Why did the us want to annex hawaii

Dole declared Hawaii an independent republic. Spurred by the nationalism aroused by the Spanish-American War, the United States annexed Hawaii in 1898 at the urging of President William McKinley. Hawaii was made a territory in 1900, and Dole became its first governor.

Because the US wanted to expand its economy, and foreign relations. Also,  Hawaii was a really good strategical point on the map, which helps from a war stand point.
