Topic 6.14: Continuity and Change in Period 6

Updated · For the May 2027 AP exam

AP US History Topic 6.14, Continuity and Change in Period 6, weighs how much industrialization changed the United States from 1865 to 1898. Railroad track tripled between 1870 and 1890, steel output grew more than fiftyfold, cities swelled with immigrants, and wage work spread. In 1893 historian Frederick Jackson Turner argued that the end of the frontier, noted in the 1890 census, closed the first period of American history. Much of the evidence points instead to the railroad, the factory, and the city as the main forces of change, though race, sex, and conquest still decided who shared in power.

The White City Period 6 in Review: How Much Did Industrialization Change America? (1865–1898)

President Cleveland pressed a gold telegraph key in 1893 and switched on the lights of Chicago’s fair. Frederick Jackson Turner told a meeting there that the frontier had closed, and the Midway sat just outside the white palaces.

Continuity and Change in Period 6 in two minutes

  • The 1890 census reported that the frontier line had broken up, and on July 12, 1893, Frederick Jackson Turner argued that free land made Americans practical, inventive, individualist, and democratic.
  • Evidence for change pointed to industry: railroad track tripled from 1870 to 1890, steel output grew more than fiftyfold, and Chicago grew from about 300,000 people to over a million by 1890.
  • Prices fell and real wages rose, but depressions in 1873 and 1893, child labor, and violent strikes showed uneven gains while the gap between rich and poor widened.
  • Immigration, the new middle class, department stores, and women's organizations changed daily life, while the 1893 World's Columbian Exposition in Chicago showed off electric light and the Ferris wheel.
  • Continuity remained: most Americans still lived in the country in 1890, and Jim Crow, Chinese exclusion, the Dawes Act, and women's lack of a national vote kept power unequal.
  • Government kept aiding business through land grants, tariffs, and injunctions, and the Panic of 1893 and the Pullman strike in 1894 raised the question of who the new economy served.
  • On the exam: expect continuity and change questions, often with a Turner stimulus; the period connects back to Reconstruction in Period 5 and forward to Period 7, which begins in 1890.

Topic 6.14 key terms

Industrialization

The shift from farms and workshops to machines, factories and railroads. Between 1865 and 1898 steel, oil, electricity and giant corporations drove it, and it changed how Americans worked, where they lived and what they bought.

World's Columbian Exposition

The 1893 world's fair in Chicago, held for the 400th anniversary of Columbus's voyage. It drew about 27 million admissions in six months and showed off American industry, electricity and city planning.

Gilded Age

The late 1800s, named for an 1873 novel by Mark Twain and Charles Dudley Warner. Gilded means covered in a thin layer of gold: dazzling growth and wealth on the surface, with poverty, corruption and inequality underneath.

Frontier thesis

Frederick Jackson Turner's 1893 argument that the moving edge of settlement, the frontier, shaped American democracy and character, and that its closing ended an era. Critics point out the land was not empty: it was taken from Native nations.

Frontier line

The western edge of settled land on census maps: the line where population fell below two people per square mile. It moved west with every census from 1790 to 1880. In 1890 the Census Office said it could no longer be drawn.

Corroborate

Back a claim up with evidence. If a source or fact supports the argument, you say so, and you say why.

Qualify

Show where a claim stops being true. The argument holds in some places, for some people, or for some years, and not others.

Modify

Rewrite the claim to fit the evidence. If the facts contradict part of the argument, change the claim.

Continuity and change

An AP way of reasoning about a period: show what stayed the same, show what changed, then judge how much changed overall.

Gospel of Wealth

Andrew Carnegie's argument that the rich owe society and should give their fortunes away in ways that benefit everyone. Universities and libraries were the classic gifts.

Real wages

Pay measured by what it can buy. When prices fall faster than pay, real wages rise even if the paycheck stays the same. Between 1865 and 1898 real wages rose for many workers, while the gap between rich and poor widened.

Urbanization

The growth of cities and the rising share of Americans who live in them. Between 1870 and 1890 the urban share rose from about 26% to about 35%, fed by farm families and immigrants.

Complexity

Making an argument that weighs change against continuity, or shows how one development affected different groups differently. A thesis with complexity says what changed, what didn't, and for whom.

Spoils system

Giving government jobs to loyal party workers as rewards. A disappointed job-seeker shot President Garfield in 1881, and Congress answered with the Pendleton Act (1883), which put some federal jobs under a merit exam (KC-6.3.II.A).

Panic of 1893

A severe depression that began in 1893 as railroads and banks failed. Hundreds of banks and thousands of businesses closed, millions of workers lost their jobs, and Washington offered no relief. Hard times lasted until about 1897 (KC-6.1.II.A).

Pullman Strike (1894)

A nationwide railroad boycott that began when Pullman's workers struck. Eugene Debs's American Railway Union refused to handle Pullman cars, and President Cleveland used a court order and federal troops to break the strike (KC-6.1.II.C).

Staff

The White City's 'marble': plaster of Paris and jute fiber, cast in molds and painted white over a timber or steel frame. It was cheap, fast to hang and only meant to last one season.

The Gold Key

May 1, 1893

Key terms: Industrialization, World's Columbian Exposition, Gilded Age, Frontier thesis

Promontory Summit, Utah Territory May 10, 1869

Western Union operator at Promontory

DONE.

Almost twenty-four years after DONE, another telegraph key sat on a table in Chicago.

It was an ordinary telegraph key. Except it was gold, and the button was ivory.

Grover Cleveland

As by a touch the machinery that gives life to this vast exposition is now set in motion…

Grover Cleveland, Address at the Opening of the World's Columbian Exposition, 1893-05-01

Across the grounds, the circuit started a giant steam engine in Machinery Hall.

Fountains leapt. Flags unrolled along the rooftops. A cloth dropped from a gilded Republic, sixty-five feet tall.

This was the World's Columbian Exposition, for the four hundredth anniversary of Columbus's voyage. It opened a year late.

People called it the White City. Almost none of it was built to last.

That summer, in a room downtown, a young historian said the frontier was gone. And with it, the first period of American history. Was he right?

The Line

1890–July 12, 1893

Key terms: Frontier line, Frontier thesis, Corroborate, Qualify, Modify

Every ten years, the census marked where settlement thinned to two people per square mile. That frontier line crept west for a century.

In 1890, the line broke into islands, and the Census Office said so.

Frederick Jackson Turner

…at present the unsettled area has been so broken into by isolated bodies of settlement that there can hardly be said to be a frontier line.

Frederick Jackson Turner, The Significance of the Frontier in American History, 1893-07-12

A new hall on Michigan Avenue, built for the fair's congresses. Hot. Frederick Jackson Turner, thirty-one, of Wisconsin, had a paper to read.

Several papers came first. Some listeners had spent the afternoon at Buffalo Bill's Wild West. They had already seen the frontier that day.

Frederick Jackson Turner

The existence of an area of free land, its continuous recession, and the advance of American settlement westward, explain American development.

Frederick Jackson Turner, The Significance of the Frontier in American History, 1893-07-12

Each new frontier, he argued, rebuilt settlers as practical, inventive, individualist and, above all, democratic Americans.

…the frontier has gone, and with its going has closed the first period of American history.

Frederick Jackson Turner, 1893

The room was unmoved. Within a generation, it was one of the most influential essays American historians had written.

Turner said the frontier made America. This unit pointed at the railroad, the factory and the city.

Test it three ways. Evidence can corroborate a claim, qualify it, or make you modify it.

Now test him.

Here's where this unit happened.

Almost every story in this unit left something at this fair.

An evening in September 1893. It costs fifty cents to get in. The fair also sells its own fifty-cent coin. For a dollar.

Carry Turner's sentence with you. At each lamp there's a piece of evidence. File it as change, continuity or both, and watch what it does to his claim.

Look at his sentence now. It's covered in your red pencil. That's an argument getting better.

Two Hundred Sixty-Four Feet

the same night, September 1893

Key terms: Gospel of Wealth, Real wages, Urbanization, Complexity

Daniel Burnham, who ran construction, wanted something to top the Eiffel Tower. A Pittsburgh bridge builder named George Ferris answered with a wheel.

Two hundred sixty-four feet high. Thirty-six cars, sixty riders each. Fifty cents a ride, on top of the fifty at the gate.

From up here, the change is easy to see. Most of these lamps run on Westinghouse's alternating current.

On the Midway's edge is the University of Chicago, opened last October with Rockefeller's money. Carnegie called that kind of giving the Gospel of Wealth.

Now look past the lights. That orange glow to the south is Illinois Steel's South Works. Farther on lies Pullman's company town.

West, the Union Stock Yards. North, a city of a million, where three in four people are immigrants or their children.

In these years prices fell and real wages rose. More children worked for wages. The gap between the richest and everyone else grew faster.

From 1870 to 1890 the population grew by more than half. Railroad track tripled. Steel output grew about sixtyfold. And most Americans still lived in the country.

Henry Adams

Chicago asked in 1893 for the first time the question whether the American people knew where they were driving.

Henry Adams, The Education of Henry Adams, ch. 22, 'Chicago (1893)', 1907 (published 1918)

Here's one answer. Industrialization changed America more than the frontier ever did: how people worked, where they lived, what they bought.

It changed much less about who held power. Race, sex and conquest still decided who shared in it.

That's complexity: what changed, what didn't, and for whom. Your version may use different evidence. It should.

Frederick Jackson Turner

…the American energy will continually demand a wider field for its exercise.

Frederick Jackson Turner, The Significance of the Frontier in American History, 1893-07-12

Down on the Midway, a round building holds a painted volcano, Kīlauea. Its promoter, Lorrin Thurston, helped overthrow Hawaii's queen that January.

Key terms: Spoils system, Panic of 1893, Pullman Strike (1894), Staff, Gilded Age

The fair was supposed to close with a grand ceremony on October 30. It never happened.

Carter H. Harrison

Mayor of Chicago · 1825–1893

Two nights before, a man shot Mayor Carter Harrison dead. He believed the mayor owed him a city job. Twelve years earlier, a disappointed office-seeker had killed President Garfield.

That winter, jobless men slept on the stone floors of police stations and City Hall. Some found shelter in the empty palaces.

In May 1894, Pullman's workers struck. Their wages had been cut by about a quarter. Their rents hadn't.

In July, fourteen months after he pressed the gold key, President Cleveland sent federal troops into Chicago.

On the evening of July 5, fire broke out in the empty fairgrounds. Nobody ever proved who started it.

Most of the Court of Honor burned that night. A huge crowd watched from the shore, as if it were one last show.

The white skin was staff, plaster and jute fiber painted to look like marble. It fell away in sheets. Underneath, the big halls' steel frames still stood.

By morning, the palaces were charred wood, blackened plaster and bent steel.

Above the ruins, the gilded Republic still stood.

Twain and Warner called this era the Gilded Age: a thin coat of gold over something cheaper. The White City was a Gilded Age you could walk through.

But the steel under the plaster was real. So was the question the fair never answered: who was all of this for?
