Before this unit
Locate the period and region on your timeline and map. Define unfamiliar terms using the explanations; revisit the preceding unit when a connection is unclear.
Use three flexible 45–60-minute sessions: background and Parts 1–2; Parts 3–4 and the worked evidence case; then independent practice, revision, and the exit check. If reading or writing needs longer, use the parent plan’s flexible sessions. Workshop, review, quiz, and examination time is separate.
By the late nineteenth century, U.S. production, trade, naval planning, and political influence extended beyond continental territory. Supporters of expansion sought markets and strategic bases and sometimes used racial or cultural hierarchies to justify rule. Critics challenged costs, consent, and the contradiction with self-government.
People in Hawaii, Latin America, Asia, and the Pacific had their own governments, movements, and aims. They were not merely settings for U.S. decisions. Distinguish trade, diplomatic influence, military intervention, annexation, and colonial rule.
A naval base enables refueling, repair, and movement; a market offers customers; a colony involves political control. An expansionist argument could combine these aims with claims about cultural superiority. Anti-imperialists challenged rule without consent, but some also opposed expansion for exclusionary reasons. In China, the Open Door proposals sought commercial access amid competing outside powers rather than annexation by the United States. In the Caribbean, U.S. intervention and financial influence took different forms. The key question is how an arrangement changed authority, not simply whether a U.S. flag appears on a map.
The 1898 war with Spain was followed by distinct outcomes in Cuba, Puerto Rico, Guam, and the Philippines. Cuban formal independence did not eliminate U.S. intervention powers imposed through the Platt Amendment arrangement. Filipino independence aims conflicted with U.S. annexation, producing the Philippine-American War. Hawaii’s earlier overthrow and 1898 annexation followed a different sequence. Trade, naval strategy, racism, and competing arguments about consent shaped these policies; the language of liberation did not establish identical self-government for every territory.

Part 1 · Identify different forms of power
Trade exchanges goods; diplomacy negotiates relationships; intervention uses power within another society; annexation claims territory as part of a state. A country can exercise influence without annexing territory. These distinctions clarify what changed for affected people.
Economic interests, naval strategy, domestic politics, and ideology could interact. A stated reason may be sincere but incomplete. Compare private correspondence, public arguments, local accounts, and policy outcomes before assigning a single motive.
Annexation changes claimed sovereignty, a protectorate arrangement constrains decisions without identical incorporation, and economic influence works through other relationships. Trace treaty provisions, local authority, and military capacity. A nation’s largest territorial map cannot establish consent, constitutional status, or equal political membership.

Part 2 · Understand Hawaii through local history
Hawaii was an independent kingdom before U.S. annexation. In 1893 a group opposed to the monarchy overthrew Queen Liliʻuokalani with involvement by U.S. representatives and forces. Annexation followed in 1898, amid Hawaiian opposition and competing interests.
A strategic harbor or profitable crop explains why outsiders valued a place, not why its people consented. Native Hawaiian petitions and accounts help reveal political aims that an expansionist map may omit. Do not describe annexation as an uncontested gift.
The overthrow of the Hawaiian monarchy in 1893 and U.S. annexation in 1898 are different events with different actors and legal instruments. Native Hawaiian opposition and continuing community life matter to evaluating claims of unanimous consent. A later annexation date does not explain the entire local political history.
Pause and explain
Why should Hawaii’s 1893 overthrow and 1898 annexation be treated separately?

Part 3 · Examine canals and intervention
The Panama Canal opened in 1914 and shortened maritime routes. Its construction followed Panama’s separation from Colombia and U.S. acquisition of control over a canal zone. Engineering achievements and disputes over sovereignty belong in the same account.
The Roosevelt Corollary asserted a U.S. role in intervention in the Americas. Supporters invoked stability and protection of interests; affected societies challenged outside control. A stated protective aim does not establish that consequences were beneficial or consented to.
The Panama Canal combined strategic and commercial interests with interventions and treaty arrangements. A transportation benefit does not by itself justify every action used to secure it. Identify whose authority changed and compare official purposes with affected communities’ experiences.

Part 4 · Compare imperial and anti-imperial arguments
Some Americans argued that overseas rule would promote security and commerce; anti-imperialists objected to governing people without consent. Opposition itself varied and could also contain racial exclusions. A shared conclusion does not mean identical reasoning.
Include the political goals of affected people rather than reducing debate to two U.S. positions. Test claims with consequences and sources, and distinguish explaining a historical rationale from accepting its racial assumptions.
Anti-imperialists disputed annexation on constitutional, moral, strategic, and sometimes racist grounds; opposing empire did not guarantee support for racial equality. Imperial supporters also advanced multiple arguments. Analyze the particular claims instead of assuming each camp had one identical position.
Pause and explain
Why should anti-imperialism not automatically be equated with support for racial equality?

Apply the whole unit · Distinguish interests from consent
Teaching summaries, not quotations: a naval planner favors an island base; a merchant expects trade gains; a local petition objects to foreign rule.
Your task
Identify each perspective and explain which evidence addresses strategic interest and which addresses political consent.
What your response should show
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Response guidance — after your attempt
The planner and merchant explain outside interests.
The petition documents an objection by its signatories, not necessarily every resident.
Investigate local authority, competing views, and conditions of decision-making.
The sources address different questions. Strategic or commercial gains do not answer whether local people consented. The petition matters but should be situated among local institutions and other evidence rather than treated as a complete census of opinion.
Historical references for this unit
Parent / teacher teaching notes
Ask for a causal explanation and a source limitation, then give specific feedback. Permit notes, a glossary, oral responses, or an outline before independent writing. Mark accuracy and evidence, not the learner’s religion, cultural identity, or agreement with a political opinion. Extend study rather than rushing the full unit into one class.
The key idea
People in Hawaii, Latin America, Asia, and the Pacific had their own governments, movements, and aims. They were not merely settings for U.S. decisions. Distinguish trade, diplomatic influence, military intervention, annexation, and colonial rule.
Worked examples
Example 1 · Worked evidence case
- The planner and merchant explain outside interests.
- The petition documents an objection by its signatories, not necessarily every resident.
- Investigate local authority, competing views, and conditions of decision-making.
Example 2 · Transfer reasoning: compare after your attempt
- Identify the relevant period, institution, and evidence.
- No. Their postwar arrangements differed, and Filipino independence aspirations collided with U.S. annexation. Compare the treaty, local governments, military action, and later restrictions. One war and a shared liberation slogan do not establish one universal outcome.
Avoid these mistakes
- Treating a whole community as one actor.
- Confusing a source’s assertion with an established fact.
- Assuming chronology alone establishes a cause.
- Treating unsupported denial as equally credible evidence.
