The Trust was established as a body corporate under the David Tonkin government in 1981 by the History Trust of South Australia Act 1981. This Act repealed the Constitutional Museum Act 1978, but does not affect the operation of the South Australian Museum Act 1976, nor the later Aboriginal Heritage Act 1988 or Heritage Places Act 1993. The Board is responsible to the Minister and its functions are laid out in the Act, including: carrying out, or promoting, research relevant to the history of the State; accumulating and classifying data on any subject of significance to the history of the State; accumulating and caring for objects of historical interest; exhibiting objects of historical or cultural interest; maintaining registers of objects of historical significance to the State; managing museums and other premises placed under the care of the Trust, and several other functions. One of its first responsibilities was the care of Constitutional Museum, Australia’s first political museum, later known as Old Parliament House, before reverting to use by the South Australian Parliament in 1995. From 2013, the History Trust has been a member of the Federation of Australian Historical Societies. Reporting to the Minister for the Arts, the Trust's funding and oversight was the responsibility of Arts South Australia until 2018, when the position of Arts Minister was abolished and it was moved, along with Carclew, Patch Theatre Company and Windmill Theatre Company, to the Department of Education. In July 2019, the state budget slashed funding to the History Trust, Carclew and Windmill, as part of "operational efficiency" cuts.
