Monroe Doctrine

Based on Wikipedia: Monroe Doctrine

A Bluff That Shaped the World

In December 1823, President James Monroe stood before Congress and essentially told all of Europe to stay out of the Americas. It was audacious. It was bold. And it was, at the time, completely unenforceable.

The United States had no real navy to speak of. Its army was modest at best. The great powers of Europe—Britain, France, Austria, Prussia, Russia—controlled vast swaths of territory across the globe and commanded military forces that could have swatted away American objections like gnats. Prince Klemens von Metternich of Austria, one of the most influential diplomats in European history, privately fumed that Monroe's declaration was a "new act of revolt" that would "reanimate the courage of every conspirator."

And yet. Two centuries later, we still talk about the Monroe Doctrine as one of the foundational pillars of American foreign policy. How did a bluff become reality?

The World in 1823

To understand why Monroe made his famous declaration, you need to understand what the Americas looked like in the early 1820s.

The Spanish Empire was collapsing. For three centuries, Spain had controlled most of Central and South America, extracting enormous wealth in gold, silver, and agricultural products. But the Napoleonic Wars had weakened Spain catastrophically, and across Latin America, independence movements were succeeding one after another. Simón Bolívar was liberating what would become Venezuela, Colombia, Ecuador, Peru, and Bolivia. Mexico had declared independence in 1821. Argentina, Chile, and others were breaking free.

This created a problem for the old monarchies of Europe. The Congress of Vienna in 1814 and 1815 had been all about restoring order after Napoleon's rampage across the continent. The conservative powers—Austria, Prussia, and Russia—had formed what they called the Holy Alliance, dedicated to defending monarchical government against the rising tide of republicanism and revolution. They had already authorized military intervention to restore the Bourbon monarchy in Spain itself.

The fear in Washington was straightforward: Would these same powers now turn their attention to the Americas? Would they help Spain reconquer its lost colonies? France had already agreed to restore the Spanish monarchy in exchange for Cuba. The newly independent nations of Latin America, fragile and still organizing themselves, could be easy targets.

An Unexpected Ally

Here's where things get interesting. Britain, the nation that had burned Washington just nine years earlier during the War of 1812, actually supported the American position.

Why would Britain care? The answer was economic self-interest dressed up as principle.

The British economy was transforming. The Industrial Revolution was in full swing, and Britain's factories were churning out manufactured goods at unprecedented rates. These goods needed markets. Latin America, newly independent and eager to trade, represented enormous commercial opportunity. If Spain reconquered its former colonies, it would reimpose the old mercantilist trade policies that had kept British merchants out for centuries.

Britain actually offered to issue a joint statement with the United States opposing European intervention in the Americas. American leaders declined—the War of 1812 was too recent, and the idea of partnering with the former enemy felt wrong. But Britain's position meant something crucial: the Royal Navy, by far the most powerful maritime force on Earth, would effectively enforce the doctrine even without formal agreement.

For decades, the Monroe Doctrine was less an American policy than a British one. The United States claimed the principle. The Royal Navy made it real.

What Monroe Actually Said

The doctrine itself wasn't a separate document or declaration. It was embedded in Monroe's annual message to Congress—what we now call the State of the Union address. The actual language was crafted primarily by John Quincy Adams, the Secretary of State who would later become president himself.

The core of the doctrine rested on two propositions.

First, the Americas were closed to future European colonization. As Monroe put it: "The American continents, by the free and independent condition which they have assumed and maintain, are henceforth not to be considered as subjects for future colonization by any European powers."

Second—and this is often overlooked—the United States promised to stay out of European affairs in return. America would not interfere with existing European colonies in the Americas, and would not meddle in the internal politics of European nations. It was a bargain: you stay out of our hemisphere, we stay out of yours.

There was also a practical trigger for the timing. Russia had issued a proclamation in 1821 claiming rights to the Pacific Northwest and forbidding non-Russian ships from approaching the coast. This was a direct challenge to American interests, and part of what prompted the broader statement of hemispheric principle.

Years of Irrelevance

For most of the nineteenth century, the Monroe Doctrine was honored mostly in the breach.

In 1833, Britain reasserted control over the Falkland Islands—islands that Argentina claimed and that, under a strict reading of the doctrine, should have been protected from European colonization. The United States did nothing. Historian George C. Herring wrote that this inaction "confirmed Latin American and especially Argentine suspicions of the United States."

From 1838 to 1850, French and British naval forces blockaded Argentina. Again, the United States did nothing.

The most dramatic violation came during the American Civil War. Napoleon III of France—nephew of the original Napoleon—invaded Mexico in 1862 and installed a puppet emperor, Maximilian I, an Austrian archduke. This was precisely the kind of European intervention the Monroe Doctrine was supposed to prevent. But with the United States tearing itself apart in the bloodiest conflict in its history, there was nothing Washington could do about it.

Only after the Civil War ended did the doctrine show its teeth. In 1865, the United States massed troops on the Mexican border. The message was unmistakable. French forces withdrew. Mexican nationalists captured Maximilian and executed him by firing squad in 1867.

Secretary of State William Seward declared triumphantly that "the Monroe Doctrine, which eight years ago was merely a theory, is now an irreversible fact."

The Doctrine Gets Teeth

By the end of the nineteenth century, the United States had transformed. It was no longer the struggling young republic of Monroe's day. It had industrialized. It had expanded to the Pacific. It had built a real navy. And it was ready to enforce its hemispheric claims.

The Venezuelan crisis of 1895 marked a turning point. Venezuela was in a territorial dispute with Britain over its border with British Guiana—present-day Guyana. The Venezuelans were clever: they hired a former American ambassador to argue that Britain's position violated the Monroe Doctrine.

President Grover Cleveland's Secretary of State, Richard Olney, sent Britain a note containing one of the most breathtaking assertions of American power ever committed to paper: "The United States is practically sovereign on this continent, and its fiat is law upon the subjects to which it confines its interposition."

The British prime minister was outraged. German Chancellor Otto von Bismarck called the doctrine an "uncommon insolence." But in the end, Britain backed down. An international tribunal settled the dispute, and though the boundary award mostly favored Britain, the principle had been established: the United States would defend its interpretation of the doctrine, and major powers would think twice before challenging it.

From Defensive Shield to Imperial Tool

Something important happened to the Monroe Doctrine after 1898. It transformed from a defensive principle—keeping Europeans out—into a justification for American intervention throughout the hemisphere.

The Spanish-American War of 1898 was the pivot point. The United States defeated Spain, took control of Cuba and Puerto Rico, and acquired the Philippines on the other side of the world. America was now an imperial power in its own right.

Theodore Roosevelt articulated the logical extension of the doctrine in 1904 with what became known as the Roosevelt Corollary. If the Monroe Doctrine meant European powers couldn't intervene in Latin America, and if some Latin American country behaved in a way that might invite European intervention—say, by defaulting on debts to European creditors—then the United States had not just the right but the duty to intervene first.

This was a radical reinterpretation. Monroe had said: Europe, stay out. Roosevelt was saying: We'll go in whenever we think it's necessary.

Over the following decades, the United States intervened repeatedly across the Caribbean and Central America. Marines occupied Nicaragua, Haiti, the Dominican Republic. The United States backed coups and installed friendly governments. The Monroe Doctrine, originally framed as protecting Latin American independence from European meddling, became the justification for American meddling instead.

The Good Neighbor Policy and Beyond

By the 1930s, the contradictions had become embarrassing. Franklin Roosevelt—Theodore's distant cousin—announced a "Good Neighbor Policy" that explicitly renounced the right of intervention. The United States would work with Latin American nations as partners, not dominate them as a regional hegemon.

In 1933, the United States co-founded the Organization of American States, institutionalizing the principle of multilateral cooperation rather than unilateral American action. The Monroe Doctrine was reinterpreted by lawyers and diplomats to emphasize non-intervention and collective security.

But old habits die hard. During the Cold War, fears of Soviet influence in the Western Hemisphere led to a new round of interventions. The Central Intelligence Agency engineered coups in Guatemala and Chile. The United States backed anti-communist forces throughout the region. President John F. Kennedy invoked Monroe's legacy during the Cuban Missile Crisis. President Ronald Reagan did the same while supporting the Contras in Nicaragua.

The language changed. The justifications shifted from keeping out European monarchies to keeping out Soviet communism. But the underlying logic—that the United States had special rights and responsibilities in the Western Hemisphere—remained remarkably consistent.

A Doctrine's Strange Afterlife

The Monroe Doctrine never officially ended. There was no treaty, no formal repudiation. It simply evolved, was reinterpreted, fell out of fashion, and occasionally returned.

Secretary of State John Kerry declared in 2013 that "the era of the Monroe Doctrine is over." But just a few years later, officials in the Trump administration were invoking it again in the context of Venezuela and Chinese investment in Latin America. President Donald Trump himself referenced Monroe's principles when discussing hemispheric policy.

This persistence tells us something about the doctrine's nature. It was never really a precise legal principle. It was more like a mood, a posture, a way of thinking about America's place in the world. The Western Hemisphere was America's neighborhood, and the United States would always have opinions about who else got to operate there.

The View from Latin America

How did Latin Americans themselves feel about all this?

Initially, the reaction was grateful. Simón Bolívar and other leaders of the independence movements welcomed Monroe's words. They understood perfectly well that the United States couldn't actually enforce the doctrine alone—that British naval power was the real guarantor of their independence. But having the growing republic to the north publicly commit to opposing European reconquest was still valuable.

The gratitude curdled over time. Diego Portales, a Chilean statesman, warned early on: "For the Americans of the north, the only Americans are themselves." As the nineteenth century progressed and the twentieth century brought wave after wave of American intervention, this cynical assessment seemed increasingly accurate.

The Monroe Doctrine became, in Latin American eyes, less a shield protecting their independence than a claim of ownership over their affairs. The United States wasn't keeping Europeans out so much as keeping the hemisphere for itself. Pan-American solidarity, they discovered, meant solidarity on American terms.

What It All Means

The Monroe Doctrine offers a fascinating case study in how foreign policy actually works.

Monroe announced a principle his country couldn't enforce. For decades, it was enforced—when it was enforced at all—by a rival power pursuing its own interests. Eventually, American power grew to match American ambitions, and the doctrine became real. Then it transformed into something its originators wouldn't have recognized, justifying the very kind of intervention in sovereign nations it had originally opposed.

Ideas in foreign policy are tools. They get picked up, put down, reinterpreted, and repurposed as circumstances change. The Monroe Doctrine of 1823 bears only superficial resemblance to the Monroe Doctrine of 1904, or 1962, or 2019. The name stayed the same. The meaning shifted with American power and American interests.

There's also a lesson about bluffing. Monroe's declaration was, in military terms, almost pure bluff. But bluffs can become reality if circumstances align. Britain's self-interested support made the doctrine viable. American industrial growth made it enforceable. And by the time anyone thought to challenge it directly, the United States had become powerful enough to back up its claims.

Two hundred years later, the Western Hemisphere remains firmly in the American sphere of influence. European powers long ago accepted that the Americas were off-limits for colonial expansion. The debates now are about whether the doctrine's logic applies to Chinese economic investment, or Russian diplomatic maneuvering, or any other form of extra-hemispheric influence.

James Monroe couldn't have predicted any of this. He was responding to the immediate fears of his time—the Holy Alliance, Spanish reconquest, Russian claims in the Pacific Northwest. But the doctrine he articulated took on a life of its own, shaping American foreign policy for generations and defining the hemisphere's political geography in ways that persist to this day.

It remains one of the most consequential bluffs in diplomatic history.
