3.9 - Challenges from Political and Social Cleavages
Multinational states, countries containing multiple ethnic, religious, or national groups, face distinct challenges maintaining political stability. These cleavages create tensions governments must manage carefully to avoid instability, violence, or outright state breakdown.
Challenge 1: Conflicting Interests and Competition Among Groups
Cleavages create competing interests that make unified policy-making difficult and turn political competition into a contest between groups rather than a debate over ideas.
Groups compete over resource distribution: which regions get infrastructure investment, how revenue from natural resources gets shared, and who bears the environmental costs. Nigeria's oil wealth creates intense conflict between the producing Niger Delta region, which demands a bigger share through "resource control" or "derivation" formulas, and northern states that resist redistribution reducing their own federal allocations. China's development resources flow mostly to coastal Han-majority regions, leaving Uyghurs and Tibetans resentful that Han Chinese benefit disproportionately from development in their own territories.
Groups also compete over land and territory: Nigeria's herder-farmer conflicts pit predominantly Muslim Fulani herders against predominantly Christian farmers over scarce land, intensified by climate change and population growth, and Northern Ireland's disputes over parade routes reflect ongoing Protestant-Catholic competition for symbolic control of space.
Political power itself becomes a competition: Nigeria's presidency involves explicit ethnic calculations with informal rotation between North and South, and when one region holds it, others feel excluded. Iran's Persian-dominated government creates similar tension with Azerbaijani, Kurdish, and Arab minorities who feel shut out of real power.
Policy preferences also conflict along cleavage lines: religious law implementation (Nigeria's Sharia states conflicting with southern Christian preference for secular law), language policy (China's Mandarin-only education conflicting with Uyghur and Tibetan desire for mother-tongue education, seen by minorities as a cultural survival issue), and cultural and social policy (Iran's mandatory hijab laws conflicting with secular and minority women's preferences).
Political parties often organize explicitly around these cleavages rather than ideology, turning elections into what's essentially an ethnic census. Nigerian parties, despite claiming national character, have clear ethnic-regional bases, and Northern Ireland's party system divides cleanly along Protestant-Catholic lines (DUP and UUP versus Sinn Féin and SDLP), making cross-sectarian cooperation genuinely difficult.
All of this creates real challenges: policy paralysis when groups can't agree on distribution, political instability when elections become high-stakes ethnic competitions with winners monopolizing power, a zero-sum mentality that makes compromise hard to reach, and a kind of "resource curse" in diverse societies where valuable resources actually intensify distributional conflict rather than benefiting everyone.
Challenge 2: Perceived Lack of Governmental Authority and Legitimacy
Cleavages can undermine legitimacy directly when groups view the government as illegitimate or lacking real authority over them.
Ethnic or national minorities sometimes view government as a foreign or colonial imposition, especially where states were created by colonialism or conquest with borders imposed without consent. Uyghurs and Tibetans often view Chinese rule as colonial occupation of territories that were once independent, meaning the government can really only rule through repression since voluntary compliance is largely absent. Chechens similarly view Russian rule as a colonial legacy going back to Russia's conquest of the Caucasus in the 1800s and Stalin's mass deportation of the Chechen people to Central Asia in 1944.
When one ethnic, religious, or regional group monopolizes power, minorities can come to see the government as belonging to that group rather than to the nation as a whole, undermining legitimacy and requiring coercion rather than consent to maintain compliance. Iran's Persian Shi'a domination delegitimizes the regime among ethnic minorities like Kurds, Arabs, and Baloch (most Kurds and Baloch are Sunni), who see the Islamic Republic as a Persian Shi'a state that doesn't represent them.
Systematic discrimination, economic marginalization, political exclusion, and cultural suppression (banned languages, restricted religious practice, denied identity) all compound this legitimacy problem. China's suppression of Uyghur language, culture, and religion, including detention camps and mass surveillance, has left many Uyghurs viewing the state purely as an oppressor rather than a legitimate authority.
Government weakness in providing security and basic services in minority regions further undermines authority: Nigeria's long inability to defeat Boko Haram in the northeast undermines federal legitimacy, since citizens question the authority of a government that can't provide basic security, and Mexico's inability to control cartel violence in some regions similarly undermines the state's fundamental claim to authority.
And groups sometimes question the constitutional basis of the state itself, pointing to gaps between formal promises and reality: Russia's constitution formally promises federalism and minority rights, but the actual practice of centralized authoritarianism suppressing minorities delegitimizes the regime among those who see the promised rights as hollow.
These legitimacy deficits create real consequences: governments end up relying on coercion rather than consent, which is expensive and unstable; minorities engage in civil disobedience or build parallel institutions; separatist movements emerge as groups seek to escape what they see as illegitimate rule; and international actors sometimes exploit the legitimacy weakness, as with the Dalai Lama's exile appeals against Chinese rule in Tibet.
Challenge 3: Pressure for Autonomy or Secession, Intergroup Conflict, Terrorism, and Civil War
Deep cleavages can escalate to genuinely violent challenges threatening state survival.
Autonomy movements seek self-governance short of full independence, typically wanting control over education, language, and culture along with local governance authority while still maintaining a connection to the larger state. The UK's devolution to Scotland, Wales, and Northern Ireland responded to exactly this kind of pressure, though it's also created new challenges, like continued Scottish demands for more powers and repeated collapses of Northern Ireland's power-sharing government.
Secessionist movements go further, seeking complete independence, usually motivated by a belief that independence is the only way to protect the group, combined with historical memories of independence or a belief that the group constitutes a genuinely distinct nation. The Chechen independence movement fought two devastating wars (1994-96, 1999-2009), since Russia saw Chechen secession as an existential threat that could unravel the whole federation if other regions followed suit, and tens of thousands died as a result. Nigeria's Biafran secession attempt in 1967 triggered a civil war that killed over a million people, and while the federal government militarily defeated Biafra, separatist sentiment persists today through the IPOB movement. Scotland's 2014 referendum came close (45% for independence) but stayed within the union, showing that secession pressure can sometimes be resolved democratically rather than through violence.
Intergroup conflict and violence involves ethnic riots, religious violence, and communal clashes that can spiral out of control. Nigeria experiences repeated Christian-Muslim clashes and herder-farmer conflicts with ethnic-religious dimensions, and Northern Ireland's "Troubles" (1968-1998) killed over 3,500 people before the Good Friday Agreement finally brought partial resolution. China's 2009 Urumqi riots between Uyghurs and Han Chinese killed 197 people by the official count (Uyghur groups say more), showing how quickly intergroup tension can turn violent.
Terrorism, systematic violence against civilians for political goals, often emerges directly from these cleavages. Boko Haram's insurgency in northeastern Nigeria, rooted in religious cleavage and northern marginalization, directly killed about 35,000 people by 2020 and has displaced millions; a 2021 UN Development Programme study estimated nearly 350,000 deaths in the northeast by the end of 2020 once hunger and disease caused by the conflict are counted, most of them young children. Chechen terrorism brought violence into the Russian heartland through attacks like the Moscow theater siege (2002) and the Beslan school massacre (2004). The UK experienced IRA terrorism throughout the Troubles, including the Brighton hotel bombing targeting Thatcher in 1984.
Civil war represents the most extreme escalation, where the state loses its monopoly on violence entirely. The Nigerian Civil War (1967-1970) killed between 1 and 3 million people, mostly from starvation, and traumatized the nation's politics for generations. The Russian Civil War (1918-1922) let various nationalities pursue independence or autonomy amid the broader ideological conflict. Iran's post-revolutionary period (1979 through the 1980s) saw ethnic insurgencies by Kurds, Arabs, Baloch, and Turkmen that came close to producing full civil war during the revolutionary chaos.
There's a recognizable escalation pattern here: peaceful autonomy demands lead to government rejection or repression, which leads to protests and civil disobedience, which can trigger government violence against protesters, which radicalizes opposition toward armed resistance, which can develop into terrorism and then organized insurgency, and finally full civil war. Chechnya followed roughly this path, and so did Biafra. The core challenge for governments is intervening early, through accommodation or addressing grievances, before violence becomes organized and self-sustaining, something that requires wisdom and flexibility many governments simply lack.
Several factors help explain why cleavages produce violence in the first place: a security dilemma where groups arm themselves defensively, prompting others to do the same in a spiral; historical grievances and revenge motivations passed down through generations; elite mobilization, where politicians exploit cleavages for their own political gain; and state weakness that leaves governments unable to mediate conflicts or enforce order.
Challenge 4: Encroachment of Neighboring States
Social cleavages create vulnerabilities that neighboring states can exploit through intervention, support for separatists, or outright territorial aggression.
When ethnic groups span international borders, cross-border ties can create real vulnerability. Kurds live across Turkey, Iraq, Iran, and Syria, and Kurdish separatism in one country can draw support from Kurdish populations in another. Russians living in former Soviet republics like Ukraine, the Baltic states, and Moldova have provided a pretext for Russian intervention, with Putin's regime claiming to protect ethnic Russians abroad; Ukraine's eastern regions with significant Russian populations became specific targets for Russian intervention and eventual invasion.
Neighboring states also sometimes directly support separatist movements to weaken a rival, gain strategic advantage, or protect ethnic kin, providing weapons, funding, or safe havens that make insurgencies much harder to defeat and internationalize what would otherwise be purely domestic conflicts. Various foreign powers, including France and Portugal, supplied weapons to Biafra during the Nigerian Civil War, turning an internal ethnic conflict into something closer to an international proxy war.
Ethnic violence can also provoke humanitarian intervention from the international community, which, while sometimes genuinely protective, also violates state sovereignty and can escalate rather than resolve conflicts. And neighboring states sometimes seize territory outright when a government is weakened by internal ethnic conflict, using ethnic kin or counter-terrorism as justification; Russia's 2014 seizure of Crimea and intervention in eastern Ukraine exploited exactly this kind of internal Ukrainian division between Ukrainian-speaking nationalists and Russian speakers, taking advantage of Ukraine's weakness during the Euromaidan revolution.
Ethnic conflicts also produce refugee flows that can destabilize entire regions: Nigeria's Boko Haram insurgency and communal conflicts have pushed refugees into Chad, Niger, and Cameroon, spreading instability well beyond Nigeria's own borders. And great powers sometimes compete by exploiting each other's internal divisions for geopolitical advantage, as with Western support for Uyghur rights putting external pressure on China, or Russia's use of ethnic Russian populations in neighboring states as tools of influence.
Outside powers can also frame a country's internal cleavages in their own terms. In October 2025, the United States designated Nigeria a "Country of Particular Concern" for religious freedom, saying Christians there were being targeted, and on December 25, 2025, US forces struck Islamic State camps in Sokoto State in coordination with Nigeria's military. Nigeria's government rejected the idea that the violence is mainly religious persecution, pointing out that militants kill both Muslims and Christians, which shows how foreign involvement can raise the stakes of a country's religious divisions.
This kind of external encroachment is particularly dangerous because it internationalizes what would otherwise be internal conflicts, prolongs conflicts by sustaining separatists who might otherwise be defeated, violates state sovereignty in ways that can undermine the broader international system, and creates real potential for escalation from local ethnic conflict into full regional or even great-power confrontation.
How These Challenges Reinforce Each Other
These four challenges aren't independent, they tend to feed into each other in a cycle: conflicting interests lead to perceived illegitimacy, which leads to separatism and violence, which invites external encroachment, which in turn intensifies the original conflicting interests. Nigeria illustrates this cycle: ethnic competition over resources leads different regions to view the federal government as illegitimate whenever the other region controls it, which fed the Biafran secession attempt and contemporary separatism, which in turn drew in external powers supporting separatists, intensifying ethnic competition further.
Successfully managing these challenges requires inclusive governance that addresses conflicting interests fairly, building legitimacy across all ethnic groups rather than favoring one, preventing escalation from autonomy demands into violence, and securing borders against external exploitation. When governments fail to address even one of these challenges, the others tend to intensify, potentially cascading toward state collapse.
Bottom line: cleavages in multinational states create four genuinely interconnected challenges: conflicting interests make governance difficult, perceived illegitimacy undermines authority, autonomy pressure can escalate all the way to terrorism and civil war, and internal divisions create vulnerabilities to external encroachment. How governments respond, through inclusive power-sharing, repression, accommodation, or simple failure to act, determines long-term stability. Mismanagement can lead to state breakdown, while successful navigation, though genuinely difficult, can build resilient multinational states or at least prevent violent conflict. The stakes are about as high as they get: civil war, separatism, and external intervention all threaten the survival of the state itself.
