An armistice is an agreement to stop fighting — a halt, which can be temporary and does not settle anything. A treaty is the binding legal agreement that formally ends a war and sets its terms. The gap between them is real: the First World War's armistice was signed in November 1918, but the war was formally ended by the Treaty of Versailles in June 1919.
The core difference
- armistice — the guns stop. An agreement to cease hostilities, which may be temporary and leaves the underlying dispute untouched.
- treaty — the war ends. A formal, binding agreement setting out terms: borders, reparations, obligations.
Why the distinction is not academic
A conflict can sit between the two for years. The Korean War was halted by an armistice in 1953 and has never been closed by a peace treaty, which is why it is sometimes described as technically unfinished. The words describe genuinely different legal states.
Origins
Armistice is built from Latin arma, weapons, and -stitium, a stopping — literally a standing-still of arms. Treaty comes through French from Latin tractare, to handle or negotiate, the same root as treat.
Related terms
A ceasefire is usually more local or more temporary than an armistice. A truce is looser again and may be informal.
