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.
Frequently asked questions
Did the armistice end the First World War?
It stopped the fighting on 11 November 1918. The war was formally ended by the Treaty of Versailles, signed in June 1919.
What is the difference between an armistice and a ceasefire?
Both halt fighting. An armistice is generally the more formal and wider-reaching, while a ceasefire is often local, shorter or a step towards fuller talks.
Can a war be unfinished without a treaty?
Yes. The Korean War was halted by an armistice in 1953 and no peace treaty has followed, so it is sometimes described as technically ongoing.
