History


Discovery

The uninhabited islands were first recorded as sighted in 1506 by Portuguese explorer
Tristão da Cunha Tristão da Cunha (sometimes misspelled Tristão d'Acunha; ; c. 1460 – c. 1507) was a Portuguese explorer and naval commander. In 1499, he served as ambassador from King Manuel I of Portugal to Pope Leo X, leading a luxurious embassy presentin ...

On his voyage out from Europe to East Africa and India in command of the Imperial Asiatic Company of Trieste and Antwerp ship, ''Joseph et Therese'', William Bolts sighted Tristan da Cunha, put a landing party ashore on 2 February 1777 and hoisted the Imperial flag, naming it and its neighboring islets the Isles de Brabant.

islands in the Southern Ocean. Captain John Blankett, R.N., also suggested independently to his superiors in August 1786 that convicts be used to establish a British settlement on Tristan. In consequence, the Admiralty received orders from the government in October 1789 to examine the island as part of a general survey of the South Atlantic and the coasts of southern Africa. That did not happen, but an investigation of Tristan, Amsterdam and St. Paul was undertaken in December 1792 and January 1793 by George Macartney, Britain's first ambassador to China. During his voyage to China, he established that none of the islands were suitable for settlement.

The boat, recently donated by the British government, sailed despite rough waters and, although the lifeboat was spotted sailing alongside the ship for some time, it never returned. Various reports were given following the event, with rumours ranging from the men drowning, to reports of them being taken to Australia and sold as slaves. In total, 15 men were lost, leaving behind an island of widows. A plaque at St. Mary's Church commemorates the lost men.


20th century


Hard winter of 1906

After years of hardship since the 1880s and an especially difficult winter in 1906, the British government offered to evacuate the island in 1907. The Tristanians held a meeting and decided to refuse, despite the government's warning that it could not promise further help in the future.

. Due to Tristan da Cunha's isolated archipelago ecology, and increase of tourism with cruise ships and research vessels, invasive species are a particular concern for Tristan da Cunha. The islands' vegetation and mammal species are not equipped to defend against or control introduced species, increasing island vulnerability, due to lack of defensive behavioural mechanisms and slow generational output rates. Efforts to decrease and eradicate invasive flora, fauna, and marine species have been undertaken, including a programme aimed at eradicating predatory invasive mice from Gough Island. The following described invasive species have been known to have harmful effects on the islands' vegetation and native species. Invasive house mice on these islands, have adapted to be 50% larger than average house mice. They are thought to have been accidentally introduced by 19th century seal hunters who would dock on the islands. These mice have adapted by consuming sea bird eggs and chicks (as they nest on the ground). Gathering at night in groups of 9 or 10, the mice gather at the bird's nest to feast. With no natural predators, the invasive mice population is able to expand by producing new generations twice a year. In order to prevent the growth of the invasive mice population and extinction of the Albatross bird species, a 2019 Gough Island mouse eradication project was announced (Grundy, 2018). The RSPB and Tristan da Cunha Government have partnered to spread cereal pellets with

Introduced plants

Tristan da Cunha acquired an estimated 137 non-native vascular plants that can be categorized into four species types; weeds (trees, shrubs, agricultural weeds), grassland species (grasses), garden escapes (vegetables), and other ruderal species. Vascular plants were accidentally introduced in a variety of ways including; impurities in flower or vegetable seeds, seeds or plant fragments from other imported plants and in soil, attached to containers, cars or people. The majority of invasive weed species that has been introduced to the island are spread by seed and cover 50% of arable land in widely distributed patches. These species include prickly sow-thistle (''

''). Whether a species is distributed locally or widely depends on the seed's dispersal mechanisms; larger seeds that have not adapted to wind dispersal will be distributed locally, while smaller seeds have adapted to wind dispersal will be widely distributed. The invasive plants have had several negative impacts on native island plant species, including the competitive exclusion of many such species. The out-competition will and can alter the structure of plant communities and the quality of the islands' soil. Introduced vegetation has altered long-term carbon storage as well as the reduction of CO2 in the atmosphere. Native plants such as fern bushes, '' Phylica'' bushes, fern brakes, mires, and bogs, contain high organic content matter which functions as storage for carbon. With the introduction of harmful species, the islands will see a decrease in carbon storage of both the soil and vegetation. With multiple changes occurring within the soil due to invasive plant species, the nutrient cycle is bound to be negatively influenced. Invasive plants are also affecting the human population of Tristan da Cunha by being disease carriers and becoming agricultural pests in gardens and pastures. The alien plants are able to survive and continue to grow and spread successfully on the islands because they have the ability to naturalize in temperate regions and have limited necessities needed to survive. The islands' isolation increases archipelago ecology uniqueness which increases susceptibility for foreign invaders. A small human population with minimal development encourages flora and fauna development within a limited food web which increases the invasive species abilities for self-defense. Plants are being controlled by taking surveys of the invasive species, evaluating their impact on biodiversity, and evaluating the feasibility of their eradication. It would be nearly impossible to try and eradicate all invasive plant species so scientists are narrowing down to control particular species based on their impact and feasibility to eradicate. Mitigation plans that are taking place on Tristan are time-consuming and labor-intensive that will take several years using mechanical and chemical procedures.

The biodiversity of marine life is limited given the islands' isolation, making identifying the impacts of invasion difficult. While much of the marine life is unknown there has been an invasive species identified in the waters around the islands. This species is the South American silver porgy ('' Diplodus argenteus argenteus'') which is thought to have sought refuge in the area due to the wreck of an oil platform off the coast of Tristan in 2006. The silver porgy is omnivorous but is not linked to the consumption of the valued lobster populations that the islanders fish.

Besides subsistence agriculture, major industries are commercial fishing and government. Major export industries are the Tristan rock lobster (''

Transport

and is not generally accessible to air travel, though the wider territory is served by Saint Helena Airport and RAF Ascension Island. Fishing boats from South Africa service the islands eight or nine times per year. The RMS ''Saint Helena'' used to connect the main island to St Helena and South Africa once each year during its January voyage, but has done so only a few times in the last years, in 2006, in 2011, and most recently in 2018. In the same year the RMS St. Helena was withdrawn from service. Three ships regularly service Tristan da Cunha, with typically fewer than a dozen visits a year. Other vessels may occasionally visit the island. The harbour at Edinburgh of the Seven Seas is called Calshot Harbour, named after the place in Hampshire, England where the islanders temporarily stayed during the volcanic eruption.


Tourism

Unlike Saint Helena with its airport, hotels and restaurants, due to its remoteness Tristan da Cunha has a very small tourism industry. Tourists are welcome and the hospitality of the population is famous, but as it can only be reached by South African fishing trips in rough seas with limited vacancies, a trip must be planned months in advance, and only after a mandatory visit request is approved by the Island Council. Occasional boats or cruises may include a short visit to the island in their itinerary; but as there is no deep harbour, setting ashore is highly dependent on the maritime conditions. With all these limitations and in spite of the spectacular natural landscapes, visiting the territory is an attractive challenge for more adventurous travellers who can afford the time and money to get there. All visitors staying on Tristan must have a confirmed and fully paid return ticket, health insurance to include cover in case of medical evacuation to Cape Town, and sufficient funds to cover their entire stay. There are no hotels on the island. A visitor can rent a guest house (catered or self-catering) or stay in a private home on a full-board basis. There is a Tourism Post Office that sells souvenirs that might take months to arrive if ordered online.

. Since 1998, each Administrator has usually served a three-year term (which begins in September, upon arrival of the supply ship from Cape Town). Fiona Kilpatrick and Stephen Townsend were exceptions to this rule, having taken up their job-share office in January 2020. The Administrator and Island Council work from the Government Building, which is the only two-storey building on the island. The building is sometimes referred to as "Whitehall" or the "H'admin Building" and contains the Administrator's Office, Treasury Department, Administration Offices, and the Council Chamber where Island Council meetings are held. Policing is undertaken by one full-time police inspector and three special constables. Tristan da Cunha has some legislation of its own, but the law of Saint Helena applies generally to the extent that it is not inconsistent with local law, insofar as it is suitable for local circumstances and subject to such modifications as local circumstances make necessary.


Chief Islander

The Island Council is made up of eight elected and three appointed members, who serve a three-year term which begins in February or March. A separate but simultaneous vote is held to select the Chief Islander, who is the community's political leader. James Glass was re-elected to the position in March 2022 to a record-breaking fifth term in the role.


Demographics

Tristan da Cunha recorded a population of 243 in the June 2021 census. The only settlement is Edinburgh of the Seven Seas (known locally as "The Settlement"). The current residents are thought to have descended from fifteen outside ancestors, eight male and seven female, who arrived on the island at various dates between 1816 and 1908. The men were European, and the women were mixed race. Now all of the population has mixed ancestry. In addition, a male contributor of eastern European / Russian descent arrived in the early 1900s. In 1963, when families returned after the evacuation due to the 1961 volcanic eruption, the 200 settlers included four Tristan da Cunha women who brought with them new English husbands. The female descendants have been traced by genetic study to five female founders, believed to be mixed-race (African, Asian and European descent) and from Saint Helena. The historical data recounted that there were two pairs of sisters, but the

There is "evidence for the contribution of a hidden ancestor who left his genes, but not his name, on the island." Another four instances of non-paternity were found among male descendants, but researchers believed their fathers were probably among the early island population. There are eighty families on the island.


Language

Tristan da Cunha's isolation has led to development of its own accent. In popular writing, it has been described by the writer Simon Winchester as "a sonorous amalgam of Home Counties lockjaw and 19th century idiom, Afrikaans slang and Italian." Unique features of "Tristan da Cunha English" include the non- diphthongization of the vowel of (such as that "face" is pronounced ), and h-insertion in words like ''" pple"'' and ''" fter"'' (such as that "island" and "highland" are

In February 2013, the Tristan Post Office issued a set of four Song Project stamps featuring island musical instruments and lyrics from Song Project songs about Tristan's volcano and wildlife. In 2014, the project broadened its scope and continues as the International Song Project.

The new hospital was funded by the UK Department for International Development with the intention the improved facilities would allow more procedures to be performed locally by visiting specialists, and therefore reduce the need for expensive referrals to Cape Town.

There are also normally two expatriate and four local nurses, as well as two dental technicians, a hospital manager and ancillary staff.

such as " Barbara Allen" and " The Golden Vanity". She also describes how dance was an important element of life on Tristan; well-known dances such as step dances, waltzes, polkas, mazurkas and schottisches were common, as well as many unique traditional dances such as "The Donkey Dance", "The Pillow Dance", "The Chair Dance" and something called "Tabby Oaker's Big Toe" which involved displaying one's feet. It seems that the music and dance of Tristan was ultimately derived from English traditions, but various peculiarities had developed.


Crime

No one has ever been arrested for crime by the single policeman on the island.

were all historically played on the island. It has been reported that football was introduced to the locals in the 1920s by Rev. Henry Rogers, and it remains the island’s favourite sport. Rose, Henry’s wife, wrote about informal kick-abouts continuing for years, and these fast became a part of Tristanian culture. The islanders would split themselves into two teams and play friendly matches, especially on dates of special occasions, such as weddings, christenings etc. In 1940 Tristan da Cunha's footballers played their first "international" game against the crew of a Norwegian ship. No record remains of the score. In the ensuing years, the game flourished, with the islanders playing matches against crews from vessels of various nationalities, including ships from the Royal Navy. With live transmissions of televised football, the sport regained its former popularity. Tristan da Cunha FC was formed in 2002. A local fishing company bought them a kit (white shirts and blue shorts). They had a very basic pitch on American Field, named in recognition of the American forces stationed there during

In recent times, the club's numbers have dropped to a level where only 5-a-side matches are being played.
