What is the Treaty of Paris (1898)?

The Treaty of Paris (1898) is the peace agreement that officially ended the Spanish-American War. Spain gave up its claim to Cuba and handed over Puerto Rico and Guam to the United States. The U.S. also got the Philippines, paying Spain $20 million for the islands. In one document, America went from a country with no overseas colonies to an empire stretching from the Caribbean to the western Pacific.

That's exactly what the CED wants you to see (KC-7.3.I.C). The treaty produced three big effects you should be able to explain. First, the U.S. acquired island territories in both the Caribbean and the Pacific. Second, holding the Philippines pulled the U.S. much deeper into Asian affairs. Third, the acquisition triggered the suppression of a Filipino nationalist movement, because Filipinos led by Emilio Aguinaldo had been fighting Spain for independence and were not interested in trading one colonial ruler for another. The treaty also set off a huge debate at home between imperialists and anti-imperialists over whether a republic founded on consent of the governed could rule colonies. The Senate ratified it anyway in February 1899, by a narrow margin.

Why the Treaty of Paris (1898) matters in APUSH

This term lives in Topic 7.3 (The Spanish-American War) in Unit 7, and it's the payoff of learning objective APUSH 7.3.A, which asks you to explain the effects of the Spanish-American War. The war itself lasted only a few months; the treaty is where the consequences actually happen. It's your single best piece of evidence for the claim that the U.S. became a global imperial power around 1898, which connects directly to the America in the World theme. If a prompt asks about continuity and change in U.S. foreign policy from the 1890s into the 20th century, the Treaty of Paris is the hinge. Before it, expansion meant moving west across the continent. After it, expansion meant overseas colonies, naval bases, and deeper involvement in Asia and Latin America.

How the Treaty of Paris (1898) connects across the course

Spanish-American War (Unit 7)

The treaty is the war's ending and its consequences rolled into one. The fighting (think Manila Bay and Cuba) explains why Spain was forced to hand over its empire; the treaty explains what the U.S. did with the victory.

Philippine-American War (Unit 7)

The treaty caused this war. Emilio Aguinaldo's nationalists expected independence after Spain left, but the treaty made the Philippines a U.S. colony instead, so a brutal three-year insurrection followed. The CED flags this 'suppression of a nationalist movement' as a core effect of 1898.

Imperialism (Unit 7)

The treaty is imperialism made concrete. When you need specific evidence that the U.S. joined the European scramble for empire, naming Puerto Rico, Guam, and the Philippines from this treaty is the move.

Boxer Rebellion (Unit 7)

Owning the Philippines gave the U.S. a permanent foothold near China, which is why America jumped into Asian affairs like the Open Door policy and the response to the Boxer Rebellion just two years later.

Is the Treaty of Paris (1898) on the APUSH exam?

Multiple-choice questions hit this term directly. Fiveable practice questions ask things like 'Which treaty ended the Spanish-American War?' and 'Which territory did the U.S. acquire as a result of the Spanish-American War?' so you need the basic facts cold: 1898, Spain, Puerto Rico, Guam, the Philippines, and Cuban independence from Spain. Stimulus-based MCQs often pair the treaty with anti-imperialist speeches or political cartoons about 'taking up the white man's burden' and ask you to identify the debate over empire. No released FRQ has used the treaty's name verbatim, but it's prime evidence for LEQs and DBQs about U.S. foreign policy change around the turn of the century. The strongest exam move is using it to mark a turning point, then following the thread forward to the Philippine-American War and U.S. involvement in Asia.

The Treaty of Paris (1898) vs Treaty of Paris (1783)

Same name, completely different century. The Treaty of Paris (1783) ended the American Revolution and got the U.S. its independence from Britain (that's Unit 3 material). The Treaty of Paris (1898) ended the Spanish-American War and made the U.S. an empire by taking colonies from Spain. A quick way to keep them straight is that 1783 made America independent, while 1898 made America imperial. On the exam, the date or the war named in the stem tells you which one you're dealing with.

Key things to remember about the Treaty of Paris (1898)

  • The Treaty of Paris, signed December 10, 1898, officially ended the Spanish-American War between the United States and Spain.

  • Under the treaty, the U.S. acquired Puerto Rico, Guam, and the Philippines (paying Spain $20 million for the Philippines), and Spain gave up its claim to Cuba.

  • The treaty marks the moment the United States became an overseas imperial power, which is the core takeaway of KC-7.3.I.C and learning objective APUSH 7.3.A.

  • Taking the Philippines led directly to the Philippine-American War, because Filipino nationalists under Emilio Aguinaldo refused to accept a new colonial ruler.

  • Ratification sparked a major domestic debate between imperialists and anti-imperialists over whether a democratic republic should rule colonies without their consent.

  • Holding Pacific territory pulled the U.S. deeper into Asian affairs, setting up events like the Open Door policy and the response to the Boxer Rebellion.

Frequently asked questions about the Treaty of Paris (1898)

What did the Treaty of Paris (1898) do?

It ended the Spanish-American War on December 10, 1898. Spain gave up Cuba and transferred Puerto Rico, Guam, and the Philippines to the United States, with the U.S. paying $20 million for the Philippines.

Did the Treaty of Paris (1898) make Cuba a U.S. territory?

No. Spain gave up its claim to Cuba, but Cuba was not annexed like Puerto Rico, Guam, and the Philippines. The U.S. still dominated Cuba afterward through occupation and later the Platt Amendment, but Cuba was nominally independent.

How is the Treaty of Paris (1898) different from the Treaty of Paris (1783)?

The 1783 treaty ended the American Revolution and won U.S. independence from Britain. The 1898 treaty ended the Spanish-American War and gave the U.S. colonies taken from Spain. One created an independent nation; the other created an empire.

Why did the Treaty of Paris (1898) lead to the Philippine-American War?

Filipino nationalists led by Emilio Aguinaldo had been fighting Spain for independence and expected freedom after the war. When the treaty made the Philippines an American colony instead, they fought the U.S. in a war lasting roughly 1899-1902.

What territories did the U.S. get from the Treaty of Paris (1898)?

Puerto Rico, Guam, and the Philippines. This matches the CED's essential knowledge (KC-7.3.I.C) that the war led to U.S. acquisition of island territories in the Caribbean and the Pacific.
