Today marks the anniversary of Oklahoma becoming the 46th State in the United States of America. I'm reading a historical section of a local Oklahoma newspaper which claims, "During the American Civil War, most tribes in Indian Territory supported the South." I am curious as to the veracity of this claim. Did most tribes really support the South? If so, are there any insights into why any particular tribe would side with them? Likewise, any insights into tribal opposition of supporting the South?
