Why do organizations choose to use specific nonviolent strategies? In our study of self-determination movements between 1960 and 2005, we find that competition between organizations within the same movement affects the choice of specific nonviolent strategies. Indeed, nonviolent strategies have varying resource requirements and organizations adapt to competition within their movement by copying each other (diffusion), and by diversifying their strategy choices.
