T'Pau was a Vulcan diplomat, judge, and philosopher who became one of the leading figures in Vulcan history. One of the most logical minds among her people, she had also been "absolutely ruthless in the application of her logic." (VOY: "Darkling")
T'Pau was born in 2122 on the planet Vulcan. (ENT: "The Forge") During the mid-22nd century, she was one of the leaders of the Syrrannite movement, which helped to reform Vulcan society by bringing forth the true teachings of the ancient Vulcan philosopher Surak. In 2154, T'Pau was falsely accused by the Vulcan High Command of the bombing of the United Earth Embassy, which had killed many Humans including Admiral Maxwell Forrest. The High Command falsified DNA evidence to indicate that T'Pau had planted the bomb. She became the de facto leader of at least part of the Syrranites following the death of Syrran. She was certain of her path and would let nothing stand in her way.
Syrran was killed in a sandfire storm while leading Captain Jonathan Archer and Commander T'Pol to the Syrrannite base, and before he died, he transferred the katra of Surak, through a mind-meld, into Jonathan Archer, who was investigating the alleged connection between T'Pau and the bombing of the United Earth Embassy on Vulcan. At first, she distrusted Archer and T'Pol, who accused her of the bombing. She accepted them once she found out that Syrran had transferred Surak's katra into Archer. She was willing to risk the death of Archer in an attempt to remove Surak's katra from him, whether or not he was willing to take the risks the extraction might pose to a Human brain. T'Pau attempted to transfer the katra from Archer, but due to Surak's resistance, could not do so. Later, the katra guided Archer to recover an artifact, the Kir'Shara. T'Pau also cured T'Pol of Pa'nar Syndrome by mind melding with her and undoing the damage done by a previous mind meld.
T'Pau was instrumental in helping Archer and T'Pol return to the High Command with the artifact, which contained the original writings of Surak. Their goal was to demonstrate, with the artifact, that the Syrannites were not violent, and that Vulcan civilization had strayed from the teachings of Surak, whose philosophies had brought peace to a war-torn Vulcan 1,800 years earlier. These events led to the dissolution of the High Command and the dismissal of the traitor V'Las from his post as administrator. (ENT: "Awakening", "Kir'Shara")
T'Pau later became a high-ranking minister in the new Vulcan government. One of her first acts as minister was to deploy twenty-three ships to aid Captain Archer in detecting a Romulan drone ship. (ENT: "United")
