Few political concepts carry as much weight as revolution. The word brings to mind the storming of the Bastille, the execution of a king, or the rise of an entirely new social order from the ashes of the old. A revolution is not just another change of government. It is a rapid, fundamental transformation of a society’s class, state, or political structures, almost always carried out through widespread violence and powered by deep ideological commitment. Understanding why revolutions happen, how they unfold, and why violence so often sits at their core is one of the most important questions in political theory. This post unpacks the meaning of revolution, traces its modern history, and examines the major theories that explain it.

What makes a revolution different
Not every uprising is a revolution. A coup simply replaces one set of rulers with another. A riot expresses anger but rarely reshapes institutions. A revolution aims much higher. According to political scientist Jack Goldstone, a revolution is an effort to transform political institutions and the very justifications for political authority, carried out through mass mobilisation and actions that fall outside normal political channels.
This definition tells us two things. First, revolutions target the foundations of power, not just the people holding it. Second, they require ordinary people to act in large numbers and often outside the law. Samuel Huntington described revolution as a rapid and violent change in values, social structure, political institutions, and leadership. The scale of ambition is what sets revolution apart from lesser forms of conflict.
Scholars also draw a distinction between political and social revolution. A political revolution changes who rules and how authority is justified. A social revolution goes further, transforming the deep structures of society itself, including class relations and the economy. Theda Skocpol’s influential work treats social revolution as the far rarer phenomenon that reshapes both state institutions and societal relations.
Why revolution is a modern phenomenon
It may seem like revolutions have always existed, but most scholars argue otherwise. Political conflict is as old as humanity, yet the idea of radically transforming an entire society only became possible with the rise of the modern state. Once states developed the administrative reach to govern large populations, revolution became both possible and, for many people, desirable. The modern state system that originated in Europe and spread across the globe created the very target that revolutionaries seek to capture and remake.
Modern revolutions that reshaped the world
The great revolutions of the seventeenth and eighteenth centuries set the template for everything that followed. Each one challenged existing power and left behind new political and class arrangements.
The English Civil War
The English Civil War of the 1640s pitted Parliament against the Crown and ended with the execution of King Charles I in 1649. For a brief period England became a republic. While the monarchy was later restored, the conflict permanently shifted the balance of power away from absolute kingship and towards parliamentary authority. It demonstrated that even a divinely sanctioned monarch could be held accountable, and ultimately removed, by force.
The American Revolution
The American Revolution of 1776 broke thirteen colonies away from British rule and produced a new republic founded on the principles of popular sovereignty and representative government. Its significance lay not only in independence but in the claim that legitimate authority flows from the consent of the governed. This idea would echo through revolutionary movements for centuries.
The French Revolution
The French Revolution of 1789 is the event that most defines our modern understanding of revolution. It overthrew the monarchy, abolished feudal privileges, and attempted to reconstruct society around the ideals of liberty, equality, and fraternity. It also revealed the darker face of revolution through the Reign of Terror. For many later thinkers, the French Revolution raised a profound question about how a society should be held together once the old hierarchies were destroyed. Some revolutionaries came to see violence itself as a means of social regeneration, a way to forge a new sovereign people out of the wreckage of the old order.
Why violence sits at the heart of revolution
Violence is not an accidental feature of revolution. Many social scientists view it as an essential characteristic. The reason is structural. States hold a monopoly on the legitimate use of force, and those in power rarely surrender it voluntarily. When a movement seeks to overturn the entire system, the state will defend itself, and confrontation becomes almost inevitable.
This is why a revolution is sometimes described as a violent transference of power and property, a seizure of authority and a redistribution of wealth. The deeper the transformation a movement seeks, the more resistance it provokes, and the more force it tends to require. Some philosophers have argued that violence can function as an acceptable means of achieving material liberty and equality rather than merely formal, legal equality. Their argument is that genuine change must reach the concrete conditions of society, such as the relations of production, and cannot be satisfied by abstract political principles alone.
Theories that explain why revolutions happen
Why do revolutions break out when they do? Three influential theorists offer very different answers, focusing on psychology, social systems, and economic class.
Ted Robert Gurr and relative deprivation
In his 1970 classic Why Men Rebel, Ted Robert Gurr argued that political violence grows out of frustration. His central concept is relative deprivation, which he defined as the discrepancy between what people believe they deserve and what they think they can actually get. The key insight is that deprivation is relative, not absolute. People do not necessarily rebel because they are poor or starving. They can become resigned to even terrible conditions.
Rebellion becomes likely when a gap opens between expectations and reality, between what people feel entitled to and what they are able to achieve. Gurr’s hypothesis was that the potential for collective violence varies strongly with the intensity and scope of relative deprivation within a population. He built this on the frustration-aggression mechanism: when frustration is prolonged and sharply felt, it often hardens into anger and eventually violence.
Importantly, Gurr’s full model goes beyond grievance alone. As he later explained, understanding rebellion requires examining three factors: popular discontent, people’s beliefs about the justifiability of political action, and the balance between citizens’ capacity to organise and the government’s capacity to repress them. Grievance provides the fuel, but ideology and organisation determine whether it ignites.
Chalmers Johnson and the disequilibrated society
Chalmers Johnson approached revolution from a systems perspective in his 1966 book Revolutionary Change. He viewed society as a social system that normally maintains a state of balance, or equilibrium, in which shared values and social structures stay synchronised with one another. Revolution, for Johnson, is what happens when that balance breaks down.
When rapid change, whether economic, technological, or external, causes values and social reality to fall out of step, the system enters disequilibrium. Johnson described this as a desynchronised social condition. If the existing authorities fail to resynchronise the system through reform, and instead resort to force to hold things together, they suffer a loss of legitimacy. At this point, the conditions for revolution are present. Johnson’s case study of the Vietnamese Revolution illustrated how disruptive change created a desynchronised situation that spurred a movement which became a violent revolution. He also stressed the decisive role of military power in determining a revolution’s outcome.
Karl Marx and class struggle
No discussion of revolution is complete without Karl Marx. For Marx, revolution is the engine of historical progress, driven by economic conflict between classes. His starting point is the famous claim that the history of all hitherto existing societies is the history of class struggles. Society, in his analysis, splits into two opposed classes: the bourgeoisie, who own the means of production, and the proletariat, who own only their labour.
Marx drew on the Hegelian dialectic, in which the conflict between a dominant group and a subordinate group produces a new social order. He believed history moves through progressive stages, each ending when the dominant class is overthrown. According to Marx and Engels, the French Revolution marked the overthrow of the aristocracy by the bourgeoisie, who then built capitalism on the ruins of feudalism. This, in turn, created the industrial proletariat, the class destined to overthrow the bourgeoisie and establish a classless communist society.
For Marx, then, revolution was not a tragic accident but an inevitable outcome of capitalism’s internal contradictions. He argued that the bourgeoisie produces its own grave-diggers, making the fall of the bourgeoisie and the victory of the proletariat equally inevitable. Violence, in this framework, is the means by which one mode of production gives way to the next.
Comparing the three approaches
These theories are best understood as complementary lenses rather than rivals. Gurr focuses on the psychological dimension, explaining the discontent that pushes individuals towards rebellion. Johnson offers a sociological and systemic view, explaining how an entire society loses its balance and legitimacy. Marx provides an economic and structural account, locating the root cause in class conflict and the ownership of production.
Together they capture the layered reality of revolution. A revolution needs aggrieved people, a destabilised social system, and underlying structural tensions, all combined with a guiding ideology that convinces participants their cause is just and their violence justified. The German philosopher Hegel, whose ideas shaped Marx, even saw revolutions as the fulfilment of human destiny, with revolutionary leaders necessary to instigate and implement deep reform.
The legacy of revolutionary violence
The transformative power of revolution cuts both ways. Revolutions have toppled monarchies, ended feudal privilege, and spread ideas of popular sovereignty and equality across the globe. Yet the violence that makes them possible can also consume them. The French Revolution’s Reign of Terror and the brutal phases of later revolutions remind us that the same force used to dismantle an unjust order can be turned against citizens by the new rulers themselves. Understanding revolution means holding both truths together: it is a source of profound human liberation and a process that frequently extracts a terrible human cost.
What do you think? If relative deprivation, systemic disequilibrium, and class conflict are all present in a society, what determines whether change comes through peaceful reform rather than violent revolution? And in an age of mass communication and global connection, do the classic theories of revolution still explain the political upheavals we see today?
