Pro-Imperialists

Pro-Imperialists were Americans in the 1890s who argued the U.S. should expand overseas, citing economic opportunities, racial theories like Social Darwinism, competition with European empires, and the 'closing' of the Western frontier as reasons to spread American culture and institutions abroad.

What are Pro-Imperialists?

Pro-Imperialists were the people pushing the United States to grab territory and influence beyond North America in the late 1800s and early 1900s. Their core claim was that America was destined to expand its culture, institutions, and economic reach to peoples around the globe. Think of them as Manifest Destiny supporters who ran out of continent and looked across the ocean instead.

The CED (KC-7.3.I.A) gives you their four big arguments, and you should know all of them. First, economic opportunity. New territories meant new markets for American goods and raw materials for American factories. Second, racial theories. Many pro-imperialists used Social Darwinist logic to claim Anglo-Saxon civilization was superior and had a duty to 'uplift' other peoples. Third, competition with European empires. Britain, France, and Germany were carving up Africa and Asia, and pro-imperialists feared the U.S. would be left behind. Fourth, the perception that the Western frontier had 'closed' by the 1890s, which made expansionists look overseas for the next frontier. Their wins included annexing Hawaii in 1898 and taking the Philippines, Puerto Rico, and Guam after the Spanish-American War.

Why Pro-Imperialists matter in APUSH

This term lives in Topic 7.2 (Imperialism: Debates) in Unit 7, and it directly supports learning objective APUSH 7.2.A, which asks you to explain similarities and differences in attitudes about America's proper role in the world. That phrasing matters. The exam doesn't just want you to know that imperialists existed; it wants you to set their arguments against the Anti-Imperialists' arguments (self-determination, isolationist tradition) and notice the overlap. Here's the twist worth remembering: both sides used racial theories. Pro-imperialists said racial superiority justified ruling other peoples, while some anti-imperialists said racial difference was a reason not to absorb them. That kind of nuance is exactly what comparison-style MCQs and FRQs reward. The debate also connects to the America in the World theme, which threads through the whole course.

How Pro-Imperialists connect across the course

Anti-Imperialists (Unit 7)

The other half of the Topic 7.2 debate. Anti-Imperialists countered every pro-imperialist argument with self-determination and the isolationist tradition. You can't fully explain one side without the other, since LO 7.2.A is literally a compare-and-contrast objective.

Manifest Destiny (Unit 5)

Pro-imperialism is Manifest Destiny 2.0. The same belief in a divinely sanctioned mission to spread American civilization that drove westward expansion in the 1840s got redirected overseas once the frontier was seen as closed. That's a ready-made continuity argument for a long essay.

Social Darwinism (Unit 6)

The 'survival of the fittest' logic Gilded Age elites used to justify industrial inequality also armed pro-imperialists with a 'scientific' case for ruling supposedly weaker peoples abroad. Same idea, different target.

Hawaii (Unit 7)

Hawaii is the pro-imperialists' concrete win. American planters overthrew the Hawaiian monarchy in 1893, and annexation followed in 1898. If an FRQ asks for evidence of imperialist attitudes shaping policy, this is your go-to example.

Are Pro-Imperialists on the APUSH exam?

No released FRQ has used 'pro-imperialists' verbatim, but the imperialism debate itself is classic exam territory. MCQs often hand you an excerpt from someone like Albert Beveridge or Josiah Strong and ask which argument it reflects or which group would have opposed it. Your job is to recognize the four pro-imperialist justifications (economics, racial theories, European competition, closed frontier) and match them to a side. For FRQs and the DBQ, this term works two ways. In a comparison task, you contrast imperialist and anti-imperialist views of America's world role. In a continuity-and-change task, you trace expansionist ideology from Manifest Destiny through 1890s imperialism, which is a sophisticated move that can help earn the complexity point.

Pro-Imperialists vs Anti-Imperialists

These are opposing sides of the same 1890s debate, and the exam loves making you sort their arguments. Pro-Imperialists wanted overseas expansion and cited economic markets, racial superiority, European competition, and the closed frontier. Anti-Imperialists opposed taking overseas territory and cited self-determination and America's isolationist tradition. The trap is the racial-theory overlap. Both sides invoked race, just to opposite conclusions, so don't assume a racial argument in a source automatically means it's pro-imperialist.

Key things to remember about Pro-Imperialists

  • Pro-Imperialists supported U.S. overseas expansion in the 1890s and believed America was destined to spread its culture and institutions worldwide.

  • Their four CED-backed arguments were economic opportunities, racial theories, competition with European empires, and the perceived closing of the Western frontier.

  • Pro-imperialism is essentially Manifest Destiny redirected overseas, which makes it a strong continuity argument across Units 5 through 7.

  • Both Pro-Imperialists and Anti-Imperialists used racial theories, but they reached opposite conclusions about whether the U.S. should rule other peoples.

  • The annexation of Hawaii in 1898 and the territories gained from the Spanish-American War are the clearest evidence of pro-imperialist arguments winning out in policy.

Frequently asked questions about Pro-Imperialists

What did Pro-Imperialists believe in APUSH?

They believed the U.S. should expand its territory and influence overseas, arguing that economic markets, racial superiority, competition with European empires, and the closed Western frontier made expansion both necessary and destined.

Were all Pro-Imperialists motivated by money?

No. Economic opportunity was one motive, but the CED lists three others: racial theories about civilizing 'inferior' peoples, fear of losing out to European empires, and anxiety over the frontier being 'closed' in the 1890s. Many imperialists genuinely saw expansion as a moral or religious mission.

How were Pro-Imperialists different from Anti-Imperialists?

Pro-Imperialists wanted overseas expansion and cited economics, race, and great-power competition. Anti-Imperialists opposed it, citing self-determination and the isolationist foreign policy tradition. Watch out: both sides used racial arguments, just for opposite conclusions.

Is pro-imperialism the same thing as Manifest Destiny?

Not exactly, but they're closely related. Manifest Destiny justified continental expansion in the mid-1800s, while 1890s pro-imperialism applied the same logic to overseas territories like Hawaii and the Philippines after the frontier was seen as closed. The exam rewards you for connecting them as a continuity.

What territories did Pro-Imperialists help the U.S. acquire?

Their biggest wins came in 1898, when the U.S. annexed Hawaii and took the Philippines, Puerto Rico, and Guam after the Spanish-American War. These acquisitions are your best specific evidence for FRQs on imperialist attitudes shaping policy.
