The settlers had to make hay, protect livestock through long winters, obtain iron and other imported goods, construct buildings from stone and turf, and maintain enough contact with the outside world to keep their society supplied.

And yet they did it.

Then, sometime in the fifteenth century, the Norse presence disappeared.

The word ‘vanished’ can be misleading.

It makes the event sound instantaneous, as though thousands of people woke one morning and simply ceased to exist.

Archaeology does not support such a clean ending.

The evidence points instead toward a long process in which environmental stress, economic change, sea conditions, changing trade, demographic pressure, and the limits of a small isolated society interacted with one another.

The real mystery is therefore more interesting than a simple disappearance.

How did a community capable of surviving in Greenland for centuries reach a point where survival there was no longer worthwhile—or perhaps no longer possible?

And if the people left, where did they go?

If they died, why is there so little evidence of a catastrophic end?

And why did their society fail while the Inuit societies of Greenland continued?

To answer those questions, we have to stop imagining the Norse as a frozen snapshot of ‘Vikings’ and instead see them as ordinary families trying to make a life at the far edge of the medieval North Atlantic.

The geography itself explains much of the story.
