The Indians of California fought a lot among themselves (tribal wars) before the missions were built and that kind of warring was stopped. It wasn’t an Eden before the missionaries arrived.
Not just CA. All of the Western Hemisphere.
The Indians were no different than any other peoples inhabiting the planet.
They had advanced civilizations, built great cities, and huge empires. They enslaved others, had many wars, and some offered up human sacrifices.
The Left would all have us believe the Indians were early environmentalists, at one with nature, living in peace and harmony, singing kumbaya around the campfire.
What a crock of crap of course. I think it is from too much peyote in their peace pipes IMHO.
The Comanche originated in Wyoming, cousins of the Shoshone, and moved south and east when their proficiency with the horse allowed them to displace tribes native to that area.
The Pawnee moved north when they discovered corn would grow better in Nebraska than in Texas and northern Mexico, they could hunt buffalo in the off-season and there would be fewer conflicts with the Comanche.
Every tribe can tell similar stories.
