This article introduces the first volume of AHS Classics: Australia and the First World War. It surveys the critical scholarship on the Australian experience of war, taking its cue from Ken Inglis' seminal article, ‘The Anzac Tradition’ (1965), and tracing the development of his challenge to Australian historians over the following five decades. It argues that the adaptability of the Anzac legend, and its assimilation of varied experiences of the First World War, requires both investigation and caution in the production of new histories of events almost a century distant.
