Kingman Reef territory claimed by United States of America
Kingman Reef  is a largely submerged, uninhabited, triangle-shaped reef, geologically an atoll, 9.0 nmi (20 km) east-west and 4.5 nmi (8 km) north-south, in the North Pacific Ocean, roughly halfway between the Hawaiian Islands and American Samoa. It has an area of 3 hectares (0.03 km2; 7.4 acres) and is one of the unincorporated territories of the United States in Oceania. The reef is administered by the United States Fish and Wildlife Service as the Kingman Reef National Wildlife Refuge.History
Kingman Reef was discovered on June 14, 1798, by the American captain Edmund Fanning, of the ship Betsey. It was first described by Captain W. E. Kingman (whose name the island bears) of the ship Shooting Star on November 29, 1853. It was claimed in 1859 by the United States Guano Company, under the name "Dangers Rock," along with a number of other islands. The claim was made under the U.S. Guano Islands Act of 1856, although there is no evidence that guano existed or was ever mined on Kingman Reef. The British steamship Tarta struck the reef in June 1874, and it was later surveyed by HMS Penguin (1876) in 1897, establishing that Kingman Reef was the same hazard previously charted as Caldew Reef and Maria Shoal, among other names.On May 10, 1922, Lorrin A. Thurston became the first person to raise the American flag on the atoll and read a proclamation of annexation. The Palmyra Copra Co. intended to use Kingman as a fishing base, as demand for copra had declined after World War I and Palmyra Island lacked a suitable anchorage. Thurston formally claimed Kingman for the United States by reading the following declaration while standing on its shore:
