History
The
Texas Rangers are the earliest form of state law enforcement in the United States, first organized by
Stephen F. Austin in 1823. The original ranger force consisted of ten men charged with protecting settlers from Native American attacks. Though the rangers of this era are today considered law enforcement officers, they rarely wore badges and were little more than volunteers; the Mexican military was officially in charge of law enforcement in the then-Mexican state of Coahuila y Tejas. The Rangers later served as a paramilitary force on the U.S.-Mexico border and in several armed military conflicts, including the

. They continued to fill basic law enforcement and frontier protection roles until the close of the "wild west" era. In the early 1900s, they transformed into a criminal investigative agency. The history and legacy of the Texas Rangers has spawned numerous depictions in popular culture. The colloquial image of a Texas Ranger "always
ettingtheir man" has likewise made the Rangers a revered and highly competitive agency within law enforcement, with fewer than 1 in 100 applicants being considered for a single position.

John Jacob Cornwell was insistent upon having a State Police force which he said, "was mandatory in order for him to uphold the laws of our state." Part of the compromise was the name of the organization: "West Virginia Department of Public Safety" was the official name until 1995 when the name was changed to "West Virginia State Police" during the legislative session.
The federal government in the 1920s was generally distrustful of southern states establishing state police, fearing the agencies would be used to oppress black citizens from voting and exercising their civil rights. Additionally, southern states were non-union and had little need for such state police, as did some northern mining states. During this time the
Ku Klux Klan (KKK) was also on a resurgence. In response, the southern states established agencies to regulate the increasing problems related to motor vehicles and highway safety, such as licensure compliance, vehicle registration, speed enforcement, vehicular equipment safety, vehicle insurance laws and drunken driving. Over time, these agencies were vested with general police powers, but remained focused primarily on highway and vehicular law enforcement.

for example established a DMV motor vehicle theft investigations unit in 1921 to combat a rising problem with car theft, but the state realized a need for a larger, uniformed highway patrol agency to solely enforce traffic laws statewide. Local NC sheriffs did not have the personnel, resources or training to do so during that era, but did not want their powers usurped by a per-se state police agency. Thus, the
NC State Highway Patrol was established on July 1, 1929. Its original command staff was sent to the Pennsylvania State Police Academy for training. Upon completion, these lieutenants and a captain returned to NC and started the SHP with a training camp for new recruits at Camp Glenn, a WW1 abandoned army post in Morehead City. Chartered to enforce traffic laws only, in the early 1930s the NCSHP had added in its charter that it had powers to deal with among other crimes, bank robbery. This was done at the request of the federal government, so that local states could assist the FBI during the rash of bank robberies in the gangster era of the Great Depression in the 1930s. During this time, the FBI issued 100 spare Thompson .45 caliber sub-machineguns to the NCSHP, to prepare NC troopers to help the FBI combat the rash epidemic of bank robberies at the time. The expected scores of bank robberies never occurred in NC, instead being an epidemic confined to the sparsely-populated and vast areas of the Southwest, Midwest and Great Plains states from Texas to Minnesota. The guns were kept in the main SHP armory in Raleigh and never issued. The weapons were returned to the Federal government in the mid-1980s.

Types of state police agencies
In many states, the state police are known by different names: the various terms used are "State Police", "Highway Patrol", "State Highway Patrol", "State Patrol", and "State Troopers". However, the jurisdictions and functions of these agencies are usually the same, regardless of title. Some agencies' names are actually misnomers with respect to the work regularly done by their members. All but two state police entities use the term "
trooper" to refer to their commissioned members; California and New Mexico are the lone exceptions, using the term "officer" instead. New Mexico has commissioned and certified volunteer State Troopers in the
New Mexico Mounted Patrol

, a self-governing state agency, separate from the New Mexico State Police. (Until 2015, Arizona also used "officer", but has since switched to "trooper".) These titles are usually historical and do not necessarily describe the agency's function or jurisdiction. Colloquial or slang terms for a state trooper may include "troop," "statey," "stater," or—in
trucker slang—"Smokey", "full-grown bear", or "Polar Bear" if the police vehicle is all white. Some regional slang terms also exist for specific agencies.

The
Texas State Police was formed during the administration of Texas Governor
Edmund J. Davis on July 22, 1870, to combat crime associated with Reconstruction statewide in Texas. It worked primarily against racially based crimes, and included black police officers, which caused howls of protest from former slave owners (and future segregationists). It was dissolved by order of the legislature on April 22, 1873. The Texas Highway Patrol currently performs statewide police functions.
State police

Though many forces use the term "state police," its meaning is not consistent from agency to agency. In many places, it is a full-service law enforcement agency which responds to calls for service, investigates criminal activity, and regularly patrols high-crime areas. On the other hand, some state police agencies, despite the name, are strictly tasked with traffic enforcement, though their members usually retain full police powers; the

Highway patrol and highway police

Several agencies use the term "highway patrol," though this name can be misleading in some cases. Some highway patrol agencies are, as their name implies, dedicated to enforcing state traffic laws on the highways; a few are full-service state police agencies which regularly respond to calls and conduct inner-city policing functions; and yet others are a bridge, focusing primarily on traffic enforcement but providing general policing services when and where necessary. Their primary concern is enforcing motor vehicle laws, but they also assist with other incidents. These include riots, prison disturbances, labor related disturbances, and providing security at sporting events.
