History offers sobering examples of republics that collapsed into authoritarian regimes. In each case we see common patterns. This includes very well known falls like the Weimar Republic’s fall into Nazi Germany, lesser known instances like the early Republic of China (1912-1916) under Yuan Shikaiπ, and many older attempts at permeant republican societies.

What does it look like? Ambitious leaders exploit crises to overreach their executive power. Lawmaking bodies fail to check these abuses in a meaningful way. And then ordinary people acquiesced, sometimes even welcoming strongman rule during chaos.

Even though many of the examples of these failures we may think of occurred well after the Revolutionary War in the United States, the founders were keenly aware of these failure modes. They designed the U.S. Constitution with deliberate checks and balances to prevent the fate of past republics, drawing on lessons from history - and documenting many of those key insights in the Federalist Papers.

I wanted to take a closer look at this, and writing this blog became my excuse to do so. And I want to focus on those three steps that I mentioned: executive overreact, legislative inaction, and public acquiescence - and then think about how the United States is specifically designed to attempt to prevent the types of republican failures we’ve seen in the past.

Executive Overreach: When Leaders Seize Too Much Power

A republic entrusts elected leaders with limited powers, not unchecked authority. Executive overreach occurs when a leader subverts these limits and accumulates power that no single branch should hold. The Founding Fathers warned that concentrating all government powers in one person or body is tyranny: “The accumulation of all powers, legislative, executive, and judiciary, in the same hands…may justly be pronounced the very definition of tyranny,” James Madison wrote in Federalist No. 47. To prevent this, the U.S. Constitution creates separate branches and distributes authority - making them “co-equal branches” of the federal government.

As Federalist No. 51 explains:

Ambition must be made to counteract ambition”

Each branch must have the means and motive to resist encroachments by the others . If “men were angels, no government would be necessary,” but since they are not, the government must be obliged “to control itself” through internal checks and balances.

Nazi Germany (Weimar Republic’s collapse): In the early 1930s, Germany’s Weimar Republic was a democracy on paper, but economic depression and political deadlock created an opening for executive abuse. After Adolf Hitler was appointed chancellor in January 1933, he moved swiftly to dismantle checks on his power.

Exploiting emergency provisions, Hitler persuaded President Hindenburg to issue the Reichstag Fire Decree, suspending civil liberties. He then pushed through the Enabling Act of 1933, a law that gave Hitler’s cabinet the power to enact laws without the Reichstag (parliament) or presidential approval. This Act effectively let Hitler bypass the constitution’s checks and rule by decree, laying the legal foundation for his dictatorship.

By combining the offices of President and Chancellor after Hindenburg’s death, Hitler completed his power grab and proclaimed himself Führer, wielding absolute authority. In short, Hitler manipulated the democratic system to destroy democracy and create a dictatorship. The Weimar Republic’s fate shows how quickly an executive can accrue near-absolute power in a crisis, especially if constitutional safeguards are weak or ignored.

China’s First Republic: The early Republic of China offers a lesser-known but vivid example of executive overreach. After the 1911 revolution ended imperial rule, a constitutional republic was proclaimed in 1912. General Yuan Shikai soon became president, and rather than uphold republican institutions, he systematically undermined them.

In 1913, when the new National Assembly and elected parliament asserted themselves, Yuan resorted to violence and coercion. He allegedly ordered the assassination of Song Jiaoren, the leader of the majority Kuomintang (Nationalist) Party, who was a pro-democracy advocate. Yuan then banned the Kuomintang, purged hundreds of opposition lawmakers, and ultimately dissolved Parliament outright in 1914.

Ruling by decree and backed by the Beiyang Army, Yuan stripped away the checks on his authority and even proclaimed himself Emperor for life in 1915. This was the ultimate act of overreach: a president of a republic crowning himself monarch. Yuan’s power grab quickly eroded China’s first experiment in republican governance. As one historian noted, “China’s first attempt at a democratic transition utterly failed” once Yuan dismantled the nascent constitutional system ( A Forgotten Experiment | British Journal of Chinese Studies ). Within a few years, the republic had collapsed into warlordism - a direct outcome of one man concentrating all power in his own hands.

American safeguards against executive tyranny

The framers of the U.S. Constitution, having just defeated monarchical rule, created a presidency with significant but strictly limited powers. Presidential authority is systematically checked by Congress and the Judiciary at every turn.

Presidents cannot unilaterally create or modify laws—all legislation requires Congressional approval. Executive orders and emergency powers remain subject to judicial review and congressional limitation. Congress controls funding, conducts oversight, and can impeach presidents who exceed legal boundaries. This structure embodies Madison’s principle that liberty requires no branch exercise another’s powers. Unlike in failed republics, American presidents cannot dissolve legislatures or rewrite the Constitution, even during crises. Washington himself warned in his Farewell Address:

the spirit of encroachment tends to consolidate the powers of all departments in one, and thus create… a real despotism.

This design ensures that any president attempting authoritarian measures would face immediate resistance from Congress, courts, states, media, and voters. While presidential overreach remains possible, the constitutional safeguards established by the Founders create substantially higher barriers against tyranny.

By design, an American executive who attempted Yuan Shikai’s or Hitler’s path would quickly run up against Congress, the courts, the states, a free press, and ultimately the voters. This doesn’t mean a president could never abuse power, but the hurdles are far higher because of the constitutional circuit breakers installed by the Founders.

Legislative Inaction: When Parliaments Fail to Check Tyranny

In a healthy republic, the legislature is meant to be a robust check on the executive. If the legislative branch becomes ineffective, cowardly, or complicit, an aspiring autocrat faces little resistance in taking control. The Founders understood that tyranny can arise not only from an over-mighty executive, but also from a failure of the legislature to assert its authority. As Madison observed, tyranny can spring from “the intrigues of the executive” if not adequately checked by a representative assembly. In Federalist No. 51, he argued each branch must have the will and means to defend its own powers, making “the legislative authority … to be divided” and balanced so it cannot be easily usurped.

The U.S. Constitution thus vests Congress with extensive powers and internal checks (two houses with different constituencies and terms) to ensure energy and independence in the legislative branch. These measures were intended to prevent legislative paralysis or surrender in the face of executive ambition.

Nazi Germany: The demise of Germany’s democratic legislature in the 1930s is a cautionary tale of legislative failure. The Weimar Republic’s Reichstag was crippled by political infighting and economic paralysis, enabling Hindenburg to govern through emergency decrees, bypassing parliament.

By 1933, the Reichstag had already surrendered much of its authority. When Hitler proposed the Enabling Act to abolish parliamentary oversight, legislators capitulated without meaningful resistance. Centrist and right-wing parties voted to transfer full legislative powers to Hitler’s cabinet for four years.

Though intimidation factored in—SS troops surrounded the building and opposition members were silenced—elected officials legally dissolved their own authority. This self-neutering removed the final check on Hitler’s power. The Reichstag became merely ceremonial while Hitler’s inner circle controlled lawmaking, a decisive step in democracy’s collapse.

Early Republic of China: In China’s short-lived 1912-1916 republic, parliament failed to prevent autocracy due to Yuan Shikai’s direct suppression.

Following the 1913 elections, the Chinese Parliament was tasked with drafting a constitution to limit presidential power. Yuan preemptively crushed this threat by forcefully dismantling the legislature. When lawmakers demonstrated independence, Yuan expelled opposition members en masse, stripping all 438 Kuomintang representatives of their seats and eliminating the majority party.

Without a quorum, parliament stalled, and by January 1914, Yuan dissolved it entirely, ending constitutional development. Unlike in Weimar Germany, Chinese legislators actively resisted—some even launching the “Second Revolution” uprising - but Yuan’s military quickly crushed this opposition. The Chinese Parliament’s fate demonstrates that constitutions are only as strong as the officials willing to enforce them; when legislators lack institutional strength to check executive overreach, written protections prove inadequate.

American safeguards in the legislature

The U.S. Founders prioritized legislative strength, recognizing Congress as the people’s true representative. They established it as co-equal - and initially even considering it preeminent - and equipped it with powerful checks against executive overreach.

Congress alone can declare war, control spending, and confirm appointments. Its bicameral structure prevents hasty legislation and resists factional domination. Madison’s principle that “ambition must counteract ambition” ensures each branch defends its authority when others encroach.

We’ve seen this system be effective before in American history:

• Truman’s steel mill seizure was blocked by the Supreme Court in Youngstown (1952).
• Andrew Johnson’s impeachment in 1868 - the first use of this Congressional power - checked his violation of the Tenure of Office Act
• Nixon’s impoundment of funds prompted Congress to pass the Budget and Impoundment Control Act (1974) and assert Congressional control over the purse

While this framework has generally succeeded, it depends on legislators actively using their powers. The Constitution provides tools but requires representatives with the courage to uphold their oaths regardless of party loyalty. This is a responsibility modern Americans must demand of their Congress.

Public Acquiescence: When Citizens Surrender Liberty for Security

The final (and perhaps most crucial) factor in a republic’s collapse is the role of the people themselves. Even the best-designed institutions can falter if the public either actively supports an authoritarian turn or passively allows it. Public acquiescence can take the form of voters electing anti-democratic leaders, or simply a population that - out of fear or despair - doesn’t resist the erosion of their freedoms.

The Founders recognized that no constitutional safeguards can save liberty if the people do not value and defend it. Ultimately, as Madison noted, “a dependence on the people is, no doubt, the primary control on the government”. At the same time, the Framers understood that in times of crisis, people might trade liberty for security. This is why they created “auxiliary precautions” - checks and balances, independent courts, federalism with powers resrved to the states, etc. - to secure rights even when popular sentiment wavers.

Still, a republic’s fate rests on its citizens’ vigilance. When Benjamin Franklin was asked about the Constitutional Convention’s result, he famously replied they had created “a Republic, if you can keep it.” This proviso underscores that public commitment is the ultimate safeguard. Franklin warned the government could:

only end in despotism…when the people shall become so corrupted as to need despotic government.

If citizens grow indifferent or excessively partisan, or prefer a strongman’s false comfort, no paper constitution will save the republic.

Nazi Germany: Weimar democracy’s collapse required both Hitler’s ambition and public acceptance of authoritarian rule.

Though the Nazis used terror against opponents, they also enjoyed genuine popularity. Many Germans willingly exchanged democratic freedoms for promises of economic recovery and national restoration. Millions, exhausted by unemployment and political dysfunction, embraced extremist parties.

Hitler explicitly promised both economic revival and “strong authoritarian government” - with many voters willing to sacrifice democracy for perceived strength and stability. Once in power, Nazi propaganda reinforced compliance by portraying Hitler’s leadership as superior to democratic division. When Hitler implemented radical measures (e.g. Night of the Long Knives or the Nuremberg Laws), public resistance was minimal.

By the time the true horrors of the Nazi regime became apparent, it was too late to effectively oppose it. Weimar’s fall demonstrates how democratic norms quickly erode when public faith falters. Economic crisis and national resentment created demand for a “strong hand” that the Nazis exploited. Hitler succeeded not merely through force, but through a population that initially accepted democracy’s dismantling from a mixture of hope, fear, and indifference.

Early Republic of China: In China’s case, public opinion is harder to gauge given lower literacy and limited mass politics, but evidence shows many Chinese elites and citizens accepted Yuan Shikai’s authoritarian turn, fearing continued instability.

Yuan’s 1913-1914 crackdown faced resistance from Sun Yat-sen’s supporters, but he also received significant backing from influential figures. The Progressive Party sided with Yuan against the Kuomintang, while reformers like Liang Qichao defended his harsh measures, calling rebels “more disastrous than deluge and wild animals”—prioritizing order over democracy. Tang Hualong even advocated “immediate extermination” of Yuan’s opponents, revealing that even educated elites accepted strongman rule as necessary stabilization.

The general public, particularly in northern provinces under Yuan’s military control, failed to defend parliament. After decades of imperial decline and civil conflict, many Chinese desired unity and strong leadership at the cost of republican principles. Only when Yuan declared himself Emperor did he lose support from provincial governors and military leaders. By then, the republic was effectively finished, collapsing into warlordism after Yuan’s death. China’s experience demonstrates how public acquiescence often stems from exhaustion—people may accept authoritarianism when they fear democratic instability more than dictatorial control. Without established democratic traditions, following a strongman became the path of least resistance.

American perspective on public vigilance

The United States was founded on a paradox: profound distrust of concentrated power, yet great trust in the ordinary citizen. The Founders believed an informed citizenry forms the foundation of a lasting republic.

Recognizing human fallibility, they designed a system encouraging participation while tempering sudden passions. Regular elections ensure accountability, while staggered terms and independent institutions prevent momentary majorities from permanently upending the system. Hamilton recognized that popular majorities can make mistakes, so the Constitution filters public impulses without thwarting public interest. Madison argued in Federalist 63 that the Senate could check “people’s momentary errors” through deliberation and long-term thinking.

The Bill of Rights protects fundamental liberties even if a fearful majority would abandon them. These mechanisms maintain freedom in good times and bad—when citizens are vigilant and when they aren’t. The Founders emphasized civic education, with Adams noting, “Liberty cannot be preserved without general knowledge among the people.”

The American system requires active public participation in safeguarding the republic. Citizens must vote, question leaders, and reject blind loyalty to individuals or parties. Franklin’s warning that government ends in despotism when people become corrupted implies each generation must earn its republic anew.

Modern Americans face this responsibility. Becoming polarized, apathetic, or fearful would repeat past republics’ failures. Our Constitution provides the framework, but depends on the people to enforce it. America’s democratic culture, while stronger than 1930s Germany or 1910s China, requires constant civic engagement and prioritizing country over party. Throughout our history, public courage—from voting out corrupt officials to exposing wrongdoing—shows a republic that has, thus far, chosen vigilance over complacence.

How the U.S. System Was Designed to Endure

The examples of Weimar Germany and early Republican China underscore why the U.S. Founders were almost obsessive about checks and balances. They knew from their study of history (including the ancient Roman Republic’s fall and the English Civil War) that giving any individual or group unchecked power was a recipe for disaster.

The Constitution’s separation of powers and federalism (splitting authority between state and federal governments) create multiple barriers to tyranny. As Madison noted, in the “compound republic of America,” power is divided both horizontally and vertically - a “double security” for the rights of the people. If an authoritarian movement were to capture one center of power, the others could resist.

For instance, even if the executive branch veers toward autocracy, Congress can block its agenda, states can refuse unconstitutional directives, and courts can invalidate illegal orders. Conversely, congressional demagogues face presidential vetoes and judicial review. This system of co-equal rivals, forced to cooperate but empowered to check each other was deliberately designed.

The American system also includes crucial safety valves absent in failed republics. Regular, free elections provide peaceful means to remove power-abusing leaders. Freedom of speech enables critics to raise alarms against authoritarian behavior before it’s too late. An independent judiciary upholds rule of law against authoritarian impulses. And our constitutional culture ensures that even ambitious politicians typically justify actions in legal terms rather than dismissing constitutional constraints outright.

This culture serves as a vital safeguard: when President Nixon trampled legal boundaries during Watergate, even members of his own party chose Constitution over cult of personality, forcing his resignation rather than allowing the rule of law to crumble. Today’s far deeper partisan divisions demand even greater moral courage - we urgently need leaders willing to risk political exile by standing against their own faction when constitutional principles are at stake, before our democratic guardrails collapse entirely.

Lessons for Today

These collapsed democracies aren’t distant curiosities - they are urgent warnings. The toxic combination that destroyed previous republics: social division, extreme polarization, charismatic demagogues, cowed legislatures, and citizens trading freedom for false security - they already casts shadows across our own landscape.

America has weathered democratic crises before and faces profound challenges now. Our survival depends entirely on whether our institutions and civic culture possess the resilience to withstand mounting pressures. The constitutional architecture the Founders designed remains brilliant, but like any structure, it deteriorates without constant maintenance, and answering hard questions:

• When an executive grasps for unconstitutional power, will Congress defend its authority with unwavering resolve—even against a president of their own party? Or will they, like the Reichstag, sacrifice democratic principles on the altar of partisan loyalty?
• When confronted with genuine national crisis, will Americans recommit to constitutional principles, or will we surrender to the seductive promise of a strongman who pledges to “do whatever it takes”?
• When courts face overwhelming pressure to validate unconstitutional actions in the name of “national security” or “emergency powers,” will they stand as the Youngstown Court did, or capitulate like Weimar’s judges?

We’ve resisted authoritarian temptations before: Washington rejected kingship by establishing the peaceful transfer of power; our military has maintained steadfast civilian subordination; and even after 9/11’s trauma, we maintained public debate over security measures and implemented sunset provisions on emergency powers.

Today’s fierce conflicts over executive authority, congressional oversight, and democratic norms aren’t signs of failure - they’re vital signs of a republic still fighting for its principles. A dying democracy wouldn’t bother with such debates; it would slip quietly into autocracy’s embrace.

And today, maybe more than ever, Washington’s warning against the ‘spirit of party’ remains relevant:

The alternate domination of one faction over another, sharpened by the spirit of revenge natural to party dissension…is itself a frightful despotism. But this leads at length to a more formal and permanent despotism.
