A seminal work on the power of nonviolent action, this classic book outlines, in a systematic way, the elements involved in successfully opposing military dictatorships by passive means. This work shows how nonviolent action grows from the fact that all governments depend on the cooperation, or at least the general compliance, of the people they govern and in particular on the loyalty of key institutions. From there, it discusses how, if a government's base of support in society is eroded, it becomes increasingly difficult for it to govern, to the point where it can no longer rely on these crucial institutions of administration, persuasion, and coercion. This edition also considers historical evidence, insists on the importance of advance planning and preparation, and identifies key factors to be taken into account in devising sound strategies and tactics. Tactics and strategies that may be adapted for various circumstances are also included.
