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.

The partition of India was set forth in the Indian Independence Act 1947 and resulted in the dissolution of the British Indian Empire and the end of the British Raj. It resulted in a struggle between the newly constituted states of India and Pakistan and displaced up to 12.5 million people with estimates of loss of life varying from several hundred thousand to a million (most estimates of the numbers of people who crossed the boundaries between India and Pakistan in 1947 range between 10 and 12 million). The violent nature of the partition created an atmosphere of mutual hostility and suspicion between India and Pakistan that plagues their relationship to this day.
The partition included the geographical division of the Bengal province into East Bengal, which became part of the Dominion of Pakistan (from 1956, East Pakistan). West Bengal became part of India, and a similar partition of the Punjab province became West Punjab (later the Pakistani Punjab and Islamabad Capital Territory) and East Punjab (later the Indian Punjab, as well as Haryana and Himachal Pradesh). The partition agreement also included the division of Indian government assets, including the Indian Civil Service, the Indian Army, the Royal Indian Navy, the Indian railways and the central treasury, and other administrative services.
