Tristan da Cunha is part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha and has a history going back to the beginning of the 16th century. It was settled by men from military garrisons and ships, who married native women from Saint Helena and the Cape Colony. Its people are multi-racial, descended from European male founders and mixed-race (African, Asian and European) and African women founders.

Discovery

The uninhabited islands of Tristan da Cunha were first sighted in May 1506 during a voyage to India by the Portuguese admiral Tristão da Cunha, although rough seas prevented a landing. He named the main island after himself, Ilha de Tristão da Cunha, which was later anglicised to Tristan da Cunha Island. His discovery appeared on nautical maps from 1509 and on Mercator's world map of 1541. Some sources state that the Portuguese made the first landing on Tristan in 1520, when the Lás Rafael captained by Ruy Vaz Pereira called for water.

17th century Though far west of the Cape of Good Hope, the islands were on the preferred route from Europe to the Indian Ocean in the 17th century; ships first crossed the Atlantic to Brazil on the Northeasterly Trades, followed the Brazil Current south to pass the Doldrums, and then picked up the Westerlies to cross the Atlantic again, where they could encounter Tristan da Cunha. The Dutch East India Company required their ships to follow this route, and on 17 February 1643 the crew of the Heemstede, captained by Claes Gerritszoon Bierenbroodspot, made the first confirmed landing. The Heemstede replenished their supplies with fresh water, fish, seals and penguins and left a wooden tablet with the inscription "Today, 17 February 1643, from the Dutch fluyt Heemstede, Claes Gerritsz Bierenbroodspot from Hoorn and Jan Coertsen van den Broec landed here.".

Thereafter, the Dutch East India Company returned to the area four more times to explore whether the islands could function as a supply base for their ships. The first stop was on 5 September 1646 on a voyage to Batavia, Dutch East Indies, and the second was an expedition by the galliot Nachtglas (Nightglass), which left from Cape Town on 22 November 1655. The crew of the Nachtglas noticed the tablet left by the Heemstede on 10 January 1656 near a watering place. They left a wooden tablet themselves as well, as they also did on Nachtglas Eijland (now Inaccessible Island). The Nachtglas, commanded by Jan Jacobszoon van Amsterdam, examined Tristan da Cunha and Gough Island and made rough charts for the Dutch East India Company. Dutch sailors also stayed on the island for four weeks in 1658, and made their last stop in April 1669, when their idea of utilizing the islands as a supply base was abandoned, probably due to the absence of a safe harbour.

In the 17th century ships were also sent from Saint Helena by the English East India Company to Tristan to report on a proposed settlement there, but that project also came to nothing.

18th century The first survey of the archipelago was made by the French corvette Heure du Berger in 1767. Soundings were taken and a rough survey of the coastline was made. The presence of water at the large waterfall of Big Watron and in a lake on the north coast was noted, and the results of the survey were published by a Royal Navy hydrographer in 1781.

A British naval officer who visited the group in 1760 gave his name to Nightingale Island. John Patten, the master of an English merchant ship, and part of his crew lived on Tristan from August 1790 to April 1791, during which time they captured 3600 seals.

The first known attempt to climb Queen Mary's Peak was in 1793 by the French naturalist Louis-Marie Aubert du Petit-Thouars, but this was without success. He did collect and catalogue hundreds of plants from this expedition.

19th century

During this time American whalers frequented the neighboring waters, and in December 1810 an American named Jonathan Lambert "late of Salem, mariner and citizen thereof," along with an Italian named Thomas Currie (anglicized version) and another named Williams, made Tristan their home, establishing the first permanent settlement on the island.Mackay, Margaret (1963) Angry Island: The Story of Tristan da Cunha, 1506–1963. London: Arthur Barker, p. 30 Lambert declared himself sovereign and sole possessor of the group (which he renamed Islands of Refreshment) "grounding my right and claim on the rational and sure ground of absolute occupancy". Lambert's sovereignty was short lived, as he and Williams were drowned while out fishing in May 1812. Currie was joined, however, by two other men and they began to cultivate vegetables, wheat and oats, and breed pigs.

War having broken out in 1812 between the United States and the United Kingdom, the islands were largely used as a base by American cruisers sent to prey on British merchant ships. This and other considerations urged by Lord Charles Somerset, then governor of Cape Colony, led the British government to authorize taking "possession" of the islands as dependencies of the Cape. The formal proclamation of annexation was made on 14 August 1816. The British wanted to ensure that the French, their repeated enemies, would not be able to use the islands as a base for a rescue operation to free Napoleon Bonaparte from his prison on Saint Helena. Attempts to colonize Inaccessible Island failed.

The islands were occupied by a garrison of British Marines, and a civilian population was gradually built up. Whalers also set up on the islands as a base for operations in the Southern Atlantic.

In January 1817 the first successful climb was made to the peak of Queen Mary's Peak.

A small garrison was maintained on Tristan until November 1817. At their own request William Glass (d. 1853), a Scottish corporal from Kelso in the Royal Artillery, was left behind with his wife, two children, and two masons. Thus began the present settlement. From time to time additional settlers arrived or shipwrecked mariners decided to remain. In 1827 they persuaded five coloured women (these were of mixed race: African, Asian and European) from Saint Helena to migrate to Tristan to become the wives of the five desperate bachelors then on the island. Later, African women from Cape Colony married residents on the island. Other male settlers were of Dutch and Italian origin. As a consequence of this history, the inhabitants are of mixed race. DNA studies have shown that the founding men were primarily of European ancestry.

Glass ruled over the little community from 1817 to 1853 in patriarchal fashion. Besides raising crops, the settlers possessed numbers of cattle, sheep and pigs. Their most lucrative occupation was seal-fishing. The island was still frequented by American whalers. In 1856, 25 people emigrated to the United States, out of a total island population of about 100. The next year 45 of the inhabitants removed to Cape Colony. Since then other younger or more restless members of the community have emigrated there; some took to a seafaring life.

The inhabitants settled on the plain on the north-west of Tristan, as it was the only level land. Here a number of substantial stone cottages and a church were built.

After the death of Glass, the head of the community for some time was a man named Cotton, who had served on a man of war ship, and for three years had been guard over Napoleon at Saint Helena. Cotton was succeeded by Peter William Green (anglicised from Pieter Willemszoon Groen), a native of Katwijk aan Zee, who had settled in the island in 1836. During Green's "reign," the economic condition of Tristan suffered by the loss of ship traffic of the whalers. This was largely due to the outbreak of the American Civil War diverting resources. In addition, the Confederate cruisers CSS Alabama and CSS Shenandoah, captured and burned many Union whaling ships. As a result, the number of ships calling at Tristan considerably diminished and trade languished.

With the opening of the Suez Canal in 1869, together with the gradual transition from sailing ships to coal-fired steam ships, the isolation of the islands increased. They were no longer needed as a stopping port for sailing journeys from Europe to the Far East. Most ships went through the canal for a shorter route.

In 1867, Prince Alfred, Duke of Edinburgh and second son of Queen Victoria, visited the islands. The main settlement, Edinburgh of the Seven Seas, was named in honour of his visit.

In October 1873 the islands were carefully surveyed by the celebrated expedition of HMS Challenger. Captain George Nares recorded that upon the ship's arrival, the men of Tristan came forward offering potatoes, albatross eggs, and other provisions to his crew.. The Captain recorded a total of 15 families and 86 individuals living on the island. This expedition also aided two German brothers named Stoltenhoff, in moving to the mainland at Cape Town. They had been living on Inaccessible Island since November 1871. They were the only ones to have attempted colonization of any island except the main one.

In 1880 the population appears to have attained its maximum. In 1885 the islanders encountered disaster. A poor winter had left them short of food, and a boat sent to barter with a ship offshore was lost with all hands—fifteen men. Only four adult males were left on the island. At the same time a plague of rats—survivors of a shipwrecked vessel—wrought much havoc among the crops. The British government planned to remove all the inhabitants to the Cape, but the majority preferred to remain. Stores and provisions were sent out to them by the British government.

The ravages of the rats rendered the growing of wheat impossible; the wealth of the islanders now consisted of their cattle, sheep, potatoes, and apple and peach trees, and the only form of currency was the potato. The population in 1897 was only 64; in 1901 it was 74, and in 1909, 95.

Tristan da Cunha's residents managed their own affairs without any written laws. The inhabitants have been described as moral, religious, hospitable to strangers, well-mannered and industrious, healthy and long-lived. They lack intoxicating liquors and were said to commit no crimes. , there have been no divorces. They were daring sailors, and in small canvas boats of their own building voyage to Nightingale and Inaccessible islands. They knit garments from the wool of their sheep, are good carpenters, and make serviceable carts.

The Society for the Propagation of the Gospel recruited the first missionary to the island, Rev. William F. Taylor, who served from 1851 to 1856. After his departure, the Bishop of St. Helena attempted to establish an Anglican mission on the island from 1866 onward, and this post was finally filled by Lewis Carroll's youngest brother, the Reverend Edwin Heron Dodgson, who arrived on the island 25 February 1881. Shortly after his arrival he recorded 16 families and 107 individuals living on the island. Reverend Dodgson returned to England in February 1885 and attempted to arrange for the evacuation of the Tristan, meeting with Prime Minister, Lord Salisbury, citing dangerous isolation, but the evacuation was deemed impracticable. Following a disaster at sea that killed fifteen islanders, a large proportion of the working men, Dodgson returned to Tristan in 1886 and remained until December 1889.

20th century In 1906 the islanders passed through a period of distress owing to great mortality among the cattle and the almost total failure of the potato crop. The majority again refused, however, to desert the island, though offered allotments of land in Cape Colony. Similar proposals were made and declined several times since the question was first mooted in 1886.
