Key facts and dates

Political factors within a country often play a critical role in sparking both civil and international wars, as internal struggles for power, instability, and ideological clashes create conditions ripe for conflict. This timeline captures key events and periods where domestic politics directly contributed to war.

Timeline of key events

• 1917-1922 – Russian Civil War follows the Bolshevik Revolution under Lenin.
• 1936-1939 – Spanish Civil War emerges from the collapse of the Second Republic and polarisation; Franco led the Nationalist forces.
• 1962-1970 – North Yemen Civil War breaks out after a republican coup against the Imam.
• 1967-1970 – Nigerian Civil War results from ethnic tensions and political instability post-independence, led by Ojukwu.

• 1990s – Balkan Wars follow the collapse of Yugoslavia after Tito's death, influenced by leaders like Milošević.

Domestic political instability and revolutions as causes of war

Political instability within a nation often creates a breeding ground for conflict, as power vacuums, revolutionary movements, and social unrest can escalate into full-scale wars. When governments lose legitimacy or fail to address deep-seated grievances, revolutions can erupt, drawing in various factions and sometimes foreign powers.

Key examples of instability and revolutionary conflict

• Mexican Revolution (1910-1920) - This conflict arose from widespread discontent with the long-standing dictatorship of Porfirio Díaz, whose regime was marked by inequality and repression. Revolutionary groups sought land reform and political change, leading to a decade of violence as factions fought for control.
• Russian Civil War (1917-1922) - Following the Bolshevik Revolution led by Vladimir Lenin, this war pitted the communist Red Army against various anti-communist White forces, including monarchists and foreign-backed groups. The revolution destabilised the country, creating chaos that fuelled a brutal internal conflict.
• Spanish Civil War (1936-1939) - Emerging from the failure of the Second Republic, this war resulted from deep political polarisation between left-wing republicans and right-wing nationalists, led by Francisco Franco. The breakdown of consensus and ideological extremism turned domestic disputes into a violent struggle with international involvement.

Why revolutions lead to war

• Power vacuums - Overthrowing a regime often leaves a gap in authority, inviting competing groups to fight for dominance.
• Ideological divides - Revolutions frequently pit opposing ideologies against each other, as seen in Russia and Spain, intensifying conflict.
• Foreign intervention - Revolutionary upheaval can attract outside powers supporting different sides, prolonging and escalating the fighting.

The impact of weak or failing governments on conflict

When governments are unable to maintain control or address internal divisions, the resulting weakness can lead to civil wars or regional conflicts. Failing states often struggle with legitimacy, economic collapse, or ethnic tensions, creating conditions where violence becomes a means to resolve disputes.

Examples of conflicts driven by governmental weakness

• Nigerian Civil War (1967-1970) - Following independence from Britain, Nigeria faced severe political instability due to ethnic tensions between the Igbo, Hausa, and Yoruba groups. The secession of Biafra, led by Odumegwu Ojukwu, was a direct result of a weak central government failing to manage these divisions, leading to a devastating war.
• Balkan Wars (1990s) - The collapse of Yugoslavia after the death of Josip Broz Tito left a fragmented region with weak successor states. Ethnic rivalries and nationalist leaders, such as Slobodan Milošević, exploited this power vacuum, resulting in a series of brutal conflicts across Bosnia, Croatia, and Kosovo.

Consequences of governmental failure

• Loss of authority - Weak governments cannot enforce laws or maintain order, allowing armed groups to challenge the state.
• Ethnic and regional divisions - Without strong central control, longstanding tensions often surface, as seen in Nigeria and the Balkans.
• Opportunity for warlords and militias - Failing states create spaces for non-state actors to gain power through violence, further destabilising the region.

Leaders using external wars to consolidate domestic power

Some leaders initiate or escalate external conflicts as a strategy to unify their country, distract from internal problems, or strengthen their own position. By focusing attention on an outside enemy, they can rally national support and suppress dissent at home.

Notable cases of external conflict as a political tool

• Falklands/Malvinas War (1982) - Argentine leader Leopoldo Galtieri launched the invasion of the Falkland Islands to divert public attention from a severe economic crisis and widespread political repression under his military junta. This gamble aimed to boost national pride but ultimately failed when Argentina lost the war to Britain.
• Iran-Iraq War (1980-1988) - Saddam Hussein, having recently seized power in Iraq, invaded Iran partly to consolidate his regime. By portraying Iran as a threat, he sought to unify Iraqis under his leadership and suppress internal opposition, though the prolonged war drained resources and deepened domestic issues.

Mechanisms and risks of this strategy

• Nationalist fervour - External wars can temporarily unite a population through patriotism, masking domestic failures.
• Distraction from crises - Focusing on an outside enemy shifts public scrutiny away from economic or political problems.
• High stakes - Failure in war, as with Galtieri, can backfire, leading to greater unrest or loss of power for the leader.

Succession crises and coups as triggers for civil wars

Sudden changes in leadership, especially through coups or disputed successions, can destabilise a country and lead to civil conflict. These events often fracture political systems, creating rival factions that resort to violence to secure control.

North Yemen Civil War (1962-1970)

This war began after a republican coup overthrew the monarchy of Imam Muhammad al-Badr. The ensuing power struggle between republican forces, supported by Egypt, and royalist factions, backed by Saudi Arabia, turned a domestic succession crisis into a prolonged civil war with regional dimensions.

Why succession crises lead to war

• Legitimacy disputes - Coups and abrupt changes often lack broad support, leading to challenges from ousted groups or rival claimants.
• Factional splits - Political elites and military forces may align with different sides, as in Yemen, escalating tensions into armed conflict.
• External involvement - Regional powers often intervene to support preferred factions, turning internal crises into proxy wars.

The role of political extremism and failed reforms in sparking conflict

Political extremism, where radical ideologies dominate, and the failure of reforms to address systemic issues can both drive societies towards war. When consensus breaks down and moderate solutions are rejected, violence often becomes the default method to achieve political aims.

Patterns of extremism and reform failure

• Ideological extremism - Extremist ideologies, whether communist, fascist, or nationalist, reject compromise and polarise societies, as seen with Franco in Spain or Lenin in Russia. This unwillingness to negotiate fuels internal divisions that erupt into war.
• Failed reforms - When governments attempt reforms but fail to deliver meaningful change, public frustration grows. In Mexico under Díaz, promised reforms were undermined by corruption and elitism, driving revolutionary movements.
• Breakdown of consensus - The inability to maintain political agreement, as in the Spanish Second Republic, allows extremist factions to gain traction, replacing dialogue with conflict.

Long-term effects on conflict

• Radicalisation of politics - Extremism hardens positions, making peaceful resolutions unlikely and war almost inevitable.
• Cycle of unrest - Failed reforms discredit governments, leading to repeated uprisings or coups, perpetuating instability.
• Attraction of violence - When political systems fail to accommodate diverse views, groups turn to armed struggle to enforce their vision, deepening societal fractures.
