In 2155, Commander Jonathan Archer claimed to have received a private communiqué from Starfleet Command when he took over the command of the ISS Enterprise (NX-01). (ENT: "In a Mirror, Darkly") Archer blamed the rebellion on "criminals... sitting in their comfortable offices back at Starfleet Command." (ENT: "In a Mirror, Darkly, Part II") Starfleet Command, along with Starfleet, was likely dissolved when the Klingon-Cardassian Alliance conquered the former Terran Empire prior to 2370.
