A pre-warp civilization was any society or culture that had not yet become a warp-capable civilization; that is, one that has not discovered and utilized faster-than-light spaceflight like the warp drive. Pre-warp cultures could range in technology level from extremely primitive, such as a pre-industrial society; to that of Earth in the mid-21st century, where spacecraft utilized sublight technology. (Star Trek Into Darkness; Star Trek: First Contact; TOS: "The Omega Glory")
The Federation sometimes used an industrial scale and a technological rating to assess pre-warp civilizations. For example, the natives of Sigma Draconis III had, as of 2268, an industrial scale rating of B – equivalent to Earth in 1485 – and a technological rating of 3. (TOS: "Spock's Brain") Another scale was Richter's scale of cultures, which might assign a rating of class D- to an agrarian culture. (TOS: "Errand of Mercy")
The Federation's Prime Directive interdicted any disturbance of such civilizations, including any form of contact, until a culture had independently proven its warp-capability. Otherwise, any involvement in the development of pre-warp societies could result in the contamination of their culture, thereby altering their natural evolution. Usually pre-warp civilizations were limited to their homeworld; however, their technical abilities could be sophisticated enough to expand throughout their star system or even beyond. (ENT: "Dear Doctor"; TOS: "Patterns of Force"; Star Trek: Insurrection)
The Federation did allow limited covert research to be conducted on pre-warp civilizations, usually by means of a duck blind. (TNG: "Who Watches The Watchers"; Star Trek: Insurrection) Observation teams could also be placed among a civilization as a prelude to first contact. (TNG: "First Contact")
In the 32nd century, the Emerald Chain crime syndicate was notorious for contacting pre-warp civilizations in distress, such as the Kwejian, and offering "assistance" in the form of predatory deals. Such civilizations usually collapsed as a result. (DIS: "The Sanctuary", "There Is A Tide...")
