She stresses that international-scale actions (like threats or outcomes of war, and political and economic inequalities) have a major effect on domestic events (like revolutions). This effect can be explained as the outside effects lead to increased destabilization and political crises (financial crisis, elite divisions, mobilization of groups sensing political opportunity) which in turn increases the likelihood that revolutionary forces will arise and act. Skocpol notes that while elites are important, ordinary citizens are also vital, as supported by the fact that most successful revolutions were aided by urban and peasants mobilizations.
