Final answer:
The United States took several actions to annex Hawaii, including establishing a provisional government and submitting a treaty for annexation to the United States. The annexation of Hawaii was supported by President McKinley during the Spanish-American War.
Step-by-step explanation:
The United States took several actions to annex Hawaii. In 1893, a group of primarily American conspirators forced Queen Liliuokalani to abdicate, establishing a provisional government. They then submitted a treaty for annexation to the United States. Although President Grover Cleveland initially refused to seek annexation, in 1898, during the Spanish-American War, President William McKinley supported Hawaii's annexation. The annexation resolution was passed, and Hawaii became a US territory in 1900.
