Notable examples are the Mongols of Mongolia, the Scythian and Turkic nomads of Central Asia, the Plains Indians, the Guaycuru peoples of the Gran Chaco, and the Mapuche and Tehuelche of Patagonia[1] after horses were imported from Europe, particularly from Spain, during the 16th century.
History offers many examples of horse cultures, such as the Huns and other peoples in Europe and Asia.
For example, the arrival of the horse in the Americas altered the cultures of the Native Americans in the Great Plains, the Gran Chaco and Patagonia.
The horse increased mobility; the ability of the horse to cover a lot of ground in a very short period of time allowed native people to easily move from place to place, bringing on a nomadic shift in their culture, with an impact on transportation, trade, hunting and warfare.
Social structures of the community also had to shift to accommodate the physical space for horses to graze and feed easily.
