In March of 1897, William McKinley was inaugurated as President of the United States. McKinley was in favor of annexation, and the change in leadership was soon felt. On June 16, 1897, McKinley and three representatives of the government of the Republic of Hawaii --Lorrin Thurston, Francis Hatch, and William Kinney-- signed a treaty of annexation. President McKinley then submitted the treaty to the U.S. Senate for ratification.
