Anthony Reid was a New Zealand-born historian of Southeast Asia. His doctoral work at Cambridge University examined the contest for power in northern Sumatra, Indonesia in the late 19th century, and he extended this study into a book The Blood of the People on the national and social revolutions in that region 1945–49. He is most well known for his two volume book "Southeast Asia in the Age of Commerce", developed during his time at the Research School of Pacific (and Asian) Studies, Australian National University in Canberra. His later work includes a return to Sumatra where he explored the historical basis for the separate identity of Aceh; interests in nationalism, Chinese diaspora and economic history, and latterly the relation between geology and deep history. Professor Reid taught Southeast Asian history at University of Malaya (1965–1970) and Australian National University (1970–1999). He became the founding director of the Southeast Asia Center, University of California, Los Angeles, 1999–2002, and then the founding director of Asia Research Institute (ARI) at the National University of Singapore (NUS), 2002–2007. He retired from NUS in 2009. Thereafter he was based in Canberra as Professor (Emeritus) at the Australian National University. As a writer of fiction he styled himself Tony Reid. He was the son of John S. Reid, a New Zealand diplomat who held postings in Indonesia, Japan and Canada in the 1950s and 1960s.
2.5 stars to be exact for the amount of research n details the author put in. But this is purely an academic piece and without a good background of Indonesia's history and geography, this books is a chore to digest.
