1800s US History and Wild West Books

Hello, everyone!

Recently, I've been wanting to read and learn more about the 1800s in the US.
I'm curious about the wild west, the Native Americans, slavery, how people were living, the expansion west, the Civil War, etc…
I'm mostly interested in non-fiction, but would also be open to a well-written fiction novel that takes place during this time period. I'm not too interested in books that are "nitty gritty" political (i.e. I'm not terribly interested in reading a biography/memoir of a political figure).

If anyone has any suggestions, please let me know!
