The 4th century was defined by the calendar of Earth as occurring from the year 301 through the year 400.
- The inhabitants of Vulcan engage in terrible and destructive wars including the use of atomic bombs, a result of the violent passions and emotions that govern the Vulcan people. It is a savage time, even by Earth standards. Myths from this period describe a terrifying weapon of war called the Stone of Gol that kills with the power of the mind. (TOS: "Balance of Terror", "Amok Time", "All Our Yesterdays"; TNG: "Gambit, Part II"; ENT: "Awakening")
- The Time of Awakening: Surak of Vulcan leads his people onto a path of peace and logic. (TOS: "Amok Time", "The Savage Curtain"; TNG: "Gambit, Part II"; ENT: "Awakening")
- A group of Vulcans who do not follow Surak's teachings of logic leave their homeworld in a wave of emigration. They will finally settle on the planets Romulus and Remus, coming to be known as the Romulans. (TOS: "Balance of Terror", "The Enterprise Incident"; TNG: "Unification II", "Gambit, Part II")
- The Debrune, an offshoot of the Romulans, establish an outpost on Barradas III. (TNG: "Gambit, Part I")
- According to Weyoun, "the Dominion has endured for two thousand years" as of 2372, i.e., since the 4th century. (DS9: "To the Death")
- The Jem'Hadar begin serving as the Dominion's front line of defense. (DS9: "What You Leave Behind")
- The Vidiian Sodality in the Delta Quadrant is ravaged by a deadly viral disease called the Phage. The Vidiians survive only by harvesting organs from non-Vidiians to replace their own tissues. (VOY: "Phage")
- The native civilization of Golana becomes extinct. (DS9: "Time's Orphan")

Background information Edit
- In "The Dogs of War", Weyoun 8 euphorically claims that "the Dominion hasn't surrendered in battle since it was founded ten thousand years ago." This seems to contradict Weyoun 4 in "To the Death", who states "The Dominion has endured for two thousand years [...]." That number seems to align with the Female Changeling, who commented that the Jem'Hadar had been the Dominion's first line of defense for two thousand years in "What You Leave Behind".

Furthermore, according to a line by Quark in DS9: "Little Green Men", Vulcans did not possess warp drives as of 1947. Yet, the book LUG: "The Way of Kolinahr" (p. 24) suggests the possibility that Sudoc's scientists had secretly developed the warp drive and that Tellus (who led the Romulan exodus) stole the prototype, which the Romulans later lost of in a civil war.

(LUG: "The Way of Kolinahr" p. 19 & 24; LUG: "The Way of D'era" vol.
