Erica Chenoweth is a pioneering academic whose ground breaking study on strategic non-violence demonstrated that movements that use non-violent tactics when fighting for the over-through of a regime are twice as likely to succeed as movements that use violence as a tactic. Her book, Why Civil Resistance Works: The Strategic Logic of Non-Violence, co-authored with Maria J. Stephan, provides an authoritative study of how and when non-violent movements succeed in their goals of overthrowing a regime. Chenoweth discusses her book, some of the current movements she is studying and tells Mark how growing up in Dayton, Ohio to helped propel her to a career in international relations.
