The main reason that American farmers faced financial challenges after the Civil War was because farmers faced increasing costs and decreased income.

The American Civil War had some considerable consequences besides thousands of lives lost. It impacted in many economic and political issues. Yes, it represented the end of a slavery period and started the reconstruction of the country. But one of the activities that resented the consequences of the Civil War was agriculture. After the war,  American farmers faced financial challenges because farmers faced increasing costs and decreased income. The war affected plantations, reduced the number of slaves that worked in the fields because many of them migrated to the Northern states, and it represented an increase in the cost of production. And as people had less money after the war, they bought less, decreasing the income of farmers.
