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–United Kingdom relations
Trade was established between Tudor England and Mughal India in 1600 when Elizabeth I granted the newly formed East India Company a royal charter. After the Mughal Empire's decline in 1707, India was a leading manufacturing country in the world in the early 18th century. It had 22.6 percent share of the world's GDP, by the time British left the country its GDP was near 4%. During 18th century, the East India Company began to gain greater influence in India. The Battle of Plassey in 1757 led to the conquest of Bengal while by 1857, following various treaties and wars with Indian kingdoms (such as the Anglo-Mysore Wars with Tipu Sultan, the Anglo-Maratha Wars and the Anglo-Sikh wars), the East India Company controlled most of the Indian subcontinent. Following the Indian Mutiny of 1857, where Indian sepoys rebelled against their British officers, the East India Company was dissolved the following year. The assets of the British East India Company became so huge that the British government decided to step in. India served as the main base for the British Empire's expansion across Asia and would remain the empire's most important colony until independence. Queen Victoria became Empress of India in 1876. From a small trading outpost, India became the jewel in the British crown.
