Jutland horse 405 stud farms were devoted to their breeding in Denmark, but since that time, population numbers have dwindled. Though numbers dropped, a 2008 study of the 716 Jutland horses in the Danish studbook at that time concluded that little risk of the Jutland becoming extinct existed due to inbreeding or low genetic diversity. The study, which also included populations of the Knabstrupper and Fredericksborg breeds, theorized that the greatest loss to genetic diversity for horses in Denmark would be through the extinction of the Jutland breed, because of its genetic distance from the other two native breeds.

Jutland in c. 450 AD. The Angles themselves gave their name to the new emerging kingdoms called England (i.e., "Angle-land"). Saxons and Frisii migrated to the region in the early part of the Christian era. To protect themselves from invasion by the Christian Frankish emperors, the Danes built the Danevirke, a wall stretching across South Jutland from the North Sea to the Baltic Sea, beginning in the 8th century. The pagan Saxons inhabited the southernmost part of the peninsula at the Baltic Sea until the Saxon Wars in 772-804 AD in the Nordic Iron Age, when Charlemagne violently subdued them and
