The son of Richard Geoffrey Champion de Crespigny, , and Kathleen Cavenagh Champion de Crespigny, née Cudmore, Richard Rafe Champion de Crespigny was born in Adelaide in 1936. He married Christa Boltz in Turner, Australian Capital Territory on 19 May 1959.
Education
De Crespigny received his tertiary education at the University of Cambridge and the Australian National University. During his early years as a scholar and academic, de Crespigny benefited from the guidance of Geoffrey Elton and sinologists such as Hans Bielenstein, Otto van der Sprenkel, Fang Chao-ying, Liu Ts'un-yan, and Göran Malmqvist, and he developed an interest in the late Han dynasty through the historical novel Romance of the Three Kingdoms. His doctoral dissertation of 1968 on the development of the Chinese empire in the south and the origins of the Three Kingdoms state of Wu has provided the basis for much of his later work.
Publications
De Crespigny's publications include China: The Land and its People ; China This Century, both discussions of modern China. His most significant works, however, are those concerned with the Later Han dynasty and the Three Kingdoms period. Among these are Northern Frontier: The Policies and Strategy of the Later Han Empire ; while Emperor Huan and Emperor Ling and To Establish Peace provide an annotated translation of the chronicle for the years 157 to 189 and 189 to 220 from the Zizhi Tongjian of Sima Guang respectively. He has also published more than twenty articles in Australia and overseas. Generals of the South, published in 1990, narrates the rise of the Sun clan and the formation of the Three Kingdoms tripartite. It builds on the broad range of his translation experience and is telling about his historical interests. Like Northern Frontier, the work focuses on strategies, campaigns, and personalities. The approach owes a great deal to the narrative tradition of the historical novel Romance of the Three Kingdoms but Generals of the South also discusses the population and development of southern China from the second century AD. In dealing with the military defence of the south via the boundary of the Yangtze River, it presents the best discussion of the Battle of Red Cliffs and early Chinese riverine warfare available in English. The work also provides an important prelude to further research into the political and cultural divisions of the Northern and Southern dynasties. In 2007, A Biographical Dictionary of Later Han to the Three Kingdoms 23–220 AD was published by Brill as a companion to Michael Loewe's biographical dictionary dealing with the Qin, Former Han, and Xin periods 221 BC – 24 AD. De Crespigny's more recent publications include Imperial Warlord, a biography of Cao Cao, which was awarded the Stanislas Julien Prize for 2011 by the French Académie des Inscriptions et Belles-Lettres. In 2016 Brill published Fire over Luoyang, a narrative and analytical history of Later Han.
