The Black War was a period of violent conflict between British colonists and Aboriginal Tasmanians in Van Diemen's Land (present-day Tasmania) that intensified from the mid-1820s and effectively ended in early 1832. The conflict was fought largely as guerrilla warfare on both sides. Estimates place Aboriginal deaths at 600 to 900, with more than 200 British colonists also killed, though historians note recorded figures likely undercount total deaths.
When a British penal settlement was established in Van Diemen's Land in 1803, the Aboriginal population is estimated to have been between 3,000 and 7,000 people. Relations between colonists and Aboriginal people were initially marked by sporadic violence over competition for game and the abduction of Aboriginal women and children. Conflict escalated sharply from 1824 as British settlement expanded rapidly over Aboriginal land, with Aboriginal attacks on colonists rising from an average of 1.7 per year (1803–1823) to 18 per year (1824–1826).
Governor George Arthur issued proclamations authorising settlers to use force against hostile Aboriginal groups, and in November 1828 declared martial law in the settled districts—a measure that remained in force for more than three years. Military and settler patrols conducted frequent raids on Aboriginal encampments, often resulting in multiple deaths. In October–November 1830, Arthur organised the "Black Line," a large-scale military operation involving roughly 2,200 men intended to drive hostile Aboriginal nations into the Tasman Peninsula. The campaign failed to achieve its goal, capturing only a small number of Aboriginal people.
Conciliation efforts led by George Augustus Robinson, working with Aboriginal negotiators including Truganini and Mannalargenna, proved more successful than military action. Through a series of "Friendly Missions" in 1830 and 1831, Robinson's parties persuaded surviving Aboriginal groups—including those led by Montpelliatta, Tongerlongeter, and Umarrah—to surrender. This surrender, completed in December 1831 and formalised in Hobart in January 1832, effectively ended the Black War; martial law was revoked that month.
Following the conflict, nearly all remaining Aboriginal Tasmanians were removed from the mainland between 1832 and 1835 and eventually relocated to the Wybalenna Aboriginal Mission on Flinders Island. Of the 220 people initially relocated, disease and low birth rates reduced the population to 46 by the time the mission closed in 1847.
Historians disagree on death tolls, population estimates, and characterisation of the conflict. Some historians and genocide scholars, including Raphael Lemkin, Robert Hughes, James Boyce, and Lyndall Ryan, have described the events as genocide. Others, including Henry Reynolds and Nicholas Clements, argue that while individual settlers may have supported extermination, colonial authorities did not pursue an official policy of destroying the Aboriginal population. Historian Keith Windschuttle's substantially lower death-toll estimates have been widely challenged by other historians.
