What was the primary objective of the Civil War blockade?

• A. To prevent Confederacy from exporting cotton and importing goods
• B. To enforce allied port control
• C. To protect Union supply lines by land
• D. To expand territorial water rights

Answer: (A)

The main idea behind the blockade was to choke the Confederacy by cutting off its sea-borne trade, especially preventing cotton from being exported and imports of goods and war materiel from getting in. By sealing off southern ports along the Atlantic and Gulf coasts, the Union aimed to deny the Confederacy hard currency from cotton and cripple its ability to obtain weapons, food, and other essential supplies, speeding up the war’s end. The other options don’t capture this economic-strangulation purpose—the blockade wasn’t about enforcing allied port control, protecting land supply lines, or expanding water rights.
