Why is it considered that the annexation of Hawaii was imperialist?

Policy to expand the rule or authority of an empire or state to a foreign country, or to acquire and manage colonies and accessories

We usually associate imperialism with war and conquest, but this is not always the case. Through the above definition (of dictionary), the acquisition of the United States of Hawaii can be regarded as imperialism.

America does not conquer or fight Hawaii. Instead, it annexed an independent state who had a provisional government (self-declared) after overthrowing the Kingdom of Hawai'i. The United States is not directly responsible for this rebellion, but it is indirectly participating.

The government of Benjamin Harrison is interested in expanding the power of the United States, and that consul of Honolulu (John L. Stevens) is a supporter of anti-monarchical elements. The army where he landed for public safety during the subversion was only sitting in the camp, but their existence affected them. He is also very happy to recognize the interim government.

As the name of the new government shows, their intent is to be attached by the United States in a short time. If Glover Cleveland's (second) government has not just begun to do so, there is a possibility that the government's policy has been reversed. Furthermore, because the sympathy for the people of Hawaii is widespread in the population of the United States, no transactions are done under any circumstances. At the same time, the United States is also very reluctant to regain the monarchy. So Cleveland tried to recover the kingdom (the apostasy of the resurrected queen was useless at all) and there was nowhere to go.

Finally, the merger took place under the guidance of William McKinley Government. During the Spanish-American war, it was very important to provide motivation that needed Hawaii as a base.

After the war of the Spanish-American, Hawaii saw a new highlight for activities in the Pacific - Hawaii is an important link with the Far East - President McKinley negotiated a new merger treaty, It was arrested by anti-imperialist The Senate could not get the necessary 2/3 votes. Congress then passed Congress' joint resolution to Annex Hawaii, and the resolution simply requires a majority. President McKinley approved the resolution on July 7, Hawaii became the territory of the United States on June 14, 1900.

Dole remained the President of the Independent Republic until the Ohio Governor William McKinley became President by instigating Hawaii's merger through McKinley tariff. On August 12, 1898, Congress used Hawaii as the territory and McKinley appointed Dole as a provisional governor.

Why does the United States keep the overthrow of the sovereign Hawaiian monarchy, why is not it widely known?

After overthrowing, the provisional government of Hawaii became the Republic of Hawaii in 1894 and the Republic of Hawaii was merged into Hawaiian territory by New York resolution in 1898. In 1900, the territory acquired the territory government in the organization bill. Contrary to many attempts to revive the Kingdom of Hawai'i and revive the kingdom, in 1898 it became the territory of the United States even without a native Hawaiian. On March 18, 1959, Hawaii became the United States after a referendum, and at least 93% of the voters voted for the establishment of that country. By that time, most voters were not Hawaiian indigenous peoples. The referendum of 1959 did not choose to be independent from the United States. After Hawaii joined the state, the United Nations deleted Hawaii from the list of non-autonomous territories (a series of territories affected by the colonization process)
