History of Tasmania
Tasmania was inhabited by an indigenous population, the Tasmanian Aborigines, and evidence indicates their presence in the territory, later to become an island, at least 35,000 years ago. At the time of the British occupation and colonisation in 1803 the indigenous population was estimated at between 3000 and 10,000. Historian Lyndall Ryan's analysis of population studies led her to conclude that there were about 7000 spread throughout the island's nine nations; Nicholas Clements, citing research by N.J.B. Plomley and Rhys Jones, settled on a figure of 3000 to 4000. The combination of the so-called Black War, internecine conflict and, from the late 1820s, the spread of infectious diseases to which they had no immunity, reduced the population to about 300 by 1833. Almost all of the indigenous population was relocated to Flinders Island by George Augustus Robinson. Until the 1970s, most people thought that the last surviving Tasmanian Aborigine was Trugernanner, who died in 1876. However this "extinction" was a myth, as documented by Lyndall Ryan in 1991.
History of Australia
Many events illustrate violence and resistance as Aborigines sought to protect their lands from settlers and pastoralists who attempted to establish their presence. In May 1804, at Risdon Cove, Van Diemen's Land, perhaps 60 Aborigines were killed when they approached the town. The British established a new outpost in Van Diemen's Land (Tasmania) in 1803. Although Tasmanian history is amongst the most contested by modern historians, conflict between colonists and Aborigines was referred to in some contemporary accounts as the "Black War". The combined effects of disease, dispossession, intermarriage and conflict saw a collapse of the Aboriginal population of Tasmania from a few thousand people when the British arrived, to a few hundred by the 1830s. Estimates of how many people were killed during the period begin at around 300, though verification of the true figure is now impossible. In 1830 Governor Sir George Arthur sent an armed party (the Black Line) to push the Big River and Oyster Bay tribes out of the British settled districts. The effort failed and George Augustus Robinson proposed to set out unarmed to mediate with the remaining tribespeople in 1833. With the assistance of Truganini as guide and translator, Robinson convinced remaining tribesmen to surrender to an isolated new settlement at Flinders Island, where most later died of disease.
