Oahu in the context of "Hickam Field"

The attack on Pearl Harbor was a surprise military strike by the Empire of Japan on the United States Pacific Fleet at its naval base at Pearl Harbor on Oahu, Hawaii, on December 7, 1941. At the time, the U.S. was a neutral country in World War II. The air raid on Pearl Harbor, which was launched from aircraft carriers, resulted in the U.S. declaring war on Japan the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning.

The attack on Pearl Harbor was preceded by months of negotiations between the U.S. and Japan over the future of the Pacific. Japanese demands included that the U.S. end its sanctions against Japan, cease aiding China in the Second Sino-Japanese War, and allow Japan to access the resources of the Dutch East Indies. Japan sent out its naval attack group on November 26, 1941, just prior to receiving the Hull note, which stated the U.S. desire that Japan withdraw from China and French Indochina. Isoroku Yamamoto, commander of the Japanese Combined Fleet, planned the attack as a pre-emptive strike on the Pacific Fleet, based at Pearl Harbor since 1940 in order to prevent it from interfering with Japan's planned actions in Southeast Asia. Yamamoto hoped that the strike would enable Japan to make quick territorial gains and negotiate peace. In addition to Pearl Harbor, over seven hours Japan launched coordinated attacks on the U.S.-held Philippines, Guam, and Wake Island; and on the British Empire in Malaya, Singapore, and Hong Kong.

An islet (/ˈaɪlət/ EYE-lət) is generally a small island. Definitions vary and are not precise, but some suggest that an islet is a very small, often unnamed, island with little or no vegetation to support human habitation. It may be made of rock, sand and/or hard coral; may be permanent or tidal (i.e. surfaced reef or seamount); and may exist in the sea, lakes, rivers or any other sizeable bodies of water.

Honolulu (/ˌhɒnəˈluːluː/ HON-ə-LOO-loo; Hawaiian: [honoˈlulu]) is the capital and most populous city of the U.S. state of Hawaii, located in the Pacific Ocean. It is the county seat of the consolidated City and County of Honolulu, situated along the southeast coast of the island of Oʻahu. The population of Honolulu was 350,964 at the 2020 census, while the Urban Honolulu metropolitan area has an estimated 1 million residents and is the 56th-largest metropolitan area in the nation.

The area's geography and Honolulu Harbor has long made it desirable as a port, accounting for the city’s growth and importance in the Hawaiian archipelago and the broader Pacific region. In 1845, Honolulu became the capital of the independent Hawaiian Kingdom, a role it maintained as Hawaii became a U.S. territory and at last a U.S. State. The city gained worldwide recognition following the Empire of Japan's attack on nearby Pearl Harbor on December 7, 1941, which prompted the entry of the U.S. into World War II; the harbor remains a major U.S. Navy base, hosting the United States Pacific Fleet, the world's largest naval command.

Molokaʻi or Molokai is the fifth most populated of the eight major islands that make up the Hawaiian Islands archipelago in the middle of the Pacific Ocean. It is 38 by 10 miles (61 by 16 km) at its greatest length and width with a usable land area of 260 sq mi (673.40 km), making it the fifth largest in size of the main Hawaiian Islands and the 27th-largest island in the United States. It lies southeast of Oʻahu across the 25-mile-wide (40 km) Kaʻiwi Channel and north of Lānaʻi, separated from it by the Kalohi Channel.

The island's agrarian economy has been driven primarily by cattle ranching, pineapple production, sugarcane production and small-scale farming. Tourism comprises a small fraction of the island's economy, and much of the infrastructure related to tourism was closed and barricaded in the early 2000s when the primary landowner, Molokai Ranch, ceased operations due to substantial revenue losses. In Kalawao County, on the Kalaupapa Peninsula on the north coast, settlements were established in 1866 for quarantined treatment of persons with leprosy; these operated until 1969. The Kalaupapa National Historical Park now preserves this entire county and area. Several other islands are visible from the shores of Molokaʻi, including Oʻahu from the west shores; Lānaʻi from the south shores, and Maui from the south and east shores.

Maui is the second-largest island in the Hawaiian archipelago, at 727.2 square miles (1,883 km). It is the 17th-largest in the United States. Maui is one of Maui County's four sizable islands, along with Molokaʻi, Lānaʻi, and Kahoʻolawe.

In 2020, Maui had a population of 168,307, the third-highest of the Hawaiian Islands, behind Oʻahu and Hawaiʻi Island. Kahului is the largest census-designated place (CDP) on the island, with a 2020 population of 28,219. It is Maui's commercial and financial hub. Wailuku is the county seat and was the third-largest CDP as of 2010. Other significant populated areas include Kīhei (including Wailea and Makena in the Kihei Town CDP), Lāhainā (including Kāʻanapali and Kapalua in the Lāhainā Town CDP), and Upcountry Maui (including Makawao, Pukalani, Kula, and Ulupalakua), although Lāhainā was mostly destroyed by fire in 2023.

Mōkōlea Rock is an islet in Kailua Bay along the windward coast of Oʻahu in Hawaiʻi and located east of Marine Corps Base Hawaii (MCBH). Like most of the small islets off the coastline of a major island in the Hawaiian Islands, Mōkōlea is a State Bird Sanctuary containing many types of birds. Access to the islet requires a permit, and is only allowed to people involved in protecting the islet's fauna. The islet is more commonly known to local residents as "Birdshit Island", "Birdshit", or simply "Bird" because its black lava rock surface is heavily coated with bird droppings.

There is no vegetation on the islet, which is actually three connected outcroppings, the highest of which is no more than 25 feet (7.6 m) above mean sea level. All three consist of barren, jagged lava. Mokolea is part of the windward rim of the Kawainui volcanic caldera. About 300 feet (91 m) from this outcropping on the side facing Kailua Beach a shelf juts up from deep water to a depth of 25 to 30 feet (7.6 to 9.1 m). The shelf is a moderately interesting spot for scuba diving, although much of the time the area is rough, and anchoring a boat is difficult.

Marine Corps Base Hawaii (MCBH), formerly Marine Corps Air Station Kaneohe Bay and originally Naval Air Station Kaneohe Bay, is a U.S. Marine Corps facility and air station located on the Mokapu Peninsula of windward O'ahu in the City & County of Honolulu. Marine Corps Base Hawaii is home to Marines, Sailors, their family members, and civilian employees. The United States Marine Corps operates a 7,800-foot (2,400 m) runway at the base.

MCBH is home for the 3rd Marine Littoral Regiment, Marine Aircraft Group 24, Combat Logistics Company 33 (CLC-33), 3rd Radio Battalion, and the Navy's Patrol and Reconnaissance Wing 2.

Liliʻuokalani (Hawaiian pronunciation: [liˌliʔuokəˈlɐni]; Lydia Liliʻu Loloku Walania Kamakaʻeha; September 2, 1838 – November 11, 1917) was the only queen regnant and the last sovereign monarch of the Hawaiian Kingdom, ruling from January 29, 1891, until the overthrow of the Hawaiian Kingdom on January 17, 1893, in a coup that was led by the Committee of Safety, composed of seven foreign residents (five Americans, one Scotsman, and one German) and six Hawaiian Kingdom subjects of American descent in Honolulu. The composer of "Aloha ʻOe" and numerous other works, she wrote her autobiography Hawaiʻi's Story by Hawaiʻi's Queen (1898) during her imprisonment following the overthrow.

Liliʻuokalani was born in 1838 in Honolulu, on the island of Oʻahu. While her natural parents were Analea Keohokālole and Caesar Kapaʻakea, she was hānai (informally adopted) at birth by Abner Pākī and Laura Kōnia and raised with their daughter Bernice Pauahi Bishop. Baptized as a Christian and educated at the Royal School, she and her siblings and cousins were proclaimed eligible for the throne by King Kamehameha III. She was married to American-born John Owen Dominis, who later became the Governor of Oʻahu. The couple had no biological children but adopted several. After the accession of her brother David Kalākaua to the throne in 1874, she and her siblings were given Western-style titles of Prince and Princess. In 1877, after her younger brother Leleiohoku II's death, she was proclaimed as heir apparent to the throne. During the Golden Jubilee of Queen Victoria, she represented her brother as an official envoy to the United Kingdom.
