Legitimacy is the recognized right of a political actor or institution to exercise authority. Power becomes authority when people and other actors see its use as appropriate, rather than complying simply through fear or necessity.

State legitimacy and government legitimacy

State legitimacy refers to acceptance of the state itself, including its institutions, territorial framework and claim to exercise public authority. Government legitimacy refers to acceptance of the specific leaders and administration that currently control those institutions.

Citizens can reject a government without rejecting the state. The reverse is also possible: a government may function effectively even when the state’s territorial boundaries or political system are disputed. Audience matters too. A government might be accepted at home but rejected internationally, or recognized by other states despite having little popular consent domestically.

Legitimacy and sovereignty

Sovereignty is supreme authority within a territory and independence from external authority. Sovereignty identifies where final authority is claimed to lie. Legitimacy asks whether people regard that claim as rightful.

A sovereign state may therefore have weak legitimacy. At the same time, an actor without full sovereign status can still gain substantial public or international recognition. International recognition supports external sovereignty and may strengthen legitimacy, but it cannot by itself create domestic consent, effective governance or citizen welfare.

Sources of legitimacy

These sources often overlap. They may reinforce each other, though they can also conflict.

Liberals emphasize consent, representative institutions, fair elections, transparency and rights. Realists place more weight on effective control, order and recognition by other states. For constructivists, history, ideology and national identity shape shared beliefs about rightful rule. Feminist and postcolonial perspectives instead ask whose identity is represented and whether apparently legitimate institutions reproduce gendered or colonial exclusions.

South Africa’s 2024 election

South Africa’s state legitimacy rests partly on the constitutional settlement established after apartheid and a national identity linked to democratic transition. In the 2024 South African general election, the African National Congress lost its parliamentary majority. Even so, the competitive election and later formation of a coalition government showed that the legitimacy of the state’s electoral institutions could survive declining support for the former governing party.

The case separates government legitimacy from state legitimacy. Dissatisfaction with performance, welfare provision and governance weakened one party’s mandate, but it did not necessarily amount to rejection of the constitutional state. It also connects legitimacy with representation, equality and development, since continued acceptance depends partly on whether institutions address severe social and economic divisions.

Taiwan’s 2024 presidential election

In Taiwan’s 2024 presidential election, voters selected Lai Ching-te through competitive electoral procedures, giving the incoming government a domestic mandate. Domestic legitimacy is supported by regular transfers of authority, political participation and institutional performance.

Yet Taiwan’s restricted diplomatic recognition shows that internal legitimacy and external sovereignty aren’t identical. Many governments maintain practical relations with Taiwan while withholding formal state recognition. Domestic consent therefore exists alongside contested international status.

Challenges to legitimacy are actions or conditions that weaken recognition of a state’s or government’s right to exercise authority. They can come from citizens and domestic political groups, or from governments, international organizations and other external stakeholders.

Internal and external challenges

Internal challenges develop when people face political exclusion, economic hardship, social division or insecurity. A state may lose acceptance if it fails to govern its territory effectively, provide basic welfare or maintain predictable public order.

The methods authorities use to keep control can also damage legitimacy. Excessive force, threats, oppression, political violence and human rights violations suggest that obedience depends on coercion rather than consent. These practices link legitimacy directly to the thematic studies of rights and justice and peace and conflict.

External actors can challenge legitimacy by withholding recognition, imposing sanctions, condemning abuses or recognizing an alternative authority. This pressure may strengthen domestic opposition. Governments, however, may present it as foreign interference and defend their position through appeals to sovereignty or nationalism.

Realists may assess legitimacy partly through effective control and the maintenance of order. Liberals see order without consent, accountability and rights as insufficient. Feminist perspectives explore how coercion and insecurity affect groups differently. Postcolonial perspectives question whether external judgments use standards selectively or maintain unequal global power relationships.

Myanmar after the 2021 coup

The Myanmar military coup of 2021 removed the elected civilian government, triggering mass resistance, armed conflict and civil disobedience. By using lethal force and repression, the junta weakened its claim to popular consent. Its limited ability to govern contested territory also challenged its performance-based legitimacy.

External stakeholders disputed the junta’s standing as well. The Association of Southeast Asian Nations restricted Myanmar’s representation at high-level meetings, while several governments imposed sanctions. Yet the military retained coercive capacity, showing that control over state institutions is not the same as recognized rightful authority.

Haiti’s governance crisis, 2021–2024

After the assassination of President Jovenel Moïse in 2021, Haiti faced deepening political instability and expanding armed-group control. The failure to provide security, welfare and consistent administration weakened confidence in both the government and the state’s capacity.

Supported by regional and international diplomacy, the creation of Haiti’s Transitional Presidential Council in 2024 aimed to restore a basis for governing authority. External involvement alone, however, could not create domestic legitimacy. That depended on effective administration, broader representation and improved security for citizens.

Non-state actor legitimacy is the recognition that an actor outside a state’s formal institutions has an appropriate role in influencing politics or pursuing political goals. That recognition may come from governments, communities, supporters, international organizations or other non-state actors. Different audiences may reach different judgments.

Four bases of legitimacy

These sources often overlap. Technical ability and successful delivery can build legitimacy without elections, though weak representation may still attract criticism. Recognition from governments can provide access to decision-making. Where the government itself lacks trust, however, recognition from communities may carry more weight.

Liberals often regard civil-society groups and international organizations as legitimate participants when they strengthen cooperation, accountability or service provision. Realists are more cautious when non-state influence competes with state authority. Constructivists examine how expertise, identity and accepted norms create authority. Feminist and postcolonial approaches ask whether organizations allow affected communities to set priorities or simply reproduce elite and externally imposed agendas.

The International Committee of the Red Cross in Ukraine, 2022

After Russia’s full-scale invasion of Ukraine in 2022, the International Committee of the Red Cross (ICRC) gained legitimacy from its humanitarian mandate, specialist knowledge and interaction with parties to the conflict. It could deliver assistance and seek access to prisoners, giving it influence without sovereign power.

Yet its legitimacy was contested. Ukrainian officials and families criticized the organization’s access to prisoners of war and people held in Russian-controlled areas. Formal recognition and expertise, then, don’t guarantee efficacy in every setting. Limited outcomes can weaken confidence among affected audiences.

Brazil’s Landless Workers’ Movement in 2023

Brazil’s Landless Workers’ Movement (MST) continued its campaigns for land reform and rural development in 2023. It claimed legitimacy by representing landless rural families. Through organized membership, public mobilization and agricultural cooperatives, the movement gained the ability to put land ownership and inequality on the political agenda.

Supporters point to the movement’s settlements and food production as evidence of efficacy and social representation. Opponents, including some landowners and conservative legislators, challenge its tactics and argue that occupations violate lawful property rights. A non-state actor may therefore be legitimate to one audience but illegitimate to another.

Legitimation is the process by which a political actor gains or strengthens recognition of its right to exercise authority or influence. Delegitimation occurs when that recognition is weakened or withdrawn.

Legitimacy isn’t a permanent possession. It is relational and can change as actions, interactions and outcomes shape the judgments of governments, citizens, international institutions, social movements and other audiences.

Main processes

• Formal top-down recognition: an actor with established authority grants status through accreditation, legal registration, diplomatic recognition, membership or another official procedure.
• Self-legitimation: an actor portrays its own authority as justified. It may draw on elections, law, ideology, identity, history, performance, public ceremonies or claimed achievements.
• Organic recognition: stakeholders accept an actor through direct experience, shared identity, trusted relationships or successful outcomes, rather than because recognition has been formally imposed.
• Legitimation and delegitimation by rivals: opposing actors promote or challenge claims to authority using political narratives, protest, exposure of abuses, legal challenges, sanctions or competing institutions.

Top-down and bottom-up recognition do not always match. A government may formally authorize an organization that communities distrust. By contrast, a popular movement may gain organic legitimacy without legal recognition. Self-legitimation also works only if the relevant audiences find the actor’s claims credible.

Constructivists stress how political language, symbols and shared expectations shape these changing judgments. Liberals emphasize lawful recognition, consent and accountable performance. Realists focus instead on whether recognition follows effective control and strategic interest. Feminist and postcolonial perspectives ask whose recognition counts as authoritative and whether formal processes exclude marginalized voices.

Afghanistan after the Taliban takeover in 2021

After taking control of Afghanistan in 2021, the Taliban pursued self-legitimation through military victory, religious authority and claims that it could restore order. Control of government institutions gave it practical power. However, most governments withheld formal recognition, showing that control does not automatically produce international legitimacy.

Restrictions on women’s education and participation led to delegitimation by Afghan activists, human rights organizations and international institutions. Some local acceptance may develop through security, identity or practical dealings. Even so, legitimacy remains divided among audiences and can shift with policy and performance.

Niger and ECOWAS in 2023–2024

Following Niger’s 2023 military coup, the junta sought self-legitimation through nationalist claims and public opposition to foreign influence. Supportive demonstrations provided some organic recognition. Opponents, however, argued that removing an elected president had destroyed constitutional legitimacy.

The Economic Community of West African States (ECOWAS) suspended Niger and imposed sanctions, using top-down delegitimation against unconstitutional rule. Niger’s announced withdrawal from ECOWAS in 2024, alongside Mali and Burkina Faso, also served as a rival strategy. The military-led governments challenged ECOWAS’s authority while promoting an alternative regional alignment, showing how political actors can legitimize themselves while delegitimizing others.
