Book excerpt: A History of South Australia investigates South Australia's history from before the arrival of the first European maritime explorers to the present day, and examines its distinctive origins as a 'free' settlement. In this compelling and nuanced history, Paul Sendziuk and Robert Foster consider the imprint of people on the land - and vice versa - and offer fresh insights into relations between Indigenous people and the European colonisers. They chart South Australia's economic, political and social development, including the advance and retreat of an interventionist government, the establishment of the state's distinctive socio-political formations, and its relationship to the rest of Australia and the world. The first comprehensive, single-volume history of the state to be published in over fifty years, A History of South Australia is an essential and engaging contribution to our understanding of South Australia's past.
