The bison was at the very centre of the way of life of the Plains
Indians.
The big mammal provided food, and also material to make tools,
clothes and the well-known tepees. The nomadic tribes followed
the bison in its seasonal migrations, but, at the same time, they
also had a communal, village way of life.
The appearance of horses in the plains of the North-West in the
first half of the 18th century revolutionized the way of life
of the region's inhabitants.
The Plains Indians quickly became matchless horsemen; the horse
became not only a vital means of travel, but also a symbol of
individual prestige in a community.
Together, horses and guns turned the peoples of the Plains into
efficient hunters and formidable warriors.
