I see that the category 'Mountain Meadows Massacre' is categorized as American Indian Wars and Wars 1800-1899. This event occurred in the fall of 1857 in Utah during the period of the Utah War. I suggest removing American Indian Wars and instead applying category Utah War while retaining Wars 1800-1899 would be more correct. In fact, they majority of the attacking band/militia were non-native and no specific tribe has been officially identified as taking part in this event. Please let me know if you have need of further details. Thank you for considering my request, I look forward to your response.
