Slavery and the Civil War
Grade 4 · Social Studies · Study Guide
Understand the institution of slavery, why it divided the nation, and how the Civil War ended it.
Slavery — the ownership of human beings as property — is one of the darkest chapters in American history. From the earliest colonial days through 1865, millions of enslaved Africans and their American-born descendants were forced to work without pay, were bought and sold like objects, and had their most basic human rights denied. Understanding this history honestly is essential to understanding the United States.
By the mid-1800s, slavery had become the central point of conflict between Northern and Southern states. The South's plantation economy depended on enslaved labor to grow cotton and other crops. As new states were added to the country, the question of whether they would allow or prohibit slavery threatened to tear the nation apart. Enslaved people themselves resisted in countless ways — through work slowdowns, running away, secret schools, maintaining cultural traditions, and outright revolts. Harriet Tubman, who escaped slavery herself, led around 70 people to freedom through the Underground Railroad, a secret network of safe houses.
When Abraham Lincoln was elected president in 1860, many Southern states believed he would end slavery. Before he was even inaugurated, eleven Southern states seceded — left the Union — and formed the Confederate States of America. The Civil War began in April 1861 when Confederate forces attacked Fort Sumter in South Carolina. For four devastating years, the Union (North) and Confederacy (South) fought in the bloodiest war in American history — over 600,000 soldiers died.
In January 1863, Lincoln issued the Emancipation Proclamation, declaring that all enslaved people in Confederate states were free. This changed the war's purpose: it was now explicitly a fight to end slavery. The Union won the war in April 1865. The Thirteenth Amendment to the Constitution, ratified that December, officially abolished slavery everywhere in the United States.

Show answer
Answer: They feared Abraham Lincoln would end slavery
Abraham Lincoln opposed the expansion of slavery into new territories. Southern slaveholders feared his election meant the eventual end of slavery, which their economy depended on. Eleven states seceded before Lincoln was even inaugurated.
The Emancipation Proclamation abolished slavery everywhere in the United States.
Show answer
Answer: False
The Emancipation Proclamation only freed enslaved people in Confederate (rebel) states. It did NOT free enslaved people in border states that remained in the Union. The Thirteenth Amendment (1865) abolished slavery everywhere.
What did the Thirteenth Amendment do?
- It gave women the right to vote
- It officially abolished slavery throughout the United States
- It made Confederate soldiers citizens again
- It gave formerly enslaved people the right to vote
Show answer
Answer: It officially abolished slavery throughout the United States
The Thirteenth Amendment, ratified on December 6, 1865, officially abolished slavery and involuntary servitude everywhere in the United States, completing what the Civil War began.
Harriet Tubman used the ___ Railroad to lead enslaved people to freedom.
Show answer
Answer: Underground
The Underground Railroad was not a real railroad — it was a secret network of people and safe houses that helped enslaved people travel north to freedom. Harriet Tubman was its most famous 'conductor.'
The Civil War was the deadliest war in American history.
Show answer
Answer: True
The Civil War (1861-1865) killed approximately 620,000-750,000 soldiers — more Americans than died in World War I and World War II combined. It remains the deadliest conflict in U.S. history.
Fun facts
- Harriet Tubman made about 13 trips back into slave states after her own escape and never lost a single 'passenger' on the Underground Railroad — earning her the nickname 'Moses.'
- The Battle of Gettysburg in July 1863 was the deadliest battle of the Civil War — over 51,000 soldiers were killed, wounded, or went missing in just three days.
