U.S. Recognition of Indian Independence, 1947
The United States recognized the Union of India as an independent state on August 15, 1947, when President Harry S. Truman sent a congratulatory message to Lord Louis Mountbatten, Governor General of the Dominion of India. It was on this date that, in accordance with the British Parliament’s India Independence Act of July 18, 1947, the Union of India and Pakistan were created from the former “British India” that had been a part of the British Empire.
The formal process that led to Indian independence began with a report that the British government issued on May 16, 1946, which recommended the formation of an interim government in India to devise a constitution as part of a process by which India would achieve independence from Great Britain. An Interim Government of India was formed on September 2, 1946, and this is the government with which the United States established diplomatic relations prior to formal Indian independence.
