The Texas Rangers are a law enforcement agency with statewide jurisdiction in Texas, often regarded as a symbol of justice and frontier law enforcement. Established in the early 1830s, they have played a crucial role in the development of criminal justice policy in Texas, evolving from a group of volunteer militiamen into a professional investigative agency. Their history is marked by significant contributions to crime fighting, border security, and the enforcement of law during tumultuous times in Texas history.
