Why the American Revolution Happened: Causes, Characters, Consequences

Introduction

The American Revolution did not begin as a campaign for national independence. It began as an argument inside an empire: a bitter, escalating dispute over who had the right to tax, legislate, command, and define liberty in a political world that stretched from London to Boston, from Caribbean sugar islands to Native homelands beyond the Appalachian Mountains. Only gradually did that argument become a war. Only gradually did the war become a revolution. And only after much improvisation, coercion, persuasion, fear, and luck did thirteen British colonies become the United States of America.

This matters because revolutions are often remembered backward. The outcome becomes the explanation. The Declaration of Independence makes separation appear clean and principled; the victory at Yorktown makes success seem almost destined; the later rise of the United States gives the Revolution the shine of inevitability. But for those who lived through it, the crisis was untidy, uncertain, and frightening. In 1763, most colonists in British North America thought of themselves as loyal subjects of George III. They had just emerged from the Seven Years’ War — known in America as the French and Indian War — as members of a victorious empire. Britain had defeated France in North America and gained vast new territories. The imperial future looked expansive. It also looked expensive.

The Revolution’s origins lay in that contradiction. Britain had won a global war but inherited a global bill. Its ministers believed that the American colonies, long protected by British arms and enriched by imperial trade, should contribute more to imperial revenue and administration. Many colonists did not object to empire as such; indeed, they had often benefited from it. What they resisted was Parliament’s claim to govern them in matters they believed belonged to their own colonial assemblies. The quarrel over taxes was therefore never merely about money. The sums raised by measures such as the Stamp Act were less important than the principle behind them. Could a legislature in which Americans had no elected representatives impose internal taxes on them? Could Parliament alter colonial charters, suspend assemblies, or use troops to enforce compliance? Where did sovereignty reside in a composite empire?

These were constitutional questions, but they did not remain confined to lawyers, pamphleteers, and gentlemen politicians. One reason the American crisis became revolutionary was that abstract claims about rights found practical expression in streets, taverns, churches, newspapers, ports, and households. Merchants organized boycotts. Artisans joined crowds. Women participated in non-importation campaigns by changing patterns of consumption and production. Printers turned local grievances into continental arguments. Enslaved people listened carefully to talk of liberty and drew their own conclusions, sometimes seeking freedom with the British, sometimes pressing Americans to confront the hypocrisy at the heart of their cause. Native nations, facing settler expansion with or without British restraint, judged the conflict according to their own urgent interests. The Revolution was not one movement but many overlapping struggles, some aligned and some sharply opposed.

Seen comparatively, the American Revolution belongs to a larger age of imperial crisis and political transformation. The eighteenth-century Atlantic world was a place of commercial expansion, war finance, state-building, slavery, and ideological ferment. Britain was hardly the only empire trying to tighten administration and extract revenue. Spain and France, too, pursued reforms to make their empires more profitable and governable. Nor were Americans the only people to speak the language of rights. Across Europe and the Atlantic, arguments about representation, natural rights, religious liberty, and the limits of monarchy circulated through books, sermons, correspondence, and rumor. The American case was distinctive not because colonists invented liberty from scratch, but because they transformed inherited British constitutional claims into a successful rebellion against British rule.

That transformation required characters as well as causes. Samuel Adams, Benjamin Franklin, John Adams, Thomas Jefferson, George Washington, Abigail Adams, Patrick Henry, Thomas Paine, Mercy Otis Warren, Joseph Brant, Phillis Wheatley, Lord North, George III, and many others appear in this story not as marble figures but as political actors operating under pressure. Some were cautious until events narrowed their options. Some radicalized early. Some sought compromise and failed. Some saw in the imperial crisis an opening to advance freedom; others saw a threat to order, property, or survival. Their choices mattered, but they mattered within structures larger than themselves: imperial debt, Atlantic commerce, colonial self-government, slavery, land hunger, Protestant political culture, and the military realities of fighting a transoceanic war.

The consequences were equally layered. The Revolution created a republic that proclaimed universal principles while protecting many forms of exclusion. It accelerated democratic political habits among white men while leaving slavery intact in much of the new nation. It weakened some hierarchies and strengthened others. It inspired reformers and revolutionaries abroad, including in France, Haiti, Latin America, Ireland, and beyond, yet it also demonstrated how easily the language of liberty could coexist with conquest and bondage. For Britain, the loss of the colonies was a shock but not the end of empire; indeed, British imperial power would later expand dramatically in Asia, Africa, and the Pacific. For the new United States, independence was less an ending than a beginning: the start of a long argument over what the Revolution had actually promised.

This essay explains why the American Revolution happened by treating it not as a patriotic morality play, nor as a simple tax revolt, but as a political rupture shaped by imperial economics, constitutional conflict, popular mobilization, and enduring ideas about liberty and power. Its central question is not merely why Americans rebelled, but how a dispute inside the British Empire became a revolution with global consequences. The answer lies in the combustible mixture of principle and interest, fear and aspiration, rhetoric and force. Empires often survive disagreement. In British America after 1763, disagreement became resistance; resistance became rebellion; and rebellion, against long odds, became independence.

Historical Analysis

The American Revolution is easiest to misunderstand when viewed too narrowly. If it is treated only as a colonial protest against taxes, it becomes strangely disproportionate: a war for independence over tea duties and stamped paper. If it is treated only as the birth of modern liberty, it becomes too clean: a noble uprising mysteriously compatible with slavery, Indigenous dispossession, and property restrictions on political power. The Revolution makes more sense when placed in a wider eighteenth-century world of empires under strain, wars financed by debt, expanding commerce, and political societies increasingly fluent in the language of rights.

In this global frame, the Revolution was not an isolated eruption but one episode in a broader crisis of imperial management. Britain’s victory in the Seven Years’ War in 1763 made it the dominant Atlantic power, but victory brought problems as well as prestige. The empire had acquired vast new territories and a heavy public debt. London’s ministers believed the colonies should contribute more to their own defense and administration. This was not, from an imperial accountant’s perspective, an absurd proposition. Britain had spent lavishly fighting France in North America. British taxpayers already bore a considerable burden. The colonies were prosperous, growing, and protected by the Royal Navy.

Yet empires are not governed by balance sheets alone. British America had developed habits of self-government that were not merely decorative. Colonial assemblies taxed local populations, managed budgets, and defended their privileges with increasing confidence. The issue after 1763 was therefore not simply whether Americans would pay, but who had the authority to decide. Parliament claimed sovereignty over the empire. Colonial opponents increasingly argued that taxation required representation and that internal taxation belonged to their own elected assemblies. Both sides appealed to the British constitution; both believed they were defending lawful order. The tragedy, and then the revolution, lay in the fact that they meant different things by it.

Comparative history sharpens the point. Many eighteenth-century empires were composite structures, held together by bargains, exemptions, charters, and local privileges. The Spanish monarchy governed American territories through layered institutions and negotiated authority. The Dutch empire depended heavily on commercial corporations and local arrangements. The British Empire, too, had grown through improvisation rather than design. After 1763, Britain attempted to make its American empire more administratively coherent and fiscally useful. The colonies responded as political communities that had come to see inherited liberties as shields against metropolitan innovation. What London regarded as reform, many colonists experienced as encroachment.

This pattern was not unique. Revolutions often begin when states try to modernize revenue collection or centralize authority. The French Revolution would later erupt from a fiscal crisis made worse by war debts, social privilege, and failed reform. In Spanish America, imperial reforms in the eighteenth century strengthened royal administration but also generated resentment among Creole elites. The American case differed because resistance moved quickly from constitutional protest to mass mobilization, and because Britain’s distance from the colonies made coercion expensive and uncertain. Geography did not cause independence, but it gave resistance room to breathe.

Popular mobilization transformed elite complaint into revolutionary politics. Merchants opposed trade restrictions; lawyers wrote pamphlets; printers spread arguments; artisans joined committees; farmers gathered in militia companies; women participated in boycotts and household production. Crowds enforced nonimportation agreements, intimidated officials, and turned abstract constitutional claims into visible power on the streets. This mattered. Revolutions do not happen simply because intellectuals produce arguments. They happen when arguments are adopted by networks capable of applying pressure. In British America, taverns, churches, newspapers, town meetings, committees of correspondence, and provincial congresses created an alternative political infrastructure before independence was formally declared.

The Revolution’s ideology was both radical and conservative. It was radical in insisting that legitimate government rested on consent and that rulers could be resisted when they violated fundamental rights. It was conservative in its attachment to inherited liberties, local autonomy, Protestant fears of corruption, and property-based assumptions about political order. Americans did not initially set out to invent a new world from first principles. Many claimed they were preserving an old one: the rights of Englishmen, the balance of the constitution, the liberties secured by resistance to tyranny in Britain’s own past. Only gradually did this defensive language become a case for independence and republican government.

The global comparison also reveals the Revolution’s limits. Unlike the Haitian Revolution, which directly destroyed slavery in a slave society through the action of the enslaved themselves, the American Revolution left slavery deeply entrenched in the South even as northern states began gradual emancipation. Unlike the French Revolution, it did not attempt a sweeping social reconstruction of church, nobility, calendar, and state. Unlike many later anti-colonial revolutions, it was led largely by settler elites who sought independence from an empire while continuing expansion across Indigenous lands. It was anti-imperial in relation to Britain, but not anti-colonial in relation to Native peoples.

That contradiction was not incidental. The same imperial crisis that produced arguments over taxation also involved western land, military protection, and sovereignty beyond the Appalachian frontier. Britain’s attempt to manage western expansion after 1763 angered colonists who saw land as opportunity, wealth, and inheritance. For many Native nations, British authority could be a barrier—imperfect but sometimes useful—against unchecked settler expansion. American independence removed that barrier. In global terms, the Revolution created a republic and accelerated a continental settler empire.

Its success altered the political imagination of the Atlantic world. The American example showed that colonies could break from a European empire and survive. It gave reformers and revolutionaries a vocabulary of natural rights, written constitutions, republican citizenship, and popular sovereignty. But it also offered a more ambiguous lesson: liberty could be proclaimed in universal terms while distributed unequally in practice. That ambiguity would travel widely. So would the inspiration.

The American Revolution happened because an imperial reform program collided with colonial political expectations at a moment when war, debt, commerce, ideology, and mobilization made compromise increasingly difficult. In comparative perspective, it belongs to the age of Atlantic revolutions, but it was not simply the first act in a single drama of liberation. It was a rupture inside empire that produced both a republic of enduring ideals and a new power with its own exclusions and ambitions. Its greatness and its contradictions were born together.

Contemporary Global Dynamics

The American Revolution belongs to the eighteenth century, but the questions it sharpened have not retired. Who may tax whom? When does law become domination? Can a distant authority govern legitimately without meaningful consent? What happens when universal language about rights meets unequal distributions of power, wealth, race, and territory? These were not merely powdered-wig dilemmas. They remain the grammar of modern politics, audible in disputes over sovereignty, global institutions, democratic backsliding, debt, trade, migration, and the rights of peoples living under states they did not choose.

One reason the Revolution still matters is that it helped make sovereignty portable. Before 1776, empires were the normal architecture of global power. Afterward, the claim that a people could dissolve imperial bonds and constitute itself as a nation gained a durable political form. The Declaration of Independence did not invent self-determination in the modern sense, but it furnished one of its most influential scripts: a list of grievances, an appeal to universal principles, and a final assertion that legitimacy rests on consent rather than inherited command. Later movements—from Latin American independence struggles to anti-colonial campaigns in Asia and Africa—would adapt this script to circumstances far removed from British North America.

Yet the contemporary world also exposes the Revolution’s unresolved tension between independence and inclusion. The United States was born by rejecting imperial subordination, but it did not create an egalitarian order. Enslaved people, Indigenous nations, women, landless men, and many religious and ethnic minorities lived within or beside a republic whose promises applied unevenly. That pattern has global echoes. Many postcolonial states won sovereignty from empire only to confront internal hierarchies, border conflicts, ethnic domination, economic dependency, or military rule. Independence can answer the question of external control while leaving open the harder question of who counts as “the people” inside the new political community.

This is why the American Revolution remains useful in comparative analysis but dangerous as a simple model. Its success can tempt admirers into a tidy story: liberty declared, monarchy defeated, republic founded. The fuller lesson is more demanding. Revolutionary legitimacy depends not only on overthrowing an old authority but on constructing institutions capable of reconciling liberty with order, majority rule with minority rights, and political ideals with material realities. The Americans were unusually successful in creating durable constitutional machinery. They were far less successful in resolving the moral and political crises embedded in slavery and settler expansion. Their achievement and their failure were not separate chapters; they were interwoven from the beginning.

Contemporary global politics often turns on similar collisions between principle and power. International law affirms sovereign equality, yet great powers still shape the options of weaker states. Global markets promise opportunity, yet debt, sanctions, resource dependency, and trade rules can narrow democratic choice. Human rights language is universal, yet enforcement is selective. Popular sovereignty is celebrated, yet populist leaders may use elections to weaken courts, legislatures, the press, and civil society. The old imperial question—who governs, for whose benefit, and by what right—has migrated into new institutions and new vocabularies.

The Revolution also speaks to modern protest politics. In the imperial crisis of the 1760s and 1770s, constitutional arguments did not remain confined to pamphlets and assemblies. They moved through taverns, churches, newspapers, committees, boycotts, crowd actions, and local conventions. Politics became participatory before it became independent. Modern movements likewise depend on translation: abstract grievances must become shared stories, rituals, slogans, networks, and pressure. The Stamp Act crisis and the nonimportation campaigns showed how economic behavior could be politicized; consumers became actors in constitutional conflict. Today, boycotts, sanctions campaigns, digital mobilization, and street protest operate on a similar premise: power is not only held in formal office but dispersed through commerce, communication, and collective refusal.

There is, however, a crucial difference. The American Revolution unfolded in a world where political communication moved at the speed of ships, horses, and print. Contemporary crises move at the speed of platforms, financial flows, satellite images, and viral outrage. This acceleration can enlarge participation, but it can also compress judgment. Revolutionary politics has always depended on persuasion; modern politics often rewards performance. The eighteenth-century pamphleteer and the twenty-first-century influencer are not the same creature, though both understand that legitimacy is fought over in public language.

The global afterlife of the American Revolution is therefore neither a monument nor a manual. It is a repertoire: rights, consent, constitutionalism, federalism, armed resistance, civic mobilization, written charters, and suspicion of concentrated power. Different societies have drawn from that repertoire in different ways. Some have emphasized republican institutions; others the right of national liberation; others the language of equality that the founding generation proclaimed more fully than it practiced. The Revolution’s influence lies partly in this adaptability. It can inspire conservatives defending constitutional limits, liberals expanding civil rights, radicals denouncing hierarchy, and nationalists asserting independence. A revolution that began in argument has remained available for argument ever since.

In the contemporary world, then, the American Revolution is best understood not as an origin myth to be revered or debunked, but as an early case study in the modern problem of legitimate power. It shows how fiscal policy can become constitutional conflict, how empire can generate nationalism, how elites can mobilize popular energy they cannot fully control, and how noble ideals can coexist with exclusion and expansion. Above all, it reminds us that liberty is never self-defining. Every generation that invokes it must answer the same uncomfortable question the Revolution left behind: liberty for whom, secured by what institutions, and at whose expense?

Comparative Shared Principles

For all the differences among the American, French, Haitian, Latin American, and later anti-colonial revolutions, they shared a family resemblance. Each began in a particular grievance—a tax, a monopoly, a racial order, an imperial war, a blocked reform—and then climbed toward abstraction. The complaint became a claim. The claim became a principle. The principle demanded institutions.

This is one reason the American Revolution traveled so well. Its facts were local: colonial assemblies, customs officers, tea duties, western lands, and the peculiar constitutional habits of British America. Its vocabulary was portable. “Rights,” “liberty,” “consent,” “representation,” “the people,” and “constitution” were not American inventions, but the Revolution fused them into a usable political grammar. Other societies could translate that grammar into their own disputes, even when the translation changed the meaning.

The first shared principle was that legitimate government rests on consent. In America, this was sharpened by the imperial problem: Parliament claimed authority over colonies that elected no members to it. The slogan “no taxation without representation” was not merely an objection to paying more. It was an argument about the architecture of power. A government that could take property without meaningful representation could, in theory, take anything. The fiscal issue became constitutional because money revealed sovereignty.

That logic echoed elsewhere. French revolutionaries in 1789 did not rebel against a distant parliament but against a domestic monarchy and a privileged social order. Yet they too insisted that authority must be re-grounded in the nation. The old corporate world of estates, orders, and inherited privilege gave way, at least in principle, to the idea that sovereignty resided in the people. Latin American revolutionaries later adapted the same claim against Spanish imperial rule: if legitimate authority flowed from the people, and if imperial legitimacy had collapsed or become intolerable, then Americans in the Spanish colonies could form their own political communities.

The second shared principle was that rights could be stated as general truths rather than granted as favors. This marked a decisive change in political language. Earlier English constitutionalism often described liberties as inherited privileges—ancient rights of Englishmen, secured by custom and precedent. The American Revolution retained much of that older inheritance, but the Declaration of Independence pushed beyond it. Its language of equality and unalienable rights suggested that political claims did not depend only on history. They could be made from human nature.

That move was explosive. It inspired admiration, imitation, and embarrassment. The French Declaration of the Rights of Man and of the Citizen made the universal ambition explicit. The Haitian Revolution then exposed the central contradiction with terrifying clarity. If rights were universal, how could slavery survive? Enslaved people in Saint-Domingue did not merely borrow European revolutionary language; they forced it to confess its implications. Haiti turned the rhetoric of liberty against both colonial rule and racial slavery, revealing that the most radical meaning of the age’s principles lay not in their eloquence but in their consistent application.

The third shared principle was constitutionalism: the belief that power should be bound by rules, separated among institutions, and made answerable to the governed. The American Revolution was unusual in how quickly it became a constitution-making enterprise. State constitutions appeared even before independence was fully secured. The Articles of Confederation attempted one model of union; the federal Constitution replaced it with another. The Revolution did not end with the rejection of authority. It led to the harder business of designing authority that could govern without becoming arbitrary.

This mattered globally because revolutions are often better at destroying legitimacy than rebuilding it. A crowd can pull down a symbol in an afternoon; a durable constitutional order takes years of argument, compromise, disappointment, and enforcement. The American example suggested that revolution need not mean permanent upheaval. It could produce written limits, elected offices, federal arrangements, courts, and procedures for change. Later reformers and revolutionaries studied this institutional lesson as closely as the rhetoric of 1776.

Yet shared principles did not produce shared outcomes. Consent could empower democracy, but it could also be narrowed to exclude women, the propertyless, Indigenous peoples, enslaved people, and political opponents. Rights could be universal in theory and selective in practice. Constitutionalism could restrain tyranny, but it could also protect entrenched interests. Federalism could reconcile diversity, or it could shelter injustice. The same principles that gave the American Revolution its global reach also gave later generations grounds to indict it.

This tension is not a footnote; it is the engine of revolutionary modernity. The American Revolution helped popularize a style of politics in which governments must justify themselves before principles larger than custom, dynasty, or conquest. Once that standard exists, it rarely stays obedient. People excluded from the original settlement can use its own language against it. Abolitionists, suffragists, civil-rights activists, labor organizers, anti-colonial leaders, and constitutional reformers all understood this. They did not need the founders to have been saints. They needed the founding vocabulary to contain promises that could be redeemed more broadly than its authors intended.

Comparatively, then, the deepest shared principle was not any single institutional design. It was the conviction that power is not self-legitimating. It must answer to rights, representation, law, and public judgment. That conviction took different forms in Philadelphia, Paris, Port-au-Prince, Caracas, Warsaw, Delhi, and countless other places where political communities argued over liberty and authority. The American Revolution was one early and influential chapter in that wider story: not the source of all modern freedom, but a demonstration that principles, once released into public life, can become more ambitious than the societies that first proclaim them.

Future Horizons and Secular Trends

The American Revolution belongs to the eighteenth century, but it keeps escaping its century. It began in disputes over taxes, trade, courts, charters, western lands, military occupation, and the authority of Parliament. Yet its afterlife has been larger because those quarrels were translated into durable political questions: Who may rule? By what right? How far may a distant center govern local communities? When does law become coercion rather than consent? These questions did not end at Yorktown. They became part of the operating system of modern politics.

The first secular trend is the long decline of inherited authority as a sufficient explanation for power. Monarchy did not vanish after 1776; indeed, much of the world remained monarchical for generations. Empire did not collapse overnight; the nineteenth century was, in many ways, an imperial century. But legitimacy increasingly required argument. Kings, parliaments, parties, colonial governors, revolutionary committees, military juntas, and presidents all had to present themselves as servants of some public principle. The American Revolution helped accelerate this change by making sovereignty appear transferable: not a sacred possession of the Crown, but an authority that could be reclaimed, redistributed, and institutionalized.

That shift did not make politics gentle. If anything, it made politics more intense. Once rule required justification, rival justifications multiplied. Liberals spoke of rights; democrats of majorities; nationalists of peoples; socialists of class emancipation; imperial reformers of civilizing missions; anti-colonial movements of self-determination. The American case offered one influential formula: written constitutions, representative institutions, divided powers, and a rhetoric of liberty grounded in natural rights. But the formula was not self-executing. Its exclusions were not accidental blemishes on an otherwise completed design. They were central contradictions that later generations would force into the open.

A second secular trend is the expansion of the political community. In 1776, “the people” was a revolutionary phrase, but also a restricted one. Political participation remained heavily gendered, racialized, and often tied to property and status. Over the next two centuries, however, the logic of consent proved difficult to confine. If government derived authority from the governed, the obvious next question was who counted among them. The struggle over that question reshaped the United States through abolition, Reconstruction, women’s suffrage, labor politics, civil rights, Native sovereignty movements, immigration battles, and arguments over voting rights that remain alive today.

This pattern appears globally. Revolutions and reform movements repeatedly begin by invoking a people narrower than the one their own principles imply. The French Revolution proclaimed rights while struggling over slavery, women’s citizenship, and colonial hierarchy. Latin American independence movements attacked imperial rule while often preserving sharp social inequalities. Anti-colonial movements in Asia and Africa converted the language of national self-rule into demands for mass citizenship, economic justice, and cultural dignity. The American Revolution was neither the origin nor the owner of these developments. But it supplied a prominent early demonstration that constitutional language could be used not only to found a regime, but to challenge it from within.

A third trend is the permanent tension between liberty and state capacity. The colonists rebelled against an empire seeking revenue and administrative control after a costly global war. The irony is that successful independence required Americans to build a state capable of taxation, diplomacy, war-making, debt management, and territorial governance. The Articles of Confederation proved too weak for many national purposes; the Constitution created a stronger federal framework. This dilemma has never disappeared. Modern societies want liberty from arbitrary power, but they also demand roads, courts, defense, schools, public health, disaster relief, financial stability, and protection from private coercion. The question is not whether power will exist, but how it will be authorized, limited, monitored, and corrected.

Here the Revolution’s legacy is double-edged. Suspicion of centralized power has often protected pluralism, local autonomy, and civil society. It has also made collective action harder, especially when national problems require national solutions. Federalism can be a school of liberty; it can also be a maze in which responsibility hides. The same institutional fragmentation that prevents tyranny may frustrate reform. Future political conflicts in the American tradition will continue to turn on this old revolutionary balance: how to give government enough energy to govern without granting it a blank check.

A fourth trend is the fusion of political liberty with economic grievance. The Revolution was not caused by abstract philosophy alone. It emerged from an imperial economy of regulation, debt, taxation, credit, land speculation, and commercial restriction. Merchants, farmers, artisans, smugglers, creditors, debtors, and consumers all encountered empire differently. Boycotts and nonimportation agreements turned household consumption into political action. Tea became more than tea. It became a symbol of who could command markets, bodies, and choices.

Modern politics remains full of such transformations. Tariffs, supply chains, inflation, housing costs, resource extraction, trade rules, and debt can become constitutional questions when people interpret economic pressure as political subordination. The cry may no longer be “no taxation without representation,” but the structure is familiar: material burdens become explosive when they seem imposed by remote authorities insulated from accountability. In this sense, the Revolution’s causes remain legible in contemporary disputes over globalization, regional inequality, fiscal policy, and technocratic governance.

The final horizon is informational. The eighteenth-century Revolution depended on pamphlets, newspapers, sermons, tavern debates, committees of correspondence, and public rituals. It was a revolution of print as well as politics. Its leaders did not merely argue; they circulated arguments. They created a shared crisis across colonies that differed in economy, religion, and social structure. Without communication networks, grievances would have remained local. With them, imperial policy became a continental drama.

Today’s communication systems are faster, broader, and more volatile. They can democratize speech, expose abuses, and mobilize the excluded. They can also reward fury, conspiracy, and performative certainty. The revolutionary inheritance therefore faces a modern stress test. A republic built on public judgment requires a public capable of judgment. Institutions matter, but so do habits: patience with evidence, tolerance of defeat, willingness to distinguish opposition from treason, and the civic modesty to admit that no faction permanently embodies the people.

The secular trend since the eighteenth century is not a straight march toward liberty. It is the widening of the arena in which power must defend itself. The American Revolution helped enlarge that arena by turning imperial protest into constitutional creation and local grievance into universal argument. Its future significance will depend less on reverence for its founders than on whether later societies can preserve its most demanding insight: that authority is legitimate only when it remains answerable to those who live under it.
