It is a heavy thought. The idea that the most powerful person on the planet can be erased by a single person with a cheap weapon is, frankly, terrifying. We like to think of the Oval Office as this untouchable fortress of democracy, but history says otherwise. When people ask which US presidents have been assassinated, they usually expect a quick list of four names. And yeah, there are four. But the "why" and the "how" are way more unsettling than just the names on a bronze plaque.
The American presidency is one of the most dangerous jobs in the world. Statistically, it's brutal. We’ve had 46 presidents, and four have been murdered in office. That’s nearly a 9% mortality rate by homicide. Honestly, those aren't great odds for a career path.
The First Heartbreak: Abraham Lincoln (1865)
The Civil War was basically over. Lee had surrendered at Appomattox just days before. You’d think the country would have taken a collective breath, but the hatred was still vibrating under the surface. Abraham Lincoln wasn't just some politician; he was the guy who had held the Union together by sheer force of will.
On April 14, 1865, he went to Ford’s Theatre to see a comedy called Our American Cousin. He wanted to laugh. He deserved to laugh. But John Wilkes Booth, a well-known actor and Confederate sympathizer, had other plans. Booth didn’t just hate Lincoln; he thought killing him would somehow restart the war or save the South. He snuck into the state box and shot Lincoln in the back of the head with a .44-caliber Derringer.
It was messy. Booth jumped from the box, broke his leg on the stage, and shouted "Sic semper tyrannis!" (Thus always to tyrants). The weirdest part? Most of the audience thought it was part of the play. They just sat there. Lincoln died the next morning at the Petersen House across the street. Secretary of State Edwin Stanton famously whispered, "Now he belongs to the ages." It changed everything. Reconstruction became a vengeful, fractured mess because the one man who wanted "malice toward none" was gone.
The Forgotten Tragedy: James A. Garfield (1881)
If you ask a random person on the street which US presidents have been assassinated, they almost always forget James Garfield. It’s a shame. Garfield was brilliant. He was a former math professor who could write Greek with one hand and Latin with the other simultaneously.

He had only been in office for four months when Charles Guiteau shot him at a train station in Washington, D.C. Guiteau was a total delusional wreck. He thought he deserved a high-level diplomatic post in Paris because he’d given a few speeches for Garfield. When he didn't get it, he decided God told him to "remove" the President so the Vice President, Chester A. Arthur, could take over.
Here’s the kicker: the bullet didn't kill him. Modern doctors actually agree that if Garfield had been shot today, he’d have been out of the hospital in two days. But 1881 medicine was... questionable. Doctors literally stuck their unwashed fingers into the wound to find the bullet. They turned a small hole into a massive, infected cavern. Garfield suffered for 80 days in the blistering summer heat before dying of septicemia. His death was basically a slow-motion medical execution.
The Turn of the Century: William McKinley (1901)
By 1901, America was becoming a global superpower. William McKinley had just won the Spanish-American War and was feeling pretty good about things. He went to the Pan-American Exposition in Buffalo, New York, to shake hands with the public.
Leon Czolgosz, an anarchist who had lost his job during the economic Panic of 1893, was waiting in line. He had a revolver hidden under a handkerchief wrapped around his hand, looking like a bandage. When he got to the front, he fired two shots.
McKinley’s first instinct? He told the guards not to hurt the guy. "Easy with him, boys," he said. He died eight days later. This assassination is why we have the Secret Service protecting the President today. Before McKinley, the Secret Service mostly just hunted down counterfeiters. After this, the government realized they couldn't just let the President wander around handshake lines without a literal human shield.

The Day the World Stopped: John F. Kennedy (1963)
This is the one everyone knows. It’s the one that birthed a thousand conspiracy theories. November 22, 1963. Dallas, Texas. Dealey Plaza.
JFK was in an open-top Lincoln Continental. He was young, charismatic, and represented "Camelot." Then Lee Harvey Oswald—according to the Warren Commission—fired three shots from the Texas School Book Depository. The Zapruder film caught it all in grainy, horrifying detail.
The impact of JFK’s death can't be overstated. It was the first time an assassination played out in the age of television. People watched Walter Cronkite choke up on air as he announced the time of death. It felt like the end of American innocence. Whether you believe Oswald acted alone or there was a "grassy knoll" shooter, the reality is that the 35th President was gone in an instant, and the nation’s psyche was scarred forever.
Why Do People Keep Trying?
It’s not just the four who died. There have been dozens of attempts. Andrew Jackson had two pistols misfire on him at point-blank range (then he proceeded to beat the would-be assassin with his cane). Teddy Roosevelt got shot in the chest and finished his speech before going to the hospital. Ronald Reagan came within inches of death in 1981.
Why? Mostly, it's a toxic mix of mental illness and political extremism. These shooters often aren't masterminds. They are lonely, disenfranchised people looking for a shortcut to historical relevance. They see the President not as a person, but as a symbol they can smash to feel powerful.

The Lingering Effects on American Law
Every time a president is killed, the country changes.
- Lincoln's death led to a harsher Reconstruction that deepened the North-South divide for a century.
- Garfield's death ended the "spoils system" and gave us the Pendleton Civil Service Reform Act.
- McKinley's death gave us the modern Secret Service.
- Kennedy's death led to the 25th Amendment, clarifying exactly how the Vice President takes over and how to fill a VP vacancy.
History isn't just a list of dates. It's a series of shocks to the system. Understanding which US presidents have been assassinated helps you see why our government looks the way it does today. The security, the succession rules, the very way the President moves through the world—it’s all written in the blood of these four men.
How to Deepen Your Knowledge
If you want to actually understand the gravity of these events beyond a Wikipedia summary, there are a few things you should do. First, read Manhunt: The 12-Day Chase for Lincoln's Killer by James L. Swanson. It reads like a thriller but it's all true. For the Garfield saga, Destiny of the Republic by Candice Millard is essential—it explains the medical malpractice in a way that will make your skin crawl.
Finally, if you’re ever in D.C., go to the National Museum of Health and Medicine. You can actually see the lead probe used on Garfield and fragments of Lincoln's skull. It's macabre, sure, but it makes the history feel incredibly real. Don't just memorize the names; understand the moments that broke the country and how we put it back together.
