Final answer:
The South's economy was ruined because of the Civil War due to disruptions in cotton exports, difficulties in importing goods, and the destruction of infrastructure.
Step-by-step explanation:
The Civil War had a significant impact on the South's economy. The region's plantation-based economy, which relied heavily on the export of cotton, was greatly disrupted. The naval blockade during the war cut off the flow of cotton to England, the South's primary importer, and made it difficult to import manufactured goods. Additionally, the destruction caused by the war, including the loss of railroads, bridges, and factories, further hindered the South's economic recovery. As a result, the South's economy was ruined after the Civil War.
