Iceland has never allowed horse imports since the year 982 AD, when the Icelandic parliament banned them outright. That ban created one of the purest horse populations on the planet. It also made something else just as valuable. Icelandic horses grew up without exposure to many common equine diseases. The local horse population lacks immunity, and an outbreak could spread fast across farms, valleys, and riding centers. One infected horse returning home could trigger a crisis.
