Most people think George Washington hated the idea of being a king so much that he just walked away after eight years and set a permanent rule. That's not exactly how it happened. Honestly, Washington was just tired. He wanted to go back to Mount Vernon. He was old, the political infighting was getting nasty, and he’d already given decades of his life to the public. By stepping down, he started a "gentleman’s agreement" that lasted for over a century. But it wasn't a law. It was just a vibe.
Then came 1940. Franklin Delano Roosevelt looked at the world—the Great Depression was still stinging and Hitler was marching across Europe—and decided the "two-term tradition" wasn't as important as stability. He won a third term. Then a fourth. He died in office, and Congress basically panicked. They realized that if a president was popular enough, or if the times were scary enough, someone could effectively become a "President for Life."
The 22nd amendment of us constitution was the solution. It’s the reason why, no matter how much people love or hate a sitting president today, that person has an expiration date.
The FDR Factor: Why We Actually Got a Written Limit
It’s impossible to talk about the 22nd amendment of us constitution without focusing on FDR. Before him, a few guys tried for a third round. Ulysses S. Grant wanted one but his party said no. Theodore Roosevelt actually ran for a third term under the "Bull Moose" ticket, but he lost.
FDR was different. He was a political juggernaut. When he broke the tradition in 1940, his opponents were screaming about "dictatorship." Even some of his own supporters felt weird about it. But the voters didn't care. They wanted the New Deal and they wanted a steady hand during World War II.
After FDR passed away in 1945, the Republican-controlled Congress made it their first big mission to make sure no one could ever do that again. They introduced the joint resolution in 1947. It took a few years to get the states on board, but by February 1951, it was officially part of the Supreme Law of the Land.
It’s kind of funny if you think about it. The amendment was essentially a "post-game" reaction to one specific man. Republicans wanted to prevent another Democratic dynasty, but interestingly, the first person it actually affected was Dwight D. Eisenhower—a Republican. He was still very popular at the end of his second term, but he had to pack his bags.
How the Math Actually Works (It’s Not Just 8 Years)
You’ve probably heard that a president can serve eight years. That’s the standard answer. But it’s actually more nuanced than that. The way the 22nd amendment of us constitution is written, the absolute maximum a person can be president is ten years.
How? It’s all about the "midterm" takeover.
If a Vice President (or anyone else in the line of succession) takes over because the sitting president dies, resigns, or is removed, the clock starts differently. If they serve two years or less of the previous person's term, that time doesn't count toward their two-term limit. They can still run for two full terms of their own.
Lyndon B. Johnson is the perfect example here. He took over after JFK was assassinated in 1963. Since there were less than two years left in Kennedy's term, LBJ was legally allowed to run in 1964 (which he did) and could have run again in 1968. He chose not to because the Vietnam War was tanking his popularity, but he could have. If he had won in '68, he would have served about nine years total.
On the flip side, if the VP takes over with more than two years left on the clock, they can only run for one more full term. It’s a bit of a mathematical safeguard to prevent someone from hanging onto power for nearly three full cycles.
Why Some People Hate the 22nd Amendment
Not everyone thinks this was a good idea. Some political scientists argue that it makes a president a "Lame Duck" the second they win their second term. Think about it. If you’re a member of Congress or a foreign leader, and you know the President is definitely leaving in three years, why would you cut a deal with them? You can just wait them out.
There’s also the "Democratic Will" argument.
If 60% of Americans want a specific person to keep being president, why should a piece of paper from 1951 stop them? That’s the core of the debate. Critics say the amendment is inherently anti-democratic because it limits the voters' choices. They argue that the "check" on a bad president should be the election itself, not an arbitrary term limit.
Ronald Reagan, interestingly enough, eventually came around to the idea that the amendment should be repealed. He thought it was a mistake to prevent the people from voting for whoever they wanted. Of course, he said this toward the end of his second term, so he might have been a bit biased. Harry Truman also called it a "monstrosity" and a "bad amendment," despite the fact that he was specifically grandfathered in and could have run for a third term himself (he tried briefly in 1952 but dropped out after losing the New Hampshire primary).
Could Someone Find a Loophole?
People love a good conspiracy theory. You might hear folks ask: "Could Barack Obama or Donald Trump come back as Vice President and then take over?"
The short answer is: Probably not, but the Constitution is a little bit blurry there.
The 22nd amendment of us constitution says no person shall be elected to the office of the President more than twice. The 12th Amendment says that no person "constitutionally ineligible to the office of President shall be eligible to that of Vice-President."
So, if you’ve already been elected twice, you are arguably ineligible to be President. If you're ineligible to be President, you can't be Vice President. Most legal scholars, like those at the National Constitution Center, agree this shuts the door on the "VP Backdoor" strategy. It would be a massive constitutional crisis if someone tried it, and the Supreme Court would likely shut it down instantly.
The Global Perspective
We take term limits for granted in the U.S., but they are actually a huge deal in global politics. Look at countries without them. You see leaders who stay in power for 20, 30, or 40 years. That usually leads to corruption because the person becomes more powerful than the institutions themselves.

The 22nd Amendment ensures that the office is bigger than the person. It forces a rotation of leadership. It brings in new ideas. Most importantly, it guarantees a peaceful transfer of power at a set interval. Even if a president is the most successful leader in history, they have to hand over the keys.
That’s a big deal.
What You Should Know Moving Forward
The 22nd amendment of us constitution isn't just some dry legal text. It’s a guardrail. It was born out of the chaos of the 1930s and 40s and serves as a permanent reminder that the U.S. is a republic, not a monarchy.
If you're following modern politics, keep these "Actionable Takeaways" in mind:
- Watch the "Lame Duck" Period: Pay attention to how a president's power shifts during their second term. You'll notice they often pivot to foreign policy or executive orders because they lose leverage with Congress.
- The VP Succession Rule: If a President ever leaves office early, check the calendar. If they’ve served more than two years, the new President is capped at one more election.
- Check Local Limits: While the 22nd Amendment only applies to the President, many states have similar limits for Governors. It’s worth checking if your state follows the federal model or allows for more "incumbency."
- Don't Fall for "Third Term" Rumors: Every few years, a rumor goes viral that a president is trying to overturn the amendment. To do that, you'd need two-thirds of Congress and three-fourths of the states to agree. In today’s polarized world, that is effectively impossible.
The 22nd Amendment effectively ended the era of the "Great Man" who stays forever. It turned the presidency into a temporary assignment rather than a lifetime achievement award. Whether that’s a good thing or a bad thing depends on how much you trust the voters versus how much you fear a tyrant. Honestly, most Americans seem pretty okay with the eight-year cap. It keeps things moving.
