Answer:
Cotton export was disrupted during the Civil War.
France and Britain suffered from the disruption.
Step-by-step explanation:
Cotton export was the lifeline of the South and become the most valuable crop by exporting it to Europe to earn profit. The south produced two-thirds of the world's cotton. During the Civil War, the trade was disrupted as the Union wanted to close its port to break the economy and support from Europe.
France and Britain suffered from the disruption of trade. Southern plantations produced cotton, which used in the textile industry in Britain and France. Disrupting the cotton trade disturbed European textiles.
