What Catiline tells us about Trump and democratic decline

Donald Trump is often treated as a heretic, but history shows otherwise. William J Dominik writes that the rise of Catiline in Ancient Rome showed how oppressed republics could tolerate lies, division and political decay.

HISTORY RARELY announces his return. Often, it reopens cracks in political systems already weakened by neglect.

Familiar patterns reemerge under changing conditions, with enough novelty to make recognition difficult. When institutions weaken, trust weakens, and politics is replaced by anger, republics produce figures who thrive on disorder rather than consistency.

There was such a figure in the last decades of the Roman Republic. Lucius Sergius Catilina. The obvious equivalent in the United States today is the President Donald Trump. The purpose of the parallel is not temperament or ostentation, but function; is what such figures do to already oppressed political cultures.

Trump’s appeal is based on a stance of constant grievance. He presents himself as a representative of those who have been wronged by elites and institutions that no longer inspire trust. His rhetoric is not aimed at persuasion, and certainly not at politics. It aims not to manage conflict, not to perpetuate it, but to mobilize it.

Sensitivity becomes expendable, anger becomes essential, and loyalty becomes more valuable than competence. Politics becomes a site of constant agitation, where attention is the main currency and conflict is the main product.

In this context, Trump’s relationship with the truth is structural. Inaccuracies function as unifying tools, not as mistakes that need to be corrected. Elections are declared stolen without any evidence, judicial decisions are rejected as corrupt, and journalists are declared enemies. Repetition helps. What starts with anger turns into familiarity and then into habit. This pattern has manifested itself in repeated claims of election fraud, denigration of courts and officials, and the transformation of routine procedures into scenes of permanent emergency.

roman historian SallustWriting during the Republican period in the 1st century BC, he offers a strikingly similar diagnosis in his own work. War with Catiline. Sallust does not isolate Catiline as an aberration but situates him within a society already eroded by debt, inequality, and corruption after decades of civil conflict. Catiline appears as a symptom rather than a cause; a figure rising through an already compromised political structure.

Catiline’s success lay in his ability to organize resentments. Promising renewal while accelerating division, he presented himself as the voice of the excluded as he pursued power without restriction. His claims did not require credibility; they just needed to resonate with a population that no longer trusted the ruling class. Sallust’s judgment is harsh: Catiline was not an interruption of Republican life but a consequence of its corruption.

Trump’s politics follow a similar logic. His lies serve as tests of loyalty rather than assertions of truth. Acceptance signals loyalty; rejection indicates hostility; correction becomes persecution; and fact-checking is recast as partisan aggression. Truth ceases to function as a common civic reference point and becomes another weapon in a broader cultural struggle.

Trump’s racism and bigotry operate within the same structure. These are not random errors, but signaling devices. Immigrants are portrayed as criminals and invaders, Muslims as threats, black and brown communities as sources of disorder, and LGBTQ+ individuals as cultural dangers. Complex realities are reduced to opposing identities and in doing so direct anxiety towards established goals.

Persecution follows. Public ridicule of the defenseless, humiliation of dissidents, and punitive policies present themselves as originality and power. Compassion is dismissed as weakness, restraint as hypocrisy. Over time, this reversal lowers the moral threshold of political life and normalizes behavior once deemed disqualifying.

Sallust highlights how Catiline exploited humiliation among those who felt excluded from the rewards of the Republic. Trump’s rhetoric pulls off the same maneuver, insulating power from scrutiny by directing economic insecurity and cultural unrest at convenient enemies. Resentment becomes a renewable resource that can sustain loyalty even in the absence of success.

If Sallust explains the conditions that make demagogues possible, Cicero It shows how institutions respond when these conditions become threats. During his consulship in 63 BC, Cicero exposed Catiline’s conspiracy in speeches known as “The Guardian”. Catilinarian Speeches. Cicero frames Catiline as an enemy within the walls of Rome; this is an entity that justifies extraordinary attention and action. He speaks not only as an orator, but as the protector of the Republican order; For him, exposure and denunciation are the means to stop the collapse.

The conspiracy was brought under control. Catiline fled Rome in late 63 BC, raised an army, and died in battle the following year. But Cicero’s response raises a recurring dilemma. The confidence of institutions to identify enemies and authorize exceptional measures can deepen the habits of fear exploited by demagogues. Catiline is defeated, but trust is not restored. The Republic survives without being able to resolve the conditions that made the crisis possible.

Modern American politics has followed a similar line. Trump presents himself as simultaneously powerful and persecuted. Responsibility is reshaped as oppression; legal review as conspiracy; and personal grievance as political principle. Corruption is normalized as public officials are treated as personal property. Loyalty is rewarded, dissent is punished, and responsibility is deferred.

Trump’s durability lies not only in the election results but also in the political culture he has reinforced. Disdaining the truth becomes strategy, racism is reframed as outspokenness, cruelty is mistaken for strength, and corruption is excused as cunning. While civil language hardens into insults and threats, politics turns into a war of identity instead of collective self-governance. This is not just a matter of individual character; It is a test of republican endurance.

Sallust ends his account of Catiline with an implication that history will soon confirm. The Roman Republic survived the conspirator, but not the conditions that created it. A generation later, after cycles of internal violence, the Republic surrendered to autocracy.

This is the warning to heed. Trump doesn’t need to overthrow the state to harm it. The harm comes from habituating citizens to lies, division, oppression, and disdain for democratic norms. Catiline fell on the battlefield; The Roman Republic disintegrated more quietly, after the habits that had sustained it had already eroded.

History does not predict outcomes but clarifies risks. Republics rarely collapse in a single dramatic moment. They gradually weaken as trust weakens, standards fall, and spectacle replaces judgment. Political structures continue to exist, but the habits that sustain them are eroded until the republic falls.
