What happened to the Vikings Greenland colony?
Researchers are unsure of what became of the Vikings’ Greenland colonies. Some believe that the colonies collapsed as a result of a dramatically cooling climate. Others propose that colonists suffered from overpopulation, were overcome by indigenous groups and left for North America or Iceland, or that trade with Europe robbed the colony of extra resources. Most believe a combination of causes added to the deteriorating situation, with no single cause being the decisive factor.
