North and South around 1845
In 1845 the USA was one country with two ways of life.
- The North had growing cities, factories, canals and railways. Workers were paid wages. Many immigrants from Ireland and Germany arrived.
- The South lived mostly by farming. Cotton was its biggest crop and the world's mills wanted it. Large farms called plantations used enslaved people: people who were bought, sold and forced to work for no pay. By 1860 about 4 million people were enslaved.
A growing abolitionist movement (people who wanted slavery ended) included writers like Frederick Douglass, who had escaped slavery himself. Many Southerners saw slavery as the base of their economy and argued for states' rights: each state should decide for itself.
Comparing the two regions
North: more people, industry, free labour, more railways. South: farming, enslaved labour, fewer cities. Both shared the same constitution, which is why the fight was about how far the national government could go.
Growing west: Manifest Destiny and the Mexican–American War
Manifest Destiny was a popular belief in the 1840s that the USA was meant to spread across the whole continent to the Pacific. In 1845 Texas joined the USA. A border dispute led to the Mexican–American War (1846–48). Mexico lost, and the USA took a huge area in the south-west, including California.
This growth had a cost: Native American nations were pushed off their lands, and Mexico lost about half its territory. It also re-opened the hardest question: would slavery be allowed in the new lands?
Attempts to keep the Union together, and why they failed
In the Senate each state has two votes. If free states outnumbered slave states, laws could end slavery, so each side watched the balance closely.
- Missouri Compromise (1820): Missouri entered as a slave state, Maine as a free state, and a line was drawn for future land.
- Compromise of 1850: California entered as a free state; the slave trade (not slavery) ended in Washington DC; but a strict Fugitive Slave Act forced Northerners to help return people who escaped slavery. Many Northerners were angered.
- Kansas–Nebraska Act (1854): settlers would vote on slavery ("popular sovereignty"). Both sides rushed in and fighting broke out ("Bleeding Kansas"). The new Republican Party formed to stop slavery spreading west.
- Dred Scott decision (1857): the Supreme Court said Black people could not be citizens and Congress could not ban slavery in territories. Compromise now seemed impossible.
- John Brown's raid (1859) on Harpers Ferry frightened the South.
1860: Lincoln's election and secession
In 1860 the Democrats split in two, and Abraham Lincoln (Republican) won without a single Southern state. He promised not to touch slavery where it existed but to stop it spreading. South Carolina left the Union in December 1860. Ten more followed. Leaving is called secession. The 11 states formed the Confederate States of America. In April 1861 Confederate guns fired on Fort Sumter, and the war began.
The war, 1861–1865
The Union (North) had about 71% of the people, about 90% of the factories and most of the railways. The Confederacy (South) had strong generals such as Robert E. Lee and fought on home ground.
- Strategy: the North blockaded Southern ports and tried to split the South along the Mississippi River.
- Turning points (1863): victories at Gettysburg and Vicksburg.
- Emancipation Proclamation (1 January 1863): Lincoln declared enslaved people in rebel areas free. About 180,000 Black soldiers then joined the Union army.
- Government policies: both sides used conscription (forced army service); the North printed paper money, raised an income tax and built a transcontinental railway.
- End: Lee surrendered at Appomattox in April 1865. Days later Lincoln was assassinated. About 620,000 soldiers died, more than in any other American war.
Reconstruction, 1865–1877, and why it failed
Reconstruction means rebuilding the South and bringing it back into the Union.
Early Reconstruction (1865–67)
President Andrew Johnson was lenient with former Confederates. Southern states passed Black Codes, laws that limited where freed people could work and travel.
Radical Reconstruction (1867–77)
Congress took control. The army supervised the South. Three amendments were added:
- 13th (1865): slavery ended.
- 14th (1868): everyone born in the USA is a citizen, with equal protection of the laws.
- 15th (1870): the vote cannot be denied because of race (only men voted then).
The Freedmen's Bureau opened schools; Black men were elected to Congress for the first time.
Why it failed
- Violent groups like the Ku Klux Klan attacked Black voters.
- Freed people got no land, so most became sharecroppers, paying rent with part of their crop and staying poor.
- The North lost interest after an economic crash in 1873.
- The Compromise of 1877 removed the last troops. Southern states then passed segregation ("Jim Crow") laws, which lasted until the civil rights movement of the 1950s–60s.
Try it
In the 3D free-play step, set the year to 1850, then 1861, then 1877. For each, write one sentence: what does the balance of blocks show, and which amendment pillars exist? Then make a two-column table at home: "Reasons the North won" and "Reasons Reconstruction failed". Try to find at least three for each.
Key formulas and definitions
- Secession: a state leaving the Union
- Abolitionist: a person who wanted slavery ended
- Manifest Destiny: the belief that the USA should spread across the continent
- Popular sovereignty: settlers voting whether to allow slavery
- Emancipation: setting enslaved people free
- Reconstruction: rebuilding the South and the Union, 1865–1877
- Sharecropping: farming someone else's land and paying with part of the crop
- Jim Crow laws: later Southern laws that kept Black and white people separate
Worked examples
1. Put in order: Kansas–Nebraska Act, Compromise of 1850, Lincoln elected, Dred Scott decision.
Compromise of 1850 → Kansas–Nebraska Act (1854) → Dred Scott decision (1857) → Lincoln elected (1860).
2. Give two economic reasons why the North won the war.
1) It had about 90% of the factories, so it could make more guns and supplies. 2) It had more railways to move soldiers and food. (Also: about 71% of the people.)
3. Why did the Compromise of 1850 make tensions worse, not better?
Its Fugitive Slave Act forced Northerners to help capture people escaping slavery. This brought slavery into Northern towns and turned many neutral Northerners against the South.
4. Explain one reason Reconstruction is said to have failed.
Freed people did not receive land. Most became sharecroppers who stayed in debt to landowners, so they had freedom on paper but little economic independence.
Common mistakes
- Saying the war was only about "states' rights". The right the Southern states were defending above all was the right to keep slavery.
- Thinking the Emancipation Proclamation freed all enslaved people. It applied to rebel areas; the 13th Amendment (1865) ended slavery everywhere.
- Mixing up the amendments: 13 = freedom, 14 = citizenship and equal protection, 15 = voting regardless of race.
- Believing Reconstruction ended racial inequality. After 1877 Jim Crow laws and violence removed many rights for decades.
