What is the country of origin of the Spanish Mustang?

The Spanish Mustang is recognized for its unique lineage that traces back to early Spanish horses brought to the Americas by explorers and settlers. These horses adapted to various environments in the New World, particularly in the United States, where they became an integral part of local ranching and riding culture. The term "Spanish Mustang" highlights this connection to the Spanish ancestry while emphasizing their development in the United States. Their heritage includes influences from the various breeds that mixed over centuries, but the primary factor in their identification as Spanish Mustangs lies in their descent from those original Spanish horses, making the United States their country of origin.
