Welcome to History Hub,
This is not an answer to your question but
it reminded me of a vintage song.
"I fought the law and the law won."
I guess that could have been the reason.
Dear Ms. Woods,
Thank you for posting your request on History Hub!
We also located a website of the Library of Congress titled The American West, 1865-1900 that may be useful.
Plus, we suggest you review the online publications available through HathiTrust Digital Library. Using the search term American Frontier, we located several books including The Last American Frontier by Frederic Logan Paxson and The disappearance of the frontier between 1870 and 1890 by Marion Eleanor Moore.
Lastly, we suggest viewing the National Cowboy Museum Explore the West website.
We hope this is helpful. Best of luck with your research!
The concept of the "Wild West" is one that is so steeped in legend and mythology that there really is no solid answer to that. Many of the ideas associated in popular culture with the "Wild West" are exaggerations and distortions of what things were actually like to begin with, and you don't offer any definition of what changes constitute the end of the "Wild West" that would allow people to offer an explanation.
However, it is worth pointing out that wives and churches were present in the westward expansion of the Black and white, English speaking American population from the very beginning, not to mention the fact that they could also be found among the Spanish speaking population present before and during the time period commonly associated with the "Wild West" in fiction. Likewise, wives were found among the Native American tribes, as were both Christian churches and various indigenous forms of religious expression.
