There have been proposals to designate a state horse in Oregon as well as in Arizona (where an ongoing campaign sought to designate the Colonial Spanish Horse as the state horse prior to the state centennial in 2012), but neither proposal is yet successful.
Others, including the Tennessee Walking Horse and the Missouri Fox Trotter, include the state in the official breed name.
School children have lobbied for the cause of some state horses, such as the Colonial Spanish Horse being named the state horse of North Carolina due to the presence of the Spanish-descended Banker horses in the Outer Banks,[3] while others have been brought to official status through the lobbying efforts of their breed registries.
Such items usually are designated because of their ties to the culture or history of that particular state.
In addition to being state symbols in their own right, horses have also appeared in state symbols; for example, a horse's head appears on the seal of New Jersey.
