During the 1st world War india wanted to be self sufficient so they set up own factories and institutions and expanded their oroduction

Introduction:
During the First World War (1914-1918), industrial production in India witnessed a significant increase. This can be attributed to several factors that affected different sectors of the Indian economy.

War-related demands:
1. Manufacturing of war materials: The war created a surge in the demand for war-related materials such as ammunition, arms, uniforms, and other supplies. Indian industries were mobilized to meet these demands.
2. Expansion of railways: The war necessitated the expansion and improvement of the railway network in India to transport troops, supplies, and equipment. This led to an increased demand for locomotives, wagons, and railway infrastructure.

Government initiatives:
1. War Procurement Board: The British government established the War Procurement Board in India to regulate and coordinate the procurement of war materials. This board facilitated the allocation of orders to Indian industries, leading to increased production.
2. Establishment of factories: The government set up several new factories to manufacture war-related goods. These included ammunition factories, clothing factories, and engineering works, which contributed to the overall increase in industrial production.
3. Import substitution: Due to disruptions in international trade during the war, there was a need for India to become self-sufficient in certain goods. This led to the establishment of industries that produced goods that were previously imported, further boosting industrial production.

Impact on agriculture:
1. Shift of labor: Many agricultural workers moved to industries in search of better wages and job opportunities. This shift in labor from agriculture to industry resulted in increased industrial production.
2. Increased demand for agricultural products: The war created a higher demand for food supplies, as the armed forces and war-related industries required a steady flow of agricultural products. This led to increased agricultural production to meet the demand.

Conclusion:
The First World War had a significant impact on industrial production in India. The war-related demands, government initiatives, and the shift of labor from agriculture to industry all contributed to the increase in production. This period marked a turning point in the industrialization of India, setting the foundation for further growth and development in the years to come.
