The Olive Branch: How a Tree Became Peace Itself
No plant on earth carries more meaning than the olive branch. Here is how a sprig of a Mediterranean tree became the world’s shorthand for peace and goodwill — and why, of all the trees they knew, the ancients chose this one.

Some symbols are invented; the olive branch was earned. It became the near-universal sign of peace not by decree but by three thousand years of use, running from Greek heralds through the Biblical dove to the flag of the United Nations. The story of how it got there is also the story of why the olive, of all trees, was the one that could carry it.
Ancient roots
In ancient Greece and Rome, a suppliant or a herald carried an olive branch to signal peaceful intent — to ask for mercy or to parley without weapons. Victors at the Olympics wore olive wreaths, and the tree was sacred to Athena, who in myth won the city of Athens by giving it the olive. To bring an olive branch was to come in peace, and everyone in the classical world understood it instantly. It was a shared language of gesture, older and more reliable than any treaty.
The dove and after
The image deepened in the Hebrew Bible, where a dove returns to Noah carrying a freshly plucked olive leaf — a sign the floodwaters had receded and life could begin again. That fused two ideas that have travelled together ever since: the dove of peace and the olive of renewal. From there the symbol ran straight into modern life. ‘To extend an olive branch’ means to offer reconciliation, and the olive branches on the flag of the United Nations, adopted in 1946, cradle the whole world.

Why the olive, of all trees
Here is the part worth pausing on, because it is not obvious. To the peoples who coined the symbol, the olive meant food, light, medicine and wealth wrung from poor, dry soil — and it lives for centuries, surviving fire and drought. Two qualities made it the perfect emblem of peace. First, it takes years to bear and is quickly ruined by war, so it belongs to stable, settled times; armies burned groves precisely because the damage lasted a generation. Second, it endures: a branch of it is not just ‘a plant’ but a promise of continuity and plenty. Peace, in the Mediterranean imagination, looks exactly like a tree that outlasts every war.
The branch, decoded
- In the classical world, carrying a branch signalled peace without a word.
- The dove-and-olive image fused peace and renewal, and has travelled together since.
- The tree was chosen because it means plenty and endurance, not merely calm.
- Its modern home is the UN flag and the phrase ‘extend an olive branch’.
How the olive became peace: common questions
Why is the olive branch a symbol of peace?
Because the olive takes years to bear and is quickly ruined by war, it belongs to stable times — and it endures for centuries, making a branch a promise of continuity and plenty.
Where does the symbol come from?
From ancient Greece and Rome, where suppliants carried olive branches for peace, and from the Biblical dove returning to Noah with an olive leaf.
What is the link to Athena?
In Greek myth Athena won the city of Athens by giving it the olive tree, so the tree was sacred to her and bound up with the city’s identity.
What does ‘extend an olive branch’ mean?
To offer reconciliation or make peace — a modern idiom drawn straight from the ancient gesture of carrying a branch in peace.
Is the olive branch on the United Nations flag?
Yes — the UN emblem, adopted in 1946, frames a world map with two olive branches as a symbol of peace.
It’s no accident the symbol is an olive. To the peoples who coined it, the tree meant food, light, medicine and wealth from poor soil — and it lives for centuries, surviving fire and drought. A branch of it isn’t just ‘a plant’; it’s a promise of endurance and plenty. Armies burned groves precisely because the wound lasted a generation, so a branch offered in peace meant the trees, and the life around them, would go on. Peace, in other words, looks like a tree that outlasts every war.
