The war effort required a massive increase in industrial production, and the government took steps to coordinate and control the economy. This led to the creation of new government agencies, such as the War Industries Board, which supervised the allocation of resources and the production of war materials. The war also spurred the growth of American industry, particularly in the areas of steel, shipbuilding, and munitions.
In addition to mobilizing the economy, the war also led to a significant increase in the size of the American military. Millions of men were drafted into service, and the government also created new volunteer organizations, such as the American Expeditionary Force (AEF), which fought in Europe. The war also had a major impact on American society, as women entered the workforce in large numbers to replace men who were fighting overseas. This led to a shift in traditional gender roles and helped to pave the way for greater equality for women in the years to come.
The war also had a significant impact on American politics and foreign policy. The United States emerged from the war as a major world power, and the war helped to shape the country's role in international affairs in the years that followed. The war also led to a rise in isolationism, as many Americans came to believe that the United States should stay out of European conflicts. However, the war also had a lasting impact on American patriotism and national identity, and it helped to unify the country in the face of a common enemy.
