Oahu (Hawaiian: Oʻahu (in Hawaiian pronounced as /oˈʔɐhu/)) is the most populated and third-largest of the Hawaiian Islands.[1] The island of Oahu and the Northwestern Hawaiian Islands constitute the City and County of Honolulu. The state capital, Honolulu, is on Oahu's southeast coast. In 2021, Oahu had a population of 995,638,[2] up from 953,207 in 2010 (approximately 70% of the total 1,455,271 population of the U.S. state of Hawaii,[3] with approximately 81% of those living in or near the Honolulu urban area).
The Island of Oahu in Hawaii is often nicknamed, (or translated as) "The Gathering Place". The translation of "gathering place" was suggested as recently as 1922 by Hawaiian Almanac author Thomas Thrum. Thrum possibly ignored or misplaced the ʻokina because the Hawaiian phrase "ʻo ahu" could be translated as "gathering of objects" (ʻo is a subject marker and ahu means "to gather"). The term Hawaiian: Oʻahu has no other confirmed meaning in Hawaiian.[4] [5]
The island has been inhabited since at least the 3rd century A.D.[6] The 304-year-old Kingdom of Oahu was once ruled by the most ancient aliʻi in the Islands. The first great king of Oahu was Maʻilikūkahi, the lawmaker, who was followed by generations of monarchs. Kualiʻi was the first of the warlike kings and was succeeded by his sons. In 1773, the throne fell upon Kahahana, the son of Elani of Ewa. In 1783, Kahekili II, King of Maui, conquered Oahu, deposed the reigning family, and made his son, Kalanikūpule, king of Oahu, turning Oahu into a puppet state. Kamehameha the Great conquered Kalanikūpule's forces in the Battle of Nuʻuanu. Kamehameha founded the Kingdom of Hawaii with the conquest of Oahu in 1795. Hawaii was not unified until King Kaumualiʻi surrendered the islands of Kauai and Niihau in 1810. Kamehameha III moved his capital from Lahaina, Maui to Honolulu, Oahu in 1845. ʻIolani Palace, built later by other members of the royal family, still stands, and is the only royal palace on American soil.
Oahu was apparently the first of the Hawaiian Islands sighted by the crew of HMS Resolution on January 19, 1778, during Captain James Cook's third Pacific expedition. Escorted by HMS Discovery, the expedition was surprised to find tall islands this far north in the central Pacific. Oahu was not actually visited by Europeans until February 28, 1779, when Captain Charles Clerke aboard HMS Resolution stepped ashore at Waimea Bay. Clerke took command of the ship after James Cook was killed at Kealakekua Bay (island of Hawaiʻi) on February 14, and was leaving the islands for the North Pacific. With the discovery of the Hawaiian Islands came the introduction of disease, mosquitoes, and aggressive animals. Although indirect, simple exposure to these foreign species caused permanent damage to the Native Hawaiian people and environment.
The Imperial Japanese Navy's attack on Pearl Harbor, Oahu on the morning of December 7, 1941, brought the United States into World War II. The surprise attack was aimed at destroying the American will to fight and forcing the US to sue for peace. They attacked the Pacific Fleet of the United States Navy and its defending Army Air Forces and Marine Air Forces. The attack damaged or destroyed 12 American warships, destroyed 188 aircraft, and killed 2,335 American servicemen and 68 civilians (of those, 1,177 were the result of the destruction of the USS Arizona alone).[7] [8]
Oahu then became a tourism and shopping haven. Over five million visitors (mainly from the contiguous United States and Japan) flock there every year.[9]
Oahu is 44miles long and 30miles across. Its shoreline is 227miles long. Including small associated islands such as Ford Island plus those in Kāneʻohe Bay and off the eastern (windward) coast, its area is 596.7sqmi, making it the 20th-largest island in the United States.[10]
The city of Honolulu—the state's capital and largest city is located on the island. As a jurisdictional unit, all of Oahu is in Honolulu County, although Honolulu occupies only part of its southeastern end.
Well-known features of Oahu include Waikiki, Pearl Harbor, Diamond Head, Hawaiian: Hanauma|italic=no|nocat=yes, Kāneʻohe Bay, Kailua Bay, North Shore, and the resort destination Ko Olina.
The island is composed of two separate shield volcanoes: the Waiʻanae and Koʻolau Ranges, with a broad valley or saddle (the central Oahu Plain) between them. The highest point is Kaʻala in the Waiʻanae Range, rising to 4003feet above sea level.[11]
Oahu, along with the rest of the State of Hawaii, relies on tourism as a driving force of the local economy.[12] Popular tourists attractions include beaches such as Ala Moana Beach, Hanauma Bay, Kāneʻohe Bay, Ko Olina Beach Park, Waikiki Beach, among others. Other tourist attractions include Ala Moana Center, Bishop Museum, the Honolulu Museum of Art, ʻIolani Palace, and Kualoa Ranch.
