Icelandic horses

From an article on Icelandic Horses:

"The Icelandic horse is a breed of horse that has lived in Iceland since the mid-800s, having been brought to the island by Viking settlers.

"There are roughly 100,000 Icelandic horses in Iceland, and relatively few abroad, owing in large part to centuries-old Icelandic legislation that prevents any Icelandic horse from returning to the island once it has been taken to another land."
