The Civil War started in April 1861. The fighting began soon after Lincoln took over as the country’s new president.
Several Southern states tried to secede from the United States. They formed the Confederate States of America, or Confederacy. The Northern states were called the Union.
At the time, nearly 4 million enslaved people lived in the U.S. They or their ancestors had been taken from Africa.
Enslaved people had no rights or freedoms. They were forced to work without pay. Many enslaved people were forced to pick crops. Selling crops was how Confederate states made much of their money.
The Confederate states thought Lincoln would put an end to slavery in the U.S. They thought each state should have the right to make its own decision.
