What occurred in the Civil War?
The American Civil War (April 12, 1861–May 9, 1865) became a civil battle within the United States between the Union and the Confederacy.
The valuable motive of the battle became the reputation of slavery, especially the enlargement of slavery into territories received because of the Louisiana Purchase and the Mexican–American War.
On the eve of the Civil War in 1860, 4 million of the 32 million Americans (13%) had been enslaved black people, nearly all within the South.
The exercise of slavery within the United States became one of the key political problems of the nineteenth century. Decades of political unrest over slavery led to as much as the Civil War.
A preliminary seven southern slave states declared their secession from the USA to shape the Confederacy. Confederate forces seized federal forts inside territory they claimed.
Fighting broke out in April 1861 when the Confederate military started the Battle of Fort Sumter in South Carolina, simply over a month after the primary inauguration of Abraham Lincoln.
