The islands which now form the Republic of Kiribati have been inhabited for at least seven hundred years, and possibly much longer. The initial Austronesian peoples’ population, which remains the overwhelming majority today, was visited by Polynesian and Melanesian invaders before the first European sailors visited the islands in the 17th century. For much of the subsequent period, the main island chain, the Gilbert Islands, was ruled as part of the British Empire. The country gained its independence in 1979 and has since been known as Kiribati.

For several millennia, the islands were inhabited by Austronesian peoples who had arrived from the Solomon Islands or Vanuatu. The I-Kiribati or Gilbertese people settled what would become known as the Gilbert Islands (named for British captain Thomas Gilbert by von Krusenstern in 1820) some time in between 3000 BC^[1][2] and 1300 AD.^[3] Subsequent invasions by Samoans and Tongans introduced Polynesian elements to the existing Micronesian culture, and invasions by Fijians introduced Melanesian elements. Extensive intermarriage produced a population reasonably homogeneous in appearance, language and traditions.

In 1606 Pedro Fernandes de Queirós sighted Butaritari and Makin, which he named the Buen Viaje ('good trip' in Spanish) Islands.^[4]

Captain John Byron passed through the islands in 1764 during his circumnavigation of the globe as captain of HMS Dolphin.^[5]

In 1788, Captain Thomas Gilbert in Charlotte and Captain John Marshall in Scarborough. Messrs. Gilbert and Marshall passed close to Abemama, Kuria, Aranuka, Tarawa, Abaiang, Butaritari, and Makin without attempting to land on shore.^[6]

In 1820, the islands were named the îles Gilbert (in French, Gilbert Islands) by Adam Johann von Krusenstern, a Russian admiral of the Czar after the British Captain Thomas Gilbert, who crossed the archipelago in 1788. In 1824, French captain Louis-Isidore Duperrey was the first to map the whole Gilbert Islands archipelago. He commanded La Coquille on its circumnavigation of the earth (1822–1825).^[7]

Two ships of the United States Exploring Expedition, USS Peacock (1828) and USS Flying Fish (1838), under the command of Captain Hudson, surveyed the Gilbert Islands of Tabiteuea, Nonouti, Aranuka, Maiana, Abemama, Kuria, Tarawa, Marakei, Butaritari, and Makin^[8] (then called the Kingsmill Islands or Kingsmill Group in English). While in the Gilberts, they devoted considerable time to mapping and charting reefs and anchorages.^[9] Alfred Thomas Agate made drawings of men of Butaritari and Makin.^[10]

At one time, a subset of the northern Gilbert islands was known as Scarborough Islands and a subset of the southern Gilberts as the Kingsmill Group; in some 19th century texts, this last name of Kingsmills was applied to the entire Gilberts group.^[11]

Missionaries began to be active in the Gilbert Islands in the 1850s. Dr Hiram Bingham II of the American Board of Commissioners for Foreign Missions (ABCFM) arrived on Abaiang in 1857. The protestant missionaries of the London Missionary Society (LMS) were active in the southern Gilberts. On 15 October 1870, Rev. Samuel James Whitmee of the LMS arrived at Arorae, and later that month he visited Tamana, Onotoa and Beru.^[12] In August 1872, George Pratt of the LMS visited the islands.^[13] The Roman Catholic faith was introduced on Nonouti around 1880 by 2 Gilbert islanders, Betero and Tiroi, who had become christians in Tahiti. Father Joseph Leray, Father Edward Bontemps and Brother Conrad Weber, Roman Catholic Missionaries of the Sacred Heart arrived on Nonouti in 1888.^[14]

Robert Louis Stevenson, Fanny Vandegrift Stevenson, and her son Lloyd Osbourne, stayed for 2 months on Abemama in 1889, which was described by Stevenson in his account of the 1889 voyage of the Equator published as In the South Seas^[15][16] At the time of their visit, the High Chief was Tembinok', the last of the dozens of expansionist chiefs of Gilbert Islands of this period, despite Abemama historically conforming to the traditional southern islands' governance of their respective unimwaane. Tembinok' was immortalised in Stevenson's book as "the last tyrant",^[17] with Stevenson delved into the high chief's character and method of rule during his stay on Abemama; Tembinok' controlled the access of european traders to the atolls under his control and jealously guarded his revenue and his prerogatives as monarch.^[16]

Robert Louis Stevenson, Fanny Vandegrift Stevenson and Lloyd Osbourne also visited Butaritari from 14 July 1889 to early August.^[18] At this time Nakaeia was the ruler of Butaritari and Makin atolls, his father being Tebureimoa and his grandfather being Tetimararoa. Nakaeia was described by Stevenson as “a fellow of huge physical strength, masterful, violent … Alone in his islands it was he who dealt and profited; he was the planter and the merchant” with Stevenson describing his subjects toiling in servitude and fear.^[16]

Nakaeia allowed two San Francisco trading firms to operate, Messrs. Crawford and Messrs. Wightman Brothers, with up to 12 Europeans resident on islands of the atolls. The presence of the Europeans, and the alcohol they traded to the islanders, resulted in periodic alcoholic binges that only ended with Nakaeia making tapu (forbidding) the sale of alcohol. During the 15 or so days that Stevenson spent on Butaritari the islanders were engaged in a drunken spree that threatened the safety of Stevenson and his family. Stevenson adopted the strategy of describing himself as the son of Queen Victoria so as to ensure that he would be treated as a person who should not be threatened or harmed.^[16]

Robert Louis Stevenson, Fanny Vandegrift Stevenson and Lloyd Osbourne returned to Abemama in July 1890 during their cruise on the trading steamer, Janet Nicoll.^[19]

The first traders resident in the Gilberts were Richard Randell and George Durant who arrived in 1846.^[20] Durant moved on to Makin, while Randell remained on Butaritari.^[21] The earliest trading companies on Butaritari were the Hamburg-based Handels-und Plantagen-Gesellschaft der Südsee-Inseln zu Hamburg (DHPG) with Pacific headquarters in Samoa, and On Chong (Chinese traders with Australian connections via the goldfields). The Japanese trading company Nanyo Boeki Kabushiki Kaisha established operations on Butaritari. Two San Francisco trading firms, Messrs. Crawford and Messrs. Wightman Brothers, were operating on Butaritari in 1889.^[22]

W. R. Carpenter & Co. (Solomon Islands) Ltd was established in 1922.^[23][24][25] Through the 1920s On Chong experienced gradual decline in its operations as the result of low copra prices. Eventually On Chong was taken over by W. R. Carpenter & Co. These traders helped Butaritari became the commercial and trading capital of the Gilbert Islands until Burns Philp, the trading company based in Sydney, Australia, moved to Tarawa, following the seat of political power.

Whalers, blackbirders, and merchant vessels arrived in great numbers in the 19th century, and the resulting upheaval fomented local tribal conflicts and introduced damaging European diseases. In an effort to restore a measure of order, the Gilbert Islands were declared as the British Protectorate by Captain Edward Davis of HMS Royalist (1883) on 27 May 1892.^[26][27] The neighboring Ellice Islands (now Tuvalu) were declared a British Protectorate later in 1892.^[28] The Gilbert and Ellice Islands Protectorate was administered as part of the British Western Pacific Territories (BWPT).^[28]

The BWPT were administered by a High Commissioner resident in Fiji until 1952, then in Honiara.

A Resident Commissioner, Charles Swayne, was appointed in 1893 following the protectorate on the Gilbert group and on the Ellice group becoming formal and effective in 1892. The protectorate's headquarters was established on Tarawa in 1896, where Resident Commissioner William Telfer Campbell presided from 1896 until 1908. The headquarters were then moved to Ocean Island (now Banaba), and continued upon the transition to a Crown Colony. This move in headquarters arose from the operations of the Pacific Phosphate Company resulting in good shipping connections to Ocean Island, and in any case the role of the British colonial authorities emphasised the procurement of labour for the mining and shipping of phosphate and keeping order among the workers.^[29][30]

Ocean Island (now Banaba) was included in the protectorate in 1900 and then in the colony in 1916.^[29][30] In the same year, Fanning Island and Washington Island were included in it together with the islands of the Union Islands (now Tokelau).^[31]

In 1916, the administration of the BWTP changed as the islands became a Crown Colony on 12 January 1916. But the new colony remained under the jurisdiction of BWTP until 1971.^[32]

The islands became a Crown Colony on 12 January 1916 by the Gilbert and Ellice Islands Order in Council, 1915.^[33] Christmas Island was included in the colony in 1919 although it was contested by the U.S. under the Guano Islands Act of 1856.^[34] The Union Islands were unofficially transferred to New Zealand administration in 1926 and officially in 1948. The Phoenix Islands were added in 1937 and the five islands of the Central and Southern Line Islands were added in 1972.^[31]

The Gilbert and Ellice Islands Colony continued to be administered by a Resident Commissioner. One very famous colonial officer in the colony was Sir Arthur Grimble (1888–1956), at first as a cadet officer in 1914, under Edward Carlyon Eliot who was Resident Commissioner of the BWPT then the colony from 1913 to 1920. This period is described in Eliot's book "Broken Atoms" (autobiographical reminiscences) (Pub. G. Bles, London, 1938) and in Sir Arthur Grimble's "A Pattern of Islands" (Pub. John Murray, London, 1952). Arthur Grimble became the Resident Commissioner of the colony in 1926. In 1930 Grimble, issued revised laws, Regulations for the good Order and Cleanliness of the Gilbert and Ellice Islands, which replaced laws created during the BWPT.

Ocean Island remained the headquarters of the colony until the British evacuation in 1942 because of the Japanese occupation of the Gilbert Islands. After World War II, the colony headquarters was re-established on Tarawa, first on Betio islet (then occupied by American forces following the Battle for Tarawa) and subsequently on Bairiki.^[31][35][36]

Japan seized part of the islands during World War II to form part of their island defenses. On 20 November 1943, Allied forces threw themselves against Japanese positions at Tarawa and Makin in the Gilberts, resulting in some of the bloodiest fighting of the Pacific campaign. The Battle of Tarawa and the Battle of Makin (in fact Butaritari) were a major turning point in the war for the Allies, which battles were the implementation of "Operation Galvanic".^[37]

The formation of the United Nations Organisation after World War II resulted in the United Nations Special Committee on Decolonization committing to a process of decolonisation; as a consequence the British colonies in the Pacific started on a path to self-determination.

As a consequence of the 1974 Ellice Islands self-determination referendum,^[38] separation occurred in two stages. The Tuvaluan Order 1975 made by the Privy Council, which took effect on 1 October 1975, recognised Tuvalu as a separate British dependency with its own government. The second stage occurred on 1 January 1976 when separate administrations were created out of the civil service of the Gilbert and Ellice Islands Colony.^[39]

The Gilberts obtained internal self-government in 1977 and held general elections in February 1978 which saw Ieremia Tabai elected Chief Minister at only age 27. Kiribati attained independence as a republic within the Commonwealth of Nations on 12 July 1979 by the Kiribati Independence Order 1979 made by the Privy Council of the United Kingdom.

Although the indigenous Gilbertese language name for the Gilbert Islands proper is Tungaru, the new state chose the name "Kiribati," the Gilbertese rendition of "Gilberts," as an equivalent of the former colony to acknowledge the inclusion of islands which were never considered part of the Gilberts chain.^[40] The United States gave up its claims to 14 islands of the Line and Phoenix chains (previously asserted under the Guano Islands Act) in the 1979 Treaty of Tarawa.^[41]

Following independence, the Kiribati head of state was Ieremia Tabai. At 29-years-old, Tabai served three terms as Beretitenti (President), from 1979 to 1991. Tabai was the youngest head of state in the Commonwealth of Nations.

In 1994, Teburoro Tito was elected Beretitenti. He was reelected in 1998 and 2002 but was ousted in a no-confidence vote in March 2003, and having served the maximum three terms, he is barred by the constitution from running for another term. Tito's temporary replacement was Tion Otang, the Council of State chairman. In 2003, a new presidential election was held, in which two brothers, Anote and Harry Tong, were the two main candidates (a third candidate, Banuera Berina, won just 9.1% of the vote.

Anote Tong, a London School of Economics graduate, won on 4 July 2003, and was sworn in as President soon afterward. He was re-elected in 2007 and in 2012 for a third term. ^[42]

In March 2016, Taneti Maamau was elected as the new President of Kiribati. He was the fifth president since the country became independent in 1979.^[43] In June 2020, President Maamau won re-election for second four-year term. President Maamau was considered pro-China and he supported closer ties with Beijing.^[44]

An emotional issue has been the protracted bid by the residents of Banaba to secede and have their island placed under the protection of Fiji. Because Banaba was devastated by phosphate mining,^[29][30] the vast majority of Banabans was deported to the island of Rabi in the Fiji Islands in the 1940s where they now number some 5,000 and enjoy full Fijian citizenship. The Kiribati government has responded by including several special provisions in the Constitution, such as the designation of a Banaban seat in the legislature and the return of land previously acquired by the government for phosphate mining. Only around 300 people remain on Banaba. Despite being part of Kiribati, Banaba's municipal administration is by the Rabi Council of Leaders and Elders, which is based on Rabi Island, in Fiji. In 2006, Teitirake Corrie, the Rabi Island Council's representative to the Parliament of Kiribati, called for Banaba to secede from Kiribati and join Fiji.

When the COVID-19 pandemic began in early 2020, Kiribati closed off its borders, to the extent that citizens living abroad were prevented from returning. The nation remained free of the infection and in late 2021, as the case rate seemed to be declining in many countries, the government considered relaxing restrictions. By that time, 33 percent of the nation's residents had been fully vaccinated against infection. In January 2022, a group of Kiribati citizens who had been living and travelling abroad as missionaries for the Church of Jesus Christ of Latter-day Saints when the pandemic began returned to Kiribati on a chartered plane. Despite negative tests for the coronavirus that causes COVID-19 before and after arrival, and a quarantine period, 36 of the 54 passengers tested positive soon after their arrival. Within a few days, the viral infection had spread to more than 180 members of the community.^[45]
