"Claim-Making and Large-Scale Historical Processes in the Late Twentieth Century," held March 7-9, 1997, at Stanford University, was an experimental workshop to preview the dimensions on the eve of the twenty-first century that the MacArthur Foundation Consortiumon Challenges to the Study of International Peace and Cooperation, will explore over the next three years: war and institutions of violence; globalization; society and the ecosphere; and identity and social power. The idea was to examine these dimensions as large structural macro-historical processes and also to look at how these processes are immanent in the political and cultural claims made by contending actors. All of the workshop panels brought out issues of several dimensions. The first panel, on Globalization and Social Claims, looked at processes of globalization and also at society and the ecosphere. The second panel, State Formation and Claim-Making, focused on the dimensions of war and institutions of violence and also identity and social power. The third panel, Identities and Social Power, was on that dimension, largely in the context of globalization. The fourth panel, a roundtable on Claims to Sovereignty in the Former Soviet Union, was most related to the dimension of war and institutions of violence.
