Comancheria 

I have several problems with this section and think it needs to be at the very least removed:
It is not specific to Spanish Texas, which is the subject of this article.  The section covers a broad range of time that includes Mexican Texas, the Republic of Texas, and the state of Texas.  That is overly broad and makes it difficult to see exactly how this relates to Spanish Texas.
This relies on a single source, which leads to questions about potentially being POV or not mainstream.
