Book excerpt: This nationally-acclaimed book shows how popular movements used nonviolent action to overthrow dictators, obstruct military invaders and secure human rights in country after country, over the past century. Peter Ackerman and Jack DuVall depict how nonviolent sanctions--such as protests, strikes and boycotts--separate brutal regimes from their means of control. They tell inside stories--how Danes outmaneuvered the Nazis, Solidarity defeated Polish communism, and mass action removed a Chilean dictator--and also how nonviolent power is changing the world today, from Burma to Serbia.
