Explanation:
The Civil War or the American Civil War was a war (although Congress never issued a Declaration of War) waged in the United States from 1861 to 1865. As a result, among other things, of a historical controversy over slavery and against attempts of the US federal executive to take powers that did not correspond to him in a constitutional manner, the war broke out in April 1861, when the forces of the Confederate States of America attacked Fort Sumter in South Carolina, shortly after President Abraham Lincoln took office. position. The nationalists of the Union proclaimed loyalty to the Constitution of the United States. They clashed with secessionists from the Confederate States, who defended the rights of states to expand slavery.
The entry into the war of the United Kingdom of Great Britain and Ireland or of France in favor of the Confederation would have greatly increased the possibilities of the South to gain independence from the Union. This, under the control of Lincoln and Secretary of State William Henry Seward, worked to prevent the European powers from getting involved. He threatened that, if they recognized the Confederation, this would amount to a declaration of war. Neither the United Kingdom nor France came, therefore, to recognize as legitimate the Confederate government.

This policy applied to cotton was totally ineffective, while the agricultural crisis in Europe from the years 1860 to 1862 increased the grain exports from the northern states to the Old World, since they were essential to avoid famines. It was said that "The Corn King was more powerful than the Cotton King" because the Union's cereals went from a quarter of the British imports to half of them.
