History

According to Tongan mythology, the demigod Maui drew up a group of islands from the ocean, first appearing Tongatapu, the Ha'apai Islands and Vava'u, integrating into what became modern-day Tonga.

An Austronesian -speaking group linked to what archaeologists call the Lapita culture covered from Island Melanesia to Samoa, and then on to inhabit Tonga sometime between 1500 and 1000 BC. Scholars still debate exactly when Tonga was first settled, but thorium dating confirms that settlers had arrived in the earliest known inhabited town, Nukuleka, by 888 BC, ± 8 years. Tonga's precontact history was shared via oral history, which was passed down from generation to generation.

By the 12th century, Tongans and the Tongan monarch, the Tuʻi Tonga, had acquired a reputation across the central Pacific – from Niue, Samoa, Rotuma, Wallis and Futuna, New Caledonia to Tikopia, leading some historians to speak of a Tuʻi Tonga Empire having existed during that period. Civil wars are known to have occurred in Tonga in the 15th and 17th centuries.

The Tongan people first encountered Europeans in 1616, when the Dutch vessel Eendracht, captained by Willem Schouten, made a short visit to the islands for the purpose of engaging in trade. Later, other Dutch explorers arrived, including Jacob Le Maire (who visited the northern island of Niuatoputapu); and Abel Tasman (who visited Tongatapu and Haʻapai) in 1643. Later noteworthy European visitors included James Cook, of the British Royal Navy, in 1773, 1774, and 1777; Spanish Navy explorers Francisco Mourelle de la Rúa in 1781; Alessandro Malaspina in 1793; the first London missionaries in 1797; and a Wesleyan Methodist minister, Reverend Walter Lawry, in 1822.

Whaling vessels were among the earliest regular Western visitors. The first of these on record is the Ann and Hope, which was reported to have been seen among the islands of Tonga in June 1799. The last known whaling visitor was the Albatross in 1899. That ship arrived in Tonga seeking a resupply of water, food, and wood. The islands most regularly visited by Westerners were Ata, 'Eua, Ha'apai, Tongatapu and Vava'u. Sometimes, Tongan men were recruited to serve as crewmen on these vessels.The United States Exploring Expedition visited Tonga in 1840.

In 1845, an ambitious young Tongan warrior, strategist, and orator named Tāufaʻāhau united Tonga into a kingdom. He held the chiefly title of Tuʻi Kanokupolu, but had been baptised by Methodist missionaries with the name Siaosi ("George") in 1831. In 1875, with the help of missionary Shirley Waldemar Baker, he declared Tonga a constitutional monarchy, formally adopted the Western royal style, emancipated the "serfs", enshrined a code of law, land tenure, and freedom of the press, and limited the power of the chiefs.

Tonga became a protected state under a Treaty of Friendship with Britain on 18 May 1900, when European settlers and rival Tongan chiefs unsuccessfully tried to oust the man who had succeeded Tāufaʻāhau as king. The treaty posted no higher permanent representative on Tonga than a British consul (1901–1970). Under the protection of Britain, Tonga maintained its sovereignty and remained the only Pacific nation to retain its monarchical government. The Tongan monarchy follows an uninterrupted succession of hereditary rulers from one family.

The 1918 flu pandemic, brought to Tonga by a ship from New Zealand, killed 1,800 Tongans, a mortality rate of about 8%.

The Treaty of Friendship and Tonga's protection status ended in 1970 under arrangements that had been established by Tonga's Queen Salote Tupou III before her death in 1965. Owing to its British ties, Tonga joined the Commonwealth in 1970 (atypically as a country that had its own monarch, rather than having the United Kingdom's monarch, along with Malaysia, Lesotho, and Eswatini). Tonga became a member of the United Nations in September 1999. While exposed to colonial pressures, Tonga has always governed itself, which makes it unique in the Pacific.

In January 2022, the Hunga Tonga–Hunga Haʻapai volcano, 65 km (40 mi) north of the main island of Tongatapu, erupted, causing a tsunami which inundated parts of the archipelago, including the capital Nuku ʻ alofa. The eruption affected the kingdom heavily, cutting off most communications and killing four people in Tonga, including a British national who ran an animal shelter and died trying to save her dogs. In Peru, two women drowned due to abnormal tsunami waves. It took around five weeks to repair a submarine fiber optic cable used in the Tonga Cable System for internet and telephone connectivity.
