Geological research in the early 21st century indicates that Necker Island is about 10 million years old. While it rises only about 84 meters (277 ft) above
sea level now, it reached in height earlier in its history and at one time was comparable in size to modern
Oahu.
Hawaiians appear to have started visiting Necker Island a few hundred years after they settled the main Hawaiian Islands. Archaeologists believe that the island's poor soil for farming and its small size and relative lack of rainfall made it uninhabitable, and that the Hawaiians visited from Nīhoa and other nearby islands to worship at religious sites without establishing any permanent settlements. In 1785, the French explorer
Jean-François de La Pérouse left
France to
circumnavigate the world on a mission of exploration for the
French Academy of Sciences aboard the ships
Astrolabe (under command of
Fleuriot de Langle) and
Boussole. The expedition had just discovered the
French Frigate Shoals (
Basse des Frégates Françaises) and La Pérouse's namesake rock,
La Perouse Pinnacle, when on November 4, 1786, La Pérouse and his crews became the first Europeans to visit Necker Island. as part of the
British Empire telegraph network known informally as the
All Red Line. The Kingdom of Hawaii was overthrown in 1893 and replaced by the
Provisional Government of Hawaii, and when the British
corvette arrived at
Honolulu in 1894, the provisional government's president,
Sanford B. Dole, became concerned that the United Kingdom was about to establish a claim to Necker Island. Wishing to curry favor with the
United States rather than the United Kingdom, Dole immediately dispatched an expedition under Captain
James A. King to Necker to
annex the island. On May 27, 1894, a landing party of 12 men led by King went ashore on Necker for four hours, raised the
flag of Hawaii on what became known as Annexation Hill, and read an annexation proclamation. The move brought international disputes over claims to the island to an end and the island was included in the
Republic of Hawaii when it was founded on July 4, 1894, although the
British government continued to attempt to negotiate with the Hawaiian government over use of Necker Island and on September 24, 1894,
Champion landed a British party on the island. On June 15, 2006, the United States established the
Papahānaumokuākea Marine National Monument, with Necker Island within its boundaries. ==Access==
