The War Industries Board oversaw the creation of goods that are needed for war (guns, ammunition, tanks, etc.). Along with this, the War Industries Board also had the power to give out raw materials and were able to tell companies what products must be made and how many to make. This control over the economy helped the government know that they would have enough materials needed for the war effort.
The consequences of this violent catastrophe were many. A cessation of wars and a sudden slump in trade immediately followed but were only of short duration. A more lasting and serious consequence was the drastic reduction of the amount of land under cultivation, due to the deaths of so many labourers. This proved to be the ruin of many landowners. The shortage of labour compelled them to substitute wages or money rents in place of labour services in an effort to keep their tenants. There was also a general rise in wages for artisans and peasants. These changes brought a new fluidity to the hitherto rigid stratification of society.
