Erica Chenoweth, an assistant professor at the University of Denver, and Maria Stephan, a lead foreign affairs officer with the U.S. State Department, earned the prize for the ideas set forth in their book, “Why Civil Resistance Works: The Strategic Logic of Non-Violent Conflict.” Columbia University Press published the book in 2011.

Chenoweth and Stephan collected and analyzed data on all known uprisings between 1900 and 2006 involving more than 1,000 people that related to a country’s secession, overthrow of a dictatorship or removal of a foreign occupation. They learned that the non-violent campaigns succeeded twice as often as the violent ones — even in the face of brutal repression.

They also found that the governments of countries where the peaceful resistance took place were far more likely to become or remain stable democracies afterward.

In the non-violent campaigns they studied, unarmed civilians used a mix of strikes, boycotts, protests and demonstrations, while bombings, assassinations and armed attacks were predominant among the violent movements.

“The implications of their work are enormous,” said award director Charles Ziegler. “Not only do their findings validate the work done by Gandhi and Martin Luther King Jr., but they shed new light on the political change we’re seeing today, such as the Arab Spring process in Egypt and other Middle Eastern nations.”

Chenoweth, who works in the University of Denver’s Josef Korbel School of International Studies, directs that school’s Program on Terrorism and Insurgency Research. Previously, she was an assistant professor at Wesleyan University in Connecticut.

Stephan, who now works to support the Syrian opposition, previously was assigned to the U.S. Embassy in Kabul, Afghanistan. Before that, she worked with the European/NATO policy office of the U.S. Department of Defense and NATO Headquarters in Brussels.
