Nonviolent Conflict: Social Movements

Introducing the Topic

Introduction to Social Movements

A single protest rarely changes very much. Lasting change usually comes when people organize, keep the pressure on over months or years, and build support well beyond those who first took to the streets. On the previous pages, we looked at what nonviolence means and at the debate over the legitimacy of nonviolent and violent protest. This page examines social movements, which are among the most important non-state actors in nonviolent conflict. It looks at what social movements are and how they differ from other non-state actors, why they form, the stages they tend to go through, how social media has changed them, and what they achieve.

This is the third of three pages in the Nonviolent Conflict section. This page covers what social movements are, why they form, and how they develop. The first page, Nonviolence and Pacifism, covers the meaning of nonviolence and pacifism. The second page, The Legitimacy of Nonviolent and Violent Protest, covers forms of nonviolent action and the debate over whether nonviolent or violent protest is more effective. Social movements are also listed as non-state actors in the core topic Framing Global Politics, so you can use this page when teaching the core as well.

INTRODUCING NONVIOLENCE

Why Study Social Movements?

But I've learned you are never too small to make a difference.

- Thunberg, 2018

In August 2018, Greta Thunberg, then 15 years old, sat alone outside the Swedish parliament with a sign that read "School strike for climate." Other students began to join her, first in Sweden and then in other countries, under the name Fridays for Future. Thunberg spoke the words above at the United Nations climate conference in Poland that December. On 20 September 2019, just over a year after her first strike, organizers reported that more than 4 million people in 150 countries took part in a single day of climate strikes. However, global carbon emissions have continued to rise since then.

Questions to Consider

  1. Why do some protests grow into movements while others fade away?
  2. How should we judge whether a social movement has succeeded?

Activating Activity: Is It A Social Movement

Social movements are one type of non-state actor. Others include NGOs, political parties, interest groups, and resistance movements. It is not always easy to tell them apart, because they often work on the same issues and use similar methods. For example, a social movement and an NGO might both campaign for action on climate change.

The table below describes eight non-state actors from the last 20 years. You are not expected to know the definition of a social movement yet. Use what you already know to decide which of them are social movements.

ActorDescription
Fridays for FutureStudents in many countries who have gone on strike from school since 2018 to demand action on climate change
Amnesty InternationalAn organization with paid staff, members, and offices around the world that researches and campaigns against human rights abuses
Black Lives MatterA campaign against racism and police violence that began with a hashtag in the United States in 2013 and has no single leader
A one-day march against a rise in bus faresResidents of a city who march to the mayor's office on a single afternoon
The People's Defence Forces in MyanmarArmed groups formed in 2021 to fight the military government that seized power in a coup
A political partyAn organization that puts forward candidates in elections in order to form a government
#MeTooWomen around the world who have shared their experiences of sexual harassment and assault online since 2017 and called for change
A national association of oil companiesAn organization that meets with government ministers to influence energy policy on behalf of its members

Reviewing the Activity

Once you have discussed the prompts with your partner, open this box and compare your responses with the possible responses below. Your responses may differ, because some of these actors are difficult to place.

Identify the actors you consider to be social movements.

  • Fridays for Future, Black Lives Matter, and #MeToo are usually considered social movements.
  • Amnesty International is a non-governmental organization (NGO), although it often works alongside social movements.
  • The People's Defence Forces are an armed resistance movement.
  • The association of oil companies is an interest group.
  • The one-day march is a protest. It could become part of a social movement if it continued and grew.

Outline the features that these social movements have in common.

  • They involve large numbers of ordinary people acting together.
  • They continue over months or years.
  • They share a cause and a sense of belonging to the movement.
  • They work mainly outside formal political institutions, using protest to put pressure on those in power.
  • They are often loosely organized, without a single leader or formal membership.

Distinguish between a social movement and one other type of actor in the table.

  • A social movement has no formal membership or paid staff, while an NGO such as Amnesty International is a formal organization.
  • A social movement tries to influence those in power, while a political party tries to win power through elections.
  • A social movement relies mainly on nonviolent protest, while an armed resistance movement uses force against a government or occupying power.
  • A social movement seeks support from the wider public, while an interest group mainly represents the interests of its own members.
Teacher only box

This activity works well with actors printed on cards so pairs can sort them at their desks. Allow about 15 minutes, including the discussion. Students do not need a definition of a social movement before they begin. Ask them to explain how they sorted the actors before they open the Reviewing the Activity box, which gives possible responses to the prompts. Students can return to their groups after the first section of the lesson content.

What is a Social Movement?

Sidney Tarrow defined social movements as "collective challenges, based on common purposes and social solidarities, in sustained interaction with elites, opponents, and authorities" (Tarrow, 1998, p. 4). In other words, a social movement is a large group of people who share a cause, feel connected to one another, and continue to challenge those in power over a long period of time. A single march is not a social movement, but it can be the start of one.

Charles Tilly (2004) argued that social movements combine three elements.

  • A campaign, which is a sustained and organized effort to make demands of those in power
  • A repertoire of actions, such as marches, rallies, petitions, strikes, and boycotts
  • Public displays of worthiness, unity, numbers, and commitment, which Tilly shortened to WUNC

Movements use WUNC displays to show that their cause deserves to be taken seriously. Large crowds show numbers, shared slogans and colours show unity, and a willingness to keep protesting in difficult conditions shows commitment.

The Global Politics guide lists social movements as one of several types of non-state actors (IBO, 2024). The table below shows how they differ from the others.

ActorMain AimHow It Is Organized
Social movementTo bring about, or to resist, political or social changeLoosely organized networks of people and groups, usually without formal membership
Non-governmental organization (NGO)To provide services or to campaign on a specific issueA formal organization with staff, a budget, and a legal status
Political partyTo win elections and form a governmentA formal organization with members, leaders, and candidates
Interest or pressure groupTo influence policy on behalf of its membersA formal organization that lobbies those in power
Resistance movementTo oppose a government or an occupying power, sometimes with forceVaries from loose networks to armed groups

In practice, these actors often overlap. Social movements usually include formal organizations, which John McCarthy and Mayer Zald (1977) called social movement organizations. Black Lives Matter, for example, is a decentralized movement with local chapters that run their own campaigns, but it also includes the Black Lives Matter Global Network Foundation, which is a registered organization.

Why Do Social Movements Form?

Scholars have offered several reasons why social movements form. The chart below outlines the reasons and explanations.

ReasonExplanationTheorists
GrievancesPeople mobilize when they feel a gap between what they have and what they believe they are entitled to. This is known as relative deprivation.Ted Gurr (1970)
Resource mobilizationGrievances are common, but movements only form when people can gather resources such as money, time, skills, and organizations.John McCarthy and Mayer Zald (1977)
Political opportunityMovements are more likely to form when the political situation changes in their favour, for example when those in power are divided or when movements gain influential allies.Sidney Tarrow (1998)
FramingMovements have to present an issue in a way that persuades people to act.Robert Benford and David Snow (2000)

Applying Framing to Ni Una Menos in Argentina

All three framing tasks can be seen in the Ni Una Menos ("Not One Woman Less") movement in Argentina. The movement began in 2015 after the murder of Chiara Páez, a 14-year-old girl who was killed by her boyfriend. Its organizers presented the killing of women as a problem for the whole of society and a failure of the state to protect women, instead of as a series of private tragedies (diagnostic framing). They called on the government to act, for example by keeping official records of femicides (prognostic framing). The movement's name told supporters that not one more woman should be lost to violence. This gave people a clear reason to take part (motivational framing). On 3 June 2015, women marched in more than 80 Argentine cities, and the movement soon spread across Latin America.

Applying the Explanations to the Gen Z Protests in Nepal

Several explanations in the table above apply to the Gen Z protests in Nepal in 2025. Young Nepalis had long been angry about corruption and a lack of jobs, with about one in five young people unemployed (grievances). Social media posts comparing the wealthy lifestyles of politicians' children with the lives of ordinary Nepalis had spread widely, and they presented corruption as the cause of young people's problems (framing). Young people were also able to organize quickly and at little cost through social media and chat platforms (resource mobilization). On 4 September 2025, the government ordered 26 social media platforms to be shut down, triggering the protests. Within days, large numbers of young people were protesting in the streets, and Prime Minister K. P. Sharma Oli resigned on 9 September.

How Do Social Movements Develop?

Social movements change over time. Building on the work of Herbert Blumer, sociologists often describe four stages in the life of a social movement (Christiansen, 2009).

StageExplanation
EmergenceDiscontent is widespread, but there is little organization. People express their concerns individually or in small groups.
CoalescencePeople become aware that others share their concerns. Leaders emerge, demands become clearer, and mass demonstrations may take place.
BureaucratizationThe movement becomes more organized, with coordinated strategies, formal organizations, and regular contact with those in power.
DeclineMass mobilization comes to an end.

Decline does not necessarily mean failure. Movements can decline for several reasons (Christiansen, 2009).

  • Success, when a movement achieves its goals
  • Failure, when a movement collapses because of internal divisions or poor organization
  • Co-optation, when leaders are drawn to the side of the movement's opponents, for example through offers of jobs or money
  • Repression, when authorities use laws, arrests, or force to break up a movement
  • Becoming part of the mainstream, when a movement's goals are widely accepted by society

Applying the Stages to the Farmers' Protests in India

In 2020, India's government introduced three laws to change how farm produce is sold. Many farmers feared the laws would end the guaranteed prices they received for their crops. Protests began among farmers in the states of Punjab and Haryana (emergence). In November 2020, tens of thousands of farmers marched to Delhi, India's capital, and set up camps on the roads into the city (coalescence). More than 40 farmers' unions formed a coalition, the Samyukta Kisan Morcha, which coordinated the protests and held several rounds of talks with the government (bureaucratization). In November 2021, after a year of protest, Prime Minister Narendra Modi announced that the laws would be repealed, and the farmers left their camps the following month (decline through success).

Limits of the Model

Not all movements pass through these stages in order, and many end before they become organized. Tilly argued that social movements are too varied to follow a fixed set of stages (Christiansen, 2009). Movements can also revive. Black Lives Matter began in 2013, grew after protests in Ferguson, Missouri, in 2014, and reached its largest size in 2020.

Social Media and the Success of Social Movements

Social media has changed how social movements form. A hashtag or a video can lead large numbers of people to protest within days. Earlier movements often needed years of organizing to do the same. Movements can also spread quickly across borders. Fridays for Future grew from one student in Sweden to strikes in 150 countries in just over a year.

However, Zeynep Tufekci (2017) argued that movements that grow this quickly also have weaknesses. They often lack the organizations and decision-making structures that earlier movements built over time. As a result, they can struggle to agree on demands, to negotiate with governments, and to change tactics when circumstances change. Tufekci called this last problem a "tactical freeze" (Tufekci, 2017). Governments have also learned to respond, for example by shutting down the internet, spreading disinformation, or waiting until public attention moves on.

In Nepal, the Gen Z movement had no formal leaders, and its supporters used the chat platform Discord to organize. After the prime minister resigned, more than 10,000 users debated on Discord who should lead an interim government and voted for Sushila Karki, a former chief justice, who was appointed on 12 September 2025.

Judging Success

Whether a movement forms quickly online or slowly over many years, its success can be judged in different ways.

  • Policy change: India's farm laws were repealed in 2021. In Argentina, Ni Una Menos contributed to the creation of a national Registry of Femicides in 2015 and to the legalization of abortion in December 2020.
  • Political change: In Nepal, the elections that followed the 2025 protests were won in March 2026 by the Rastriya Swatantra Party, a party founded only in 2022, and its candidate Balen Shah became prime minister.
  • Cultural change: Some movements change how people think and talk about an issue, even without changing the law. After the killing of George Floyd by a police officer in Minneapolis in May 2020, an estimated 15 to 26 million people in the United States took part in Black Lives Matter protests (Buchanan et al., 2020), and racism in policing became a subject of debate in many other countries.

However, the achievements of social movements are often limited or contested. Fridays for Future involved millions of people, but global carbon emissions have continued to rise. In Nepal, more than 70 people were killed during the protests. Furthermore, it is often difficult to show that a movement caused a change, because governments may have had other reasons to act.

Checking for Understanding: Content Quiz

Choose the best answer for each question.

Which feature best distinguishes a social movement from a single protest?

Tarrow defined social movements as collective challenges in sustained interaction with elites, opponents, and authorities. A single protest can be the start of a movement, but it only becomes one if people continue to act together over time.

What does resource mobilization theory argue?

McCarthy and Zald argued that grievances are common, but movements only form when people can gather the resources needed to act on them. The other options describe relative deprivation, political opportunity, and framing.

Ni Una Menos presented the killing of women as a problem for the whole of society and a failure of the state. Which framing task does this describe?

Diagnostic framing identifies a problem and who is responsible for it. Ni Una Menos argued that the killing of women was a problem for society and the state, instead of a series of private tragedies. Resource framing is not one of Benford and Snow's framing tasks.

India's farmers left their protest camps in December 2021 after the government repealed the three farm laws. Which form of decline does this describe?

Decline means that mass mobilization comes to an end. It does not necessarily mean failure. The farmers ended their protests because the laws they opposed had been repealed.

Each question has more than one correct answer. Select all the answers that apply.

According to Tilly, which of the following do social movements display in public to show that their cause should be taken seriously?

All four are correct. Tilly shortened worthiness, unity, numbers, and commitment to WUNC. Large crowds show numbers, shared slogans show unity, and a willingness to keep protesting in difficult conditions shows commitment.

Which of the following are weaknesses that Tufekci identified in movements that grow quickly through social media?

Tufekci argued that social media allows movements to attract large crowds very quickly, so this is a strength. However, these movements often lack the organizations and decision-making structures needed to agree on demands and to change tactics.

Decide whether each statement is true or false.

Decide whether each statement is true or false.

The main aim of a social movement is to win elections and form a government.

This describes a political party. Social movements try to influence those in power, mainly through protest, although movements sometimes lead to the creation of new parties or help them win support.

Decide whether each statement is true or false.

Widespread grievances are enough on their own to explain why a social movement forms.

Grievances are common, but most do not lead to movements. Resources, political opportunities, and effective framing also help to explain why movements form when they do.

Decide whether each statement is true or false.

A social movement can decline because its goals have become widely accepted by society.

Becoming part of the mainstream is one of the ways a movement can decline. Decline means that mass mobilization ends. This can happen because a movement has succeeded.

Decide whether each statement is true or false.

Political opportunity theory suggests that movements are more likely to form when those in power are divided.

Tarrow argued that movements respond to changes in the political situation, such as divisions among those in power or the support of influential allies.

Assessment Connections

Paper 1, Question 1

Source A

Social movements do not last forever. Some decline because they succeed, as their demands are met and supporters see no further need to protest. Others fail when internal divisions or weak organization cause them to collapse. A movement may also be weakened by co-optation, when its leaders accept jobs or money from those they once opposed. Governments may repress a movement through laws, arrests, or force. Finally, a movement can fade because its goals become so widely accepted that it is no longer needed.

Engagement Project and Extended Essay

Engagement Project. You could explore a youth-led campaign in your community, such as a local climate strike group or a student campaign to change a school or city policy, and use resource mobilization theory as a lens. Interviews with organizers might reveal which resources the campaign depends on and whicdh of the four stages it has reached.

Extended Essay. You could draw on political opportunity theory to ask, "To what extent does political opportunity explain the success of the Gen Z protests in removing Nepal's government in September 2025?" The research could explore the role of long-standing grievances about corruption and unemployment, the government's ban on social media, and the way protesters organized online.

Key Ideas

  • Social movements are sustained over time and loosely organized. This distinguishes them from single protests and from NGOs, political parties, and interest groups.
  • Grievances, resources, political opportunities, and framing together help to explain why movements form.
  • Movements often pass through emergence, coalescence, bureaucratization, and decline, although not always in order.
  • Decline does not necessarily mean failure, and success can be judged by policy, political, or cultural change.

Connections to the Core Topics

  • Power in Global Politics: Social movements rely on power with, by acting together in large numbers. Framing is a form of soft power because it draws people into supporting a cause.
  • Framing Global Politics: Social movements are among the non-state actors listed in the core topics. They often work alongside NGOs and political parties, and they can become formal organizations themselves.
  • Interdependence: Movements such as Fridays for Future and Ni Una Menos have spread quickly across borders, with protesters in one state adopting the methods and slogans of those in another.
