Overview
AMSCO Topic 7.2, "Imperialism: Debates," covers the argument Americans had in the late 1800s and early 1900s about whether the United States should expand beyond its borders and become a world power. This topic sits in Period 7 (1890-1945), and it sets up the foreign-policy story that runs through the Spanish-American War and into World War I. The big question: should the U.S. build an overseas empire the way European nations were doing, or stay out of it? Two camps formed, the imperialists and the anti-imperialists, and this chapter is about what each side believed and why.
This is a debate-focused topic, so the most useful thing you can do is learn the two positions clearly and be able to compare them. That comparison is exactly what the College Board wants you to be able to explain: the similarities and differences in how Americans thought about the country's proper role in the world.
Why the Imperialism Debate Happened in the 1890s
By the 1890s, several pressures pushed the United States to look outward for the first time in a serious way. Up to this point, American expansion had mostly meant moving west across the continent. Now that energy started pointing overseas.
Forces driving the conversation:
- The "closed frontier." By the 1890s, many Americans believed the western frontier was settled and "closed." If continental expansion was finished, where would the country's restless energy, growing population, and ambition go next? For a lot of people, the answer was overseas.
- Industrial overproduction. American factories and farms were producing more than the home market could buy. Business leaders wanted new foreign markets to sell goods and new places to invest money and get raw materials.
- Competition with European empires. Britain, France, Germany, and others were grabbing colonies across Africa and Asia. To many Americans, falling behind in this race felt like falling behind as a great power.
These pressures didn't automatically mean everyone wanted an empire. They just made the question impossible to avoid, which is what kicked off the debate.
The Imperialist Argument
Imperialists argued that the United States was destined to expand its culture, institutions, and influence to peoples around the globe. They leaned on a mix of economic, strategic, and racial reasoning.
Economic reasons
- New overseas markets would absorb surplus American goods.
- Foreign territory offered raw materials and places to invest capital.
- Growing trade required coaling stations, ports, and a strong navy to protect shipping.
Competition and national greatness
- Expansion would let the U.S. keep pace with European empires.
- Naval bases and territory abroad would project American power and strengthen national security.
- With the frontier "closed," overseas expansion was framed as the natural next chapter of American growth.
Racial and cultural theories
- Some imperialists used racial theories to claim that Anglo-Saxon Americans had a duty to spread their culture, government, and religion to other peoples.
- This argument cast expansion as a mission to "uplift" or "civilize," which assumed American institutions were superior and that other peoples needed American guidance.
That last point is uncomfortable but central. A big chunk of the imperialist case rested on the belief that Americans were destined and obligated to extend their way of life to others, an idea built on racial hierarchy.
The Anti-Imperialist Argument
Anti-imperialists argued that the United States should NOT extend its territory overseas. They thought taking colonies betrayed America's own founding principles. Their reasoning pulled from several directions, and (notably) some of it overlapped with the imperialists.
Self-determination and democratic principles
- Ruling over people who didn't consent to be ruled contradicted the American ideal that government rests on the consent of the governed.
- Holding colonies without giving those people full rights or citizenship looked like hypocrisy for a nation founded on liberty and self-government.
The isolationist tradition
- Anti-imperialists pointed to the long U.S. foreign-policy tradition of isolationism, the idea that America should avoid entanglements abroad.
- Staying out of overseas empire-building fit that tradition; building one broke from it.
Racial theories (used the other way)
- Here's the twist students often miss: some anti-imperialists also used racial theories, but to argue AGAINST expansion. They didn't want to absorb the populations of distant territories into the United States.
- So racial thinking showed up on BOTH sides of the debate, just pointed in opposite directions.
Comparing the Two Sides
The key skill for this topic is comparison, so line the two positions up directly.
| Issue | Imperialists | Anti-Imperialists |
|---|---|---|
| Overseas territory | Yes, the U.S. should expand abroad | No, the U.S. should not extend its territory overseas |
| Economics | New markets, raw materials, investment | Less central to their argument |
| European empires | Compete and keep up with them | Avoid imitating Europe; stay independent |
| The frontier | "Closed," so look overseas next | Not a reason to take colonies |
| Self-determination | Spreading U.S. institutions is a benefit | Ruling people without consent is wrong |
| Foreign-policy tradition | Time for America to be a world power | Stick with isolationism |
| Racial theories | Used to justify expansion ("uplift" others) | Used to oppose absorbing other peoples |
The big similarity
Both sides actually shared one thing: racial theories shaped the arguments on both ends. Imperialists used race to justify spreading American culture; anti-imperialists used race to justify keeping other peoples out. The conclusions were opposite, but the underlying assumptions about racial hierarchy showed up in both camps. That overlap is exactly the kind of nuance that earns points on a comparison question.
The big difference
The core split is simple: imperialists believed the United States was destined to expand its influence across the globe, while anti-imperialists believed expansion overseas violated the principles of self-determination and the tradition of isolationism. Everything else hangs off that one disagreement.

Frequently Asked Questions
What is AMSCO APUSH 7.2 about?
AMSCO Topic 7.2, "Imperialism: Debates," covers the late-1800s argument over whether the United States should expand overseas and become a world power. It lays out the imperialist case and the anti-imperialist case so you can compare how Americans viewed the nation's proper role in the world. For the course-topic version, see the 7.2 Imperialism: Debates study guide.
What did imperialists argue in the late 1800s?
Imperialists argued the U.S. was destined to expand its culture and institutions around the globe. They cited new economic opportunities (markets and raw materials), competition with European empires, the idea that the western frontier was "closed," and racial theories claiming a duty to spread American ways of life to other peoples.
What did anti-imperialists argue?
Anti-imperialists argued the U.S. should not extend its territory overseas. They cited the principle of self-determination, the foreign-policy tradition of isolationism, and (in some cases) racial theories used to oppose absorbing the populations of distant territories.
How did racial theories show up on both sides of the imperialism debate?
Racial theories appeared on both sides, just pointed in opposite directions. Imperialists used them to claim a duty to spread American culture to other peoples, while some anti-imperialists used them to argue against absorbing those populations. That shared assumption with opposite conclusions is a strong point to make on a comparison question.
How is the imperialism debate tested on the APUSH exam?
It's most often tested as a comparison, asking you to explain similarities and differences in how Americans viewed the country's role in the world. Be ready to lay out both the imperialist and anti-imperialist positions and point out the racial-theory overlap. You can practice this skill with FRQ practice with instant scoring.
