Erica Chenoweth. 10/19/2018. “In July, the Trump-era wave of protests started taking a back seat to campaign rallies.” The Washington Post. See full text.Abstract
Erica Chenoweth and Jeremy Pressman contribute to The Washington Post's monthly series on political crowds in the United States.
For 18 months now, as we’ve counted attendance at political gatherings around the United States, we’ve seen crowds in all 50 U.S. states and the District of Columbia. For the first time since President Trump’s inauguration, we found one state with no political gatherings. In all, in July, we tallied 743 protests, demonstrations, strikes, marches, sit-ins, rallies and walkouts in all states and the District — except South Dakota.
Our conservative guess is that between 71,502 and 73,483 people showed up at these political events, although more probably showed up, as well. This number is the lowest in one month that we’ve seen since December 2017. This year, January, March and June included some of the highest protest numbers in U.S. history, and June featured unusually high attendance because of LGBTQ Pride, Families Belong Together (which protested the policy that separated migrant families at the border), and the Poor People’s Campaign, among others.

The Politics of Terror by Erica Chenoweth:
Bringing together both classic and contemporary research, The Politics of Terror provides a systematic introduction to the theory, politics, and practice of terrorism. In addition to offering a comprehensive, evidence-based overview of the subject, Chenoweth and Moore challenge readers to think critically. The book is oriented around a set of empirical, theoretical, and methodological puzzles that arise in the study of terrorism. By encouraging students to engage with these puzzles, and equipping them with the resources to do so thoughtfully, the authors present a nuanced introduction to a complex and crucially important field.

Introducing the Nonviolent Action in Violent Contexts (NVAVC) dataset article by Erica Chenoweth
Scholarship on civil war is overwhelmingly preoccupied with armed activity. Data collection efforts on actors in civil wars tend to reflect this emphasis, with most studies focusing on the identities, attributes, and violent behavior of armed actors. Yet various actors also use nonviolent methods to shape the intensity and variation of violence as well as the duration of peace in the aftermath. Existing datasets on mobilization by non-state actors – such as the Armed Conflict Events and Location (ACLED), Integrated Conflict Early Warning System (ICEWS), and Social Conflict Analysis Database (SCAD) – tend to include data on manifest contentious acts, such as protests, strikes, and demonstrations, and exclude activities like organizing, planning, training, negotiations, communications, and capacity-building that may be critical to the actors’ ultimate success. To provide a more comprehensive and reliable view of the landscape of possible nonviolent behaviors involved in civil wars, we present the Nonviolent Action in Violent Contexts (NVAVC) dataset, which identifies 3,662 nonviolent actions during civil wars in Africa between 1990 and 2012, across 124 conflict-years in 17 countries. In this article, we describe the data collection process, discuss the information contained therein, and offer descriptive statistics and discuss spatial patterns. The framework we develop provides a powerful tool for future researchers to use to categorize various types of nonviolent action, and the data we collect provide important evidence that such efforts are worthwhile.

Journal article on: The Future is a Moving Target: Predicting Political Instability
Previous research by Goldstone et al. (2010) generated a highly accurate predictive model of state-level political instability. Notably, this model identifies political institutions – and partial democracy with factionalism, specifically – as the most compelling factors explaining when and where instability events are likely to occur. This article reassesses the model’s explanatory power and makes three related points: (1) the model’s predictive power varies substantially over time; (2) its predictive power peaked in the period used for out-of-sample validation (1995–2004) in the original study and (3) the model performs relatively poorly in the more recent period. The authors find that this decline is not simply due to the Arab Uprisings, instability events that occurred in autocracies. Similar issues are found with attempts to predict nonviolent uprisings (Chenoweth and Ulfelder 2017) and armed conflict onset and continuation (Hegre et al. 2013). These results inform two conclusions: (1) the drivers of instability are not constant over time and (2) care must be exercised in interpreting prediction exercises as evidence in favor or dispositive of theoretical mechanisms.

New article in Foreign Affairs from Carr Center's Zoe Marks and Erica Chenoweth, with Jide Okeke, delineates how protest movements are succeeding where even global arrest warrants can’t.
A new tide of people power is rising in Africa. On April 2, a nonviolent resistance movement in Algeria succeeded in pressuring Abdelaziz Bouteflika to resign after 20 years as president. Nine days later, protesters in Sudan were celebrating the ouster of Omar al-Bashir, Sudan’s president of 30 years, after a three-month-long uprising against his regime.
The nonviolent overthrows of Bouteflika and Bashir are not aberrations. They reflect a surprising trend across the continent: despite common perceptions of Africa as wracked by violence and conflict, since 2000, most rebellions there have been unarmed and peaceful. Over the past decade, mass uprisings in Africa have accounted for one in three of the nonviolent campaigns aiming to topple dictatorships around the world. Africa has seen 25 new, nonviolent mass movements—almost twice as many as Asia, the next most active region with 16.
Erica Chenoweth and Margherita Belgioioso. 8/5/2019. “The Physics of Dissent and the Effects of Movement Momentum.” Nature Human Behaviour. See full text.Abstract
How do ‘people power’ movements succeed when modest proportions of the population participate?
Here we propose that the effects of social movements increase as they gain momentum. We approximate a simple law drawn from physics: momentum equals mass times velocity (p = mv). We propose that the momentum of dissent is a product of participation (mass) and the number of protest events in a week (velocity). We test this simple physical proposition against panel data on the potential effects of movement momentum on irregular leader exit in African countries between 1990 and 2014, using a variety of estimation techniques. Our findings show that social movements potentially compensate for relatively modest popular support by concentrating their activities in time, thus increasing their disruptive capacity. Notably, these findings also provide a straightforward way for dissidents to easily quantify their coercive potential by assessing their participation rates and increased concentration of their activities over time.
Erica Chenoweth, Deborah Avant, Marie Berry, Rachel Epstein, Cullen Hendrix, Oliver Kaplan, and Timothy Sisk. 9/25/2019. Civil Action and the Dynamics of Violence, Pp. 320. Oxford University Press. See full text.Abstract
This comprehensive study introduces scholars and practitioners to the concept of civil action. It locates civil action within the wider spectrum of behavior in the midst of civil conflict and war, and showcases empirical findings about the effects of civil action in nine cases from around the world. It explains the ways in which non-violent actions during civil war affect the dynamics of violence.
Many view civil wars as violent contests between armed combatants. But history shows that community groups, businesses, NGOs, local governments, and even armed groups can respond to war by engaging in civil action. Characterized by a reluctance to resort to violence and a willingness to show enough respect to engage with others, civil action can slow, delay, or prevent violent escalations. This volume explores how people in conflict environments engage in civil action, and the ways such action has affected violence dynamics in Syria, Peru, Kenya, Northern Ireland, Mexico, Bosnia, Afghanistan, Spain, and Colombia. These cases highlight the critical and often neglected role that civil action plays in conflicts around the world.

"In 1986, millions of Filipinos took to the streets of Manila in peaceful protest and prayer in the People Power movement. The Marcos regime folded on the fourth day.
In 2003, the people of Georgia ousted Eduard Shevardnadze through the bloodless Rose Revolution, in which protestors stormed the parliament building holding the flowers in their hands."

Since the inauguration of Donald Trump, there has been substantial and ongoing protest against the Administration. Street demonstrations are some of the most visible forms of opposition to the Administration and its policies. This article reviews the two most central methods for studying street protest on a large scale: building comprehensive event databases and conducting field surveys of participants at demonstrations. After discussing the broader development of these methods, this article provides a detailed assessment of recent and ongoing projects studying the current wave of contention. Recommendations are offered to meet major challenges, including making data publicly available in near real time, increasing the validity and reliability of event data, expanding the scope of crowd surveys, and integrating ongoing projects in a meaningful way by building new research infrastructure.
