The Vulcan High Council, also known as the Vulcan Council, was the body of elders tasked with protecting the Vulcan people's history. It was also the body that made the decision for Vulcan to join the United Federation of Planets by signing the Federation Charter. (Star Trek; ENT: "These Are the Voyages...")
In 2256, the High Council revealed to Admiral Terral that Sarek had been lost while en route to a secret meeting with two Klingon Great Houses. (DIS: "Lethe")
In 2381, T'Lyn requested to accompany D'Vana Tendi to the wedding of her sister D'Erika, so as to prepare a report on Orion rituals for the High Council. She abandoned the report upon realizing that Tendi did not want the details of their experiences disseminated. (LD: "Something Borrowed, Something Green")
Alternate reality[]
During Nero's attack on Vulcan in 2258, the High Council retreated into the katric ark in an attempt to preserve the cultural substance of the Vulcan civilization. After it became clear that Nero's attack would destroy Vulcan, Commander Spock beamed to the surface to rescue the Council, amongst whom were his parents, and escorted them out of the ark so the USS Enterprise crew could obtain a transporter lock. Exiting the ark onto a cliff which was on the verge of collapsing, Spock and the Council were beamed aboard the Enterprise, but Amanda Grayson fell to her death when the cliff gave way. (Star Trek)

V'Las, leader of the Vulcan High Command, was said to be unable to rule without consent of "the council". This may indicate that the High Council coexisted with the High Command.
