Hawaii becomes a United States territory.

The Territory of Hawaii or Hawaii Territory was an organized incorporated territory of the United States that existed from April 30, 1900, until August 21, 1959, when most of its territory, excluding Palmyra Island, was admitted to the United States as the 50th US state, the State of Hawaii. The Hawaii Admission Act specified that the State of Hawaii would not include Palmyra Island, the Midway Islands, Kingman Reef, and Johnston Atoll, which includes Johnston Island and Sand Island.

In the United States, a territory is any extent of region under the sovereign jurisdiction of the federal government of the United States, including all waters. The United States asserts sovereign rights for exploring, exploiting, conserving, and managing its territory. This extent of territory is all the area belonging to, and under the dominion of, the United States federal government for administrative and other purposes. The United States total territory includes a subset of political divisions.
