What Hugh Thomas's history of the Spanish Civil War reveals about the politics of the United States and India today.
This summer, I finally found time to read Hugh Thomas's much-recommended The Spanish Civil War.
I follow the politics of three to four countries fairly closely. What struck me while reading was how familiar the political dynamics felt, not as history, but as description of what is unfolding now in the United States, India and elsewhere. That recognition is uncomfortable, and it is the reason the book is worth reading now rather than at leisure.
Much of Europe's political history since the French Revolution can help us understand developments elsewhere, though never as a perfect template. Similar combinations of economic stress, widening inequality, declining institutional legitimacy, elite fragmentation and identity-based mobilisation tend to produce comparable political pressures. The language changes. The technologies change. The institutions and local circumstances differ. The underlying contest, over power, resources, status, legitimacy and control of the state, remains remarkably persistent. History does not provide a script for the future. It provides a library of recurring structures, incentives and warning signs.
The Spanish Civil War did not emerge from a single dispute. Several unresolved conflicts between classes, regions, religions, ideologies and institutions, gradually fused into one existential struggle. Church confronted secular liberalism; landowners confronted workers and peasants; centralisation confronted regional autonomy. Civilian rule confronted military intervention; constitutional reform confronted revolution; democratic modernisation confronted authoritarian modernisation. The Second Republic attempted to address these tensions simultaneously, but its political ambition exceeded its administrative, fiscal and coercive capacity. Reform threatened those who expected to lose power and disappointed those who believed change was arriving too slowly. That is the worst of both outcomes, and it is more common in reforming governments than the reformers expect.
Once every political disagreement was interpreted as a battle for the survival of the nation, compromise began to look like betrayal. Opponents were no longer people with competing interests; they became enemies who had to be defeated. That is when politics stopped functioning as a mechanism for managing conflict and became a vehicle for escalating it. Unresolved divisions produced ambitious reform. Reform generated resistance and frustrated expectations. Both sides radicalised. The political centre collapsed. Military rebellion fragmented state authority, and the conflict developed into an internationalised civil war.
No single step in that sequence was obviously irreversible while it was happening.
Democracy becomes fragile when election losers treat results as temporary and preserve insurrection or military intervention as alternative routes to power. Polarisation is interactive: each camp uses the other's extremists to justify its own, while violent minorities destroy the credibility of moderate majorities. The moderates are rarely defeated in argument. They are made irrelevant by people who never argued.
Constitutional legitimacy becomes meaningless when the state loses control over weapons, policing, prisons and local administration. Once competing parties, militias and regional organisations acquire independent coercive power, the state may remain legally recognised while ceasing to exercise practical sovereignty.
A constitution is a description of how power is meant to work, not a source of the power itself.
The war also shows why disciplined centralisers often defeat divided pluralist coalitions. The Nationalists broadly agreed on what had to be destroyed, while the Republicans disagreed over what should replace it; negative unity proved stronger than competing positive visions. Long wars reward organisations capable of taxation, conscription, procurement, intelligence, punishment and logistical coordination. Foreign aid matters less in total value than in timing, reliability and integration, while supposedly neutral rules can favour the side willing to violate them. Terror and political symbols serve as instruments of mobilisation and state-building while eliminating the possibility of compromise. The enduring lesson is not that every polarised society will reproduce Spain, but that institutional weakness can convert disagreement into insecurity, insecurity into existential hostility, and political conflict into a struggle in which coercion appears more credible than constitutional compromise.
What travels most directly from Spain to contemporary politics is the gradual transformation of ordinary disagreement into a struggle over national identity and survival. In Spain, both Left and Right claimed to represent the "real Spain." Comparable conflicts are visible today in India and the United States. Hindu-civilisational nationalism competes with a secular, plural and federal conception of India, while nationalist and Christian-conservative ideas of America confront a liberal, multicultural and institution-centred vision. Religion, history, immigration, language, race, education and citizenship become fused into a single identity conflict. Political opponents are no longer regarded merely as mistaken but as anti-national, authoritarian, fascist, communist or fundamentally illegitimate. Once each side believes that the other's control of government threatens the survival of the nation, compromise begins to resemble surrender and every election is presented as the final opportunity to save the country. An election that is genuinely the last one is a description of a system that has already failed.
Polarisation then becomes self-reinforcing in ways that would be familiar to any observer of 1930s Spain, though the mechanism has changed. Each camp uses the other's most extreme voices to justify its own radicalisation: inflammatory rhetoric produces countermobilisation, retaliation confirms the original fear, and fringe behaviour comes to define entire political communities. Algorithmic media accelerates this by creating separate realities in which each side contextualises its own excesses, generalises those of its opponents and interprets correction as censorship.
Confidence in supposedly neutral institutions declines at the same time. Courts, election authorities, investigative agencies, police, universities and the media are judged less by the legality of their decisions than by the political camp believed to control them. Economic grievances involving employment, education, housing, agricultural income and inequality are absorbed into conflicts over religion, caste, immigration, race and national identity. This is the more consequential substitution: material problems have negotiable solutions, identity conflicts do not. Moderate politics loses emotional force. Procedure and gradual reform struggle to compete with the certainty, belonging, enemies and promises of national rebirth offered by more radical movements.
Here the comparison meets its limit, and it is worth being precise about where, because imprecise historical analogy is itself a form of the problem being described.
Spain's collapse was a collapse of the state's monopoly on coercion. Parties, unions and regional movements built and armed their own militias, and by July 1936 the government could no longer guarantee that its writ ran anywhere in particular. Nothing resembling that exists in India or the United States today. Both retain functioning elections, civilian control of the military, opposition governments, courts and legislatures, and an unchallenged state monopoly over organised military force. The polarisation described above is real, but it is a polarisation of narrative, trust and institutional perception, not of armed capacity. That distinction matters more than any other in this comparison: identity conflict can corrode a democracy for a long time without producing the coercive fragmentation that turned Spain's political crisis into a civil war.
The risks that remain are different in each country. India's principal danger is the consolidation of a majoritarian political project that increasingly claims privileged ownership of national identity, benefits from opposition fragmentation, and places the neutrality of institutions under strain. America's greater danger is reciprocal delegitimation between two relatively balanced political blocs, accompanied by disputes over electoral legitimacy and growing tolerance for executive exceptionalism.
Civil war is not the lesson to take from Spain. The earlier and more useful one is this: political breakdown begins long before anyone reaches for a weapon — when opponents cease to be legitimate, institutions cease to be trusted as neutral, electoral defeat becomes intolerable, and every separate dispute is incorporated into one existential struggle over who truly belongs to the nation.
By the time the weapons appear, the argument that made them possible has already been won.
