Foreign relations of India
India's relations with the world have evolved since the British Raj (1857–1947), when the British Empire monopolised external and defence relations. When India gained independence in 1947, few Indians had experience in making or conducting foreign policy. However, the country's oldest political party, the Indian National Congress, had established a small foreign department in 1925 to make overseas contacts and to publicise its independence struggle. From the late 1920s on, Jawaharlal Nehru, who had a long-standing interest in world affairs among independence leaders, formulated the Congress stance on international issues. As a member of the interim government in 1946, Nehru articulated India's approach to the world.
India
Since its independence in 1947, India has maintained cordial relations with most nations. In the 1950s, it strongly supported decolonisation in Africa and Asia and played a lead role in the Non-Aligned Movement. In the late 1980s, the Indian military twice intervened abroad at the invitation of neighbouring countries: a peace-keeping operation in Sri Lanka between 1987 and 1990; and an armed intervention to prevent a 1988 coup d'état attempt in the Maldives. India has tense relations with neighbouring Pakistan; the two nations have gone to war four times: in 1947, 1965, 1971, and 1999. Three of these wars were fought over the disputed territory of Kashmir, while the fourth, the 1971 war, followed from India's support for the independence of Bangladesh. After waging the 1962 Sino-Indian War and the 1965 war with Pakistan, India pursued close military and economic ties with the Soviet Union; by the late 1960s, the Soviet Union was its largest arms supplier.
