In anthropology, first contact is the first meeting of two communities previously without contact with one another. Notable examples of first contact are those between the Spanish Empire and the Arawak in 1492; and the Aboriginal Australians with Europeans in 1788 when the First Fleet arrived in Sydney. Such contact is sometimes described as a "discovery", such as the British and United States did by creating the legal theory of the "Doctrine of Discovery". It is generally the more technologically complex society that is able to travel to new geographic regions to make contact with those more isolated, less technologically complex societies. However, some object to the application of such a word to human beings, which is why "first contact" is generally preferred. The use of the term "discovery" tends to occur more in reference to geography than cultures; for an example of a common discovery debate, see Discoverer of the Americas. The fascination with first contact has gone through many transformations since the Age of Discovery, one of the earliest narratives being about contacting the Ten Lost Tribes and Prester John, and continues today as a trope in science fiction about extraterrestrial first contact, as well as being manifest in contemporary space exploration (for example the Pioneer plaque). Establishing contact with uncontacted peoples is still attempted, despite the negative effects, history and opposition by indigenous peoples, advocacy groups and specialized institutions like FUNAI. Consequences The historical record indicates that when one culture is significantly more technologically advanced than the other, this side will be favored by the disruptive nature of conflict, often with dire consequences for the other society, but the introduction of disease plays a critical role in the process. More-isolated peoples who lived across broader territories in low-density succumbed to the illnesses brought from the comparatively-higher density of Europe. The Indigenous populations simply had not had the time to develop immunity to the foreign diseases, all of which introduced at once, to which the more urbanised European populations had had many years to develop some population immunity. History Long before contemporary uncontacted peoples, there were many more cases of communities and states being isolated from each other, sometimes only having poor knowledge of each other and poor contact. One such case is the poor formal contact between Europe and China in the course of the long history of the Silk Road trade and later contact with the
