India, officially the Indian Empire, declared war on Germany in September 1939. The Provinces of India (which included most of modern-day India and the present day Bangladesh, Pakistan and Myanmar), being imperial colonies of the United Kingdom, were by default a part of the Allies of World War II. Several Indian princely states provided large donations to the Allies to combat the threat of Nazism and Fascism (Wikipedia)
