Why did industrial production in India increase during the First World War? Solution: Industrial production in India increased during the First World War due to the following reasons:

The British mills were busy with war production to meet the needs of the army; thus, Manchester’s imports to India declined.

1. With the decline in imports suddenly, Indian mills had a vast home market to supply.
2. As the war prolonged, Indian factories were called upon to supply war needs also, such as Jute bags, cloth for the uniform of soldiers, tents, and leather boots.
3. New factories were set up, and old ones organised multiple shifts; during the war years, Indian industries boomed.
4. Overall, the First World War gave a boost to Indian industries.
