The event that led to the eventual independence of India in 1947 was the culmination of a prolonged struggle against British colonial rule, marked by the Indian Independence Movement. Significant milestones in this movement include the formation of the Indian National Congress in 1885 and the widespread civil disobedience and non-violent protests led by figures such as Mahatma Gandhi. Post-World War II, Britain faced immense pressure from both Indian nationalists and international forces, leading to negotiations for independence. The Mountbatten Plan eventually resulted in the partitioning of India into two sovereign states, India and Pakistan, officially granting independence on August 15, 1947.
