In 1858, a few years before the war broke out, the U.S. is exporting much of the cotton into both Europe and Britain. But by 1864, one year into the war, it's nearly shut down. Though the states were still producing some cotton, they were hardly exporting it. China responds by massively increasing the quantities they're sending west. The war ends in the spring of 1865, imports from the U.S. spike. But by this time, plantations in Egypt are now sending a good chunk of cotton, and China continues to hold a strong place in the world's cotton trade. The war has changed things and, as infographic historian R.J. Andrews explains in a video, Minard's series beautifully captures one aspect of the fight.
