Tony Ballantyne (born Dunedin, 1972) is a New Zealand historian whose works examined the development of imperial intellectual and cultural life in Ireland, India, New Zealand, and Britain. After completing his schooling at King's High School, Dunedin, he graduated BA at the University of Otago and obtained a PhD at the University of Cambridge under the supervision of Professor Christopher Bayly. He currently is Pro-Vice-Chancellor (Humanities) and Director of the Centre for Research on Colonial Culture at the University of Otago, but has previously taught at Washington University in St. Louis, the University of Illinois, and the National University of Ireland. In 2012 he was elected as a Fellow of the Royal Society of New Zealand. He has been a prominent advocate for the value of history and the humanities in New Zealand.
His work is an important example of the 'new imperial history', a tradition of scholarship that sees colonialism as a cultural undertaking as well as a political and economic project. He is best known for forwarding a new model for analyzing the empire's development in his Orientalism and Race (2002) and Between Colonialism and Diaspora (2006). In both works he suggested that the structure of the British empire was like a web, with 'vertical' connections developing between Britain and its colonies and 'horizontal' connections linking various colonies directly. He has suggested that the key work of imperial historians is to reconstruct these 'webs of empire' in order to understand how the empire operated and the ways in which it incorporated new lands and peoples. More specifically, Orientalism and Race introduced a new analysis of the "orientalizing" texts of British officials in colonial India and their attempts to decode both Hinduism and Sikhism more broadly in terms of their understandings of Aryanism and race; at the same time it examined similar discourses directed toward understandings of Maori as first "Semitic", then Indo-Aryan, and ultimately, Maori reconfigurations of Christianity on their own terms.
