This presentation introduces ‘The Politics of Warring-States Japan, 1467-1600,’ a new collection of data covering political and military relations between warlords in Japan during its warring-states period, from 1467-1600. The data covers a wide variety of political phenomena from the period, including battles and wars, territorial conquest, and alliance formation, among others. The presentation will introduce the data, present descriptive statistics of key variables of interest, and reflect on how the data speak to broader theories of international relations and conflict. The presentation should be of interest to scholars of Japanese history, Early Modern East Asia, civil conflict, and international relations theory, among others. Nicholas Anderson is a Visiting Scholar with the Institute for Security and Conflict Studies at the Elliott School of International Affairs at George Washington University, and a Ph.D. Candidate in Political Science at Yale University. Mike Mochizuki, Japan-US Relations Chair in Memory of Gaston Sigur at the George Washington University, will serve as moderator for the audience Q&A.
