The Pitcairn Islands ( PIT-kairn; Pitkern: Pitkern Ailen), officially Pitcairn, Henderson, Ducie and Oeno Islands, are a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The four islands—Pitcairn, Henderson, Ducie and Oeno—are scattered across several hundred kilometres of ocean and have a combined land area of about 47 square kilometres (18 square miles). Henderson Island accounts for 86% of the land area, but only Pitcairn Island is inhabited. The inhabited islands nearest to the Pitcairn Islands are Mangareva (of French Polynesia), 688 km (428 miles) to the west, as well as Easter Island, 1,929 km (1199 miles) to the east.
The Pitcairn Islanders are descended primarily from nine British HMS Bounty mutineers and twelve Tahitian women. In 2023, the territory had a permanent population of 35, making it the smallest territory in the world by number of permanent residents. Owing to the island's extreme isolation and small population, incidents of widespread sexual abuse went undetected until 1999, culminating in a high-profile sexual assault trial in 2004.
Various forms of evidence show the earliest settlers of the Pitcairn Islands were Polynesians who occupied Pitcairn and Henderson for several centuries until the islands were abandoned: Henderson most likely before the 16th century and Pitcairn in the 17th or early 18th century. The islands were uninhabited when they were rediscovered by Europeans.
Portuguese sailor Pedro Fernandes de Queirós came upon Ducie and Henderson Islands while sailing for the Spanish Crown, arriving on 26 January 1606. He named them La Encarnación ("The Incarnation") and San Juan Bautista ("Saint John the Baptist"), respectively. However, some sources express doubt about exactly which of the islands were visited and named by Queirós, suggesting that La Encarnación may actually have been Henderson Island, and San Juan Bautista may have been Pitcairn Island.
Pitcairn Island was sighted on 3 July 1767 by the crew of the British HMS Swallow, commanded by Captain Philip Carteret. The island was named after midshipman Robert Pitcairn, a 15-year-old crew member who was the first to sight the island. Robert Pitcairn was a son of British Marine Major John Pitcairn, who was later killed at the 1775 Battle of Bunker Hill in the American War of Independence.
Carteret, who sailed without the newly invented marine chronometer, charted the island at 25°02′S 133°21′W, and although the latitude was reasonably accurate, his recorded longitude was incorrect by about 3°, putting his coordinates 330 km (210 mi) to the west of the actual island. This made Pitcairn difficult to find, as highlighted by the failure of Captain James Cook to locate the island in July 1773.
In 1790, nine of the mutineers from the British naval vessel HMS Bounty, along with the native Tahitian men and women who were with them (six men, 11 women, and a baby girl), settled on Pitcairn Island and set fire to the Bounty. Later inhabitants of the island remained aware of the Bounty's location, which is still visible underwater in Bounty Bay, but the wreckage gained significant attention in 1957 when documented by National Geographic explorer Luis Marden. Although the settlers survived by farming and fishing, the initial period of settlement was marked by serious tensions among them. Alcoholism, murder, disease and other ills took the lives of most mutineers and Tahitian men. John Adams and Ned Young turned to the scriptures, using the ship's Bible as their guide for a new and peaceful society. Young eventually died of an asthmatic infection.
Ducie Island was rediscovered in 1791 by Royal Navy captain Edward Edwards aboard HMS Pandora, while searching for the Bounty mutineers. He named it after Francis Reynolds-Moreton, 3rd Baron Ducie, also a captain in the Royal Navy.
The Pitcairn islanders reported it was not until 27 December 1795 that the first ship since the Bounty was seen from the island, but it did not approach the land and they could not make out the nationality. A second ship appeared in 1801, but made no attempt to communicate with them. A third came sufficiently near to see their house, but did not try to send a boat on shore. Finally, the American sealing ship Topaz, under Mayhew Folger, became the first to visit the island, when the crew spent ten hours on Pitcairn in February 1808. Whalers subsequently became regular visitors to the island. The last recorded whaler to visit was the James Arnold in 1888.
A report of Folger's discovery was forwarded to the Admiralty, mentioning the mutineers and giving a more precise location of the island: 25°02′S 130°00′W. However, this was not known to Sir Thomas Staines, who commanded a Royal Navy flotilla of two ships, HMS Briton and HMS Tagus, which found the island at 25°04′S 130°25′W (by meridian observation) on 17 September 1814. Staines sent a party ashore and wrote a detailed report for the Admiralty. By that time, only one mutineer, John Adams, remained alive. He was granted amnesty for his part in the mutiny.
Henderson Island was rediscovered on 17 January 1819 by British Captain James Henderson of the British East India Company ship Hercules. Captain Henry King, sailing on Elizabeth, landed on 2 March to find the king's colours already flying. His crew scratched the name of their ship into a tree. Oeno Island was discovered on 26 January 1824 by American captain George Worth aboard the whaler Oeno.
In 1832, having tried and failed to petition the British government and the London Missionary Society, Joshua Hill, an American adventurer, arrived. He reported that by March 1833, he had founded a temperance society to combat drunkenness, a "Maundy Thursday Society", a monthly prayer meeting, a juvenile society, a Peace Society and a school.
Traditionally, Pitcairn Islanders consider that their islands officially became a British colony on 30 November 1838, at the same time becoming one of the first territories to extend voting rights to women. By the mid-1850s, the Pitcairn community was outgrowing the island; its leaders appealed to the British government for assistance, and were offered Norfolk Island. On 3 May 1856, the entire population of 193 people set sail for Norfolk on board the Morayshire, arriving on 8 June after a difficult five-week trip. However, just 18 months later, 17 of the Pitcairn Islanders returned to their home island, and another 27 followed five years later.
HMS Thetis visited Pitcairn Island on 18 April 1881 and "found the people very happy and contented, and in perfect health". At that time the population was 96, an increase of six since the visit of Admiral de Horsey in September 1878. Stores had recently been delivered from friends in England, including two whale-boats and Portland cement, which was used to make the reservoir watertight. HMS Thetis gave the islanders 200 lb (91 kg) of ship's biscuits, 100 lb (45 kg) of candles, and 100 lb of soap and clothing to the value of £31, donated by the ship's company. An American trading ship called Venus had in 1882 bestowed a supply of cotton seed, to provide the islanders with a crop for future trade.
In 1886, the Seventh-day Adventist layman John Tay visited Pitcairn and persuaded most of the islanders to accept his faith. He returned in 1890 on the missionary schooner Pitcairn with an ordained minister to perform baptisms. Since then, the majority of Pitcairn Islanders have been Adventists.
In 1898, for the purposes of a murder trial, the Pitcairn Islands were placed by the Colonial Secretary under the jurisdiction of the High Commissioner for the Western Pacific, based in Fiji. The islands of Henderson, Oeno and Ducie were annexed by Britain in 1902: Henderson on 1 July, Oeno on 10 July, and Ducie on 19 December. In 1938, the three islands, along with Pitcairn, were incorporated into a single administrative unit called the "Pitcairn Group of Islands". The population peaked at 233 in 1937. It has since decreased owing to emigration, primarily to Australia and New Zealand.
