It may only take 3.5% of the population to topple a dictator with civil resistance
The United States has its own rich history past and present with effective uses of nonviolent resistance. The technique established alternative institutions like economic cooperatives, alternative courts and an underground constitutional convention in the American colonies resulting in the Declaration of Independence. In 20th century, strategic nonviolent resistance has won voting rights for women and for African Americans living in the Jim Crow South.
Today, those seeking knowledge about the theory and practice of civil resistance can find a wealth of information at their fingertips. In virtually any language, one can find training manuals, strategy-building tools, facilitation guides and documentation about successes and mistakes of past nonviolent campaigns.
