All Arabian horses have one region of origin.
The significance of the Spanish Arabians ancestry is the selection process that gave strong importance to good dispositions. Mares that rejected or savaged foals or even were disruptive in the mare band, as well as untrainable, obstreperous stallions, were rigorously culled from the gene stream. After all, these horses would be military mounts or working horses - they had to be reliable under difficult conditions. Presently in the USA we don't require cavalry mounts or messenger mounts to cross searing deserts while carrying essential documents. But in a world that presents us with plenty of negative stress, those who have an equine friend like one of these exciting yet peaceful Spanish Arabians or their offspring has one of the best friends of any species.
