The Vulcan High Command existed at least as early as 1957. In that year, a Tellarite freighter relayed a distress call to the High Command from a Vulcan research team stranded on Earth. (ENT: "Carbon Creek")
In 2151, the High Command reassigned T'Pol as sub-commander on board Enterprise NX-01, to act as a "chaperone" for its first mission. It was a prerequisite for the High Command in order to provide the Humans with Vulcan star charts and the Klingon linguistic database. (ENT: "Broken Bow") Later that year, T'Pol's presence led Thy'lek Shran to suspect that Humans took orders from the Vulcan High Command. (ENT: "The Andorian Incident")
In May of 2153, however, the High Command ordered T'Pol (via Ambassador Soval) to return to Vulcan rather than join Enterprise on its mission into the Delphic Expanse. T'Pol resigned her commission to stay on Enterprise. (ENT: "The Expanse")
In 2154, V'Las, head of the High Command, planned to attack Andoria, tricking the Vulcan High Council into believing that the Andorians were developing a planet-destroying weapon based on Xindi technology. (ENT: "Awakening") After Enterprise thwarted that incident, the High Command was disbanded, ending their diplomatic influence on Earth's decisions. (ENT: "Kir'Shara")
Upon this occasion, the newly-instated minister T'Pau began cleaning house, which resulted in many former High Command ships being undercrewed by the time of the Babel Crisis. During that incident, she was only able to dispatch twenty-three starships to add to a combined Andorian-Human-Tellarite intercept fleet. (ENT: "United")
In the 2240s, following the bombing of the Vulcan Learning Center by logic extremists, The High Command was about to be alerted by Sarek and Amanda Grayson when their ward Michael Burnham ran away from home. (DIS: "Point of Light")
In 2257, the Vulcan High Command asked Ambassador Sarek to work with Starfleet in assembling a Federation task force in deciphering the red bursts that the USS Enterprise was investigating. (DIS: "Brother")

Others and unknown
In the first draft script of ENT: "Fortunate Son", the Vulcan High Command was mentioned as having been contacted about diplomatic difficulties between Starfleet and the Nausicaans, caused by the activities of Nausicaan pirates operating in a particular sector. According to Admiral Forrest, however, the High Command hadn't been of much assistance because the Vulcans didn't have formal relations with the Nausicaans.
In the script of ENT: "Awakening", the exterior of the Vulcan High Command building was described as "an imposing structure in the midst of a large Vulcan metropolis," and a "conference chamber" inside the building was described as "a regal setting, furnished with a conference table and monitors."
