If you read the Bible, Old Testement law had the Women’s tents where they went during that time.
My bride at first thought that was horrible, and then realized it would mean the husbands weren’t around to make them mad.
Like the Children of Israel, many of these Tribes were displaced from their homelands and/or escaping slavery.
Just as one example, the Siouxian tribes lived in the Ohio River Valley before moving into the Plains. The Mandan branch pretty much took up farming where they left off because they moved to a remote area of the country (Missouri River Valley of present North Dakota) where they were left alone for the next 3-4 centuries.
The main body of the Sioux, on the other hand, took up the nomadic hunter-gather lifestyle because they took up closer and more desireable lands in modern day Iowa, Wisconsin and Minnesota where they were constantly being displaced by more aggressive tribes (such as the Chippewa) moving west.
