As one of a series of Ge Zhaoguang’s lecture notes, the book is a collection of lecture notes on Methodology of Asian History Studies developed by Ge for PhD students, which have been improved over repeated lecturing of more than 10 years since 2011. The book consists of 13 lectures in four units, covering the potential of Asian history studies and academic literature on Asian history in the East and the West, with focus on studies and literature on Eastern Asian seas in the early modern time. This book examines the methodological underpinnings of Asian history studies through case studies and discusses how to study the history of China as part of Asian history and observe the surrounding regions from the perspective of China to gain a better understanding of how their history is connected. Each unit begins with a question that invites readers to think about the importance of Asian history studies and concludes with a discussion that serves as a springboard for further research. A list of recommended reading materials is also provided at the end of each unit. This history book for PhD students also provides important information on approaches to regional history.
