Tristan da Cunha supports itself through a substantial fishing industry based around the Tristan rock lobster, including a fish-freezing plant. Some income is also earned from the sale of stamps to philatelists, and handicrafts. Apart from capital projects, it has been financially independent from the UK since 1980.
The islands were discovered in 1506 by a Portuguese admiral, Tristão de Cunha. The first occupation of the island was the British garrison placed there in 1816, some of whom elected to stay on after its withdrawal; by 1886 it had a population of 97. Missionaries provided services as priests, teachers, honorary commissioners and magistrates in the first half of the 20th century, but otherwise the islanders were virtually isolated until a meteorological and wireless station was built there during the Second World War. In 1948, a crawfish industry began, providing employment.
In 1961, a volcano erupted near the settlement of Edinburgh and the entire island had to be evacuated; a few have since settled in the UK but most islanders chose to return in 1963.
The Governor of St Helena is concurrently Governor of Tristan da Cunha. Locally, there is an administrator (also the magistrate), and an island council with three ex-officio and eight elected members, one of whom must be a woman.
