During the "Time of Awakening" a Vulcan schism of those who "sought a return to savage ways" and "marched beneath the raptor's wings" (later the symbol of the Romulan people) perpetrate a cataclysmic nuclear attack upon Surak and his enlightened society.
The character of Surak in the Star Trek television series backstory, after up-ending the Vulcan people's violent tribalism with a philosophy of communal commitment to reason and logic, dies in the 4th century AD (based upon Earth's calendar, approximately 1,800 years before the events of the Star Trek: Enterprise episode "Awakening"), apparently of radiation poisoning caused by a nuclear attack that devastates Vulcan.
Archer later warns his companions that the Vulcan High Command intends to attack the Andorians, having learned this from Surak who he believes discovered it from some of Syrran's memories that got transferred over as well.
Archer and T'Pau succeed in taking the artifact to the corrupt Vulcan High Command in the Star Trek: Enterprise episode "Kir'Shara", resulting in its overthrow.
A character representing a physical re-creation of the "historical Surak" in his youthful maturity—fashioned by advanced alien technology from telepathically-recorded recollections and expectations held by Spock, appears in the original Star Trek series episode "The Savage Curtain", and is portrayed by actor Barry Atwater.
The fictional Surak's philosophy of rationalism with emotional mastery and its role as a cornerstone of Vulcan and Starfleet mythos has contributed a distinct philosophical component to the broader cultural influence of Star Trek.
