The American Civil War
The American Civil War (1861-1865) was fought between the northern and southern United States, primarily over the issue of slavery and state
Core concept
The war began after southern states seceded (withdrew) from the United States, largely over disagreements about slavery and its expansion into new territories.
How it works
President Abraham Lincoln led the northern states (the Union) against the southern Confederacy, which wanted to preserve slavery and state independence.
Why it matters
The Emancipation Proclamation in 1863 declared enslaved people in Confederate states to be free, marking a turning point in the war's purpose.
Key detail
The Union's victory in 1865 preserved the United States as one country and led to the abolition of slavery throughout the nation.
