@JosjeT @andrewstroehlein Then what share did foreign assets make up of the whole from resources, food, work, inventions, technology, techniques, and ideas that didn’t come from their surroundings? The Viking empire did collapse and I assume it took much of the sailing, raiding, and exploration with it. Sweden produce ~80% of food domestically, ~20% imported. When most were farmers many communities and families were self sufficient on food, much would go bad during shipping.
