The legal status of Hawaii—as opposed to its political status—is a settled legal matter but there has been scholarly and legal debate. While Hawaii is internationally recognized as a state of the United States of America while also being broadly accepted as such in mainstream understanding, there have been essays written denying the legality of this status. The argument is that Hawaii is an independent nation under military occupation. The legality of control of Hawaii by the United States has also been raised in the losing side in cases in the U.S. Supreme Court, and in U.S. District Court.
The islands that we know of today as Hawaii were settled by Polynesian explorers some time around 350 AD. The indigenous inhabitants are referred to as kānaka maoli. After 1778, and the arrival of James Cook, populations levels changed drastically and eventually the islands would be unified in 1795 under the leadership of Kamehameha I. Within one hundred years of the founding of the kingdom, American political and religious influence would erode the powers of the indigenous monarchs and eventually overthrow the kingdom on January 17, 1893.
A provisional government was established which favored annexation. U.S. President Grover Cleveland rejected the provisional government for the illegal overthrow of a sovereign nation and demanded the restoration of Queen Liliʻuokalani to her rightful place as ruler of the Kingdom of Hawaii. The new government refused and the Republic of Hawaii was declared instead. Cleveland sent Georgia Congressman James Henderson Blount to investigate the matter. Following his investigation, Blount issued a 1342-page report on July 17, 1893, which called the coup an "act of war" against a friendly and independent nation, and recommended that appropriate measures be taken by the U.S. to restore the Hawaiian Kingdom. The Cleveland Administration, and particularly Secretary of State Gresham, recommended the fair yet forcible removal of the usurpers from power. They were advised, however, that this would require a Declaration of War. It was doubtful that Congress would pass such a measure against its own citizens.
