American Civil War

Following territorial growth, there was a strong development of transportation infrastructure, including canals and railroads. The south, which supported slavery, and the north, which opposed it, continued to disagree.

In the 1860 presidential election, Abraham Lincoln of the Republican Party, supported by the industrial bourgeoisie, won. The Republican Party's win in favor of the abolition of slavery infuriated slave owners and Southern states. They formally proclaimed the Confederacy of the United States of America and announced their break with the Union.

The American Civil War, which lasted from 1861 to 1865, was sparked by a dispute over the abolition of slavery between the Republican Party and the Southern states. The North was governed by the North after four years of brutal fighting. The Confederacy, led by General Robert E. Lee, was defeated under the direction of President Abraham Lincoln and General Ulysses S. Grant. The South wore out, but the Union was kept together. America abolished slavery.
