Background and Overview of the Civil War
The American Civil War began because of growing tensions between Northern and Southern states. The biggest disagreement involved slavery and whether it would continue expanding into new American territories.
The Southern economy depended heavily on plantation agriculture, especially cotton production, which relied on enslaved labor. Many Northern states had moved toward industrial development and increasingly opposed the expansion of slavery.
When Abraham Lincoln was elected president in 1860, several Southern states feared that slavery would be restricted. Eleven states eventually separated from the United States and formed the Confederate States of America.
The Union, made up of Northern states and loyal border states, fought to preserve the nation. Over four years of devastating battles, the war caused enormous loss of life and permanently changed American society.
History and Development of the Civil War
The Civil War officially started on April 12, 1861, when Confederate forces attacked Fort Sumter in South Carolina. This event marked the beginning of a conflict that would involve millions of soldiers and civilians.
During the early years, both sides believed they could achieve a quick victory. However, the war became longer and more destructive than expected. Battles such as Gettysburg, Antietam, and Vicksburg became major turning points.
In 1863, President Abraham Lincoln issued the Emancipation Proclamation, declaring freedom for enslaved people in Confederate-controlled areas. Although it did not immediately end slavery everywhere, it transformed the purpose of the war.
The final major Confederate surrender occurred when General Robert E. Lee surrendered to General Ulysses S. Grant at Appomattox Court House on April 9, 1865. Shortly afterward, the Confederacy collapsed, and the United States began the difficult process of rebuilding during the Reconstruction era.
