What happened to american industry in the years after the civil war?

American industry grew tremendously after the Civil War. In the Northeast, Midwest, and plains, there were several hubs for agricultural and industrial growth. Between the mid-1860's and the late 1870's, steel production increased by 1,000 percent, railroad coverage doubled, and the amount of materials transported by freight tripled. The population more than doubled.

After a dramatic economic boom during the First World War, a sharp, short depression hit Alberta in 1920-22. Hardship during the early 1920s was as severe, or even somewhat worse, than those experienced during the much longer Great Depression of the 1930s.

 the First World War in 1914 initiated an enormous demand for agricultural products and helped to mask the serious weaknesses of the provincial economy. With the conclusion of the war, however, unemployment skyrocketed as veterans returned and inflation increased. Grain prices began to fall in 1920, causing further hardships. By the spring of 1921, many Red Deer businesses had gone bankrupt, and the city's unemployment rate was estimated at 20%.
