Nonviolent resistance refers to methods of protest and civil disobedience without physical violence. It includes acts of omission like refusing to perform expected actions, and acts of commission like performing forbidden actions. Gene Sharp identified 198 methods of nonviolent action. Erica Chenoweth found nonviolent campaigns are more likely to succeed than violent revolutions, with campaigns involving over 3.5% of the population always succeeding. Nonviolent resistance works by claiming the moral high ground, exposing fractures in the opponent's support, inspiring solidarity, and turning stakeholders against each other at "pressure points".
