Question

why did industrial production in India increased during the first world war

Answer 1

Till the First World War, industrial growth was slow.
The war created a dramatically new situation with British mills busy with war production to meet the needs of the army. Manchester imports into India declined. Suddenly, Indian mills had a vast home market to supply.
As the war prolonged, Indian factories were called upon to supply war needs, jute bags, cloth for army uniforms, tents and leather boots, horse and mule siddles and a host of their items.

○India witnessed increased industrial production during the First World War due to following reasons:

British industries became busy in producing and supplying war-needs. Hence, they stopped exporting British goods or clothes for colonial markets, for instance in India.

It was a good opportunity for Indian industries to fill in empty Indian markets with their products. Therefore, industrial production in India increased.

Also the British colonial government asked Indian factories to supply the war needs like - jute bags, cloth or army uniforms, tents and leather boots, horse and mule saddle, etc.

The increased demands of variety of products led to the setting up of new factories and old ones increased their production.

Many new workers were employed and everyone was made to work longer hours
