The Annexation of Hawaii (1898) was the formal U.S. takeover of the Hawaiian Islands by joint resolution of Congress during the Spanish-American War, completing a process that began when American sugar planters overthrew Queen Liliuokalani in 1893 and marking America's imperial turn in the Pacific.
The Annexation of Hawaii is the moment the United States formally absorbed the Hawaiian Islands as a U.S. territory in July 1898. The short version of the backstory: American sugar planters and businessmen had dominated Hawaii's economy for decades, and in 1893 they overthrew Queen Liliuokalani with help from U.S. Marines. They immediately asked Washington to annex the islands. President Cleveland refused, calling the overthrow dishonorable. The request sat on ice until the Spanish-American War broke out in 1898.
The war changed the math. Once the U.S. was fighting Spain in the Philippines, Hawaii suddenly looked less like a sugar colony and more like an essential naval refueling stop in the middle of the Pacific. President McKinley pushed annexation through Congress as a joint resolution (the Newlands Resolution), which only needed a simple majority instead of the two-thirds Senate vote a treaty requires. Hawaii became a territory, Pearl Harbor became a permanent naval base, and the U.S. locked in a Pacific empire that stretched from California to Manila.
This term lives in Topic 7.3, The Spanish-American War, in Unit 7 (1890-1945). It directly supports learning objective APUSH 7.3.A (explain the effects of the Spanish-American War) and essential knowledge KC-7.3.I.C, which says the war led to U.S. acquisition of island territories in the Pacific and increased involvement in Asia. Hawaii is your cleanest example of that essential knowledge in action.
It also matters for the America in the World theme. Hawaii is the hinge between old-school continental expansion (Manifest Destiny) and the new overseas imperialism of the 1890s. If an essay prompt asks whether American expansion in this era was a continuity or a change, Hawaii is the evidence that works both ways, which is exactly what strong DBQ arguments are built on. Head to the Topic 7.3 study guide for the full Spanish-American War picture.

Spanish-American War (Unit 7)
The war is what turned annexation from a stalled proposal into a done deal. Fighting Spain in the Philippines made Hawaii's location strategically priceless as a coaling and supply station, so Congress annexed it mid-war in 1898.
Cleveland's Rejection (Unit 7)
Cleveland refused the first annexation request in 1893 because the overthrow of Queen Liliuokalani was illegitimate. The five-year gap between overthrow and annexation is itself useful evidence that imperialism was contested, not inevitable.
Manifest Destiny (Units 5-6)
Hawaii lets you argue continuity across periods. The same expansionist logic that justified taking the continent in the 1840s got repackaged for overseas islands in the 1890s, just with the ocean replacing the frontier.
Boxer Rebellion (Unit 7)
Annexing Hawaii gave the U.S. the Pacific stepping stones it needed to project power into Asia, which is why America could send troops to China in 1900 and push the Open Door Policy. Hawaii is the infrastructure behind U.S. involvement in Asia.
Hawaii usually shows up as an effect of the Spanish-American War or as evidence of America's imperial turn. Multiple-choice stems often pair it with a political cartoon or a McKinley-era document and ask what strategic calculation drove Pacific expansion. The expected answer is naval power and access to Asian markets, not just sugar.
On FRQs, Hawaii is prime DBQ evidence. The 2018 DBQ asked you to evaluate the causes of America's expanding world role from 1865 to 1910, and Hawaii fits multiple causal threads at once (economic interests, naval strategy, imperialist ideology). The move that earns complexity points is showing the 1893-1898 gap: planters wanted annexation for economic reasons, but it took wartime strategic needs to actually make it happen.
Both happened in 1898 and both gave the U.S. Pacific territory, but they got there differently. The Philippines came from Spain through the Treaty of Paris as a spoil of war, and the U.S. then fought a brutal war to suppress Emilio Aguinaldo's nationalist movement. Hawaii was never Spanish territory at all. It was annexed by a separate joint resolution of Congress after American planters had already overthrown the monarchy in 1893. If a question asks what the U.S. won FROM Spain, Hawaii is the wrong answer.
Hawaii was formally annexed in July 1898 by a joint resolution of Congress during the Spanish-American War, five years after American sugar planters overthrew Queen Liliuokalani.
President Cleveland rejected annexation in 1893 because the overthrow was illegitimate; McKinley revived it in 1898 because the war made Hawaii's location strategically essential.
Hawaii was not taken from Spain, so it is separate from the Treaty of Paris acquisitions like the Philippines, Puerto Rico, and Guam.
Annexation gave the U.S. Pearl Harbor and a permanent naval foothold in the Pacific, enabling deeper involvement in Asia (KC-7.3.I.C).
For essays, Hawaii works as evidence of both continuity (Manifest Destiny extended overseas) and change (a new overseas empire), which makes it strong DBQ material on expansion from 1865 to 1910.
It was the formal U.S. takeover of the Hawaiian Islands in July 1898, passed as a joint resolution of Congress during the Spanish-American War. It followed the 1893 overthrow of Queen Liliuokalani by American sugar planters and marked a major step in U.S. Pacific imperialism.
No. Hawaii was an independent kingdom, then a planter-run republic, never a Spanish colony. The war prompted annexation by making Hawaii strategically valuable, but Hawaii was annexed by a separate act of Congress, not through the Treaty of Paris like the Philippines, Puerto Rico, and Guam.
Cleveland rejected annexation in 1893 because the overthrow of Queen Liliuokalani relied on U.S. Marines and lacked Hawaiian consent. By 1898, McKinley faced a war in the Pacific, and Hawaii's value as a naval refueling station outweighed those objections.
Hawaii was annexed by congressional joint resolution and was never Spanish territory; the Philippines was ceded by Spain in the 1898 Treaty of Paris. The Philippines also triggered a war against Emilio Aguinaldo's nationalist movement, while Hawaii's resistance had already been crushed with the 1893 overthrow.
It is the go-to evidence for KC-7.3.I.C, the essential knowledge that the Spanish-American War led to Pacific territorial acquisition and increased U.S. involvement in Asia. It appeared as usable evidence on the 2018 DBQ about the causes of America's expanding world role from 1865 to 1910.
