When the Spanish brought horses to their rancheros in what is now Mexico, the natives learned how to wrangle and raise horses. The spread of the horse culture in the Southwest started about 1750 or so and finally reached the Sioux in Minnesota about 1830.
The natives then created the idea that stealing horses was a sign of strength and war prowess, akin to the theft of cars today by gangs.
For more info, search ‘when did Indians get horses?’ or read contemporary accounts of native life in books on Washakie, Geronimo, Red Cloud, Black Elk.
Just think, if the gun control folks win out we’ll
have to go back to blunt trauma again...
