The following essays originated in a session of the Social Science History Association in October, 1976. Two of the participants, Bernard S. Silberman and Alfred J. Rieber, were asked to prepare studies of bureaucracy in Japan and Russia which also dealt with the problems of political power relationships in developing bureaucracies. A third participant, Cyril E. Black, was asked to compare, criticize, and synthesize the first two papers in a third paper of his own. Briefly, the substantive point of these essays as a group is that they deal with the effect of political decisions in achieving certain changes in economic, technical, and military structures and operations. They focus attention on the effects within a complex apparatus set up to administer those political decisions, the state bureaucracy. The essays themselves reveal, and Black’s synthesis details, that the points of similarity between Japan and Russia as they change across time are as numerous and instructive as are the differences. In this introduction, I will call attention to some aspects of these studies which, although technical, are nevertheless important to the research enterprise they represent.
