Important publication on the origin, history and development of the Republic of China during the twentieth century. This five-volume publication presents the proceedings of a major international symposium devoted to the history of the Republic of China. Bringing together contributions from leading scholars, the work examines the political, military, economic and social transformations of China from the 1911 Revolution through the mid-twentieth century. Each volume focuses on a specific historical phase, offering detailed analyses grounded in archival research and contemporary historiography. The series is organized into five chronologically structured volumes, each addressing a decisive phase in the development of the Republic of China. The first volume analyses the 1911 Revolution and the collapse of the Qing dynasty, focusing on revolutionary networks and institutional change. The second volume examines the early republican period marked by political fragmentation and competing power structures. The third volume explores the Northern Expedition and the subsequent period of political tutelage under the Nationalist regime, emphasizing state-building and ideological consolidation. The fourth volume is devoted to the War of Resistance Against Japan, addressing military operations, international relations and societal mobilization. The fifth volume studies the post-war reconstruction years, highlighting economic recovery, governance reforms and modernization efforts. Across all volumes, the contributions reflect a conference-based scholarly approach, combining empirical research with interpretative analysis, and collectively form a foundational reference work for the study of twentieth-century Chinese history. The Compilation Committee of the Symposium on the History of the Republic of China was established to organize and publish the proceedings of a major scholarly conference held in Taipei in 1981. The project reflects the institutional effort of the Republic of China to document and interpret its modern history through academic collaboration. Such initiatives are closely linked to national historical institutions such as Academia Historica, which play a central role in preserving archives and promoting research on Republican Chinese history.
