Causes of the Civil War (slavery, secession, political breakdown)
The course and experience of the Civil War (military strategy, emancipation)
Social impacts: Black Americans, women, soldiers
Reconstruction (Presidential vs. Radical)
Rise and collapse of Black civil rights
Political resistance and white supremacy
The nation teetered on the edge. When Lincoln, a relatively unknown Illinois lawyer, won with no Southern electoral votes, the South felt overrun by abolitionist mobs and “Yankee tyrants.” South Carolina—like a match to dry leaves—seceded first. Mississippi, Alabama, Georgia, and others followed. One by one, they renounced the Union and declared their own nation: The Confederate States of America, rooted openly in the preservation of slavery.
Why it matters: Lincoln didn’t even appear on most Southern ballots. The entire political system had failed to resolve the nation’s core moral contradiction—slavery.
Charleston Harbor. April 12. Confederate cannons roared to life, shelling Fort Sumter. The Union soldiers held out for 34 hours, but were forced to surrender. Lincoln responded by calling 75,000 volunteers to suppress the “rebellion.”
Why it matters: The Civil War had begun—not just to save the Union, but to decide the fate of slavery and democracy itself.
General Winfield Scott’s plan was a slow, strategic chokehold: blockade the South, control the Mississippi River, and crush the Confederacy like a serpent wrapping tighter and tighter.
Civilians watched with picnic baskets, expecting a quick Union win. But Confederate forces, led by the resolute “Stonewall” Jackson, sent Union troops fleeing. Reality struck: this would not be a short war.
Why it matters: Psychological turning point. Both sides now understood they were in for a long, bloody slog.
Black men, women, and children began fleeing to Union lines, forcing the North to confront slavery. General Butler classified them as “contraband of war,” and the First Confiscation Act allowed their seizure from the Confederacy.
After the bloody but inconclusive Battle of Antietam, Lincoln seized the moment. He issued the Emancipation Proclamation, freeing all slaves in rebelling territories. It didn’t free slaves in border states—but it transformed the war into a moral crusade.
“If I could save the Union without freeing any slave I would do it…” – Lincoln (earlier)
But now? Now it was about freedom and Union.
Imagine thunder crashing over fields soaked in blood. In three days of brutal fighting, 51,000 soldiers fell. Pickett’s Charge—Confederate men storming uphill into Union gunfire—was a doomed, heroic suicide mission. Lee retreated. The North cheered.
Why it matters: Major Confederate loss. Momentum shifted permanently.
Grant captured the fortress city of Vicksburg after a siege that starved the Confederates. This gave the Union full control of the Mississippi River, slicing the Confederacy in two.
In New York City, Irish immigrants—furious that the war had become about freeing slaves—rioted violently over the draft. They burned down the Colored Orphan Asylum and lynched Black citizens.
Why it matters: Racial and economic divides in the North were explosive. Not all Northerners were anti-slavery.
General Grant ground down Lee in the Overland Campaign, while General Sherman burned his way from Atlanta to Savannah. Crops? Burned. Railroads? Torn up. It was psychological warfare.
“War is cruelty, and you cannot refine it.” – William Tecumseh Sherman
Despite exhaustion and death tolls, Lincoln won re-election against George McClellan. Sherman’s success in Atlanta saved his chances. The Union’s cause was reaffirmed.
Lee, ragged and surrounded, surrendered to Grant. The scene was quiet, respectful—two generals ending a cataclysm. The war was over.
Why it matters: The Union was preserved. But what of the four million freedmen?
At Ford’s Theatre, John Wilkes Booth fired into the back of Lincoln’s head. The war’s greatest martyr fell, just as peace arrived.
Lincoln’s 10% Plan: Quick, easy reintegration.
Johnson’s Plan: Lenient toward ex-Confederates, allowed Black Codes.
Radical Republicans (like Thaddeus Stevens) pushed hard for civil rights.
13th: Abolished slavery (except as punishment).
14th: Guaranteed citizenship and equal protection.
15th: Granted Black men the right to vote.
Why it matters: This was America’s Second Founding—a legal revolution. But it would be challenged immediately.
Southern states passed laws keeping freedpeople in quasi-slavery. Vagrancy laws, labor contracts, violence.
Terror campaigns exploded across the South. The Ku Klux Klan lynched and beat freedmen and white allies. The Enforcement Acts tried to stop them—but federal resolve was weak.
For the first time, Black Americans served in state legislatures and Congress (e.g., Hiram Revels, Blanche K. Bruce). Public schools, welfare, and voting rights expanded.
Panic of 1873 weakened Northern focus on the South.
Democrats regained Southern statehouses (the “Redeemers”).
The Compromise of 1877 ended Reconstruction in exchange for Republican victory in a disputed election.
Why it matters: The federal government withdrew troops, and Jim Crow segregation took root. Black civil rights were crushed for the next century. - **Panic of 1873**: This economic crisis diverted the North's attention and resources away from Reconstruction efforts in the South. With businesses failing and unemployment rising, Northerners became more focused on economic recovery than on protecting the rights of Black citizens in the South. - **Democrats Regain Southern Statehouses (The “Redeemers”)**: As Northern support for Reconstruction waned, Southern Democrats, often referred to as "Redeemers," gradually regained control of state governments in the South. They employed various tactics, including intimidation and violence, to suppress Black voters and restore white supremacy.
Abraham Lincoln: War-time president, issued Emancipation, assassinated.
Jefferson Davis: Confederate president.
Ulysses S. Grant: Union general, later president.
Robert E. Lee: Confederate general, surrendered at Appomattox.

🟥 Emancipation was gradual, messy, and politically strategic.
🟩 Reconstruction was a revolutionary attempt to build a multiracial democracy—but it was crushed by white supremacist violence and Northern fatigue.

Rapid industrialization and monopolies
Labor struggles and union movements
Immigration and urban growth
Westward expansion and Native displacement
Corruption and political machines
Rise of populism and economic inequality
Picture America ablaze with steel and sparks. After the Civil War, industry exploded: railroads stitched the nation together like iron veins, and factories churned out goods in staggering quantities. Cities like Chicago, Pittsburgh, and New York rose like steel titans.
Steel (Bessemer process)
Oil (Rockefeller’s Standard Oil)
Railroads (Vanderbilt, transcontinental link in 1869)
Electricity and telegraphs: Edison's light bulb, Bell’s telephone
Why it matters: The U.S. became the world’s industrial superpower—but wealth concentrated in the hands of a few "captains of industry" (or “robber barons,” depending who you ask).
The rise of monopolies led to significant economic disparities, as a handful of individuals controlled vast resources and wealth.
Figures such as John D. Rockefeller in oil and Andrew Carnegie in steel exemplified how these industrialists dominated their respective sectors, often at the expense of fair competition.
Andrew Carnegie (Steel, “Gospel of Wealth”): He believed rich men should give away their fortunes.
John D. Rockefeller (Oil): Ruthlessly crushed competitors through horizontal integration.
J.P. Morgan (Banking): Bought Carnegie Steel and turned it into U.S. Steel.
These men used trusts, holding companies, and vertical/horizontal integration to control prices and crush competition.
“The man who dies rich dies disgraced.” – Carnegie
The factory floors were brutal—long hours, child labor, meager pay. Workers began to organize:
Knights of Labor: Wanted broad reforms—open to all workers.
American Federation of Labor (AFL): More conservative, skilled workers only.
Strikes & Protests:
Haymarket Riot (1886): Bombing in Chicago blamed on anarchists, ruined the Knights of Labor.
Homestead Strike (1892): Steelworkers vs. Carnegie’s guards—violence and defeat.
Pullman Strike (1894): Railroad strike crushed by federal troops under Eugene V. Debs.
Why it matters: The government sided with business over labor—showing the power imbalance in the Gilded Age.
Cities exploded—immigrants poured in from southern and eastern Europe (Italy, Russia, Poland). Tenements stacked families in airless cubes. Disease and crime festered in overcrowded slums.
Ellis Island (NYC) and Angel Island (SF): Immigrant processing centers
Nativism: Native-born Americans feared the “New Immigrants”
Chinese Exclusion Act (1882): First federal immigration restriction
Behind smoky taverns and behind-the-scenes deals stood the political machines, like Tammany Hall in NYC, led by Boss Tweed. In exchange for votes, they gave immigrants food, jobs, and help—then looted city treasuries.
Why it matters: Corruption flourished because local governments didn’t meet the needs of rapidly growing cities. Reform was slow and hard-fought.
While factories boomed in the East, the federal government opened the West for business—at great cost to Native peoples.
Homestead Act (1862): Free land for settlers
Transcontinental Railroad (1869): Finished at Promontory Point, Utah
Reservation System: Natives were forced into smaller and smaller areas
Wars and Resistance:
Battle of Little Bighorn (1876): Sitting Bull and Crazy Horse defeated Custer
Wounded Knee Massacre (1890): Hundreds of Lakota Sioux slaughtered—final blow to armed Native resistance
Farmers were crushed under debt, railroad rates, and falling prices. They fought back through the Grange Movement, then the Farmers’ Alliances, then the Populist Party.
Demanded:
Free silver (to inflate currency)
Graduated income tax
Railroad regulation
Direct election of senators
Their fiery voice: William Jennings Bryan, whose “Cross of Gold” speech electrified audiences in 1896.
"Free silver" meant allowing unlimited coinage of silver at a fixed ratio to gold (usually 16:1). At the time, the U.S. was on the gold standard, which meant every dollar was backed by a set amount of gold. This kept the money supply limited and favored bankers and big business.
Populists—mainly farmers and working-class Americans—wanted the government to mint more silver coins alongside gold, increasing the money supply.
Inflation would rise → More money in circulation = higher prices for crops = farmers could make more profit.
Debts would be easier to pay → If money was worth slightly less, farmers could pay back their loans with cheaper dollars.
Combat deflation → Prices were falling in the late 1800s, which crushed farmers. Free silver would reverse that trend.
Interstate Commerce Act (1887): Regulated railroads
Sherman Antitrust Act (1890): First attempt to break up monopolies (used more against labor!)
