Obviously there are numerous examples of warfare taking place, such as between the Navajo and Apache, but in the wider timeline, these periods seem few and far between. There has also been trends of native American languages seemingly deriving from the same family. To what extent were these groups interacting with each other? Was inter-tribal marriage typically common and/or accepted?
Thank you for your help :)
Is there any particular place, time period, or group of people you're interested in? Indigenous groups interacted in every way two groups of people can.
