"Mexico Including California and Texas", Betts, John

This rare map shows the fascinating transitional period immediately prior to the Mexican cessation of the southwest in 1848 at the end of the Mexican American War. The early state of Texas is depicted extending west to the Rio Grande and encompassing Santa Fe and Taos. An interesting feature of this map is the pink shaded area between the Nueces River and the Rio Grande, which was claimed by both Texas and Mexico. This region remained under dispute during the entire duration of the Independent Republic of Texas, and also served as a trigger for the Mexican American War. New Mexico is named but not delineated, and extends across the border into Texas. The remaining land west of Texas is named Upper or New California, with sparse inland detail. Numerous Indian Tribes are located, and the courses of many major rivers are beginning to take shape.
