Territory of Hawaii in the context of "Constitution of Hawaii"

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.

The Hawaiian Kingdom, also known as the Kingdom of Hawaiʻi (Hawaiian: Ke Aupuni Hawaiʻi [kɛ ɐwˈpuni həˈvɐjʔi]), was an archipelagic country from 1795 to 1893, which eventually encompassed all of the inhabited Hawaiian Islands. It was established in 1795 when Kamehameha I, then Aliʻi nui of Hawaii, conquered the islands of Oʻahu, Maui, Molokaʻi, and Lānaʻi, and unified them under one government. In 1810, the Hawaiian Islands were fully unified when the islands of Kauaʻi and Niʻihau voluntarily joined the Hawaiian Kingdom. Two major dynastic families ruled the kingdom, the House of Kamehameha and the House of Kalākaua.

The kingdom subsequently gained diplomatic recognition from European powers and the United States. An influx of European and American explorers, traders, and whalers soon began arriving to the kingdom, introducing diseases such as syphilis, tuberculosis, smallpox, and measles, leading to the rapid decline of the Native Hawaiian population. In 1887, King Kalākaua was forced to accept a new constitution after a coup d'état by the Honolulu Rifles, a volunteer military unit recruited from American settlers. Queen Liliʻuokalani, who succeeded Kalākaua in 1891, tried to abrogate the new constitution. She was subsequently overthrown in a 1893 coup engineered by the Committee of Safety, a group of Hawaiian subjects who were mostly of American descent, and supported by the U.S. military. The Committee of Safety dissolved the kingdom and established the Republic of Hawaii, intending for the U.S. to annex the islands, which it did on July 7, 1898, via the Newlands Resolution. Hawaii became part of the U.S. as the Territory of Hawaii until it became a U.S. state in 1959.

The Pacific War, sometimes called the Asia–Pacific War or the Pacific Theater, was the theater of World War II fought between the Japan and the Allies in East and Southeast Asia, the Pacific and Indian Oceans, and Oceania. It was geographically the largest theater of the war, including the Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the brief Soviet–Japanese War, and included some of the largest naval battles in history. War between Japan and the Republic of China had begun in 1937, with hostilities dating back to Japan's invasion of Manchuria in 1931, but the Pacific War is more widely accepted to have begun in 1941, when the United States and United Kingdom were brought into the war, after being attacked by Japan.

Japan invaded French Indochina in 1940, and extended its control over the entire territory in July 1941. On 7–8 December 1941, Japan attacked the American naval base at Pearl Harbor in Hawaii; the U.S.-held Philippines, Guam, and Wake Island; and the British colonies of Malaya, Singapore, and Hong Kong, followed by a Japanese declaration of war. The Japanese achieved great success over the next 6 months, allying with Thailand and capturing the listed territories (except for Hawaii) in addition to Borneo, New Britain, the Dutch East Indies, Burma, the Solomon and Gilbert Islands, and parts of New Guinea. In May 1942, Japanese and Allied aircraft carriers fought at the Battle of Coral Sea, resulting in the retreat of a Japanese invasion force headed for Port Moresby. In June, Japan invaded the Aleutian Islands, and in the central Pacific was defeated at the Battle of Midway, considered a key turning point in the war. After this point, the Japanese experienced great difficulty replacing their losses in ships and aircraft as the U.S. produced ever increasing numbers of both.

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.

Syngman Rhee (Korean: 이승만; Hanja: 李承晚; pronounced [iː.sɯŋ.man]; 26 March 1875 – 19 July 1965), also known by his art name Unam (우남; 雩南), was a South Korean politician who served as the first president of South Korea from 1948 to 1960. Rhee was also the first and last president of the Provisional Government of the Republic of Korea from 1919 to his impeachment in 1925 and from 1947 to 1948. As president of South Korea, Rhee's administration was characterised by authoritarianism, limited economic development, and in the late 1950s growing political instability and public opposition to his rule.

Born in Hwanghae Province, Joseon, Rhee attended an American Methodist school, where he converted to Christianity. He became a Korean independence activist and was imprisoned for his activities in 1899. After his release in 1904, he moved to the United States, where he received degrees from American universities and met Presidents Theodore Roosevelt and Woodrow Wilson. After a brief 1910–12 return to Korea, he moved to Hawaii in 1913. In 1919, following the Japanese suppression of the March First Movement, Rhee joined the right-leaning Korean Provisional Government in exile in Shanghai. From 1918 to 1924, he served as the first President of the Korean Provisional Government until 1925. He then returned to the United States, where he advocated and fundraised for Korean independence. In 1939, he moved to Washington, DC. In 1945, he was returned to US-controlled Korea by the US military. On 20 July 1948, he was elected the first president of the Republic of Korea by the National Assembly, ushering in the First Republic of Korea.

During World War II, the United States forcibly relocated and incarcerated about 120,000 people of Japanese descent in ten concentration camps operated by the War Relocation Authority (WRA), mostly in the western interior of the country. About two-thirds were U.S. citizens. These actions were initiated by Executive Order 9066, issued by President Franklin D. Roosevelt on February 19, 1942, following Imperial Japan's attack on Pearl Harbor on December 7, 1941. About 127,000 Japanese Americans then lived in the continental U.S., of which about 112,000 lived on the West Coast. About 80,000 were Nisei ('second generation'; American-born Japanese with U.S. citizenship) and Sansei ('third generation', the children of Nisei). The rest were Issei ('first generation') immigrants born in Japan, who were ineligible for citizenship. In Hawaii, where more than 150,000 Japanese Americans comprised more than one-third of the territory's population, only 1,200 to 1,800 were incarcerated.

Internment was intended to mitigate a security risk which Japanese Americans were believed to pose. The scale of the incarceration in proportion to the size of the Japanese American population far surpassed similar measures undertaken against German and Italian Americans who numbered in the millions and of whom some thousands were interned, most of these non-citizens. Following the executive order, the entire West Coast was designated a military exclusion area, and all Japanese Americans living there were taken to assembly centers before being sent to concentration camps in California, Arizona, Wyoming, Colorado, Utah, Idaho, and Arkansas. Similar actions were taken against individuals of Japanese descent in Canada. Internees were prohibited from taking more than they could carry into the camps, and many were forced to sell some or all of their property, including their homes and businesses. At the camps, which were surrounded by barbed wire fences and patrolled by armed guards, internees often lived in overcrowded barracks with minimal furnishing.

The Committee of Safety, formally the Citizen's Committee of Public Safety, was a 13-member group of the Annexation Club. The group was composed of mostly Hawaiian subjects of American descent and American citizens who were members of the Missionary Party, as well as some foreign residents in the Hawaiian Kingdom. The group planned and carried out the overthrow of the Hawaiian Kingdom on January 17, 1893. The goal of this group was to achieve annexation of Hawaii by the United States. The new independent Republic of Hawaii government was thwarted in this goal by the administration of President Grover Cleveland, and it was not until 1898 and under the administration of William McKinley that the United States Congress approved a joint resolution of annexation, creating the U.S. Territory of Hawaii.

The Republic of Hawaii (Hawaiian: Lepupalika o Hawaiʻi, pronounced [lepupəˈlikə o həˈvɐjʔi]) was a short-lived one-party state in Hawaiʻi between July 4, 1894, when the Provisional Government of Hawaii had ended, and August 12, 1898, when it became annexed by the United States as an unincorporated and unorganized territory. In 1893, the Committee of Public Safety overthrew Queen Liliʻuokalani, the monarch of the Kingdom of Hawaiʻi, after she rejected the 1887 Bayonet Constitution. The Committee of Public Safety intended for Hawaii to be annexed by the United States; however, President Grover Cleveland, a Democrat opposed to imperialism, refused. A new constitution was subsequently written while Hawaii was being prepared for annexation.

The leaders of the Republic, such as Sanford B. Dole and Lorrin A. Thurston, were Hawaii-born descendants of American settlers who spoke the Hawaiian language but had strong financial, political, and family ties to the United States. They intended the Republic to become a territory of the United States. Dole was a former member of the Royal Legislature from Koloa, Kauai, and Justice of the Kingdom's Supreme Court, and he appointed Thurston—who had served as Minister of the Interior under King Kalākaua—to lead a lobbying effort in Washington, D.C., to secure Hawaii's annexation by the United States. The issue of overseas imperialism was controversial in the United States due to its colonial origins. Hawaii was annexed under Republican President William McKinley on 12 August 1898, during the Spanish–American War. The Territory of Hawaii was formally established as part of the U.S. on June 14, 1900.
