Scholar Gene Sharp reviewed thousands of instances of nonviolent struggle and catalogued 198 different methods that were used in those encounters. At one point he called these methods "weapons," to emphasize that they are used in conflict situations. He listed them and gave historical examples of each in his 1973 book The Politics of Nonviolent Action. He grouped them into three broad categories: protest, noncooperation, and intervention, and then he further broke those into smaller classifications.
