Getting Started

Political Stability refers to the ability of a state and its regime to maintain authority, legitimacy, and the rule of law in the face of internal challenges. This chapter compares how internal actors—from citizen protest groups to violent separatists—interact with state authority across the six course countries. Understanding these interactions helps explain why some regimes endure while others face crises, and how citizen pressure can lead to either repression or meaningful political reform.

What You Should Be able to Do

  • Explain how different internal actors, such as protest movements or separatist groups, can either support or threaten state stability.

  • Compare state responses to challenges like corruption, separatism, and mass protests in countries such as Iran, Mexico, and Nigeria.

  • Explain the connection between a state's response to internal threats and its economic goals, such as attracting foreign investment.

  • Analyze how pressure from civil society can lead to political reforms that enhance transparency, fairness, and civil liberties.

Key Developments & Analysis

The primary challenge to political stability comes from internal actors who question or defy state authority. A regime's response to these challenges is a critical indicator of its type, capacity, and durability. We can compare these responses across different regime types and contexts.

Theme/DimensionUnited KingdomRussiaChina
Response to Mass ProtestsProtests are generally permitted as a civil liberty. State response is typically managed by police to maintain public order, not to eliminate dissent.Protests, especially those deemed anti-regime, are heavily restricted. State response often involves mass arrests, legal prosecution of organizers, and police force.Unauthorized protests are strictly forbidden and met with overwhelming state force and surveillance. The state aims to prevent mobilization before it begins.
Response to SeparatismThe state has largely responded to separatist demands (e.g., in Scotland and Northern Ireland) through political channels, including devolution and referendums.The state has used overwhelming military force to crush violent separatist movements (e.g., in Chechnya) and suppresses regional autonomy movements that challenge central authority.The state uses a combination of economic development, coercive security measures, and forced assimilation to suppress separatist movements among ethnic minorities (e.g., Uyghurs, Tibetans).
Why This MattersDemocratic regimes provide institutional channels for dissent and regional demands, which can enhance long-term stability by managing conflict. Authoritarian regimes prioritize absolute control, viewing protest and separatism as existential threats to be eliminated, often creating deeper, unaddressed grievances.
Theme/DimensionIranMexicoNigeria
Response to Internal ViolenceThe state uses specialized security forces (e.g., Revolutionary Guard, Basij) to violently suppress protests (e.g., Green Movement) and ethnic separatist groups.The state has struggled to contain violence from powerful drug trafficking organizations, with responses varying from direct military confrontation to accommodationist policies.The state is engaged in a long-term military conflict against the violent separatist group Boko Haram in the northeast, while also facing widespread banditry and inter-communal violence.
Response to DiscriminationThe regime enforces gender discrimination through law (e.g., compulsory hijab) and systematically discriminates against religious and ethnic minorities, viewing related protests as threats to the state's identity.While legal protections exist, the state has been slow and often ineffective in addressing violence against women and discrimination against indigenous communities, often due to corruption and weak rule of law.The state officially prohibits discrimination, but deep ethnic and religious divisions fuel conflict and inequality, which the government struggles to manage, often exacerbating instability.
Why This MattersIn these countries, the state's monopoly on legitimate violence is directly challenged by powerful non-state actors. The state's response—whether through coercion, ineffective policy, or prolonged conflict—directly impacts its stability, rule of law, and ability to protect its citizens.

Challenges in Hybrid and Developing States

ChallengeMexicoNigeriaIran
Political CorruptionPervasive; weakens police and judicial institutions, fueling public distrust and enabling drug cartels.Systemic; diverts state resources, undermines rule of law, and is a major grievance driving protests like #EndSARS.Widespread within state and parastatal organizations (e.g., bonyads), undermining economic performance and regime legitimacy.
Separatist ViolencePrimarily from indigenous rights groups like the Zapatistas (EZLN), though largely dormant now.A major threat from groups like Boko Haram and Biafran secessionists, challenging the state's territorial integrity.The state actively suppresses ethnic separatist movements among Kurds, Arabs, and Baluchis.
Drug TraffickingA primary threat to state stability, with powerful cartels challenging state authority and corrupting institutions.A significant issue, but less of an existential threat to the state compared to separatism and corruption.A transit country for narcotics, but not a central challenge to regime stability on the scale of Mexico.

Challenges in Authoritarian and Democratic States

ChallengeUnited KingdomRussiaChina
Political CorruptionPresent but addressed through an independent judiciary, free press, and transparency laws. Scandals can force resignations.Systemic and centralized; used by the regime to reward loyalty and control elites. Anti-corruption campaigns are often used to eliminate political rivals.Pervasive, but the CCP uses large-scale anti-corruption campaigns to enforce party discipline, punish rivals, and bolster its legitimacy.
Mass ProtestsA regular feature of politics and a protected right.Tightly controlled; unauthorized protests are suppressed, and organizers are targeted by the state.Extremely rare and localized due to state surveillance and repression. Any large-scale dissent is seen as a major threat.

Institution–Actor–Function Map

This map shows how actors and institutions interact to produce outcomes related to stability.

Internal Actor(s)Key State Institution(s)Function / InteractionPotential Outcome for Stability
Citizen Protest Groups (e.g., #EndSARS, Green Movement)Security Forces (Police, Military, Revolutionary Guard); JudiciaryState responds with either coercion (arrests, violence) to suppress dissent or accommodation (policy reform, new laws).Threatened if coercion creates martyrs and deepens grievances. Enhanced if reforms address citizen demands and improve rule of law.
Separatist Groups (e.g., Boko Haram, Chechen rebels)Military; Central GovernmentState engages in armed conflict to preserve territorial integrity and defeat violent actors.Threatened by loss of territory, high costs of conflict, and erosion of state legitimacy. Enhanced if the state successfully restores order.
Civil Society Organizations (CSOs) focused on corruptionLegislature; Anti-Corruption Commissions; MediaCSOs pressure the state for greater transparency and accountability. The state may create new institutions or policies in response.Enhanced as reforms can increase transparency, attract foreign investment, and bolster public trust and the rule of law.

Country Anchors Bank

  • Green Movement (Iran): A 2009 mass protest movement against alleged election fraud. It represents a major internal challenge to the legitimacy of the Islamic Republic, which responded with brutal repression, demonstrating the regime's reliance on coercion to maintain stability.

  • Boko Haram (Nigeria): A violent Islamist separatist group in northeastern Nigeria. It serves as a powerful example of an internal actor that directly threatens state stability and territorial integrity through extreme violence, exposing the weakness of the Nigerian state's security apparatus.

  • Zapatista (EZLN) Uprising (Mexico): A separatist movement of indigenous peoples in Chiapas that challenged the state in the 1990s. It illustrates how a state may respond to such threats with a mix of military action and negotiation, and how such groups can pressure the state for greater recognition and rights.

  • #EndSARS Protests (Nigeria): A 2020 mass protest movement against police brutality. This is a key example of citizen pressure leading to promises of state reform, showing how civil society can push for policies that improve equality under law and limit state abuses.

  • Hong Kong Protests (China): Mass protests from 2019-2020 against perceived CCP encroachment on Hong Kong's autonomy. The state's response—imposing a sweeping National Security Law—is a clear example of an authoritarian regime using legal and coercive power to crush a protest movement and eliminate threats to its authority.

  • Good Friday Agreement (UK): The 1998 peace accord that ended decades of separatist violence in Northern Ireland. It is a prime example of a democratic state using negotiation, power-sharing, and devolution to resolve a violent internal conflict and enhance long-term stability.

  • Alexei Navalny's Anti-Corruption Protests (Russia): A series of protests organized by civil society to expose high-level corruption. The state's response—imprisoning Navalny and outlawing his organizations—shows how authoritarian regimes treat anti-corruption movements as direct threats to their power.

Skill Snapshots

Comparison

  • The UK managed separatist conflict in Northern Ireland through negotiation and devolution, while Russia used overwhelming military force to crush separatism in Chechnya.

  • In response to mass protests, China's regime preemptively suppresses dissent through surveillance and law, whereas Mexico's government must tolerate protests as a feature of its competitive political system.

  • Nigeria and Mexico both face powerful, violent non-state actors (Boko Haram and drug cartels), but the Nigerian state's challenge is primarily separatist and territorial, while Mexico's is a criminal challenge that deeply corrupts and co-opts state institutions.

Mechanism

  • State coercion (e.g., Iran's Revolutionary Guard suppressing the Green Movement) → elimination of immediate public dissent → short-term stability at the cost of unresolved public grievances and diminished legitimacy.

  • Citizen pressure from civil society (e.g., anti-corruption CSOs) → creation of new transparency policies → improved rule of law, which can attract foreign direct investment.

  • Pervasive corruption (e.g., in Nigeria's security sector) → weakens state capacity to fight insurgents → prolonged conflict and further erosion of political stability.

Change Over Time

  • Case: Nigeria

  • Baseline: Decades of military rule where stability was maintained through force and coups were the primary means of political change.

  • Changes: The 1999 transition to democracy introduced electoral competition but also opened space for new internal threats, such as the Boko Haram insurgency and mass protest movements like #EndSARS.

  • Continuity: The fundamental challenge of maintaining state stability and rule of law amid deep ethnic, religious, and regional divisions persists despite the shift in regime type.

Common Misconceptions & Clarifications

  • Misconception: Political stability means a country is peaceful and has no protests.

  • Clarification: Stable democracies often have frequent, peaceful protests, which are a sign of protected civil liberties. Instability refers to fundamental challenges to the state's authority or its ability to enforce the rule of law.

  • Misconception: All separatist movements are violent.

  • Clarification: Separatism exists on a spectrum, from peaceful political parties advocating for independence via referendum (e.g., in the UK) to violent insurgencies (e.g., in Nigeria).

  • Misconception: Authoritarian states are inherently more stable than democracies.

  • Clarification: Authoritarian regimes may appear stable by suppressing all dissent, but this can mask deep grievances that may erupt violently. Democracies have institutional channels like elections and protests to manage conflict and release political pressure.

  • Misconception: Corruption is only a major problem in less-developed countries.

  • Clarification: While often more systemic in states with weaker rule of law, corruption is present in all political systems. In established democracies like the UK, it typically manifests as political scandals that can erode public trust.

One-Paragraph Summary

Political stability depends on a state's ability to manage internal challenges to its authority and the rule of law. Internal actors, from civil society groups to violent separatists, constantly interact with the state, forcing a response that defines the regime. Democratic states like the UK tend to use negotiation and institutional channels to manage dissent, while authoritarian regimes like China and Iran rely on coercion and repression to eliminate threats. In countries like Mexico and Nigeria, the state's authority is directly contested by powerful violent actors, such as drug cartels and separatist groups, making stability precarious. States seek to limit the influence of these divisive actors to maintain order and attract economic investment, but pressure from citizen protests can also be a powerful force for positive reform, leading to improved transparency, civil liberties, and equality under law.
