Presidential term limits & the 22nd Amendment
A U.S. president can serve two terms — but that limit is younger than the country. For most of American history it was only a tradition; it became a hard rule of the Constitution only in 1951, after one president served four terms. This is a plain-language reference to how that happened and what the limit actually is. Neutral by design: we explain the mechanism and link the sources.
In one sentence For ~150 years the two-term limit was just an unwritten custom George Washington started; Franklin D. Roosevelt broke it by winning four times (1932–1944), and the country responded with the 22nd Amendment (ratified 1951), which now legally caps a president at two elected terms.
What the term limit is
A term limit is a cap on how many times the same person may hold an office. For the U.S. presidency the cap is two terms (each term is four years). Crucially, that cap has two very different chapters: from 1789 to 1951 it was a tradition with no legal force, and since 1951 it has been constitutional law — the 22nd Amendment.
The original Constitution set a president's term at four years but placed no limit on how many terms one person could serve. The Framers debated it and deliberately left it out — some thought re-eligibility kept a president accountable to the voters.
Washington's two-term tradition
The two-term custom traces to George Washington, who declined to run a third time and stepped down in 1797. Later presidents treated "two and out" as a self-imposed republican norm — a guard against any one person accumulating too much power — even though nothing in law required it.
The norm held for well over a century, but not for lack of trying to break it. Ulysses S. Grant sought a (non-consecutive) third term in 1880, and Theodore Roosevelt ran again in 1912 after sitting out a term — both were turned back by their party or the voters, not by any rule. The tradition survived because presidents chose to honor it, or the electorate enforced it.
How FDR broke the norm
Franklin D. Roosevelt won the presidency in 1932 and 1936, then did what no one had done before: he ran for and won a third term in 1940 and a fourth in 1944. Nothing in the Constitution stopped him — only the tradition, which he broke.
The moment mattered. The 1940 campaign came as World War II engulfed Europe, and 1944 fell in the thick of the war. A "don't change horses midstream" argument — amid the Great Depression's tail and then a global war — persuaded enough voters to keep re-electing him. He died in April 1945, months into that fourth term.
See it in the record on Franklin D. Roosevelt's profile — four terms, 1933–1945.
The 22nd Amendment
One person holding the office for twelve years prompted a lasting reaction. Congress proposed the 22nd Amendment in 1947, and the states ratified it in 1951, turning Washington's gentleman's agreement into hard constitutional law.
A tidy irony runs through the story: Washington created the norm by walking away, FDR ended it by staying, and the amendment made the custom permanent — so FDR is precisely why the written limit exists.
The exact rule today
The 22nd Amendment is more specific than "two terms." Its two core rules:
| Rule | What it means |
|---|---|
| Two elected terms | No person may be elected president more than twice. |
| The 10-year ceiling | Someone who succeeds to the presidency (e.g. a vice president who takes over) and serves more than two years of another's term may be elected only once more — a maximum of about 10 years total. If they serve two years or less of the inherited term, they may still be elected twice. |
The terms need not be consecutive — a president can serve, leave, and be elected again, as long as the total number of elected terms stays at two. The amendment limits election to the office, and applies only to the presidency.
Note on how CivicGate counts "terms": a president's profile shows the number of four-year terms they served during (any part of), which is why FDR reads as four and a mid-term successor may read as two despite winning fewer elections — it's the tenure, not the election count.
What isn't term-limited
The presidential cap is unusual in the federal government. Members of Congress — U.S. Representatives and Senators — face no term limits at all; they may be re-elected indefinitely. Federal judges serve "during good behavior," effectively for life. Term limits for governors and state legislators vary state by state — some cap them, many don't.
So the two-term presidential limit is a specific, deliberate exception, adopted in direct response to a specific history — not a general rule about American office-holding.
