Fehrenbach explains the Rangers' uniqueness: The unique characteristics that the Rangers adopted during the force's formative years and that give the division its heritage today-characteristics for which the Texas Rangers would become world-renowned-have been accounted for by the nature of the Rangers' duties, which was to protect a thinly populated frontier against protracted hostilities, first with Plains Indian tribes, and after the Texas Revolution, hostilities with Mexico.
The origins of today's Texas Ranger Division trace back to the first days of Anglo-American settlement of what is today the State of Texas, when it was part of the Province of Coahuila y Tejas belonging to the newly independent country of Mexico.
