The History of Assassination as a Political Tool

Political assassination is older than recorded history. The moment humans organized into power structures, some of those humans began calculating whether removing a specific individual might change everything. Sometimes they were right. More often, the results were far less predictable than the assassins imagined.

The history of assassination is not simply a list of targets and methods. It's a study in political desperation, in the belief that one death can redirect the course of events, and in how rarely that belief turns out to be correct in the ways the killers intended.

The Ancient World: Daggers and Dynasties

The word "assassination" itself comes from the Arabic hashshashin — a term applied to members of the Nizari Ismaili sect in 11th-century Persia and Syria who allegedly used targeted killings as a political and religious tactic. But the practice is far older than the word.

Philip II of Macedon, father of Alexander the Great, was assassinated in 336 BCE by one of his own bodyguards during the wedding celebration of his daughter. The reasons remain disputed — personal grievance, political conspiracy, possibly both. The immediate result was Alexander's accession to the throne, which altered the trajectory of the ancient world more profoundly than almost any other single event.

Julius Caesar's assassination on March 15, 44 BCE is the most famous killing in Western history. The conspirators — approximately 60 senators, led by Cassius and Brutus — believed that killing Caesar would restore the Roman Republic. Instead, Caesar's death triggered civil war, the destruction of the republic they were trying to save, and the rise of Augustus as the first Roman emperor. The assassination that was supposed to prevent monarchy produced it.

This pattern — assassination producing the opposite of the intended political outcome — recurs throughout history with remarkable consistency.

Medieval and Early Modern Europe: The Politics of Succession

In the medieval period, assassination was often a dynastic instrument. The murder of Thomas Becket, Archbishop of Canterbury, in 1170 — carried out by four knights who believed they were acting on King Henry II's wishes — created a martyr whose shrine became one of the most important pilgrimage sites in Europe, massively increasing the power of the church relative to the crown. Henry II spent years doing public penance.

The St. Bartholomew's Day Massacre of 1572 in France began as an assassination attempt on Huguenot leader Admiral Coligny that failed, then escalated into a state-sanctioned massacre of thousands of Protestants across France. Catherine de' Medici, the queen mother, made the political calculation that one targeted killing could solve a political problem. What it actually produced was decades of religious civil war and a trauma that shaped French confessional politics for generations.

William the Silent, Prince of Orange and leader of the Dutch revolt against Spanish rule, was killed in 1584 by a Catholic zealot. He became the first head of state assassinated with a handgun. His death accelerated the Dutch push for independence rather than ending it — the movement had grown too large to depend on any one man.

The 19th Century: Anarchism and the Propaganda of the Deed

The 19th century produced a wave of political assassinations driven by a coherent ideological framework. Anarchist and nihilist thinkers developed the concept of "propaganda of the deed" — the idea that a spectacular act of political violence could inspire mass uprising by demonstrating that the powerful were vulnerable.

Tsar Alexander II of Russia was killed in 1881 by members of the revolutionary group Narodnaya Volya (People's Will), after several previous attempts. The assassins succeeded in killing the man but catastrophically miscalculated the political consequences. Alexander II had been considering constitutional reforms. His successor, Alexander III, responded to the assassination by dramatically tightening autocratic control, launching pogroms against Jewish communities (who were blamed, falsely, for the assassination), and suppressing the reformist impulses that had been building. The assassination delayed Russian liberalization by decades.

President James Garfield was shot in 1881 by a man who believed he had been denied a diplomatic appointment. President William McKinley was killed in 1901 by an anarchist named Leon Czolgosz. These American assassinations produced the Secret Service's expanded presidential protection role and, in McKinley's case, elevated Theodore Roosevelt to the presidency — arguably a more consequential political transformation than anything the assassin intended.

Franz Ferdinand and the Trigger of World War One

The assassination of Archduke Franz Ferdinand in Sarajevo on June 28, 1914, is the most consequential killing of the 20th century in terms of immediate geopolitical impact. Gavrilo Princip, a 19-year-old Bosnian Serb nationalist, fired two shots that killed the heir to the Austro-Hungarian throne and his wife Sophie.

The details of the assassination are almost absurdly contingent. Princip and his co-conspirators had essentially failed that morning when their bomb attempt missed the Archduke's car. Princip was eating a sandwich at a deli when Franz Ferdinand's car took a wrong turn and stopped directly in front of him — the driver was trying to reverse out of a dead end. Princip stepped forward and fired.

The chain of events that followed — Austria-Hungary's ultimatum to Serbia, Russian mobilization, German declaration of war on Russia, the alliance system dragging in France and Britain — produced a war that killed approximately 20 million people, destroyed four empires, and created the conditions for World War Two.

Whether Princip's shots "caused" World War One is debated. Most historians argue that the underlying tensions — imperial rivalry, the alliance system, arms races, nationalist movements — made some catastrophic war likely. The assassination provided the specific trigger and the specific framing. The war it produced bore no resemblance to anything Princip or his handlers in the Black Hand society had imagined.

The 20th Century: State Assassination and Covert Operations

The 20th century saw assassination become a formal instrument of state policy, conducted through intelligence services with varying degrees of deniability. The CIA's documented assassination attempts and plots — against Fidel Castro (at least eight confirmed attempts), Patrice Lumumba of the Congo (successful, with Belgian cooperation), and others — represent a systematic use of killing as foreign policy.

The Senate Church Committee investigations in 1975 revealed the scale of American covert assassination programs and prompted a presidential executive order prohibiting U.S. government employees from engaging in political assassination. That order has been reinterpreted and worked around in various ways since, particularly in the context of targeted killing programs that developed after 2001.

The murder of Martin Luther King Jr. in 1968, and the assassination of Robert Kennedy two months later, were part of the most violent year in American political life since the Civil War. The psychological and political impact of those killings on American progressive politics — the sense of foreclosed possibility, the trauma of repeated loss — is difficult to quantify but real.

Why Assassination Usually Fails

The historical record on assassination as a political tool is largely one of failure, at least relative to the goals of the perpetrators. The structural analysis is straightforward: political movements, institutions, and historical forces are rarely dependent on a single individual. Removing one person typically hands their successor a political legitimacy boost, a martyrdom narrative, and a justification for exactly the kind of crackdown the assassins feared.

The cases where assassination succeeded — where removing one individual materially changed the political trajectory in the intended direction — are the exceptions. They tend to involve situations where the target genuinely was the indispensable person holding a fragile coalition together, and where the political environment was stable enough to absorb the transition without producing the backlash that martyrdom typically generates.

The lesson that most political actors have drawn from this history is not that assassination is morally wrong, but that it is strategically unreliable. The history of targeted killing is, in large part, a history of unintended consequences so severe that they overwhelmed whatever advantage the original act was supposed to provide.
