplomatic relations.
• In 1954, India and China signed an important agreement based on the principles of Panchsheel (Five Principles of Peaceful Coexistence), which included mutual respect for territorial integrity, non-aggression, non-interference in internal affairs, equality and peaceful coexistence.
• During the early 1950s, the relationship between the two countries was often symbolised by the slogan “Hindi-Chini Bhai-Bhai”, reflecting the idea of Asian solidarity and cooperation.
• However, tensions gradually developed due to disputes over the boundary between India and China, particularly in the regions of Aksai Chin in Ladakh and the North-East Frontier Agency (NEFA), which is now Arunachal Pradesh.
• The situation became more complicated after China’s occupation of Tibet in 1950, which removed the traditional buffer between India and China.
• Relations deteriorated further when Tibetan spiritual leader Dalai Lama fled to India in 1959 and was granted political asylum by the Government of India.

3.1 The Chinese invasion, 1962

• Tensions between India and China finally escalated into a full-scale war in October 1962, known as the Sino-Indian War of 1962.
• Chinese forces launched military attacks along the disputed border regions of Ladakh (western sector) and the North-East Frontier Agency – NEFA (eastern sector, now Arunachal Pradesh).
• The Indian Army faced serious difficulties due to lack of adequate military preparation, difficult terrain and logistical challenges, which resulted in significant losses during the conflict.
• The war lasted for about one month from October to November 1962, during which Chinese troops advanced deep into Indian territory in NEFA.
• On 21 November 1962, China declared a unilateral ceasefire and announced that its forces would withdraw from some of the captured territories.
• The conflict severely damaged the earlier spirit of India-China friendship and had a major impact on India’s foreign policy and defence strategy.

4. Wars and peace with Pakistan

• Soon after Independence and Partition in August 1947, India and Pakistan came into conflict over the princely state of Jammu and Kashmir, leading to the first India–Pakistan war of 1947–1948.
• The conflict began when tribal fighters from Pakistan entered Kashmir in October 1947, after which the Maharaja of Jammu and Kashmir, Hari Singh, signed the Instrument of Accession to India on 26 October 1947, and Indian troops were sent to defend the region.
• The war ended in 1948 after intervention by the United Nations (UN), which resulted in a ceasefire and the division of Kashmir along the Line of Control (LoC).
• Another major conflict occurred during the India–Pakistan War of 1965, when Pakistan launched military operations in Kashmir, leading to full-scale fighting between the two countries.
• The war ended after diplomatic efforts by the Soviet Union, resulting in the Tashkent Agreement signed on 10 January 1966 in Tashkent (Uzbekistan) by Indian Prime Minister Lal Bahadur Shastri and Pakistani President Ayub Khan.
• These repeated conflicts kept India–Pakistan relations tense, although both countries periodically attempted to restore peace through diplomatic negotiations.

5. Bangladesh war, 1971

• In 1971, a major political crisis developed in East Pakistan, where the people demanded political autonomy and democratic rights after the victory of the Awami League led by Sheikh Mujibur Rahman in the general elections of 1970.
• The military government of Pakistan under General Yahya Khan refused to transfer power, leading to violent repression by the Pakistani army in East Pakistan in March 1971.
• The violence created a massive refugee crisis, with nearly 10 million refugees from East Pakistan entering India, especially in the states of West Bengal, Assam and Tripura.
• India, under Prime Minister Indira Gandhi (1966–1977), provided political and humanitarian support to the Bengali nationalist movement.
• On 3 December 1971, Pakistan launched military attacks on Indian airfields, which led to the India–Pakistan War of 1971.
• The war ended on 16 December 1971, when Pakistani forces in East Pakistan surrendered to the Indian Army, leading to the creation of the independent country of Bangladesh.

6. India’s nuclear policy

• From the early years after Independence in 1947, India believed that nuclear energy should be used mainly for peaceful purposes such as scientific research, energy production and technological development.
• India opposed the nuclear arms race during the Cold War (late 1940s–1991) and strongly supported the idea of global nuclear disarmament.
• The Indian nuclear programme was led by Dr. Homi Jehangir Bhabha (1909–1966), a leading nuclear scientist who established important institutions such as the Tata Institute of Fundamental Research (TIFR) in 1945 and the Atomic Energy Commission of India in 1948.
• India criticised international agreements like the Nuclear Non-Proliferation Treaty (NPT) of 1968, arguing that the treaty was discriminatory because it allowed existing nuclear powers to keep their weapons while restricting other countries from developing them.
• India conducted its first nuclear test on 18 May 1974 at Pokhran in Rajasthan, during the government of Prime Minister Indira Gandhi, describing it as a “peaceful nuclear explosion.”
• The nuclear test demonstrated India’s scientific and technological capability in nuclear research, while the government continued to maintain that India’s nuclear policy was defensive and focused on national security.
