 Answer :

when america annexed Hawaii in 1898, the U.S. territory extended into the Pacific, as result an highlighted economic integration and a rise  as a Pacific power.During the 1830s, Britain and France forced Hawaii to accept treaties giving them economic privileges.Therefore in 1842, Secretary of State Daniel Webster sent a letter to Hawaiian agents in Washington affirming U.S. interests in Hawaii and opposing annexation by any other nation and in 1849, they concluded a treaty of friendship that served as the basis of official relations between the parties.

As a economic result, fertile ground for american protestant missionaries, and a new source of sugar cane production, Hawaii's economy became increasingly integrated with the United States. An 1875 trade reciprocity treaty further linked the two countries and u.s. sugar plantation owners from the United States came to dominate the economy and politics of the islands

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.
